Abstract
In a still picture recording apparatus such as an electronic still camera, an audio signal compressed in its time base is recorded on a magnetic disk together with a video signal. In order to relate the timing of recording the audio signal to that of the video signal, the audio signal to be recorded is processed in an audio signal processing circuit in response to the manipulation of a manual switch, and the video signal to be recorded is processed in a video signal processing circuit after a required delay time relative to the audio signal, so that the audio signal and the video signal can be recorded in matching relation without the possibility of mismanipulation and without the need for troublesome recording procedures.
