Title: Image pickup device
Inventor: OKINO TADASHI
IPC: H04N5/30
Filed: 1983-12-20
Abstract: PURPOSE:To eliminate the effects of noise due to the trigger signal by having a shift of time between the actuation of a trigger circuit and the start of emission of the primary internal light and clearing the electrical information on the image pickup element which is produced during said shift of time. CONSTITUTION:For actuation of a trigger circuit B, no delay is virtually produced from an ON time point of a synchro-switch 29 and the working time is set at only several 10mus. Thus the high voltage of trigger disappears by a time point T2. When a transistor TR27 is turned on at a time point T1, a positive pulse is supplied via an input terminal 103a of a clock circuit 103. Then a pulse which is kept at a high level between time points T2 and T3 is produced within the circuit 103 and outputted through a terminal 103b to clear an image pickup element 101 via a driver 102. At the same time, a TR33 is turned on via a resistance 34 to short-circuit both terminals of a capacitor 26. In such a way, the effect of noise due to the trigger high voltage produced between time points T1 and T2 can be eliminated by a clearing action to the element 101 and the capacitor 26.
