Abstract

To improve the image quality of image data in a solid-state imaging device that reads a signal according to a potential difference between respective floating diffusion regions of a pair of pixels. A pixel unit is provided with a plurality of rows each including a plurality of pixels. A readout row selection unit selects any of the plurality of rows as a readout row every time a predetermined period elapses, and causes each of the plurality of pixels in the readout row to generate a signal potential according to a received light amount. A reference row selection unit selects a row different from a previous row from among the plurality of rows as a current reference row every time the predetermined period elapses, and causes each of the plurality of pixels in the reference row to generate a predetermined reference potential. A readout circuit unit reads a voltage signal according to a difference between the signal potential and the reference potential.
