Color correction circuit and image display apparatus using same
Abstract:
A color correction circuit includes a detection part configured to detect the luminance information and chromaticity histogram information of an input video signal of one of an RGB color space and a YCbCr color space, the chromaticity histogram information including chroma and hue information; and a control part configured to control the color reproduction of the video signal based on the luminance information and the chromaticity histogram information detected by the detection part. The detection part includes a hue detection part configured to convert the video signal to an HSV color space and to detect a hue of the video signal from hues of the HSV color space.
