Abstract
A range imaging device includes a light source unit, a light-receiving unit, and a range image processing unit that computes a distance to an object. The range image processing unit performs multiple measurements different in relative timing relationship between an emission timing and an accumulation timing, extracts a feature amount based on the amounts of charge accumulated at the measurements, determines whether reflection light of a light pulse has been received by pixels in a single path or via multipath propagation, based on tendency of the extracted feature amount, and calculates the distance to the object present in a measurement space in accordance with a result of the determination.
