STINGRAY cameras STINGRAY cameras IEEE 1394b With the new Stingray, Allied Vision Technologies presents a wide range of cameras with IEEE 1394b interfaces. Moreover, with daisy chain as well as direct fiber technology they gain the highest level of acceptance for demanding areas of use in manufacturing industry. Image applications Allied Vision Technologies can provide users with a range of products that meet almost all the requirements of a very wide range of image applications.
Conformity Conformity Allied Vision Technologies declares under its sole responsibility that all standard cameras of the AVT Stingray family to which this declaration relates are in conformity with the following standard(s) or other normative document(s): • CE, following the provisions of 2004/108/EG directive (Stingray board level cameras do not have CE) • FCC Part 15 Class B (Stingray board level cameras do not have FCC) • RoHS (2002/95/EC) CE We declare, under our sole responsibility, that the previou
FireWire FireWire Overview FireWire provides one of the most comprehensive, high-performance, costeffective solutions platforms. FireWire offers very impressive throughput at very affordable prices. Definition FireWire (also known as i.Link or IEEE 1394) is a personal computer and digital video serial bus interface standard, offering high-speed communications and isochronous real-time data services. FireWire has low implementation costs and a simplified and adaptable cabling system.
FireWire Why use FireWire? Digital cameras with on-board FireWire (IEEE 1394a or 1394b) communications conforming to the IIDC standard (V1.3 or V1.31) have created costeffective and powerful solutions options being used for thousands of different applications around the world.
FireWire Figure 2: 1394a data transmission In case of 1394b no gaps are needed due to parallel arbitration, handled by bus owner supervisor selector (BOSS) (see the following diagram). Whereas 1394a works in half duplex transmission, 1394b does full duplex transmission.
FireWire FireWire connection capabilities FireWire can connect together up to 63 peripherals in an acyclic network structure (hubs). It allows peer-to-peer device communication (between digital cameras), to take place without using system memory or the CPU. But even more importantly, a FireWire camera can directly, via direct memory access (DMA), write into or read from the memory of the computer with almost no CPU load. FireWire also supports multiple hosts per bus.
FireWire Capabilities of 1394b (FireWire 800) FireWire 800 (S800) was introduced commercially by Apple in 2003 and has a 9-pin FireWire 800 connector (see details in Hardware Installation Guide and in Chapter IEEE 1394b port pin assignment on page 89). This newer 1394b specification allows a transfer rate of 800 MBit/s with backward compatibilities to the slower rates and 6-pin connectors of FireWire 400.
FireWire Compatibility example It’s possible to run a 1394a and a 1394b camera on the 1394b bus. You can e.g. run a STINGRAY F-033B and a MARLIN F-033B on the same bus: • STINGRAY F-033B @ S800 and 60 fps (2560 bytes per cycle, 32% of the cycle slot) • MARLIN F-033B @ S400 and 30 fps (1280 bytes, 32% of the cycle slot) Bus runs at 800 Mbit/s for all devices. Data from Marlin’s port is up-converted from 400 Mbit/s to 800 Mbit/s by data doubling (padding), still needing 32% of the cycle slot time.
FireWire Note The bandwidth values refer to the fact: 1 MByte = 1024 kByte 1394b bandwidths According to the 1394b specification on isochronous transfer, the largest recommended data payload size is 8192 bytes per 125 µs cycle at a bandwidth of 800 Mbit/s. Note Note Certain cameras may offer, depending on their settings in combination with the use of AVT FirePackage higher packet sizes. Consult your local dealer's support team, if you require additional information on this feature.
FireWire For multi-camera applications one of the following bus cards is needed: • PCI ExpressCard with potential 250 MByte/s per lane (up to 6 supported by chipset) or • 64-bit PCI-X card (160 MByte/s) Caution As mentioned earlier, it is very important not to exceed an inrush current of 18 mJoule in 3 ms. (This means that a device, when powered via 12 V bus power must never draw more than 1.5 A, even not in the first 3 ms.
FireWire Figure 5: ExpressCard technology www ExpressCard is a new standard set by PCMCIA. For more information visit: http://www.expresscard.org/web/site/ Example 1: 1394b bandwidth of Stingray cameras STINGRAY model Resolution Frame rate Bandwidth Stingray F-033 B/C 0.3 megapixel 84 fps 27.11 MByte/s Stingray F-046 B/C 0.45 megapixel 61 fps 27.60 MByte/s Stingray F-080 B/C 0.8 megapixel 31 fps 24.83 MByte/s Stingray F-125 B/C 1.25 megapixel 30 fps 36.
FireWire Example 2: More than one Stingray camera at full speed Due to the fact that one Stingray camera can, depending on its settings, saturate a 32-bit PCI bus, you are advised to use either a PCI Express card and/ or multiple 64-bit PCI bus cards, if you want to use 2 or more Stingray cameras simultaneously (see the following table).
FireWire FireWire Plug & play capabilities FireWire devices implement the ISO/IEC 13213 configuration ROM model for device configuration and identification, to provide plug & play capability. All FireWire devices are identified by an IEEE EUI-64 unique identifier (an extension of the 48-bit Ethernet MAC address format) in addition to well-known codes indicating the type of device and protocols it supports. For further details read Chapter Configuration of the camera on page 257.
FireWire Operating system support Operating system 1394a 1394b Linux Full support Full support Apple Mac OS X Full support Full support Windows XP Full support With SP2 / SP3 the default speed for 1394b is S100 (100 Mbit/s). A download and registry modification is available from Microsoft to restore performance to either S400 or S800. http://support.microsoft.
FireWire Operating system 1394a 1394b Windows Vista Full support Windows Vista incl. SP1/SP2 supports 1394b only with S400. Use either the driver of the AVT Universal Package/ AVT FirePackage or install the driver provided with the AVT 1394 Bus Driver Package. Both drivers replace the Microsoft OHCI IEEE 1394 driver, but the second is 100% compliant to the driver of Microsoft. This means, applications using the MS1394 driver will continue to work.
Filter and lenses Filter and lenses IR cut filter: spectral transmission Only Stingray color cameras have a built-in IR cut filter. The following illustration shows the spectral transmission of the IR cut filter: Figure 6: Approximate spectral transmission of IR cut filter (may vary slightly by filter lot) (type Hoya C5000) STINGRAY Technical Manual V4.4.

