Abstract:
1. A solid-state image pickup device comprising: a plurality of pixels each including a photoelectric conversion unit, a floating diffusion region, a transfer switch for transferring an electric charge from the photoelectric conversion unit to the floating diffusion region, and an amplification transistor whose gate is electrically connected to the floating diffusion region; and a scanning circuit for supplying a drive pulse to a control node of the transfer switch, wherein the transfer switch is turned off by holding for a predetermined period a first level of the drive pulse supplied from the scanning circuit to the control node of the transfer switch, wherein the transfer switch is turned on by holding for a predetermined period a second level of the drive pulse supplied from the scanning circuit to the control node of the transfer switch, and wherein a first period for changing from the second level of the drive pulse to the first level of the drive pulse is longer than a second period for changing from the first level of the drive pulse to the second level of the drive pulse.
