Carmera focusing method for image communication terminal

PURPOSE: An automatic object tracking method for visual communication terminal is provided to recognize an object using a contour extractor and a temperature sensor and to automatically track the position of the object when position information of the object is changed. CONSTITUTION: A contour extractor obtains the contour of an object inputted through a camera. The figure of a user is recognized using a non-contact type infrared temperature sensor from the extracted contour(S12,S13). The camera is moved in four directions according to the motion of the object(S14). The camera is included in a visual communication terminal or attached to the outside of the terminal. The camera controls a focus of a lens to receive the object and stores the object in a memory. The visual communication terminal extracts the contour of the object stored in the memory using the contour extractor.
