Abstract:
1. An apparatus to reproduce a preferred color, the apparatus comprising: a color distribution analysis module to analyze a distribution of colors from at least one lattice cell in an input image; a dominant color extraction module to extract a dominant color from the at least one lattice cell according to a result of the analysis; a conversion domain determination module to determine a single conversion domain from a predefined conversion domain or domains, to be processed in a color space, if the extracted dominant color accounts for more than a threshold percentage of the input image; and a color conversion module to convert the colors in the input image that belong to the determined single conversion domain, wherein the color conversion module converts the colors that belong to the single conversion domain so that the colors can be approximated to a target color, and the single conversion domain comprises the extracted dominant color that accounts for more than the threshold percentage of the input image.