Camera interfaces Control data signals The inputs and outputs of the camera can be configured by software. The different modes are described below. Inputs Note For a general description of the inputs and warnings see the Hardware Installation Guide, Chapter STINGRAY input description. The optocoupler inverts all input signals. Inversion of the signal is controlled via the IO_INP_CTRL1..2 register (see Table 22: Advanced register: Input control on page 97).
Camera interfaces Input/output pin control All input and output signals running over the camera I/O connector are controlled by an advanced feature register. Register Name Field Bit Description 0xF1000300 IO_INP_CTRL1 Presence_Inq [0] Indicates presence of this feature (read only) --- [1..6] Reserved Polarity [7] 0: Signal not inverted 1: Signal inverted --- [8..10] Reserved InputMode [11..15] Mode see Table 23: Input routing on page 98 0xF1000304 IO_INP_CTRL2 --- [16..
Camera interfaces IO_INP_CTRL 1-2 The Polarity flag determines whether the input is low active (0) or high active (1). The input mode can be seen in the following table. The PinState flag is used to query the current status of the input. The PinState bit reads the inverting optocoupler status after an internal negation. See Figure 45: Input block diagram on page 96. This means that an open input sets the PinState bit to 0.
Camera interfaces Trigger delay Stingray cameras feature various ways to delay image capture based on external trigger. With IIDC V1.31 there is a standard CSR at Register F0F00534/834h to control a delay up to FFFh x time base value. The following table explains the inquiry register and the meaning of the various bits.
Camera interfaces Register Name Field Bit Description 0xF0F00834 TRIGGER_DELAY Presence_Inq [0] Presence of this feature: 0: N/A 1: Available Abs_Control [1] Absolute value control O: Control with value in the value field 1: Control with value in the absolute value CSR. If this bit=1 the value in the value field has to be ignored. --- [2..5] Reserved ON_OFF [6] Write ON or OFF this feature Read: Status of the feature ON=1 OFF=0 --- [7..19] Reserved Value [20..
Camera interfaces Note • • Switching trigger delay to ON also switches external Trigger_Mode_0 to ON. This feature works with external Trigger_Mode_0 only. Outputs Note For a general description of the outputs and warnings see the Hardware Installation Guide, Chapter STINGRAY output description. Output features are configured by software. Any signal can be placed on any output.
Camera interfaces Output mode selectable via software Polarity selectable via software Operation state read IntEna FVal Busy Opto- PulseWidthMod WaitingForTrigger Output signal Coupler Operation state read Figure 46: Output block diagram STINGRAY Technical Manual V4.4.
Camera interfaces IO_OUTP_CTRL 1-4 The outputs (Output mode, Polarity) are controlled via 4 advanced feature registers (see Table 28: Advanced register: Output control on page 103). The Polarity field determines whether the output is inverted or not. The output mode can be viewed in the table below. The current status of the output can be queried and set via the PinState. It is possible to read back the status of an output pin regardless of the output mode.
Camera interfaces Register Name Field 0xF1000328 IO_OUTP_CTRL3 Same as IO_OUTP_CTRL1 0xF100032C IO_OUTP_CTRL4 Same as IO_OUTP_CTRL1 Bit Description Table 28: Advanced register: Output control Output modes ID Mode Default / description 0x00 Off 0x01 Output state follows PinState bit Using this mode, the Polarity bit has to be set to 0 (not inverted). This is necessary for an error free display of the output status.
Camera interfaces External trigger input Delay set by Trigger_Delay register IntegrationEnable (IntEna) Delay set by IntEna_Delay register IntEna delayed FrameValid (FVal) Busy WaitingForTrigger (only edge mode) Figure 47: Output impulse diagram Note The signals can be inverted. Caution Firing a new trigger while IntEna is still active can result in missing image. STINGRAY Technical Manual V4.4.
Camera interfaces Note • • Note that trigger delay in fact delays the image capture whereas the IntEna_Delay only delays the leading edge of the IntEna output signal but does not delay the image capture. As mentioned before, it is possible to set the outputs by software. Doing so, the achievable maximum frequency is strongly dependent on individual software capabilities. As a rule of thumb, the camera itself will limit the toggle frequency to not more than 700 Hz.
Camera interfaces Period PulseWidth Figure 48: PulseWidth and Period definition Note Note the following conditions: • • PulseWidth Period Period MinPeriod PWM: minimal and maximal periods and frequencies In the following formulas you find the minimal/maximal periods and frequencies for the pulse-width modulation (PWM). period min = 3µs 1 - = ------1 - = 333.33kHz frequencymax = --------------------period min 3µs 1 frequency min = ------------------------ = 15.
Camera interfaces PWM: Examples in practice In this chapter we give you two examples, how to write values in the PWM registers. All values have to be written in microseconds (µs) in the PWM registers, therefore remember always the factor 10-6s. Example 1: Set PWM with 1kHz at 30% pulse width.
Camera interfaces Pixel data Pixel data are transmitted as isochronous data packets in accordance with the 1394 interface described in IIDC V1.31.

