Claim Text:
1. A device that combines a first image photographed with a first amount of exposure and a second image photographed with a second amount of exposure lower than the first amount of exposure, thereby generating a combined image having a wider dynamic range than a dynamic range for the first amount of exposure of the first image and the second amount of exposure of the second image, the device comprising: a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute: wherein the obtaining of the representative luminance value sets the combining ratio at the given luminance value for the pixel in the background region such that the smaller a statistical luminance value that is a statistical central value for the representative luminance value of each of the at least one motion region, the higher the combining ratio at the given luminance value.
