PROBLEM TO BE SOLVED: To provide an image processing unit that suppresses production of color moire in a decoded image. SOLUTION: A gradation conversion section 71 applies gradation modulation processing to a color mosaic image M to generate a modulation color mosaic image Mg. Color difference image generating sections 72, 73 use the modulation color mosaic image Mg to respectively generate color difference images C, D. A luminance image generating section 74 uses the modulation color mosaic image Mg and the color difference images C, D to generate a luminance image L. A color space conversion section 75 applies color space conversion processing to the color difference images C, D and the luminance image L to generate a modulated image. Gradation inverse conversion sections 76-78 apply modulation inverse conversion to the modulated image to respectively generate output images R, G, B. |
