Camera interfaces Control and video 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 1394 Installation Manual. Triggers The signal can be inverted. The camera must be set to external triggering to trigger image capture by the trigger signal.
PAGE 63
Camera interfaces Note  Make sure that output and input are not enabled at the same time. In order to use a pin as an input (e.g. for external trigger), its output driver (e.g. IntEna) needs to be switched off. IO_INP_CTRL 1 The Polarity field determines whether the input is inverted (0) or not (1). See Table 18: Input configuration register on page 62. The InputMode field can be seen in the following table. The PinState field is used to query the current status of the input.

Camera interfaces IO_OUTP_CTRL 1-3 The outputs are controlled via 3 advanced feature registers (see Table 24: Advanced register: Output control on page 68). The Polarity field determines whether the output is inverted (1) or not (0). 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 Note The signals can be inverted.  Caution  Note Firing a new trigger while IntEna is still active can result in missing image. •  • 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.

Description of the data path As mentioned before two adjacent pixels in a line are used to calculate a luma (Y) value and one component (R-Y or B-Y) of the chroma values. This means: a half sized color image per field is reconstructed. After deinterlacing the image has the properties of a 4:2:2 image. Format_7 Mode_1: sensor readout and color In Format_7 Mode_1 controlling gain is done digitally for each of the four channels Cyan, Yellow, Magenta and Green.

Description of the data path White balance and interlaced Guppys For the interlaced Guppys (Guppy F-038/038 NIR/044/044 NIR) there is a nonstandard (non-IIDC) register for white balance (0xF10080C4 and 0xF10080C8). This register is similar to the standard white balance CSR: here each of the four colors can be controlled independently. One-push white balance is not available. Format_7 Mode_0: the binned 4 pixels have separate gains.
PAGE 95
Description of the data path One-push white balance Note  Interlaced Guppys (Guppy F-038/038 NIR/044/044 NIR) do not have one-push white balance. Note Configuration  To configure this feature in control and status register (CSR): See Table 100: Feature control register on page 222. The camera automatically generates frames, based on the current settings of all registers (GAIN, OFFSET, SHUTTER, etc.).

Description of the data path The following flow diagram illustrates the one-push white balance sequence. Pause image capture Capture image via one-shot Repeat steps nine times Calculate and set correction values Restart image capture if necessary Figure 59: One-push white balance sequence Finally, the calculated correction values can be read from the WHITE_BALANCE register 80Ch.

Description of the data path Auto gain In combination with auto white balance, all Guppy CCD and CMOS models are equipped with auto gain feature. When enabled auto gain adjusts the gain within the default gain limits or within the limits set in advanced register F1000370h in order to reach the brightness set in auto exposure register as reference. Increasing the auto exposure value (aka target grey value) increases the average brightness in the image and vice versa.

Description of the data path Look-up table (LUT) and gamma function The Guppy camera provides one user-defined look-up table (LUT). The use of this LUT allows any function (in the form Output = F(Input)) to be stored in the camera's RAM and applied to the individual pixels of an image at run-time. The address lines of the RAM are connected to the incoming digital data, these in turn point to the values of functions which are calculated offline, e.g. with a spreadsheet program.
PAGE 107
Description of the data path Note •  • • • • • The input value is the 10-bit value from the digitizer. The gamma LUT of the CCD models outputs the most significant 8 bit as shown above. As gamma correction for the CCD models is also implemented via the look-up table, it is not possible to use a different LUT when gamma correction is enabled. With all CCD models, the user LUT will be overridden when gamma is enabled.

Description of the data path DPC data are organized like this: 31 16 15 y-coordinate x-coordinate 0 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 115: Advanced register: Defect pixel correction on page 243.

No color interpolation Guppy color cameras have no color interpolation, so the BAYER demosaicing has to be done outside the camera in the PC (raw mode).

Controlling image capture Controlling image capture Global shutter (CCD cameras only) Shutter modes The cameras support the SHUTTER_MODES specified in IIDC V1.3. For all Guppy models (except Guppy F-036/503) this shutter is a global shutter; meaning that all pixels are exposed to the light at the same moment and for the same time span. Continuous mode In continuous modes the shutter is opened shortly before the vertical reset happens, thus acting in a frame-synchronous way.

Controlling image capture Trigger_Mode_15 (bulk trigger) Note Trigger_Mode_15 is only available for Guppy CCD cameras.  Trigger_Mode_15 is a bulk trigger, combining one external trigger event with continuous or one-shot or multi-shot internal trigger. It 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.

