Patent attributes
A per sub-pixel luminance information-generating unit enters per-pixel luminance information, and generates respective pieces of luminance information on target pixel-forming three sub-pixels using luminance information on the target pixel and an adjacent pixel. A per sub-pixel chroma information-generating unit enters per-pixel chroma information, and generates respective pieces of chroma information on the target pixel-forming sub-pixels using chroma information on the target pixel and an adjacent pixel. The target pixel and the pixel adjacent to the target pixel are used to generate respective pieces of the luminance information on the target pixel-forming three sub-pixels. Since the pixels used to generate the luminance information on a per sub-pixel basis are the same ones used to generate the luminance information, the occurrence of color irregularities is inhibited between an original image and a multi-value image displayed on a per sub-pixel basis.
