摘要:
An image correction circuit includes: a region determining means for determining an intermediate luminance region in each image frame on the basis of the description of input image data; a luminance distribution acquiring means for acquiring a luminance distribution of input image data in the determined intermediate luminance region in each image frame; a determining means for determining an input/output characteristic line in each image frame by adaptively changing a predetermined reference input/output characteristic line on the basis of the acquired luminance distribution of the intermediate luminance region, the input/output characteristic line defining the substance of image correction on input image data; and a correction executing means for executing image correction on input image data on the basis of the determined input/output characteristic line.
