Title: Driving method for solid-state image pickup device
IPC: H04N5/341
Filed: 1992-04-01
Abstract: PURPOSE:To suppress occurrence of blooming even when an object with very high brightness is picked up without reducing a signal charge saturation capacitance of a photoelectric conversion section. CONSTITUTION:A high level potential and a low level potential of a drive pulse 1 to sweep out a false signal charge in existence before a signal charge is read from a photoelectric conversion section to a vertical transfer section are different respectively from a high level potential and a low level potential of a drive pulse 3 to transfer a signal charge read from the photoelectric conversion section to the vertical transfer section to a storage section. Furthermore, since a voltage to take a sufficient signal charge saturation capacitance of the photoelectric conversion section for a period other than the period when the signal charge read from the photoelectric conversion section to the vertical transfer section is transferred to the storage section is applied to a semiconductor substrate, the solid-state image pickup device is driven without impairing the dynamic range.
