摘要： Photosensitive cells each includes a photodiode (1), a transfer gate (2), a floating diffusion layer portion (3), an amplifying transistor (4), and a reset transistor (5). Drains of the amplifying transistors (4) of the photosensitive cells are connected to a power supply line (10), and a pulsed power supply voltage (VddC) is applied to the power supply line (10). Here, a low-level potential (VddC_L) of the power supply voltage has a predetermined potential higher than zero potential. Specifically, by making the low-level potential (VddC_L) higher than channel potentials obtained when a low level is applied to the reset transistors (5), or channel potentials obtained when a low level is applied to the transfer gates (2), or channel potentials of the photodiodes (1), a reproduced image with low noise is read.

摘要： In each photosensitive cell, a photodiode 101, a transfer gate 102, a floating diffusion layer section 103, an amplifier transistor 104, and a reset transistor 105 are formed in one active region surrounded by a device isolation region. The floating diffusion layer section 103 included in one photosensitive cell is connected not to the amplifier transistor 104 included in that cell but to the gate of the amplifier transistor 104 included in another photosensitive cell adjacent to the one photosensitive cell in the column direction. A polysilicon wire 111 connects the transfer gates 102 arranged in the same row, and a polysilicon wire 112 connects the reset transistors 105 arranged in the same row. For connection in the row direction, only polysilicon wires are used.

摘要： A solid-state imaging device which can, in response to the problem of black-crush occurring in an image when strong light is enters the device, positively detect black-crush in a state in which a variance margin has been secured. The solid-state imaging device outputs a luminance signal in accordance with an amount of received light, and includes: a pixel circuit having a light-receiving element; a signal output circuit having a sampling transistor which outputs, from a second signal output line, a luminance signal in accordance with the amount of light received by the light-receiving element, based on an output signal from the pixel circuit; and a high-intensity judgment circuit which is coupled by the pixel circuit and a judgment input coupling capacitor, judges whether or not light entering the light-receiving element is of high intensity based on the output signal from the pixel circuit, and in the case of judging the entering light to be of high intensity, outputs a luminance signal indicating high intensity.
