IMAGE PROCESSING DEVICE, IMAGE DISPLAY DEVICE, AND IMAGE DISPLAY METHOD

摘要

An image device includes: maximum/minimum color information detection means (3, 51, 52) for detecting a value (CMAX) of a maximum gradation or a value following the maximum gradation of a color signal and a value (CMIN) of a minimum gradation or a value following the minimum gradation of the color signal as color information on an input image signal; correction parameter generation means (53) for setting a correction parameter (Pa) according to input image signal color information (CMAX, CMIN); and gradation correction means (6) for correcting the gradation of each color component of the input image signal according to the correction parameter (Pa). It is possible to suppress color collapse and improve the contrast.
