Abstract

A light sensor or the like that has an improved measurement speed is realized. A light sensor includes a computation unit that computes a distance between the light sensor and a sensing object on the basis of a difference between a center position of reflection light, which indicates a center position of distribution of light reception probability of a first light receiving unit in a first histogram, and a center position of reference light, which indicates a center position of distribution of light reception probability of a second light receiving unit in a second histogram.
