Abstract
A video signal from a camera portion is supplied as moving picture data to a moving picture recording portion. The video signal is recorded by the moving picture recording portion with a time code attached thereto. The video signal from the camera portion is supplied to a series circuit of frame memories. The video signal is read from the memories every frame interval and supplied to a comparison calculation portion. In the comparison calculation portion, a change in scene is detected by comparison calculation (judgment of existence of correlation) of video signals having a time difference of one frame therebetween and the detection information of the change in scene is supplied to a controller. When a change in scene is detected, a one-frame portion of video signal is read from the memory under the control of the controller and the read signal is supplied to a still picture recording portion as still picture data to be recorded thereby. At this time, the one-frame portion of video signal is recorded together with a time code which is attached to the one-frame portion of video signal when it is recorded by the moving picture recording portion.
