39.6.8 Color Space Conversion Unit

The color space conversion unit converts Luminance Chrominance color space into the Red Green Blue color space. The conversion matrix is defined below and is fully programmable through the LCD user interface.

R G B   = CSCRY CSCRU CSCRV CSCGY CSCGU CSCGV CSCBY CSCBU CSCBV   Y Yoff Cb Cboff Cr Croff  

Color space conversion coefficients are defined with the following equation:

CSC ij = 1 2 7 2 9 c 9 + n = 0 8   c n 2 n

Color space conversion coefficients are defined with one sign bit, 2 integer bits and 7 fractional bits. The range of the CSCij coefficients is defined below with a step of 1/128.
