Abstract
An imaging device includes pixel units, a control unit, and a correction unit. The control unit causes each pixel unit to output first and second signal. The first signal is a potential of a floating diffusion held when the charge accumulated in a photoelectric conversion unit is transferred upon a transfer switch being closed. The second signal is a potential of the floating diffusion held when a reset switch is closed with the transfer switch being open. The correction unit generates, with respect to the first and second signals output by each pixel unit, the pixel signal by subtracting a correction amount from a signal intensity of the first signal. The correction amount is a product of a signal intensity of the second signal and a coefficient determined in advance in accordance with a position of each pixel unit.
