Abstract
An imaging device includes a pixel cell including: a first photoelectric converter that generates a first electrical signal; and a first signal detection circuit that detects the first electrical signal. The first signal detection circuit includes: a first transistor one of a source and a drain of which is electrically connected to the first photoelectric converter; a first capacitor having first and second ends, the first end being electrically connected to the other of the source and the drain of the first transistor, a reference voltage being applied to the second end; and a second transistor having a gate electrically connected to the first photoelectric converter. The pixel cell outputs, in one frame period, a first image signal and a second image signal in sequence, the first image signal being output when the first transistor is off, the second image signal being output when the first transistor is on.
