摘要： PROBLEM TO BE SOLVED: To solve the problem that a recording medium used for recording a moving image is a taped medium, photographed images are continuously arranged on a tape always in a photographed order, the photographed images are always stored in a tape unit and it is needed to be done from the head of the tape in order of time when appreciating.
SOLUTION: A sequential medium such as a tape is not used for recording the moving image but an electronic camera is used, performing recording in a medium which forms an image file of one unit for every photographing of each cut to which random access is made possible such as a hard disk. A large quantity of image files generated upon photographing and having units from several seconds to several ten seconds are automatically classified according to specified conditions of a photographing time range, place and the like and image files in a group are continuously played back in a group unit by a user without feeling presence of each image file.
