Image processor, image display device, and image processing method

摘要

An image processor that corrects an image signal, includes: a frequency analysis section that analyzes a spatial frequency of a luminance component of the image signal; a luminance component correction amount calculating section that calculates an amount of correction of the luminance component of the image signal according to the analysis result of the frequency analysis section only for an image signal in a predetermined luminance level range of a predetermined spatial frequency band; and a luminance component correcting section that corrects the luminance component of the image signal by using the amount of correction calculated by the luminance component correction amount calculating section.
