Abstract
A processor is provided that includes a primary memory of a processor and color conversion logic. The primary memory is to store a first color look-up table (LUT) related to a second color space. The color conversion logic is responsive to a received set of pixels, where each pixel of the set of pixels includes a color value in a first color space. The color conversion logic includes decision logic to selectively access the first color LUT and a second color LUT of a secondary memory to obtain a color value of the second color space that is associated with each pixel of the set of pixels based on a comparison of each pixel to at least one neighboring pixel.
