SOLID-STATE IMAGE PICKUP ELEMENT AND METHOD FOR CONTROLLING SAME

摘要

A transfer circuit (20) transfers signal charges of an accumulating region (15) to a floating diffusion region (30) when the transfer circuit is operating and interrupts the transfer of the signal charges when the transfer circuit is not operating, by means of a transfer gate (21) which is turned on and off corresponding to transfer control signals (TG). A pixel control circuit (200) controls the transfer circuit (20), corresponding to the light receiving level of a pixel circuit (100), so as to extend the operation period of the transfer circuit (20) compared with the case where the light receiving quantity is lower than a predetermined quantity when the light receiving quantity is a predetermined quantity or more.
