A thumbnail image generating unit (113) generates thumbnail images from a plurality of images having a sequential relation. A thumbnail image displaying unit (118) displays the thumbnail images generated according to the sequential relation. A thumbnail image designating unit (103) receives a designation of a thumbnail image from among the thumbnail images. An enlarging unit generates an enlarged image of a designated thumbnail image. An enlarged image displaying unit displays the enlarged image. A forward-advance designating unit (307) designates a forward advance of the enlarged image displayed by the enlarged image displaying unit according to the sequential relation. The thumbnail image designating unit (103) takes a thumbnail image required to be enlarge as a result of a designation of the forward advance according to the sequential relation by the forward-advance designating unit (307) as a designated thumbnail image. |
