Example:
Input 1280 × 1024 Output = 640 × 480
Hratio = 1280/640 = 2
V
ratio = 1024/480 = 2.1333
The decimation factor is 2 so 32/16.

37.5.4.2 Color Space Conversion
This module converts YCrCb or YUV pixels to RGB color space. Clipping is performed to ensure that the samples
value do not exceed the allowable range. The conversion matrix is defined below and is fully programmable:
