A mark (something like a reflecting tape which reflects light in the coaxial direction when the light is applied, or an infrared radiant) attached on an object is caught with the coaxial light (visible radiation, infrared light) by a TV camera or infrared TV camera, and video signals from the camera are processed in binary in an image processing apparatus. Consequently, a high luminous mark appears on a binary image, and the primary moment center values (so called 'centroid') on the high luminous binary image are calculated on real time, for instance, every 1/60 second, and fed back to an electrically-powered driving part of a lighting unit, so that the lighting is always applied to the position. An electrically-powered turn table automatically operates the control of the lighting directions by the signals feed backed. By carrying out a series of controls precisely as mentioned above, the lighting can be applied by the lighting unit tracking automatically the position of the moving mark. The operability of a lighting unit regarded as a serious problem for an operator usually operating many lighting units can be improved to allow an effective lighting operation.
