Abstract
An imaging device includes a plurality of arranged imaging elements each including: a light-receiving element configured to generate charge from received light by photoelectric conversion, a floating diffusion configured to convert the charge generated by the light-receiving element into voltage, a charge transfer switch configured to transfer the charge from the light-receiving element to the floating diffusion, a reset switch configured to reset the voltage of the floating diffusion, and a source follower configured to amplify the voltage of the floating diffusion. The reset switch is configured to reset the voltage of the floating diffusion a plurality of times for each of predetermined pixel groups in a single image data acquisition period. The charge transfer switch is configured to transfer the charge from the light-receiving element to the floating diffusion a plurality of times for each of the pixel groups in the single image data acquisition period.
