To achieve a configuration of controlling a light source unit having a plurality of light sources and a rangefinder by individual clocks to allow for setting the light sources at optional positions. The output light of a plurality of light sources of the light source unit is reflected from an object's surface, and a ToF sensor captures the reflected light to calculate the distance to the object.
