<p>With a time lapse recording/reproducing device for applying time lapse recording/reproducing processing to a video image signal gained through a video surveillance system and the like, a recording control unit (14) performs controlling by giving directions so that a signal obtained by applying picture compression processing to an inputted video signal in a picture compression/expansion circuit (11) provided with a means for intra-frame picture compression/expansion processing is recorded on rigid platters of a hard disk driver (12) as a moving picture and at the same time the foregoing signal is recorded intermittently on an optical disk of an optical disk driver (13), and, when an alarm signal is inputted, the foregoing signal is recorded on the rigid platters for a predetermined period of time as a moving picture and then has the recording operation ended, thus realizing a time lapse recording/reproducing device, whereby recorded moving pictures of the scenes just before and after the time when an alarm signal is inputted and also intermittently recorded pictures covering a long period can be obtained. <IMAGE></p> |
