Title: Solid-state image pickup device
Inventor: SUGIHARA SHOICHI
IPC: H04N5/351
Filed: 1989-01-13
Abstract: PURPOSE:To reduce flicker at a high-speed shutter time under the discharged lighting of 50Hz by correcting the photoelectric charge accumulation time of an image pickup element for the unit of field. CONSTITUTION:The output of an optical detector 11 photo-detecting external light around a solid-state image pickup device is integrated by a shutter speed set circuit 12. Since the shutter speed corresponding to the integration quantity of the optical detector 11 is corrected by changing the accumulation time of an image pickup element 3, accumulation quantity in the image pickup element 3 can be same for each field. Here, as a control signal, an accumulating signal before three fields can be used. Thus, the flicker can be reduced at the high- speed shutter time under the discharged lighting of 50Hz.
