Filed: 1982-01-30
Abstract: PURPOSE:To eliminate the need for a mechanical shutter by arranging an photoelectric transducer section connected to a first switching element and a second switching element connected to the transducer section, excluding charges when the second switching element is under an opened state and obtaining signal charges when the element is under a closed state. CONSTITUTION:When beams are projected to a solid-state image pickup element 1, photoelectric transduction is executed in the photoelectric transducer sections D11-Dmn, and charges corresponding to luminous energy projected to the pickup picture element are generated. Signal charges are obtained when the charges generated are stored into the sources of MOS.FETs S11-Smn, but charges generated are excluded to connecting lines connecting drains and a power supply 20 and are not stored into the sources of the S11-Smn when MOS. FETs Q11-Qmn are under opened states. When the Q11-Qmn are under closed states, on the other hand, the charges generated are stored into the sources with the exception of the case when the S11-Smn are under opened states, and signal charges are acquired. Accordingly, a shutter is closed when the Q11-Qmn are under opened states, and opened when the Q11-Qmn are under closed states in succession at the same time or selectively, and an electronic shutter is formed.
