Camera dimensions Adjustment of C-Mount Oscar cameras allow the precise adjustment of the back focus of the C-Mount by means of a back focus ring which is threaded into the C-Mount and held by two screws on either side of the camera. The mechanical adjustment of the imaging device is important in order to achieve a perfect alignment with the focal point of the lens. This adjustment is made before leaving the factory to conform to the standard of 17.

Camera interfaces Trigger delay Oscar cameras feature various ways to delay image capture based on an 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.

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.
Camera interfaces Pixel data Pixel data are transmitted as isochronous data packets in accordance with the 1394 interface described in IIDC V1.3. The first packet of a frame is identified by the 1 in the sync bit (sy) of the packet header. sync bit 0-7 8-15 data_length 16-23 tg channel 24-31 tCode sy header_CRC Video data payload data_CRC Table 19: Isochronous data block packet format.

Description of the data path Description of the data path Block diagram of the cameras The following diagram illustrates the data flow and the bit resolution of image data after being read from the CCD sensor chip in the camera. The individual blocks are described in more detail in the following paragraphs. For sensor data see Chapter Specifications on page 21.
Description of the data path Black and white output interpolation modes Various black and white output interpolation modes have been implemented in the data path to ensure high quality black and white image output. The cameras are able to output: • B/w signal out of luma interpolation formula (Y = 0.3R + 0.6G + 0.
Description of the data path Oscar F-320C: ICX-262AQ readout scheme The screenshot below, taken from the Oscar F-320C sensor's data sheet, shows the ICX-262AQ readout scheme. Frame readout mode reads out red and green color pixels in the first field, followed by the green and blue pixels in the second field. Note L The high frame readout mode reads out 2 from 12 lines and thus achieves a remarkably high frame rate of nearly 40 fps. Figure 21: Oscar F-320C: Sony ICX-262AQ readout scheme Note L 1.
Description of the data path 2. High frame rate readout mode Output is performed at 30 frames per second by reading out 2 pixels for every 12 vertical pixels. The number of output lines is 258 lines. This readout mode emphasizes processing speed over vertical resolution. Oscar F-510C: ICX-282AQ readout scheme Oscar F-510C is equipped with the ICX-282AQ sensor. Frame readout is again two fields and has the two primary colors, red and blue, read out in separate fields.
Description of the data path Oscar F-810C: ICX-456AQ readout scheme Oscar F-810C uses the ICX-456AQ sensor with three field readout mode. Every field skips two lines during read out, so all primary colors of the BAYER mosaic are read out in every field. Progressive scan mode reads out 2 out of 6 lines. Figure 23: Oscar F-810C: Sony ICX-456AQ readout scheme OSCAR Technical Manual V2.4.
Description of the data path Frame readout implications Frame readout has implications when shooting moving or stationary objects. To compensate for this condition, two different shutter modes have been introduced. The so-called split shutter opens and closes the shutter per field. This mode is suitable for shooting stationary objects only.
Description of the data path Exposure (Flash) Shutter first field Output first field to camera buffer Shutter second field Output second field to camera buffer Figure 25: Joint shutter The following pre-requisites are necessary to handle moving image acquisition in joint shutter mode: • Strobe light and • Ambient light reduced by proper light shields or • Mechanical external shutter • LCD optical shutter Note L Consult the factory or your local dealer if you have special applications requiring extern
Description of the data path White balance Oscar cameras have both manual and automatic white balance. White balance is applied so that non-colored image parts are displayed noncolored. White balance does not use the so called PxGA® (Pixel Gain Amplifier) of the analog front end (AFE) but a digital representation in the FPGA in order to modify the gain of the two channels with lower output by +9.5 dB (in 512 steps) relative to the channel with highest output.
Description of the data path From the user's point of view, the white balance settings are made in register 80Ch of IIDC V1.3. This register is described in more detail below. Register Name Field Bit 0xF0F0080C WHITE_BALANCE Presence_Inq [0] Description 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 will be ignored. --- [2..
Description of the data path Figure 27: U/V slider range One-push automatic white balance Note Configuration L To configure this feature in control and status register (CSR): See Chapter White balance register on page 60. To activate one-push automatic white balance: Set one-push bit in the WHITE_BALANCE register. The camera automatically generates frames, based on the current settings of all registers (GAIN, OFFSET, SHUTTER, etc.).