Description of the data path Note While lowering both U/B and V/R registers from 284 towards 0, the lower one of the two effectively controls the green gain. Figure 54: U/V slider range Type Range Range in dB Stingray color cameras 0 ... 568 10 dB Table 40: Manual gain range of the various Stingray types The increment length is ~0.0353 dB/step.
Description of the data path Note The following ancillary conditions should be observed for successful white balance: • There are no stringent or special requirements on the image content, it requires only the presence of monochrome pixels in the image. If the image capture is active (e.g. IsoEnable set in register 614h), the frames used by the camera for white balance are also output on the 1394 bus. Any previously active image capture is restarted after the completion of white balance.
Description of the data path Auto white balance can also be enabled by using an external trigger. However, if there is a pause of >10 seconds between capturing individual frames this process is aborted. Note The following ancillary conditions should be observed for successful white balance: • • There are no stringent or special requirements on the image content, it requires only the presence of equally weighted RGB pixels in the image.

Description of the data path Horizontal mirror function All Stingray cameras are equipped with an electronic mirror function, which mirrors pixels from the left side of the image to the right side and vice versa. The mirror is centered to the current FOV center and can be combined with all image manipulation functions, like binning and shading. This function is especially useful when the camera is looking at objects with the help of a mirror or in certain microscopy applications.
Description of the data path Shading correction Shading correction is used to compensate for non-homogeneities caused by lighting or optical characteristics within specified ranges. To correct a frame, a multiplier from 1...2 is calculated for each pixel in 1/256 steps: this allows for shading to be compensated by up to 50 %. Besides generating shading data off-line and downloading it to the camera, the camera allows correction data to be generated automatically in the camera itself.
Description of the data path How to store shading image There are two storing possibilities: • After generating the shading image in the camera, it can be uploaded to the host computer for nonvolatile storage purposes. • The shading image can be stored in the camera itself. The following pictures describe the process of automatic generation of correction data. Surface plots and histograms were created using the ImageJ program. 255.0 surface plot 0.0 ls xe pi 0.0 48 histogram els 0 pix 640.
Description of the data path Automatic generation of correction data Requirements Shading correction compensates for non-homogeneities by giving all pixels the same gray value as the brightest pixel. This means that only the background must be visible and the brightest pixel has a gray value of less than 255 when automatic generation of shading data is started. It may be necessary to use a neutral white reference, e.g. a piece of paper, instead of the real image.
Description of the data path Note Configuration To configure this feature in an advanced register: See Table 138: Advanced register: Shading on page 307. Note • The SHDG_CTRL register should not be queried at very short intervals. This is because each query delays the generation of the shading image. An optimal interval time is 500 ms. Note • • The calculation of shading data is always carried out at the current resolution setting.

For information on GPDATA_BUFFER: See Chapter GPDATA_BUFFER on page 340. Look-up table (LUT) and gamma function The AVT Stingray camera provides one user-defined look-up table (LUT).
Description of the data path Output = f (Input) Stingray, gamma=0.45 1000 800 t u p t u O 600 400 200 0 0 500 1000 1500 2000 2500 3000 3500 4000 Input Figure 63: LUT with gamma=0.45 Note • • • The input value is the most significant 12-bit value from the digitizer. Gamma 1 (gamma=0.45) switches on the LUT. After overriding the LUT with a user defined content, gamma functionality is no longer available until the next full initialization of the camera.
Description of the data path Loading an LUT into the camera Loading the LUT is carried out through the data exchange buffer called GPDATA_BUFFER. As this buffer can hold a maximum of 2 kB, and a complete LUT at 4096 x 10 bit is 5 kByte, programming can not take place in a one block write step because the size of an LUT is larger than GPDATA_BUFFER. Therefore input must be handled in several steps. The flow diagram below shows the sequence required to load data into the camera.
Description of the data path Defect pixel correction The mechanisms of defect pixel correction are explained in the following drawings. All examples are done in Format_7 Mode_0 (full resolution). The first two examples are explained for b/w cameras, the third example is explained for color cameras. The X marks a defect pixel. 50% brightness of pixel value 1. example 50% brightness of pixel value X b/w 50% brightness of pixel value 50% brightness of pixel value 2.
Description of the data path Building defect pixel correction image in Format_7 modes horizontal Binning/sub-sampling is always done after defect pixel correction. Defect pixel correction is always done on full horizontal resolution. Therefore defect pixel detection has always to be done in full horizontal resolution. vertical Binning/sub-sampling is done in the sensor, before defect pixel correction. Therefore defect pixel detection has to be done in the correct vertical resolution.
Description of the data path Flow diagram of defect pixel correction The following flow diagram illustrates the defect pixel detection: Set resolution to Format_7 Mode_x Or Set resolution to Format_7 Mode_0 when using fixed modes. Set AOI to max. Set values for shutter, gain to max.
Description of the data path Building defect pixel data Note • • • • • • Defect pixel detection is only possible in Mono8/ Raw8 modes. In all other modes you get an error message in advanced register 0xF1000298 bit [1] see Table 142: Advanced register: Defect pixel correction on page 312. Using Format_7 Mode_x: Defect pixel detection is done in Format_7 Mode_x. Using a fixed format (Format_0, Format_1 or Format_2): Defect pixel detection is done in Format_7 Mode_0.
Description of the data path Defect pixel coordinates are: – 16-bit y-coordinate and – 16-bit x-coordinate The calculated mean value is written in advanced register Mean field (0xF1000298 bit [18..24]). The number of defect pixels is written in advanced register DPDataSize (0xF100029C bit [4..17]). Due to 16-bit format: to get the number of defect pixels read out this value and divide through 4. For more information see Table 142: Advanced register: Defect pixel correction on page 312.
Description of the data path Note • • Switch off camera and switch on again: defect pixel data in dual port RAM will get lost Start-up camera / initialize camera: non-volatile stored defect pixel data are loaded automatically from EEPROM to dual port RAM. Send defect pixel data to the host 1. Set EnaMemRD flag to 1. Defect pixel data is transferred from dual port RAM to host. 2. Read DPDataSize. This is the current defect pixel count from the camera.

