Image signal processing apparatus, image signal processing method, and program

An image signal processing apparatus includes: a color-data generator that generates color data of a correction coordinate point by interpolating color data of pixels in the same color line above and below the correction coordinate point; a first luminance generator that generates first luminance data of the correction coordinate point by interpolating the luminance data of the pixels in the same color line above and below the correction coordinate point; a second luminance generator that generates second luminance data of the correction coordinate point by interpolating the luminance data of the pixels above and below the correction coordinate point; and a complementary-color-data generator that generates the complementary-color data of the correction coordinate point based on the generated color data, the first luminance data, and the second luminance data.