Description of the data path 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. Automatic 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.
Description of the data path Automatic white balance The auto white balance feature continuously optimizes the color characteristics of the image. As a reference, it uses a grid of at least 300 samples equally spread over the area of interest or a fraction of it. Note Configuration L To set position and size of the control area (Auto_Function_AOI) in an advanced register: see Table 95: Advanced register: Autofunction AOI on page 193.
Description of the data path The algorithm bases on the assumption that the R-G-B component sums of the samples are equal, i.e., it assumes that the mean of the sampled grid pixels is to be monochrome. Visualization of the AUTOFNC_AOI is carried out with the help of the graphics overlay function of the camera (see Chapter Block diagram of the cameras on page 52). This area is highlighted when the Show work area bit is set high.
Description of the data path Auto gain In combination with auto white balance, all Oscar cameras 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 Register Name Field Bit Description 0xF0F00804 AUTO_EXPOSURE 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..
Description of the data path Note • L • • Values can only be changed within the limits of gain CSR. Changes in auto exposure register only have an effect when auto gain is active. Auto exposure limits are 50..205. (SmartView Ctrl1 tab: Target grey level) Brightness (black level or offset) It is possible to set the black level in the camera within the following ranges: 0...
Description of the data path The IIDC brightness register at offset 800h is used for this purpose. The following table shows the BRIGHTNESS register. Register Name Field Bit Description 0xF0F00800 BRIGHTNESS 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..
Description of the data path Auto shutter In combination with auto white balance, Oscar cameras are equipped with an auto shutter feature. When enabled, the auto shutter adjusts the shutter within the default shutter limits or within those set in advanced register F1000360h in order to reach the reference brightness set in auto exposure register. Note L Target grey level parameter in SmartView corresponds to Auto_exposure register 0xF0F00804 (IIDC).
Description of the data path To configure this feature in control and status register (CSR): Register Name Field Bit Description 0xF0F0081C SHUTTER 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..
Description of the data path Look-up table (LUT) and gamma function The AVT Oscar 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 to be applied on 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.
Description of the data path Note • L • • • The input value is the most significant 12-bit value from the digitizer. The gamma LUT outputs the most significant 8 bit as shown above. As gamma correction is also implemented via the LUT, it is not possible to use a different LUT when gamma correction is enabled. 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 kByte, and a complete LUT at 4026 x 8 bit is 4 kByte, programming can’t 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 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 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 L To configure this feature in an advanced register: See Table 90: Advanced register: Shading on page 188. 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. L Note • The maximum value of GRAB_COUNT depends on the type of camera and the number of frame buffers that exist.
Description of the data path Figure 34: Generation of shading image After the lens has been focused again, the image below will be seen, but now with a considerably more uniform gradient. This is also made apparent in the graph on the right. OSCAR Technical Manual V2.4.
Description of the data path Figure 35: Example of shaded image The shading reference image can be output for permanent storage purposes on a host system. It can be further uploaded into the camera, so that the shading procedure must not be repeated after power down of the camera. OSCAR Technical Manual V2.4.
Description of the data path What is the real size of the shading image (MaxImageSize)? The register 0xF1000258 SHDG_INFO (MaxImageSize) delivers the sensor size but not the size of the shading image buffer. Therefore: If you use this reported (but wrong) MaxImageSize then: • A shading image which is too small will be uploaded/downloaded. • The shading correction will only be applied on the first field.
Description of the data path Camera model N: number of fields per frame BufferSize Oscar F-320C 2 620000h Oscar F-510C 2 A00000h Oscar F-810C 3 FC0000h Table 27: Number of fields and BufferSize For uploading/downloading a shading image the last Gap n can be ignored. The size of a field is calculated from the MaxImageSize which is theoretically camera dependent (MaxImageSize < BufferSize).
Description of the data path Loading a shading image out of the camera GPDATA_BUFFER is used to load a shading image out of the camera.
