  • Page 35: Averaging Horizontal Pixels

    Piranha Color Camera The Piranha Color is a bi-directional camera and the direction of the web movement can be arranged in either way. If the object is passing the camera in the other direction, its image will pass over the Blue channel first, then the Green channel, and finally the Red channel.

  • Page 36: Processing Chain Overview And Description

    Piranha Color Camera Notes:  Selecting sah 1 results in no averaging.  Selecting sah 2 averages pairs of pixels: (P1+P2)/2, (P3+P4)/2, (P5+P6)/2…  If you are using averaging, the minimum, maximum, and mean statistics generated by the gl or gla commands and used by the ccg, cao, ccf, and ccp commands are for the un-averaged pixels.

  • Page 37: Digital Processing

    Piranha Color Camera Analog Processing  Optimizing offset performance and gain in the analog domain allows you to achieve a better signal-to-noise ratio and dynamic range use. Perform all analog adjustments prior to any digital adjustments.  Analog gain ( command) is multiplied by the analog signal to increase the signal strength before the A/D conversion (and before noise is added to the signal).

  • Page 38: Analog Gain And Analog Offset

    Piranha Color Camera  CCF: calibrate FPN  CCP: calibrate PRNU  CPA: calibrate analog gain (SAG) and PRNU PRNU calibration includes the FPN whether it is enabled or not (as they are linked). If you do not want the PRNU calibration to include the effect of FPN then it should be zeroed first using the RPC command.

Electrostatic charge introduced to the sensor window surface can induce charge buildup on the underside of the window that cannot be readily dissipated by the dry nitrogen gas in the sensor package cavity.

    Piranha Color Camera Scratches diffract incident illumination. When exposed to uniform illumination, a sensor with a scratched window will normally have brighter pixels adjacent to darker pixels. The location of these pixels changes with the angle of illumination. 5.3 Cleaning the Sensor Window Use compressed air to blow off loose particles.
