<P>PROBLEM TO BE SOLVED: To suppress coloring of an achromatic subject. <P>SOLUTION: A personal computer 100 is provided with: luminance and chromaticity calculation means which calculates the luminance and chromaticity of each pixel on the basis of the value of each pixel of image data; locus determination means which determines an achromatic locus in a RAW data space; plane calculation means which calculates a plane including the coordinates of the pixel in the RAW data space; intersection calculation means which calculates the intersection of the plane and the achromatic locus; intersection chromaticity calculation means which calculates the chromaticity of the intersection; and conversion means which when the chromaticity of the pixel is close to the chromaticity of intersection, converts the chromaticity of the pixel to be close to the achromatic chromaticity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
