ABSTRACT:
Color saturation in chroma correction is reduced. Hence, a two-dimensional histogram is generated in association with the luminance and chroma levels of an image for one frame. An ease of saturation of the image is calculated from the two-dimensional histogram. A chroma gain is set according to the ease of saturation. Color-difference signals undergo chroma correction according to the chroma gain k.
