IMAGE PROCESSOR, DISPLAY DEVICE, AND IMAGE PROCESSING METHOD

摘要

An image processor (10) according to the present invention includes: a luminance segmentation section (12) arranged to segment an input image into a plurality of regions having different luminance levels from one another; a spatial frequency calculation section (14) arranged to calculate a spatial frequency of each of the plurality of regions; a contrast adjustment section (16) arranged to adjust a contrast of each of the plurality of regions based on the luminance level and the spatial frequency calculated by the spatial frequency calculation section (14); and a merging section (18) arranged to merge the plurality of regions, whose contrasts have been adjusted by the contrast adjustment section (16), into one image.
