Abstract:
1. An image signal processing apparatus comprising: a frame memory that stores image data of a complementary-color-field color-difference sequential system; an address generator, that generates, based on previously-provided distortion information, an address indicating a respective position on the frame memory corresponding to a position of each pixel in a screen to be displayed; a color-data generator, that generates color data of a point specified by the address by interpolating other color data of pixels, the pixels being in a same column included in a predetermined number of lines located above and below the point and having a same color line as a color line to be generated by interpolation; a color-data-related luminance-data generator, that generates first luminance data of the point specified by the address by interpolating luminance data of the pixels, the pixels being in the same column included in the predetermined number of lines located above and below the point and having the same color line as the color line to be generated by the interpolation; a luminance-based-data generator, that generates second luminance data of the point specified by the address by interpolating the luminance data of the pixels, the pixels being in the same column included in the predetermined number of lines located above and below the point; and a complementary-color-data generator, that generates complementary-color data of the point specified by the address based on the color data, the first luminance data, and the second luminance data, the address generator, the color-data generator, the color-data-related luminance data generator, the luminance based data generator and the complementary color data generator being implemented by a processor.
