PROBLEM TO BE SOLVED: To provide an image processor for performing the flexible color correction of an image at high speed. SOLUTION: The image processor for for automatically correcting colors of an image represented in a digital color space having N colors includes: a memory; a general processor which derives (n) grid correction color data representing correction colors corresponding to (n) (n<N) grid colors to generate a three-dimensional color conversion table holding the grid correction color data by the grid colors in the memory; and a dedicated processor which acquires original color data stored in the memory, acquires unit data composed of a plurality of grid correction color data corresponding to a plurality of grid colors close to the color of a pixel of an interest from the three-dimensional color conversion table based upon the original color data, and derives correction color data corresponding to the original color data by linear interpolation operation using the unit data to generate a corrected image in which colors of respective pixels are represented with the correction color data.
