    Abstract: PROBLEM TO BE SOLVED: To provide an improved image stream editing system and its method which can obtain one or plural representative frames by processing only once the sequence or shot. SOLUTION: An image stream of one or plural shots is processed, and every shot includes one or plural shot frames in a stream sequence. Each of buffers of a system can store an optional shot frame. In an extraction process, the shot frames are selected from the image stream at the inter-frame selection intervals and these selected shot frames (called buffer frames) are stored in a buffer so as to keep the sequence of buffers. Thus, the representative frames are extracted by selecting the frames via the shots and at almost even intervals in terms of time.

    Abstract: A method for obtaining a representative sequence of frames 340E from a sequence of shot frames 200 comprising the steps of extracting frames from the sequence at a selection interval and storing the selected frames in a buffer 340A and then, when the buffer is full, culling frames from the buffer at a buffer interval and increasing the selection interval by multiplying the original selection interval by the buffer interval. Preferably after culling frames for the buffer the remaining frames are compacted 340C to retain the order of the selected frames. These steps are repeated so that a representative sequence 340E of frames is obtained, with the selected frames being spaced at regular intervals in the original shot sequence, by processing the sequence only once and without knowing the length of the sequence in advance.
