1. A method of encoding a video signal including a frame, the method comprising:
generating, by a pre-processor circuit, a Bayer histogram from the video signal;
deriving, by an encoder coupled to the pre-processor circuit, a chroma histogram from the Bayer histogram;
modifying, by the encoder, a chroma quantization step size for the frame based on the chroma histogram.
