Classification: CPC H  G | IPC G  H

Claim 11:
12. An image processing device comprising:
a cutout part configured to cut out a plurality of image regions from an input image, the plurality of image regions comprises a first image region and a second image region;
a luminance change part configured to execute luminance change of each of the image regions cut out by the cutout part;
a luminance information calculation part configured to calculate luminance information that is information on luminance for each of the image regions cut out by the cutout part;
a switching image generation part configured to generate an image gradually changed from the first image region to the second image region, the image regions being cut out by the cutout part;
an image switching part configured to switch from the first image region to the second image region by crossfading, and
an output part configured to output the first image region and the second image region to a display,
wherein each of the plurality of image regions is a rectangular area of the input image, and
wherein each of the first image region and the second image region is a rectangular area of the input image,
wherein the image processing device further comprises:
a change coefficient calculation part configured to calculate a luminance change coefficient used for the luminance change of the luminance change part from the luminance information for each of the image regions calculated by the luminance information calculation part;
a switching image generation part configured to generate an image gradually changed from one image region to another image region while mixing the one image region with the other image region, on which the luminance change having been performed on the image regions by the luminance change part; and
a mixing ratio acquisition part configured to acquire a mixing ratio of the one image region in the switching image generation part,

wherein, when the luminance change part performs the luminance change on the one of the image regions combined by the switching image generation part, the luminance change part executes the luminance change using the luminance change coefficient obtained by changing the luminance change coefficient of the one of the image regions calculated by the change coefficient calculation part to the luminance change coefficient of the other image region calculated by the change coefficient calculation part according to the mixing ratio acquired by the mixing ratio acquisition part.
