Abstract:
1. A solid-state imaging device, comprising: a photosensitive region having a plurality of photosensitive cells which are two-dimensionally arranged, each photosensitive cell including a photoelectrical conversion element for generating a signal charge corresponding to an intensity of incident light, a transfer transistor for reading the signal charge in the photoelectrical conversion element and transferring the read signal charge to a floating diffusion layer section, an amplifier transistor for outputting an electrical signal corresponding to changes in potential of the floating diffusion layer section, and a reset transistor for resetting the potential of the floating diffusion layer section to a predetermined initial value; and a line for supplying a selected voltage to the drain of the reset transistor of each photosensitive cell, wherein: the line supplies, as the selected voltage, a first voltage and a second voltage which is lower than the first voltage, a potential of the second voltage is higher than zero potential, a potential of a channel, which is formed beneath a gate of the reset transistor of a given one of the photosensitive cells when a low level voltage is applied to the gate of the reset transistor, is lower than the second voltage, and one or more signal lines are shared by the photosensitive cells which are adjacent in a vertical scanning direction.
