Abstract
A video processing system is provided for reducing distortion in video signals. The system includes a first transfer function that applies a transfer function to a received video signal to generate a gamma corrected video signal in a first color space; and a first matrix component that transforms the gamma corrected video signal in the first color space to a gamma corrected signal in a second color space, and extracts a luminance component from the gamma corrected signal in the second color space. Moreover, the system includes a second transfer function that generates a gamma corrected downsampled video signal in the first color space, and a second matrix component that transforms the gamma corrected video signal in the first color space to a gamma corrected video signal in the second color space, and extracts the chroma component in the second color space.
