Abstract
An optical sensor comprises a light-emitting element configured to emit light in a region where an object is present; a light-receiving element configured to receive reflected light from the object; a generation unit configured to generate a histogram indicating a relationship between a time from emission of the light by the light-emitting element to reception of the reflected light by the light-receiving element and an intensity of the reflected light received by the light-receiving element; a first calculation unit configured to calculate skewness of the histogram; and a second calculation unit configured to calculate a distance between the optical sensor and the object with reference to the histogram and the skewness.
