ABSTRACT:
An apparatus for driving a solid-state image sensor includes a sensor portion for performing a photoelectric conversion, a vertical transfer register for reading information from the sensor portion, a memory for storing information from the vertical transfer register, and an eliminating unit for eliminating information from the sensor portion, wherein the information in the sensor portion is eliminated by the eliminating unit intermittently two or more times in one field interval, whereby information storage time is controlled. In one field interval, operation of the eliminating unit is performed successively every time T.sub.2 after time T.sub.1 from a vertical synchronizing signal, the information from the sensor portion is read in the vertical shift register successively, at every operation of the eliminating unit, a time T.sub.3 after the end of this operation, and the first time T.sub.1, second time T.sub.2 and third time T.sub.3 are controlled so as to vary independently or in association, whereby virtual storage time of the sensor portion in one field interval is controlled.