Description of the data path Binning and sub-sampling access The binning and sub-sampling modes described in the last two chapters are only available as pure binning or pure sub-sampling modes. A combination of both is not possible. As you can see there is a vast amount of possible combinations. But the number of available Format_7 modes is limited and lower than the possible combinations.

Description of the data path To optimize the transfer of parameter changes there is a new timing mode called Quick Format Change Mode, which effectively resets the current shutter.

Description of the data path Standard Update (IIDC) In the Standard Update (IIDC) mode single parameter are sent to the camera.
Description of the data path Packed 12-Bit Mode All Stingray cameras have the so-called Packed 12-Bit Mode. This means: two 12-bit pixel values are packed into 3 bytes instead of 4 bytes. B/w cameras Color cameras Packed 12-Bit MONO camera mode Packed 12-Bit RAW camera mode SmartView: MONO12 SmartView: RAW12 Mono and raw mode have the same implementation. Table 52: Packed 12-Bit Mode Note For data block packet format see Table 34: Packed 12-Bit Mode (mono and raw) Y12 format on page 114.
Description of the data path High SNR mode (High Signal Noise Ratio) Note Configuration To configure this feature in an advanced register: See Table 151: Advanced register: High Signal Noise Ratio (HSNR) on page 321. In this mode the camera grabs and averages a set number of images and outputs one image with the same bit depth and the same brightness.
Description of the data path Frame memory and deferred image transport An image is normally captured and transported in consecutive steps. The image is taken, read out from the sensor, digitized and sent over the 1394 bus. Deferred image transport As all Stingray cameras are equipped with built-in image memory, this order of events can be paused or delayed by using the deferred image transport feature. Stingray cameras are equipped with 32 MByte of RAM (Stingray F-504: 64 MByte).
Description of the data path Image transfer is controlled from the host computer by addressing individual cameras one after the other and reading out the desired number of images. Note Configuration To configure this feature in an advanced register: See Table 140: Advanced register: Deferred image transport on page 310. HoldImg mode By setting the HoldImg flag, transport of the image over the 1394 bus is stopped completely. All captured images are stored in the internal ImageFiFo.
Description of the data path The following screenshot shows the sequence of commands needed to work with deferred mode.
Description of the data path FastCapture mode Note This mode can be activated only in Format_7. By setting FastCapture to false, the maximum frame rate both for image acquisition and read out is associated with the packet size set in the BYTE_PER_PACKET register. The lower this value is, the lower the attainable frame rate is. By setting FastCapture to true, all images are recorded at the highest possible frame rate, i.e.
Description of the data path Color interpolation (BAYER demosaicing) The color sensors capture the color information via so-called primary color (R-G-B) filters placed over the individual pixels in a BAYER mosaic layout. An effective BAYER RGB color interpolation already takes place in all Stingray color version cameras. In color interpolation a red, green or blue value is determined for each pixel.
Description of the data path In color interpolation a red, green or blue value is determined for each pixel.
Description of the data path Sharpness The Stingray color models are equipped with a four-step sharpness control, applying a discreet horizontal high pass in the Y channel as shown in the next five line profiles. Sharpness 0, 1, 2, 3, 4 is calculated with the following scheme: Sharpness value Description 0 +0.25 +0.5 +0.25 Least sharp 1 +0.125 +0.75 +0.125 Less sharp 2 0 1 0 3 -0.25 +1.5 -0.25 Some sharp 4 -0.5 2 -0.
Description of the data path Note Sharpness does not show any effect on Stingray color models in the Raw8, Raw12 and Raw16 format, because color processing is switched off in all Raw formats. Note Configuration To configure this feature in feature control register: See Table 123: Feature control register on page 285. Hue and saturation Stingray CCD color models are equipped with hue and saturation registers.
Description of the data path Color correction Why color correction? The spectral response of a CCD is different of those of an output device or the human eye. This is the reason for the fact that perfect color reproduction is not possible. In each Stingray camera there is a factory setting for the color correction coefficients, see Chapter GretagMacbeth ColorChecker on page 177. Color correction is needed to eliminate the overlap in the color channels.
Description of the data path Changing color correction coefficients You can change the color-correction coefficients according to your own needs. Changes are stored in the user settings. Note • • • • • • • A number of 1000 equals a color correction coefficient of 1. To obtain an identity matrix set values of 1000 for the diagonal elements and 0 for all others. As a result you get colors like in the RAW modes. The sums of all rows should be equal to each other. If not, you get tinted images.
Description of the data path Color conversion (RGB YUV) The conversion from RGB to YUV is made using the following formulae: Y = 0.3 R + 0.59 G + 0.11 B U = – 0.169 R – 0.33 G + 0.498 B + 128 (@ 8 bit) V = 0.498 R – 0.420 G – 0.082 B + 128 (@ 8 bit) Formula 6: RGB to YUV conversion Note • • As mentioned above: Color processing can be bypassed by using so-called RAW image transfer. RGB YUV conversion can be bypassed by using RGB8 format and mode.
Description of the data path Serial interface All Stingray cameras are equipped with the SIO (serial input/output) feature as described in IIDC V1.31. This means that the Stingray’s serial interface can be used as a general RS232 interface. Data written to a specific address in the IEEE 1394 address range will be sent through the serial interface. Incoming data of the serial interface is put in a camera buffer and can be polled via simple read commands from this buffer.

