ABSTRACT:
An input image is digitized. The corresponding digital video data are reproduced while they are successively recorded on a magnetic video device. A successive recording control unit manages at which position of a successive recording area the digital data are to be successively recorded to realize the endless recording in a limitative recording area. When an event occurs, the control unit manages to exclude the recorded image before and after the corresponding event image from the endless recording area so that the event image can be held as an event recording image. Since the monitored image can be reproduced while it is recorded, it can be reproduced timely retroactively, and the image before and after an event occurs can also be reproduced instantaneously. Further, since the recording is continued while the image is reproduced, event images corresponding to plural events can be left.