Controlling image capture Trigger delay As already mentioned earlier, the 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 timebase value. The following table explains the inquiry register and the meaning of the various bits.

PAGE 155
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 timebase + offset The register value is the value set in the corresponding IIDC 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 110: Time base ID on page 237). The default value here is set to 20 μs.
PAGE 156
Controlling image capture Minimum shutter time of Guppy F-036 Note The minimum shutter time (without offset) is 179 μs.  Example Guppy F-036 Set Shutter register: 100 100 x 20 μs = 2000 μs 2000 μs/29.89 μs = 66.91 Effective shutter: 66 x 29.89 μs = 1972.74 μs (without offset) Example Guppy F-503 Set Shutter register: 100 100 x 20 μs = 2000 μs 2000 μs/41.8 μs = 47.85 Effective shutter: 47 x 41.8 μs = 1964.6 μs (without offset) Exposure time offset A camera-specific offset is also added to this value.

Extended shutter The exposure time for long-term integration of: • up to 67 seconds for the CCD models • up to 979 ms for the Guppy F-036 (CMOS model) • up to 2.
PAGE 158
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 ISO_Enable / free-run Setting the MSB (bit 0) in the 614h register (ISO_ENA) puts the camera into ISO_Enable mode or Continuous_Shot. The camera captures an infinite series of images. This operation can be quit by deleting the 0 bit. Asynchronous broadcast The camera accepts asynchronous broadcasts. This involves asynchronous write requests that use node number 63 as the target node with no acknowledge.

Video formats, modes and bandwidth Area of interest (AOI) The camera’s image sensor has a defined resolution. This indicates the maximum number of lines and pixels per line that the recorded image may have. However, often only a certain section of the entire image is of interest. The amount of data to be transferred can be decreased by limiting the image to a section when reading it out from the camera. At a lower vertical resolution the sensor can be read out faster and thus the frame rate is increased.
PAGE 175
Video formats, modes and bandwidth Note  For more information see Table 102: Format_7 control and status register on page 226. Figure 98: Area of interest (AOI) Note •  • The left position + width and the upper position + height may not exceed the maximum resolution of the sensor. The coordinates for width and height must be divisible by 4. The minimum AOI of the Guppy F036 is limited to 92 x 60 pixels.

Use this feature to select the image area (work area) on which the following autofunctions work: • Auto shutter • Auto gain • Auto white balance Note  Auto gain of CMOS models is directly controlled by the CMOS sensor (the target grey level is fixed to 125). Autofunction AOI does not work with auto gain.
PAGE 177
Video formats, modes and bandwidth Note Autofunction AOI is independent from Format_7 AOI settings.  If you switch off autofunction AOI, work area position and work area size follow the current active image size. To switch off autofunctions, carry out following actions in the order shown: 1. Uncheck Show AOI check box (SmartView Ctrl2 tab). 2. Uncheck Enable check box (SmartView Ctrl2 tab). Switch off Auto modi (e.g. Shutter and/or Gain) (SmartView Ctrl2 tab).

How does bandwidth affect the frame rate? How does bandwidth affect the frame rate? In some modes the IEEE 1394a bus limits the attainable frame rate. According to the 1394a specification on isochronous transfer, the largest data payload size of 4096 bytes per 125 μs cycle is possible with bandwidth of 400 Mbit/s. In addition, there is a limitation, only a maximum number of 65535 (216 -1) packets per frame are allowed (Guppy F-036: max. number of 800 packets due to the sensor limitation).

The possible values for LutNo are 0..n-1, whereas n can be determined by reading the field NumOfLuts of the LUT_INFO register.
PAGE 241
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 gray-value round-up the BitsPerValue field to the next byte boundary. Examples: • BitsPerValue = 8  1 byte per gray-value • BitsPerValue = 14  2 byte per gray-value Divide MaxLutSize by the number of bytes per gray-value in order to get the number of bits read from the sensor.

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 (only Guppy F-503) 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 MinValue and MaxValue limits the range the auto shutter feature is allowed to use for the regulation process. Both values are initialized with the minimum and maximum value defined in the standard SHUTTER_INQ register (multiplied by the current active timebase). If you change the MinValue and/or MaxValue and the new range exceeds the range defined by the SHUTTER_INQ register, the standard SHUTTER register will not show correct shutter values.

Configuration of the camera MinValue and MaxValue limits the range the auto gain feature is allowed to use for the regulation process. Both values are initialized with the minimum and maximum value defined in the standard GAIN_INQ register. Changing the auto gain range might not affect the regulation, if the regulation is in a stable condition and no other condition affecting the image brightness is changed.