Description of the data path To read data: 1. Query RDRD flag (buffer ready?) and write the number of bytes the host wants to read to RBUF_CNT. 2. Read the number of bytes pending in the receive buffer RBUF_ST (more data in the buffer than the host wanted to read?) and the number of bytes left for reading from the receive FIFO in RBUF_CNT (host wanted to read more data than were in the buffer?). 3. Read received characters from SIO_DATA_REGISTER, beginning at char 0. 4.
Controlling image capture Controlling image capture Shutter modes The cameras support the SHUTTER_MODES specified in IIDC V1.31. For all models this shutter is a global pipelined shutter; meaning that all pixels are exposed to the light at the same moment and for the same time span. Pipelined Pipelined means that the shutter for a new image can already happen, while the preceding image is transmitted.

Controlling image capture Bulk trigger (Trigger_Mode_15) Trigger_Mode_15 is an extension to the IIDC trigger modes. One external trigger event can be used to trigger a multitude of internal image intakes. This is especially useful for: • Grabbing exactly one image based on the first external trigger. • Filling the camera's internal image buffer with one external trigger without overriding images.
Controlling image capture The functionality is controlled via bit [6] and bitgroup [12-15] of the following register: Register Name Field Bit Description [0] Presence of this feature: 0: N/A 1: Available Abs_Control [1] Absolute value control O: Control with value in the Value field 1: Control with value in the Absolute value CSR If this bit = 1 the value in the Value field has to be ignored. --- [2..
Controlling image capture The screenshots below illustrate the use of Trigger_Mode_15 on a register level: • Line #1switches continuous mode off, leaving viewer in listen mode. • Line #2 prepares 830h register for external trigger and Mode_15. Left = continuous Middle = one-shot Right = multi-shot Line #3 switches camera back to continuous mode. Only one image is grabbed precisely with the first external trigger.
Controlling image capture Trigger delay As already mentioned earlier Stingray cameras feature various ways to delay image capture based on external trigger. With IIDC V1.31 there is a standard CSR at register F0F00534/834h to control a delay up to FFFh x time base value. The following table explains the Inquiry register and the meaning of the various bits.
Controlling image capture Register Name Field Bit Description 0xF0F00834 TRIGGER_DELAY Presence_Inq [0] Presence of this feature: 0: N/A 1: Available Abs_Control [1] Absolute value control O: Control with value in the Value field 1: Control with value in the Absolute value CSR If this bit = 1, the value in the Value field has to be ignored --- [2..5] Reserved ON_OFF [6] Write: ON or OFF this feature Read: read a status 0: OFF 1: ON If this bit = 0, other fields will be read only.
Controlling image capture The advanced register allows start of the integration to be delayed by max. 221 µs, which is max. 2.1 s after a trigger edge was detected. Note • Switching trigger delay to ON also switches external Trigger_Mode_0 to ON. This feature works with external Trigger_Mode_0 only. • Software trigger A software trigger is an external signal that is controlled via a status and control register: 62Ch on page 283: to activate software trigger set bit [0] to 1.
Controlling image capture To set this feature in SmartView: Trig/IO tab, Input pins table, Debounce column. Debounce time This register controls the debounce feature of the cameras input pins. The debounce time can be set for each available input separately. Increment is 500 ns Debounce time is set in Time x 500 ns Minimum debounce time is 1.
Controlling image capture Exposure time (shutter) and offset The exposure (shutter) time for continuous mode and Trigger_Mode_0 is based on the following formula: Shutter register value x time base + offset The register value is the value set in the corresponding IIDC 1.31 register (SHUTTER [81Ch]). This number is in the range between 1 and 4095. The shutter register value is multiplied by the time base register value (see Table 134: Time base ID on page 302). The default value here is set to 20 µs.
Controlling image capture Camera model Minimum exposure time Effective min. exp. time = Min. exp.
Controlling image capture Note • • • • Exposure times entered via the 81Ch register are mirrored in the extended register, but not vice versa. Longer integration times not only increase sensitivity, but may also increase some unwanted effects such as noise and pixel-to-pixel non-uniformity. Depending on the application, these effects may limit the longest usable integration time. Changes in this register have immediate effect, even when the camera is transmitting.
Controlling image capture One-shot Stingray cameras can record an image by setting the one-shot bit in the 61Ch register. This bit is automatically cleared after the image is captured. If the camera is placed in ISO_Enable mode (see Chapter ISO_Enable / freerun on page 200), this flag is ignored. If one-shot mode is combined with the external trigger, the one-shot command is used to arm it. The following screenshot shows the sequence of commands needed to put the camera into this mode.
Controlling image capture One-shot command on the bus to start of exposure The following sections describe the time response of the camera using a single frame (one-shot) command. As set out in the IIDC specification, this is a software command that causes the camera to record and transmit a single frame. The following values apply only when the camera is idle and ready for use. Full resolution must also be set.
Controlling image capture End of exposure to first packet on the bus After the exposure, the CCD sensor is read out; some data is written into the FRAME_BUFFER before being transmitted to the bus. The time from the end of exposure to the start of transport on the bus is: 710 µs ± 62.5 µs This time jitters with the cycle time of the bus (125 µs). OneShot Command Exposure Integration-Start Timebase Reg. X Shutter-Reg.
Controlling image capture Multi-shot Setting multi-shot and entering a quantity of images in Count_Number in the 61Ch register enables the camera to record a specified number of images. The number is indicated in bits 16 to 31. If the camera is put into ISO_Enable mode (see Chapter ISO_Enable / free-run on page 200), this flag is ignored and deleted automatically once all the images have been recorded.
Controlling image capture The following screenshot shows an example of broadcast commands sent with the Firedemo example of FirePackage: Figure 100: Broadcast one-shot • • Line 1 shows the broadcast command, which stops all cameras connected to the same IEEE 1394 bus. It is generated by holding the Shift key down while clicking on Write. Line 2 generates a broadcast one_shot in the same way, which forces all connected cameras to simultaneously grab one image.
Controlling image capture In this case the camera can resynchronize the horizontal clock to the new trigger event, leaving only a very short uncertainty time of the master clock period. Model Exposure start jitter (while FVal) Exposure start jitter (while camera idle) Stingray F-033 9.75 µs 1.30 µs Stingray F-046 11.59 µs 1.30 µs Stingray F-080 15.29 µs 3.33 µs Stingray F-125 13.50 µs 3.10 µs Stingray F-145 23.20 µs 5.40 µs Stingray F-146 23.20 µs 5.
Controlling image capture Sequence mode Generally all AVT Stingray cameras enable certain image settings to be modified on the fly, e.g. gain and shutter can be changed by the host computer by writing into the gain and shutter register even while the camera is running. An uncertainty of up to 3 images remains because normally the host does not know (especially with external trigger) when the next image will arrive.
Controlling image capture Note Sequence mode requires special care if changing image size, Color_Coding_ID and frame rate related parameters. This is because these changes not only affect settings in the camera but also require corresponding settings in the receiving software in the PC. Caution • • Incorrect handling may lead to image corruption or loss of subsequent images. Please ask for detailed support if you want to use this feature.

