Claim 12:
13. An image processing method executed by an image processing device, the image processing method comprising:
inputting an input image;
cutting out a plurality of image regions from the input image, the images regions being different parts of the input image;
a luminance information calculation step of calculating luminance information for each of the image regions that has been cut out, the luminance information being information on luminance; and
a luminance change step of executing luminance change of a corresponding image region on the image regions on a basis of the luminance information for each of the image regions calculated in the luminance information calculation step to change a luminance of one of the image regions calculated in the luminance information calculation step into a luminance of another of the image regions calculated in the luminance information calculation step,
wherein each of the plurality of image regions is a rectangular area of the input image.
