    8.Features 8.4. Image Processing 8.4.1. Color Transformation Control The Color Transformation is used to correct the color information delivered by the sensor, improve the color reproduction of the camera, and make the image closer to the human visual perception. Figure 8-77 Color template The user can use a color template containing 24 colors and shoot this color template with a camera, the RGB value of each color may be different from the standard RGB value of the standard color template, the vendor can use the software or hardware to convert the RGB value that is read to the standard RGB value.

    8.Features The maximum pixel value (R ) equals, e.g., 255 for 8-bit pixel formats, 1023 for 10-bit pixel formats or 4095 for 12-bit pixel formats. 3) Enabling Gamma correction After enabling Gamma correction, set GammaValue to change the image brightness. The range of GammaValue is 0 to 4.00.
  • Page 140 8.Features 1) How it works a) LUT is short for "lookup table", which is basically an indexed list of numbers. b) In the lookup table you can define replacement values for individual pixel values. For example, you can replace a gray value of 0 (= minimum gray value) by a gray value of 1023 (= maximum gray value for 10-bit pixel formats).
