ABSTRACT:
A solid state imaging device according to the present invention includes a pixel transistor having a first electrode, a second electrode and a control electrode, a power supply terminal connected to the first electrode, a signal line connected to the second electrode, a reset bias terminal connected to the first electrode and the second electrode, a first switch connected between the power source terminal and the first electrode, a second switch connected between the reset bias terminal and the first electrode, and a reset switch connected between the reset bias terminal and the second electrode. The pixel transistor accumulates a charge corresponding to an amount of received light. The first switch is set in its off-state and the second switch and the reset switch are set in their on-states during a first period of a horizontal blanking period. Thereafter, a state of each of the first, second and reset switches is changed. The first switch is set in its on-state and the second switch and the reset switch are in their off-states in a second period of the horizontal blanking period succeeding to the first period.
