1. An image processing device, comprising: a loop moving image generating unit configured to: divide shot images into at least two segments in spatial direction based on a plurality of said shot images shot at different points in time; and generate, from said shot images, images playable as a loop moving image, based on images of motion segments in which a subject with motion is included; and a segment image generating unit configured to: clip out, from a high-resolution image with higher resolution than said shot images, an image of a region corresponding to a still segment which includes a subject with no motion; and generate a segment image which is one still image, based on said image in said region corresponding to said still segment, wherein said loop moving image generating unit is configured to generate said loop moving image, based on said shot images converted to the same resolution as that of said high-resolution image.
