Abstract

See full text

A reset method of an photoelectric conversion device at least including a phototransistor having a first collector, a first base, and a first emitter, and a first field-effect transistor having a first source, a first drain, and a first gate, includes: connecting the first base, and one of the first source and the first drain of the first field-effect transistor by having a common region, or a continuous region, without a base electrode; supplying a base reset potential to the other of the first source and the first drain; and overlapping a time in which a first emitter potential is supplied to the first emitter and a time in which a first ON-potential that turns on the first field-effect transistor is supplied to the first gate.
