ABSTRACT:
Sound associated with a scene which a still camera shot is picked up over a desired period of time starting from the instant which is a given time before the instant of depression of a release button of the camera. A shift register serves as a delay element for delaying an input time-serial digitized audio signal by the desired period of time, before the audio signal is written into an audio track of a magnetic disc which also has a video track for storing a video signal associated with the audio signal. During reproduction, one may hear the sound through a loudspeaker while watching the still picture displayed on a CRT or the like. The same sound may be reproduced repeatedly over a desired period of time.
