Abstract
The invention provides a night-vision imaging apparatus including: a light emission unit that emits infrared light; a solid-state imaging device that converts the infrared light into a first signal; a light-emission control unit that allows the light emission unit to emit the infrared light which is modulated according to a temporally pseudo-random first modulation; and an extraction unit that extracts, according to the first modulation, a signal corresponding to the infrared light emitted by the light emission unit from the first signal.
