Color Space Conversion
Figure 41-5. Resize Examples
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:
Example of programmable value to convert YCrCb to RGB:
