Abstract

An imaging apparatus includes: a light emitter that irradiates a subject with light; and a solid-state imaging device that includes pixel units each of which converts received light into a signal charge, and a signal processor that calculates distance information indicating a distance to the subject. When one or more of the pixel units receive reflected light which is the light irradiated by the light emitter and reflected by the subject, the signal processor (i) calculates the distance information for each of the pixel units by a time-of-flight (TOF) method that uses signal charges, each of the signal charges being the signal charge into which the received light is converted by each of the pixel units, and (ii) calculates, for each of one or more of the pixel units, variation information indicating an amount of variation regarding the distance indicated by the distance information.
