| description | A distance-measuring imaging device includes a light source that applies light according to timing of a light emission signal; a solid-state imager that performs, for an object, exposure according to timing of an exposure signal, and generates raw data corresponding to an exposure amount of the exposure; a signal amount comparator that determines a magnitude relationship in signal amount in the raw data; and a distance calculator that generates and outputs a distance signal based on a determination result. The solid-state imager accumulates, in each of different signal accumulation regions for accumulating signals detected in a same pixel, a signal by exposure in an exposure period that differs in exposure signal timing. The signal amount comparator determines the magnitude relationship between the signals accumulated in the signal accumulation regions. The distance calculator calculates the distance to the object using an arithmetic expression selected depending on the determination result. |
