Title: Still video camera
Inventor: MIYAKE IZUMI
IPC: H04N5/765
Filed: 1986-09-01
Abstract: PURPOSE:To exactly synchronize the writing of a still video signal in a magnetic disk by constituting the titled camera so that a synchronizing signal generating circuit is not reset after a second switch of a two-phase stroke shutter releasing button is turned ON. CONSTITUTION:If the first step of a releasing button 29 is depressed, a motor 14 is started. Phase detection pulses PG outputted at a rate of one piece per one turning of the magnetic disk 11 are inputted to the synchronizing signal generation circuit 31 via a gate circuit 33, and the circuit 31 is reset. Accordingly, a vertical/horizontal synchronizing signal in synchronism with the pulse PG is supplied respectively to a solid-state electronic image pickup device 24 and a recording signal processng circuit 25. If the button 29 is further depressed to the second step, the gate of the gate circuit 33 is closed, and the phase detection pulses PG are no longer inputted to the synchronizing signal generation circuit 31. As a result, the circuit 31 continues to generate a synchronizing signal equivalent to one field.
