<p>PROBLEM TO BE SOLVED: To provide an inexpensive system for automatically following a moving illuminated subject by means of a plurality of lighting devices by detecting the position or moving dimension of the moving illuminated subject with a simple system composition. SOLUTION: This system is provided with a lighting device 1 having a driving shaft for rotating an illuminated subject in vertical and horizontal directions, following movement of the illuminated subject; a CCD video camera 2 fixedly disposed in a following range of the moving illuminated subject or built in the lighting device 1; a control device 4 for the CCD video camera 2 for specifying a position of the illuminated subject moved from an image data imaged at a constant cycle by the CCD video camera 2; and a master controller 3 formed in such constitution that a position information specified by the control device 4 is taken in at a constant cycle through a communication line, a present position of the illuminated subject moved from the positioning information is dicided, the illuminating direction of the lighting device 1 is operated by remote control so as to face to the moving illuminated subject.</p> |
