Maintain appropriate measurement accuracy in the distance measuring device. [Solution] The control device includes a control unit that controls the light source of the distance measuring device. The distance measuring device derives multiple depth values ​​relating to the distance to an object based on the time from when light is emitted from the light source until the reflected light from the object is detected by multiple photodetectors. The control unit acquires the multiple depth values ​​derived by the distance measuring device, derives an index value relating to the magnitude of variation of the multiple target depth values ​​based on a plurality of target depth values ​​which are at least a part of the multiple depth values, determines the adjustment content of the light intensity based on the index value and a predetermined reference value, and controls the light source so that the light intensity changes according to the determined adjustment content.
