A holding unit 24 generates and holds viewing history information corresponding to the video image from the information on the reproduced video image and the information on the reproduced time of the video image received from a video image display control unit 22. When receiving information of a video image to be displayed by a thumbnail from a thumbnail display control unit 21, a determination unit 25 receives viewing history information of a corresponding video image from the holding unit 24, and determines whether to display a corresponding thumbnail by a moving image or by a still image. A selection unit 26 selects, based on an instruction from the determination unit 25, which of still image data or moving image data is used as video image data to be displayed by the thumbnail for each thumbnail to be displayed by a list on a screen, and outputs the selected one to the thumbnail display control unit 21. In this way, when the thumbnail is displayed by a list, a plurality of thumbnails are able to be displayed by a moving image in a form that is appropriate for a viewing situation of a user.
