Abstract
Systems and methods for converting between a first color space format and a second color space format are described herein. The system receives a video cell in a first color space format comprising a plurality of pixels. Each pixel in the cell has a luminance value and a chrominance value. The luminance values of each pixel are compared to determine the brightest pixel in the received cell. The cell is downsampled to generate a second cell in a second color space format. The second cell in the second color space format comprises a downsampled chrominance value that is computed based at least in part on the chrominance value of the brightest pixel. The method advantageously reduces tinting of a high intensity pixel by the chrominance component of a neighboring low-intensity pixel.
