Abstract

A ranging device includes: a binning processing unit configured to perform binning processing for one or more frequency distributions held in one or more frequency distribution generation units of frequency distribution generation units; a determination unit configured to determine whether a component of reflected light from an object is included in the frequency distribution subjected to the binning processing; a binning setting unit configured to change the number of the frequency distribution generation units to be subjected to the binning processing performed by the binning processing unit in accordance with a result of the determination by the determination unit; and a distance calculation unit configured to calculate a distance to the object based on a time interval corresponding to a reception time of the reflected light when the determination unit determines that a component of the reflected light is included in the frequency distribution subjected to the binning processing.