Controlling image capture SeqMode description Sequence mode Description 0x80 This mode is the default sequence mode and stepping the sequence is compatible to e.g. the Marlin series. With each image integration start the sequence is stepped one item further and the new parameter set becomes active for the next image. 0x82 Stepping of the sequence is controlled by a rising edge of an external signal. The new parameter set becomes active with the next integration start.
Controlling image capture The following flow diagram shows how to set up a sequence. Set SEQUENCE_CTRL ON_OFF flag to true (1) Set SetupMode to true (1) Set SeqLength to desired length (<=MaxLength) Set ImageNo = 0 in SEQUENCE_PARAM Assign image parameters in the corresp.

See Chapter Standard Parameter Update Timing on page 162 and Chapter New: Quick Format Change Mode (QFCM) on page 162. I/O controlled sequence stepping mode and I/O controlled sequence pointer reset via software command Both sequence modes can be controlled via software command.
Controlling image capture Figure 102: Example of sequence mode settings with AVT Firetool Instead of Firetool you also can use SmartView (Version 1.8.0 or greater), but image and transfer formats have to be unchanged (height, width, ColorID). To open the Sequence editor in SmartView: 1. Click Extras Sequence dialog Figure 103: SmartView: Extras Sequence dialog STINGRAY Technical Manual V4.4.
Controlling image capture Changing the parameters within a sequence To change the parameter set for one image, it is not necessary to modify the settings for the entire sequence. The image can simply be selected via the ImageNo field and it is then possible to change the corresponding IIDC V1.31 registers.
Controlling image capture Secure image signature (SIS): definition and scenarios Note For all customers who know SIS from Marlin cameras: • • Stingray cameras have additional SIS features: AOI, exposure/gain, input/output state, index of sequence mode and serial number. Read carefully the following chapter. SIS: Definition Secure image signature (SIS) is the synonym for data, which is inserted into an image to improve or check image integrity.
Controlling image capture • • • • • • • • • Assuming camera runs in continuous mode, the check of monotonically changing bus cycle time is a simple test that no image was skipped or lost in the camera or subsequently in the image processing chain. In (synchronized) multi-camera applications, SIS can be used to identify those images, shot at the same moment in time.
Video formats, modes and bandwidth Video formats, modes and bandwidth The different Stingray models support different video formats, modes and frame rates. These formats and modes are standardized in the IIDC (formerly DCAM) specification. Resolutions smaller than the generic sensor resolution are generated from the center of the sensor and without binning. Note • • • Note The maximum frame rates can only be achieved with shutter settings lower than 1/framerate.

