Target tracking device

Abstract

Abstract PURPOSE:To surely trace an object by continuously detecting a position of an object in a picture so as to control panning or tilt of a television camera depending on the detected position of the object thereby extracting a characteristic quantity in matching with a delicate color difference and color change. CONSTITUTION:When a picture with luminance Y, hue H and saturation S is stored in a picture memory 12, an interrupt signal INT is outputted from a memory control block 13 by a microcomputer 14. A characteristic quantity of a tracking object is extracted by setting an object in existence in the middle of the screen when a switch 16 of a panning/tilt device 15 is pushed. The position of the object is detected based on the set characteristic quantity and the picture in the picture memory 12 and the result of detection is outputted to a motor of the panning/tilt device 15 to drive a television camera 10. Then updating of picture data in the picture memory 12, position detection by the microcomputer 14 and control of the television camera 10 are repeated.
