Abstract
An image sensor device includes a plurality of pixel cells arranged in a matrix in a pixel array, and a timing control circuit that controls read-out of pixel information from the plurality of pixel cells. Each of the plurality of pixel cells includes a photodiode, a transfer transistor provided between the photodiode and a floating diffusion, a node reset transistor provided between a power supply terminal and the floating diffusion, a read-out capacitor whose one end is connected to the power supply terminal, a capacitor reset transistor provided between another end of the read-out capacitor and the floating diffusion, an amplification transistor that amplifies a voltage generated based on electric charges accumulated in the floating diffusion, and a selection transistor provided between the amplification transistor and a read-out line.
