Claim:
1. A method for generating downscaled image data comprising: determining adaptive color conversion coefficients associated with input image data in a first color space based on an illumination indicator associated with the input image data, wherein the adaptive color conversion coefficients are to convert the input image data from the first color space to a second color space, and wherein the second color space is a luma chroma separated color space; applying the adaptive color conversion coefficients to the input image by a linear conversation operation on the input image to convert the input image data to color converted image data in the second color space downscaling the color converted image data to generate downscaled color converted image data, wherein the downscaling comprises at least one of a horizontal downscaling or a vertical downscaling of color channels of the color converted image data; and storing the downscaled color converted image data associated with the color converted image data to an input image buffer.