Description of the data path Loading a shading image into the camera GPDATA_BUFFER is used to load a shading image into the camera. Because the size of a shading image is larger than GPDATA_BUFFER, input must be handled in several steps: It is recommended that block writes are used to write a block of n bytes with one command into the GPDATA_BUFFER. With firmware 3.04 it is possible to write quadlets directly into the buffer, but this takes much more time.
Description of the data path Horizontal mirror function All Oscar 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, shading and DSNU. 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 Binning (only Oscar F-510C) 2 x Binning Definition Binning is the process of combining neighboring pixels while being read out from the CCD chip. Note Only Oscar F-510C has the binning feature.
Description of the data path Vertical binning Vertical binning increases the light sensitivity of the camera by a factor of two by adding together the values of two adjoining vertical pixels output as a single pixel. At the same time this normally improves signal-to-noise separation by about 3 dB. This reduces vertical resolution. The new resolution is approximately 1/2 of the original resolution. Format_7 Mode_6 By default use Format_7 Mode_6 for 2 x vertical binning.
Description of the data path Horizontal binning Definition In horizontal binning adjacent horizontal pixels in a line are combined in pairs. This means that in horizontal binning the light sensitivity of the camera is also increased by a factor of two (6 dB). Signal-to-noise separation improves by approx. 3 dB. This reduces horizontal resolution. The new resolution is approximately 1/2 of the original resolution. Format_7 Mode_5 By default use Format_7 Mode_5 for 2 x horizontal binning.
Description of the data path 2 x full binning If horizontal and vertical binning are combined, every 4 pixels are consolidated into a single pixel. At first two horizontal pixels are put together and then combined vertically. Light sensitivity This increases light sensitivity by a total of a factor of 4 and at the same time signal-to-noise separation is improved by about 6 dB. Resolution This reduces horizontal and vertical resolution. The new resolution is approximately 1/4 of the original resolution.
Description of the data path Sub-sampling What is sub-sampling? Definition Sub-sampling is the process of skipping neighboring pixels (with the same color) while being read out from the CCD chip. Which Oscar models have sub-sampling? All Oscar models have this feature.
Description of the data path 2 out of 4 H+V sub-sampling Figure 42: 2 out of 4 H+V sub-sampling (color) Note L Changing sub-sampling modes involves the generation of new shading reference images due to a change in the image size. High SNR mode (High Signal Noise Ratio) To configure this feature in an advanced register: See Table 101: Advanced register: High Signal Noise Ratio (HSNR) on page 197.
Description of the data path Sharpness All Oscar models are equipped with a two-step sharpness control, applying a discreet horizontal high pass in the green channel as shown in the next three line profiles. Figure 43: Sharpness: left: 0, middle: 1, right: 2 Note Configuration L To configure this feature in feature control register: See Table 77: Feature control register on page 169.
Description of the data path RAW mode is accessible via Color_Mode Mono8, RAW8 and via Format_7. Note L If the PC does not perform BAYER to RGB post-processing the b/w image will be superimposed with a checkerboard pattern. Color interpolation (BAYER demosaicing) In color interpolation, a red, green or blue value is determined for each pixel.
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 Oscar camera there is a factory setting for the color correction coefficients, see Chapter GretagMacbeth ColorChecker on page 92. Color correction is needed to eliminate the overlap in the color channels.
Description of the data path Color correction can also be switched off in YUV mode with the help of the following register: Register Name Description 0xF10003A0 COLOR_CORR Write: 02000000h to switch color correction OFF Write: 00000000h to switch color correction ON (default) Table 28: Color correction switch off in YUV mode 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.
Description of the data path This means a setting of zero changes the image to black and white and a setting of 511 doubles the color intensity compared to the nominal one at 256. Note Configuration L To configure this feature in feature control register: See Table 77: Feature control register on page 169. Consider hue changes as a change in the angle of the vector, saturation a change in the length of the vector S, and all starting from the intensity coordinate (vector from black to white).
Description of the data path Serial interface All Oscar cameras are equipped with the SIO (serial input/output) feature as described in IIDC V1.31. This means that the Oscar's serial interface which is used for firmware upgrades can also 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 serial interface data is put into a camera buffer and can be polled from here via simple read commands.

