Patent ID: 8294740

Claim:
An image processor that corrects image signals corresponding to sub-pixels which form one pixel, comprising: a shift amount storage section that stores shift amounts of display positions of display sub-pixels corresponding to the sub-pixels which form a display pixel with respect to a predetermined reference position within a display image; a frequency analysis section that analyzes a spatial frequency of an input image and outputs an analysis result; and an image signal correcting section that corrects image signals corresponding to the sub-pixels, which form each pixel of the input image, on the basis of the analysis result and the shift amounts, wherein the image signal correcting section performs different correction processing according to the spatial frequency, and the image signal correcting section omits the correction processing when the input image has a frequency component equal to or larger than a predetermined threshold value and performs the correction processing when the input image does not have a frequency component equal to or larger than the predetermined threshold value.
