Automatic tracking lighting equipment for automatically tracking a target to be illuminated. A spotlight is supported for pivoting in horizontal and vertical directions on a ceiling surface. A horizontal drive mechanism changes the horizontal angle of the spotlight and a vertical drive mechanism changes the vertical angle of the spotlight. A CCD camera picks up the image of a target area to be illuminated. An image recognition unit processes the image from the CCD camera to recognize the target to be illuminated and to specify its coordinates. A coordinate calculation unit calculates how far to move the spotlight based on a distance of the target to be illuminated. A movable control unit converts the output of the coordinate calculation unit into drive signals for the horizontal drive mechanism and for the vertical drive mechanism and outputs drive signals to pivot the spotlight in a desired direction.

[ What is claimed is:] [1.] A lighting controller for a system including a lighting fixture for radiating light from a light source, a drive section for pivoting the lighting fixture around a pan axis and about a tilt axis, an image pickup means, pivotable around an axis, for picking up an image in an image pickup region and outputting an image, a display device which displays the image, and an input device for designating a point on the display image displayed on the display device, the lighting controller comprising:a pivoting quantity calculating section which calculates a first pivoting quantity about the pan axis of the lighting fixture for illuminating the designated point based upon a relative distance in a horizontal direction between the position on the display image designated by the input device and the position of origin of the display image, and which calculates a second pivoting quantity about the tilt axis of the lighting fixture for illuminating the designated point based upon a relative distance in a vertical direction between the position on the display image designated by the input device and the position of origin of the display image, whereby the drive section pivots the lighting fixture based on the first and second pivoting quantities.
