PURPOSE:To perform pickup sequence control accurately with a simple constitution, by detecting a start signal discriminable with a picture signal ahead the transfer of video signal to a storage means from a pickup means. CONSTITUTION:When an exposure is finished, a signl phi101K is produced from a terminal 101K to a selection gate 111 in timing. When the video signal for one frame's share is finished, since a start signal is outputted to an output terminal MO of a storage section 2, this is applied to a detection circuit 113 via an input terminal CI of a pickup section 1. The circuit 113 detects it and stops transfer pulses phiv1, phiv2, phih1, phih2, phiCT. Thus, the pickup sequence for one frame's share is finished. Thereafter, every time when a release button 15 is deeply depressed, the said pickup sequence can be repeated until the memory cell not in use is lost. |