Configuration of the camera Advanced feature inquiry This register indicates with a named bit if a feature is present or not. If a feature is marked as not present the associated register space might not be available and read/write errors may occur. Note Ignore unnamed bits in the following table: these bits might be set or not.

Configuration of the camera Camera status This register allows to determine the current status of the camera. The most important flag is the Idle flag. If the Idle flag is set the camera does not capture and does not send any images (but images might be present in the image FIFO). The ExSyncArmed flag indicates that the camera is set up for external triggering. Even if the camera is waiting for an external trigger event the Idle flag might get set.
Configuration of the camera Maximum resolution This register indicates the highest resolution for the sensor and is read-only. Note This register normally outputs the MAX_IMAGE_SIZE_INQ Format_7 Mode_0 value. This is the value given in the specifications tables under Picture size (max.) in Chapter Specifications on page 46ff. Register Name Field Bit Description 0xF1000200 MAX_RESOLUTION MaxWidth [0..15] Sensor width (read only) MaxHeight [16..
Configuration of the camera Note Time base can only be changed when the camera is in idle state and becomes active only after setting the shutter value. The ExpOffset field specifies the camera specific exposure time offset in microseconds (µs). This time (which should be equivalent to Table 65: Camera-specific exposure time offset on page 194) has to be added to the exposure time (set by any shutter register) to compute the real exposure time.
Configuration of the camera Extended shutter The exposure time for long-term integration of up to 67 seconds can be entered with µs precision via the EXTENDED_SHUTTER register. Register Name Field Bit Description 0xF100020C EXTD_SHUTTER Presence_Inq [0] Indicates presence of this feature (read only) --- [1..5] Reserved ExpTime [6..31] Exposure time in µs Table 135: Advanced register: Extended shutter The minimum allowed exposure time depends on the camera model.
Configuration of the camera Test images Bit [8] to [14] indicate which test images are saved. Setting bit [28] to [31] activates or deactivates existing test images. By activating any test image the following auto features are automatically disabled: • auto gain • auto shutter • auto white balance Register Name Field Bit Description 0xF1000210 TEST_IMAGE Presence_Inq [0] Indicates presence of this feature (read only) --- [1..
Configuration of the camera Look-up tables (LUT) Load the look-up tables to be used into the camera and choose the look-up table number via the LutNo field. Now you can activate the chosen LUT via the LUT_CTRL register. The LUT_INFO register indicates how many LUTs the camera can store and shows the maximum size of the individual LUTs. The possible values for LutNo are 0..n-1, whereas n can be determined by reading the field NumOfLuts of the LUT_INFO register.
Configuration of the camera Note The BitsPerValue field indicates how many bits are read from the LUT for any gray-value read from the sensor. To determine the number of bytes occupied for each grayvalue round-up the BitsPerValue field to the next byte boundary.
Configuration of the camera Shading correction Owing to technical circumstances, the interaction of recorded objects with one another, optical effects and lighting non-homogeneities may occur in the images. Because these effects are normally not desired, they should be eliminated as far as possible in subsequent image editing. The camera has automatic shading correction to do this. Provided that a shading image is present in the camera, the on/off bit can be used to enable shading correction.
Configuration of the camera Register Name Field Bit Description 0xF1000254 SHDG_MEM_CTRL Presence_Inq [0] Indicates presence of this feature (read only) --- [1..4] Reserved EnableMemWR [5] Enable write access EnableMemRD [6] Enable read access --- [7] Reserved AddrOffset [8..31] In bytes Presence_Inq [0] Indicates presence of this feature (read only) --- [1..3] Reserved MaxMemChannel [4..
Configuration of the camera 3. Poll the SHDG_CTRL register until the Busy and BuildImage flags are reset automatically. The maximum value of GrabCount depends on the camera type and the number of available image buffers. GrabCount is automatically adjusted to a power of two. Do not poll the SHDG_CTRL register too often, while automatic generation is in progress. Each poll delays the process of generating the shading image. An optimal poll interval time is 500 ms.
Configuration of the camera Deferred image transport Using this register, the sequence of recording and the transfer of the images can be paused. Setting HoldImg prevents transfer of the image. The images are stored in ImageFIFO. The images indicated by NumOfImages are sent by setting the SendImage bit. When FastCapture is set (in Format_7 only), images are recorded at the highest possible frame rate.
Configuration of the camera Frame information This register can be used to double-check the number of images received by the host computer against the number of images which were transmitted by the camera. The camera increments this counter with every FrameValid signal. This is a mirror of the frame counter information found at 0xF1000610.
Configuration of the camera Defect pixel correction Definition The defect pixel correction mode allows to correct an image with defect pixels. Via threshold you can define the defect pixels in an image. Defect pixel correction is done in the FPGA and defect pixel data can be stored inside the camera’s EEPROM. DPC = defect pixel correction WR = write RD = read MEM, Mem = memory Note • • Defect pixel correction is always done in Format_7 Mode_0.
Configuration of the camera Register Name Field Bit Description 0xF100029C DPC_MEM Presence_Inq [0] Indicates presence of this feature (read only) --- [1] Reserved EnaMemWR [2] Enable write access from host to RAM EnaMemRD [3] Enable read access from RAM to host DPDataSize [4..17] Size of defect pixel data to read from RAM to host. A maximum of 256 defect pixels can be stored. In case of more than 256 defect pixels, DPDataSize is set to 257 and BuildError flag is set to 1.
Configuration of the camera Delayed Integration Enable (IntEna) A delay time between initiating exposure on the sensor and the activation edge of the IntEna signal can be set using this register. The on/off flag activates/deactivates integration delay. The time can be set in µs in DelayTime. Note • • Only one edge is delayed. If IntEna_Out is used to control an exposure, it is possible to have a variation in brightness or to precisely time a flash.
Configuration of the camera Auto shutter control The table below illustrates the advanced register for auto shutter control. The purpose of this register is to limit the range within which auto shutter operates. Register Name 0xF1000360 AUTOSHUTTER_CTRL 0xF1000364 AUTOSHUTTER_LO Field Bit Description Presence_Inq [0] Indicates presence of this feature (read only) --- [1..31] Reserved --- [0..5] Reserved MinValue [6..
Configuration of the camera If both auto gain and auto shutter are enabled and if the shutter is at its upper boundary and gain regulation is in progress, increasing the upper auto shutter boundary has no effect on auto gain/shutter regulation as long as auto gain regulation is active. Note As with the Extended Shutter the value of MinValue and MaxValue must not be set to a lower value than the minimum shutter time.
Configuration of the camera Autofunction AOI The table below illustrates the advanced register for autofunction AOI. Register Name 0xF1000390 AUTOFNC_AOI 0xF1000394 AF_AREA_POSITION 0xF1000398 AF_AREA_SIZE Field Bit Description Presence_Inq [0] Indicates presence of this feature (read only) --- [1..3] Reserved ShowWorkArea [4] Show work area --- [5] Reserved ON_OFF [6] Enable/disable AOI (see note above) --- [7] Reserved YUNITS [8..19] Y units of work area/pos.

