Abstract

PURPOSE:To shorten the retrieval time of a video image required in a moving picture by recognizing a content of a moving picture medium in a form of a still picture without reproducing the entire moving picture medium by a video reproducing device. CONSTITUTION:A video input/output device 3 is provided with a video image state change extract section 4, plural frame memory sections 5 and a frame picture coding section 6, and a frame picture storage medium 8 and a pushbutton input device 7 are connected to extract a characteristic point as a still picture when a video signal is fetched, index information is added to the picture and the result is stored and the still picture is displayed on a multi-screen at the reproduction.

2. Description of the Related Art In a conventional apparatus of this type, as shown in FIG. 2, a moving image captured by a video input is reproduced by a person on a video monitor 2 sequentially by using a video reproducing device 1 or the like. Then, a method of searching for a moving image is adopted by confirming it or by addressing the moving image in advance and managing it.

As described above, in the search and display of moving images, since the video is analog information, it is difficult to search in the following two points.・ The moving image medium is often tape,
Search takes time. -When moving images are encoded and digitized, the amount of data becomes enormous. For these reasons, it has been desired that search / display can be quickly performed without reproducing all video images.
Therefore, the present invention shortens the search time of a required video in a moving image by allowing the contents of the moving image medium to be grasped without reproducing all of the moving image medium with a video player. .

According to the present invention, when a video image is captured, a still image matching predetermined information (change point, characteristic point) is encoded and stored, so that one moving image medium is recorded. A group of frame images is generated and saved. By using this, a plurality of video images are simultaneously displayed on the video monitor when the video image is reproduced, and the selection is performed.

Information about feature point extraction is instructed. This means designation of a region of an image, designation of a state change target (color component, luminance component, pattern information) and its difference, and designation of a sampling time taken as a frame image from an NTSC signal during input of a moving image. When a state change equal to or greater than the specified difference is detected in a specified area between two frames sampled of a moving image under the conditions specified above, one of the two sampling frame images, which is later in time series, is detected. The frame image of the frame image is stored in the frame image storage unit 8 as a digital compressed image in the frame image encoding unit 6.
Save to. After that, each time a state change is detected, the encoded frame image is sequentially saved.
