Abstract
A range finding device includes a plurality of light sources, each configured to emit irradiation light to an object; a plurality of light reception units configured to receive reflection light coming from the object when the irradiation light hits and reflects from the object, the number of plurality of light reception units being the same number of the plurality of light sources; and circuitry configured to shift light emission timing of at least one or more light sources among the plurality of light sources; and calculate a distance to the object based on information output from each of the plurality of light reception units.
