Title: Retrieving system for moving image
Inventor: SUZUKI TOMOMINE
IPC: G06F12/00
Filed: 1992-02-19
Abstract: PURPOSE:To operate the retrieving processing of a moving image at a workstation side, and to retrieve the objective moving image in a short time by preliminarily storing one part of the moving image as a still image in an outside storage device provided at the workstation. CONSTITUTION:At the time of extracting the still image from the moving image an interval time is inputted from an inputting device 6. Next, the reproduction of the moving image is operated by a moving image reproducing device 3. Then, a counter indicating the interval time of the extraction of the still image is cleared, whether or not the counter indicating the interval time of the extraction is matched with the input time is checked, and when they are matched, the extraction of the still image is operated by a still image extracting device 2. The extracted still image to which a position on a storage medium read from the moving image reproducing device 3 is added, is stored in an outside storage device 5. Thus, only a fast forwarding function and a reproducing function are necessary at the moving image reproducing device 3 side, so that a complicated processing such as a moving image retrieval can be realized only by a simple interface.
