ABSTRACT:
A photoelectric conversion element includes a photoelectric conversion portion for generating and storing a charge according to incident light, an amplifying portion having a control region for generating a signal output according to the charge received in the control region from the photoelectric conversion portion, a transfer control portion for transferring the charge generated and stored in the photoelectric conversion portion to the control region of the amplifying portion, a reset-purpose charge draining region for draining the charge transferred to the control region of the amplifying portion, and a reset-purpose control region for controlling the reset-purpose charge draining region. A reset operation can be performed without operating the amplifying portion. Also, a photoelectric conversion apparatus having high sensitivity and low dissipation power can be obtained.
