Abstract
An image processor that corrects image signals corresponding to sub-pixels which form one pixel, includes: 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 using a predetermined reference position within a display image as a reference position; 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 performs correction processing of 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.
