Abstract
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. A sensor clock that controls the image capturing timing of the ToF sensor is the clock specific to the rangefinder, which is different from a light source unit clock that controls the light emission timing of the light sources of the light source unit. The rangefinder creates a difference calculation formula of a plurality of distance calculation formulas used to calculate the distance from each light source to the rangefinder to calculate the distance to the object using the created difference calculation formula.
