Method and apparatus for correcting smear in a charge-transfer type solid-state image pick-up device

摘要

A method for driving a charge-transfer type solid-state image pick-up device, wherein the charge-transfer type solid-state image pick-up device comprises: high sensitivity photoelectric conversion elements for executing photoelectric conversion with relatively high sensitivity; low sensitivity photoelectric conversion elements for executing photoelectric conversion with relatively low sensitivity; and vertical transfer channels for transferring signal charges from said high sensitivity photoelectric conversion elements and said low sensitivity photoelectric conversion elements, the method comprising a charge transfer step of individually reading/transferring first signal charges from said high sensitivity photoelectric conversion elements and second signal charges from said low sensitivity photoelectric conversion elements onto said vertical transfer channels, without executing a high speed charge transfer operation for the vertical transfer channels after exposure of said solid-state image pick-up device.
