An electronic device including an image pick-up element and an image
pick-up device including a recording and reproducing element are provided
in which shutter sound is muted or decreased, so that the artificial
electronic shutter sound is not mixed with audio signals when recording
is performed and the shutter sound may not be reproduced at the time of
reproduction. The shutter sound generated by the electric artificial
shutter sound data unit and the shutter sound of the reverse phase stored
in advance in the sound effect data unit are mixed to cancel each other
after the occurrence of the electric shutter sound, and in the canceled
state audio signals are recorded.
