Driving method for solid-state image pickup device

Abstract

A solid-state image pickup device of the frame transfer system is designed to provide two types of image signals. A light receiving section of the solid-state image pickup device adopts a six-phase drive in which second and fifth transfer clocks φ2 and φ5 are set high at a first image pickup operation so that a potential well is formed respectively under the corresponding transfer electrodes. After completion of the first image pickup operation, information charges in the potential well under the transfer electrode corresponding to the second transfer clock φ2 are transferred to the potential well under the transfer electrode corresponding to the fifth transfer clock φ5. At a second image pickup operation, the second and fifth transfer clocks φ2 and φ5 are again set high so that a potential well is formed respectively under the corresponding transfer electrodes. After completion of the second image pickup operation, the respective potential wells are transferred and output independently.
