摘要： An image playback apparatus and in image recording apparatus are designed to permit image playback from a selected position in an image file recorded to a directly accessible memory, such as a magnetic disk. During recording of an image file, the user can designate one or more candidate playback start positions in the file, and corresponding pointers are stored as part of the image file. When the file is to be played back, the playback apparatus accesses the pointer(s) and allows the user to select playback from the corresponding position(s) in the image file. Also the playback apparatus can rewrite pointers in an image file, whereby the user can designate candidate starting positions for future playback of the file.
