Original Abstract Submitted
a ranging device includes a light receiving unit including pixels for detecting pulsed light reflected by an object, a binning processing unit for converting signals output from unit regions each including at least one pixel into signals corresponding to pixel blocks each including at least two unit regions, a data accumulation unit for accumulating, for each pixel block, information indicating a relationship between a class determined according to a time period from emission to detection of the pulsed light and a frequency, based on the signals output from the binning processing unit, a reflected light determination unit for extracting, for each of the unit regions, a candidate of a class including a signal based on a reflected light from the object from the information, and a distance calculation unit configured to calculate a distance to the object corresponding to each of the unit regions based on the candidate.
