SOLID-STATE IMAGE PICKUP DEVICE AND DRIVING METHOD THEREFOR, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a CCD (Charge Coupled Device) solid-state image pickup device which is adaptive to a large signal and secures S/N characteristics in the case of a small signal. SOLUTION: The solid-state image pickup device includes: a plurality of light sensing section 2s; a plurality of vertical transfer registers 3 configured to transfer signal charge of the light sensing sections 2 in the vertical direction; and a horizontal transfer register 4 configured to transfer the signal charge in the horizontal direction. The solid-state image pickup device further includes a floating gate amplifier 7 that is placed at an output side of the horizontal transfer register 4; a floating diffusion amplifier 9 that is placed in a horizontal transfer register 8 which is provided at a stage subsequent to the floating gate amplifier 7; and an overflow drain mechanism 10 that is placed in the horizontal transfer register 8 between the floating gate amplifier 7 and the floating diffusion amplifier 9.
