ABSTRACT:
A photographing and recording method and apparatus for an electronic still picture camera of the type in which an image is picked up by a combination of a mechanical or electrooptical shutter and an image pickup device and the resulting picture signal is recorded on a magnetic disk, eliminate any undesired power consumption due to the preliminary revolution of the magnetic disk. The revolution of the magnetic disk is started upon the depression of the shutter button and the revolution is controlled at a constant speed by a velocity servosystem. The phase of the vertical synchronizing signals for reading the signal charges from the image pickup device and recording the signal on the disk after the exposure is shifted with respect to the vertical synchronizing signals for the extraneous charge draining operation of the image pickup device before the exposure and the phase-shifted vertical signals are reset in response to the beginning of the next exposure thereby controlling the phase difference between the vertical synchronizing signals and the rotational period of the disk at a desired value.