Configuration of the camera Secure image signature (SIS) Definition Secure image signature (SIS) is the synonym for data, which is inserted into an image to improve or check image integrity. All • • • • Stingray models can insert Cycle time (1394 bus cycle time at the beginning of integration) Frame counter (frames read out of the sensor) Trigger counter (external trigger seen only) Various camera settings into a selectable line position within the image.
Configuration of the camera Enter a • positive value from 0...HeightOfImage to specify a position relative to the top of the image. LinePos=0 specifies the very first image line. • negative value from -1...-HeightOfImage to specify a position relative to the bottom of the image. LinePos=-1 specifies the very last image line. SIS UserValue can be written into the camera’s image. In sequence mode for every sequence entry an own SIS UserValue can be written.
Configuration of the camera Examples: cycle time The following three examples allow you: • A: to access cycle time either via UniAPI or via byte array • B: to extract cycle offset, cycles and seconds • C: to combine cycle offset/cycles/seconds to a valid time Example Example code and description A nCycleTime can be accessed: • using the SIS structure S_SIS_DATA of the UniAPI: • using byte array: If you can access the image buffer as an array of bytes you can assemble the first four bytes of the image b
Configuration of the camera Advanced register: frame counter Note Different to Marlin SIS: Register 610 is only to be used to reset the frame counter.

(Here SIS has 48 bytes.
Configuration of the camera Software feature control (disable LEDs) The software feature control register allows to enable/disable some features of the camera (e.g. disable LEDs). The settings are stored permanently within the camera and do not depend on any user set. Register Name 0xF1000640 SWFEATURE_CTRL Field Bit Description Presence_Inq [0] Indicates presence of this feature (read only) BlankLED_Inq [1] Indicates presence of Disable LEDs feature. --- [2..
Configuration of the camera User profiles Definition Within the IIDC specification user profiles are called memory channels. Often they are called user sets. In fact these are different expressions for the following: storing camera settings into a non-volatile memory inside the camera.
Configuration of the camera Store Restore Set default To store the current camera settings into a profile: 1. Write the desired ProfileID with the SaveProfile flag set. 2. Read back the register and check the ErrorCode field. To restore the settings from a previous stored profile: 1. Write the desired ProfileID with the RestoreProfile flag set. 2. Read back the register and check the ErrorCode field. To set the default profile to be loaded on startup, reset or initialization: 1.
Configuration of the camera Reset of error codes The ErrorCode field is set to zero on the next write access. You may also reset the ErrorCode • by writing to the USER_PROFILE register with the SaveProfile, RestoreProfile and SetDefaultID flag not set. • by writing 00000000h to the USER_PROFILE register.
Configuration of the camera Note • • • • • A profile save operation automatically disables capturing of images. A profile save or restore operation is an uninterruptable (atomic) operation. The write response (of the asynchronous write cycle) will be sent after completion of the operation. Restoring a profile will not overwrite other settings than listed above.
Configuration of the camera GPDATA_BUFFER GPDATA_BUFFER is a general purpose register that regulates the exchange of data between camera and host for: • writing look-up tables (LUTs) into the camera • uploading/downloading of the shading image GPDATA_INFO GPDATA_BUFFER Register Buffer size query indicates the actual storage range Name 0xF1000FFC GPDATA_INFO 0xF1001000 Field Bit Description --- [0..15] Reserved BufferSize [16..
