A moving image data management apparatus which manages one or plural representative images in correspondence with a moving image recorded on a storage medium. The apparatus generates a thumbnail based on a frame image selected in a desired selection base in an arbitrary section designated in the moving image, in correspondence with the section, and records the thumbnail. The thumbnail, corresponding to the moving image, is stored in correspondence with section information indicating the designated section, position information indicating the position of the selected frame image, and Type ID indicating the selection base. Among the thumbnails registered in this manner, a thumbnail is selected by referring to the Type IDs in correspondence with a processing purpose and is presented to a user. As the selection base which is information on generation of thumbnail is held as an attribute of the thumbnail, and a thumbnail appropriate to processing can be presented, operability in processing using thumbnail can be improved.
