Abstract
An image sensor comprising a plurality of light-receiving elements, each of which consists of a pair of photodiodes connected in series-opposition. Since the voltages generated at these photodiodes when equal intensities of light is projected on them are equal to each other, no current leaks, thereby generating no noise.
