METHOD AND APPARATUS FOR COLOR CORRECTION

摘要

For the purpose of obtaining a color correction device and a color correction method capable of separating an achromatic color from a chromatic color and independently controlling the color, and a color correction application device where the color correction method is applied, the color interpolation is performed along the locus of the color change of an input signal by dividing a color space of the input signal into blocks to surely include the locus changing from black to white passing through a center part based on the locus (chromatic locus) changing from black to white surrounding a color region to be handled by an input image equipment and the locus (achromatic locus) changing from black to white passing through the center part of the color region to be handled by the input image equipment. An achromatic part present in the center part of the color space is separately handled from a chromatic part present in its peripheral part. <IMAGE>
