Abstract:
1. A method performed by at least one of a computer processor and a solid-state device for conversion between a first color space format and a second color space format, the method comprising: receiving a first cell comprising a plurality of pixels, wherein the first cell is represented by the first color space format, and wherein each pixel in the first cell has a luminance value and a chrominance value; comparing the luminance values of the plurality of pixels in the first cell to determine a brightest pixel in the first cell, wherein the brightest pixel in the first cell has a luminance value at least as great as each of the other pixels in the first cell; setting a downsampled chrominance value for the first cell equal to the chrominance value of the brightest pixel in the first cell; generating a downsampled first cell, the downsampled first cell represented by the second color space format and comprising the downsampled chrominance value for the first cell.
