Abstract
An optical distance measurement apparatus includes a light source unit configured to emit pulsed light in units of the number of times determined in advance, a light receiving unit including a light receiving element which receives pulsed light reflected from a first object and configured to output a response signal in accordance with received light intensity of the pulsed light, and a control unit configured to generate a histogram by accumulating and recording the response signal output from the light receiving unit, corresponding to the number of times, in a time bin in accordance with time of flight of the pulsed light and calculate a distance to the object on the basis of the histogram. The control unit changes a light emission interval of the pulsed light by the light source unit within a unit of the number of times.
