ABSTRACT:
A still image recording apparatus in which an image PU device is reset independently of synchronization of a system when a trigger pulse of an exposure operation is input, and a storage photoelectric charge of the device is discharged and storage of a new photoelectric charge is started. After a predetermined exposure time elapses, the photoelectric charge is read out from a photoelectric converter to a transfer register which is shielded from light. A scanning transfer pulse is stopped until a vertical synchronizing signal of the system is input, so that an image signal is stored in the transfer register. After the system vertical synchronizing signal is input, the scanning transfer pulse is enabled again in synchronism with the system vertical synchronizing signal to perform scanning of the image PU device, thereby reading out the image signal.