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 (more data the host wanted to read 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 V1.3. For all models this shutter is a global (field) shutter; meaning that all pixels (in the same field) 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 Level mode (Trigger_Mode_1) Trigger_Mode_1 sets the shutter time in the progressive modes according to the active low time of the pulse applied (or active high time in the case of an inverting input). External Trigger input, as applied at input pin, trigger falling edge External Trigger input, after inverting opto coupler Shutter register value External Trigger input, as applied at input pin External Trigger input, after inv. Opto.
Controlling image capture Bulk trigger (Trigger_Mode_15) 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 of 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 The functionality is controlled via bit [6] and bitgroup [12-15] of the IIDC 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: • The first line switches continuous mode off, leaving viewer in listen mode. • The second line 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, 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 time base value. The following table explains the inquiry register and the meaning of the various bits.
Controlling image capture Name 0xF0F00834 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..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. --- [7..19] Reserved Value [20..
Controlling image capture The advanced register allows the start of the integration to be delayed by max. 221 µs, which is max. 2.1 s after a trigger edge was detected. Note • L • Switching trigger delay to ON also switches external Trigger_Mode_0 to ON. This feature works with external Trigger_Mode_0 only. OSCAR Technical Manual V2.4.
Controlling image capture Shutter modes Due to the frame readout (interlaced) modes of the sensors, two different shutter modes exist for the maximum resolution formats accessible via the mode register in Format_7. The conversion from interlaced to progressive takes place in the camera's internal memory. Split shutter The split shutter term results from the fact that two (Oscar F-810C: three) fields are exposed and read out of the sensor one after the other.
Controlling image capture Note • L • Combining split shutter with one-shot operation, it can also be seen from the above figure that the frame rate in one-shot mode is lower than that in continuous mode. This is a result of the additional delay of one or two (Oscar F-810C) fields before the progressive output of the camera can start. Using split shutter with a flash device connected to IntEna, you will notice that it flashes twice (or three) times per single image capture. OSCAR Technical Manual V2.4.
Controlling image capture Joint shutter Use Format_7 Mode_0 when a strobe light flashes moving objects. The exposure for the two (three: F-810C) fields starts concurrently so that the strobe freezes odd and even lines at the same time. Field one is read out first, field two (and three) are read out after field one. Make sure that the ambient light can be neglected, otherwise it will contribute to the illumination of the scene and introduce image oddities. The following diagram illustrates this mode.
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 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 85: Advanced register: Time base on page 184).
Controlling image capture Extended shutter The exposure time for long-term integration of up to 67 seconds can be extended via the advanced register: EXTENDED_SHUTTER 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 38: Advanced register: extended shutter The longest exposure time, 3FFFFFFh, corresponds to 67.11 sec.
Controlling image capture One-shot Oscar 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 / free-run on page 115), 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 Microcontroller sync is an internal signal. It is generated by the microcontroller to initiate a trigger. This can either be a direct trigger or a release for ExSync, if the camera is externally triggered. 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: 500 µs ± 62.
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 115), 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 (version 1V51 or newer): Figure 53: 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 Camera idle Camera busy Oscar F-320C ± 3.35 µs ± 98 µs Oscar F-510C ± 6.00 µs ± 134 µs Oscar F-810C ± 7.85 µs ± 128 µs Table 40: Jitter at exposure start Note L • Jitter at the beginning of an exposure has no effect on the length of exposure, i.e. it is always constant.
Controlling image capture Image transfer is controlled from the host computer by addressing individual cameras and reading out the desired number of images. Functionality is controlled by the following register: Register Name Field Bit Description 0xF1000260 DEFERRED_TRANS Presence_Inq [0] Indicates presence of this feature (read only) --- [1..

