    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.

  • Page 55: Oscar F-510C: Icx-282Aq Readout Scheme

    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 resolu- tion.

  • Page 56: Oscar F-810C: Icx-456Aq Readout Scheme

    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.

  • Page 57: Frame Readout Implications

    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.

  • Page 59: White Balance

    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 non- colored. 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.
  • Page 60 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 Description 0xF0F0080C WHITE_BALANCE Presence_Inq [0] Presence of this feature: 0: N/A;...

To activate one-push automatic white balance: Set one-push bit in the WHITE_BALANCE register.
  • Page 62 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.

  • Page 63: Automatic White Balance

    Description of the data path Automatic white balance The auto white balance feature continuously optimizes the color characteris- tics 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 To set position and size of the control area...

  • Page 64: Manual Gain

    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 pix- els 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 page 52).

  • Page 65: Auto Gain

    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.

  • Page 71: Look-Up Table (Lut) And Gamma Function

    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.
  • Page 72 Description of the data path Note • 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.

  • Page 73: Loading An Lut Into 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 com- plete 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.

  • Page 74: Shading Correction

    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 cam- era itself.

  • Page 75: Automatic Generation Of Correction Data

    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 back- ground must be visible and the brightest pixel has a gray value of less than 255 when automatic generation of shading data is started.
  • Page 76 Description of the data path Note Configuration 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.
  • Page 77 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 V2.4.0...
  • Page 78 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.

  • Page 81: Loading A Shading Image Out Of The Camera

    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. Due to the size of a shading image being larger than GPDATA_BUFFER, output must be handled in several steps: Query limits from register: SHDG_INFO and...

  • Page 82: Loading A Shading Image Into 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.

  • Page 83: Horizontal Mirror Function

    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.

    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. Binning is used primarily for 3 reasons: •...

  • Page 85: Vertical Binning

    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 sep- aration by about 3 dB.

  • Page 86: Horizontal 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.

  • Page 87: X Full Binning

    Description of the data path 2 x full binning If horizontal and vertical binning are combined, every 4 pixels are consoli- dated 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.

  • Page 88: Sub-Sampling

    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.

    Description of the data path RAW mode is accessible via Color_Mode Mono8, RAW8 and via Format_7. Note 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.

  • Page 92: Color Correction

    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.

  • Page 95: Serial Interface

    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.

  • Page 100: Controlling Image Capture

    Controlling image capture Controlling image capture Shutter modes The cameras support the SHUTTER_MODES specified in IIDC V1.3. For all mod- els 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.

  • Page 107 Controlling image capture The advanced register allows the start of the integration to be delayed by max. 2 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.

  • Page 108: Shutter Modes

    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.
  • Page 109 Controlling image capture Note • 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.

  • Page 110: Joint Shutter

    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.

  • Page 111: Exposure Time (Shutter) And Offset

    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]).

  • Page 193: Autofunction Aoi

    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 regu- lation is in a stable condition and no other condition affecting the image brightness is changed.
  • Page 194 Configuration of the camera Due to the fact that the active image size might not be divisible by 128 with- out 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.
