Abstract
To provide an imaging device capable of reducing the amount of data with a simple method. An imaging device includes: a plurality of sensor elements which is arranged in a matrix shape and each of which generates a photoelectric conversion voltage in accordance with an input light level; and a read circuit which is coupled to bit lines provided while being associated with respective columns of the sensor elements, and amplifies and reads the photoelectric conversion voltages generated in the sensor elements by being exposed at predetermined timing. The read circuit outputs differential data of the read photoelectric conversion voltages generated in the respective sensor elements that are adjacent to each other in the same row or column.
