8.3 RGB processing
The RGB processing (see Fig.4) includes several features:
• Colour space matrix to handle different types of colour
sensors. The result is an optimum colour reproduction
through the minimization of colour errors. The default
matrix coefficients (positive or negative) can be adjusted
through an external interface.
• Separate and adjustable black offsets for
R, G and B signals.
• Separate gain controls for R and B signals dedicated to
white balance control. The colour temperature can be
adjusted independently of the colour matrix.
• Knee function (compression factor and knee point are
adjustable).
• Adjustable gamma function to compensate for the
non-linearity of display devices.
The RGB path has a reduced bandwidth (less than
1 MHz), which is required for CVBS output.
