摘要：
Change image detecting devices and methods are disclosed. In one example, a determination unit partially compares a first image and a reference image and determines whether there is a change therebetween. If the determination unit determines no change between the first image and the reference image, the change image detecting unit selects a second image, which is temporally later than the first image and stored in a first storing unit, as a new image to be processed and the determination unit partially compares the second image and the reference image at a different position than previously compared and determines whether there is a change between the second image and the reference image. If the determination unit determines change between the first image and the reference image, a change image detecting unit detects the first image stored in the first storing unit as the change image, and stores the first image in the second storing unit.