Video formats, modes and bandwidth Video formats, modes and bandwidth The different Oscar models support different video formats, modes and frame rates. These formats and modes are standardized in the IIDC (formerly DCAM) specification. Resolutions in Format_0, Format_1 and Format_2, which are smaller than the generic sensor resolution, are generated symmetrically from the center of the sensor and without binning.

Video formats, modes and bandwidth Area of interest (AOI) 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. Note The setting of AOIs is supported only in video Format_7.
Video formats, modes and bandwidth Figure 55: Area of Interest (AOI) Note • L • The left position + width and the upper position + height may not exceed the maximum resolution of the sensor. The increments may vary from model and mode. The coordinates for width and height must be divisible by a factor which is depending on the camera model. The following table lists the various increments in pixel (px) as a function of the camera model and mode.
Video formats, modes and bandwidth In addition to the Area of Interest, some other parameters have an effect on the maximum frame rate: • The time for reading the image from the sensor and transporting it into the FRAME_BUFFER • The time for transferring the image over the FireWire™ bus • The length of the exposure time. Read the next chapter for more details. Frame rates An IEEE 1394 camera requires bandwidth to transport images.

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, because of a limitation in an IEEE 1394 module (GP2Lynx), only a maximum number of 4095 packets per frame are allowed.

Configuration of the camera Time base Corresponding to IIDC, exposure time is set via a 12-bit value in the corresponding register (SHUTTER_INQ [51Ch] and SHUTTER [81Ch]). This means that you can enter a value in the range of 1 to 4095. Oscar cameras use a time base which is multiplied by the shutter register value. This multiplier is configured as the time base via the TIMEBASE register.
Configuration of the camera ID Time base in µs 8 500 9 1000 Description Table 86: Time base ID Note L The ABSOLUTE VALUE CSR register, introduced in IIDC V1.3, is not implemented. 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.

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. 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 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 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 processing. 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 0xF1000258 SHDG_INFO Presence_Inq [0] Indicates presence of this feature (read only) --- [1..7] Reserved MaxImageSize [8..31] Maximum shading image size (in bytes) Table 90: Advanced register: Shading OSCAR Technical Manual V2.4.
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 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 • • L 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 Field Bit Description Presence_Inq [0] Indicates presence of this feature (read only) --- [1..31] Reserved 0xF1000364 AUTOSHUTTER_LO Min Value [0..31] Minimum value 0xF1000368 AUTOSHUTTER_HI Max Value [0..
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.
Configuration of the camera Due to the fact that the active image size might not be divisible by 128 without a remainder, the auto function AOI work area size might be greater. This allows for the positioning of the work area to be at the bottom of the active image. E.g. if the active image size is 640 x 480 pixel the camera accepts a maximum of 640 x 512 pixel as the auto function AOI work area (if the control area position is 0:0).
Configuration of the camera Color correction To switch off color correction in YUV mode: see bit [6] Register Name 0xF10003A0 COLOR_CORR Field Bit Description ON_OFF [6] Color correction on/off default: on Write: 02000000h to switch color correction OFF Write: 00000000h to switch color correction ON Table 97: Advanced register: Color correction Trigger delay Register Name 0xF1000400 TRIGGER_DELAY Field Bit Description Presence_Inq [0] Indicates presence of this feature (read only) --- [

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. From firmware 3.04 onwards, Oscar cameras can store up to three user profiles (plus the factory default) in the camera in a non-volatile memory.
Configuration of the camera Store Restore Set default Factory 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 Advanced registers TIMEBASE EXTD_SHUTTER IO_INP_CTRL IO_OUTP_CTRL IO_INTENA_DELAY AUTOSHUTTER_LO AUTOSHUTTER_HI AUTOGAIN_CTRL AUTOFNC_AOI COLOR_CORR TRIGGER_DELAY MIRROR_IMAGE HIGH_SNR LUT_CTRL LUT_DATA Table 104: User profile: stored settings The user can specify which one will be loaded upon startup of the camera. This frees the user software from having to restore camera settings, that differ from default, after every startup.
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 Field Bit Description --- [0..15] Reserved BufferSize [16..
