<p>PURPOSE: A method for operating a touch of a touch screen with a camera is provided to obtain information about an unclear touch point by a correction algorithm. CONSTITUTION: A touch screen system initially sets a touch screen. The system checks a touch through a white and black image which is captured by camera sensors(L1,C1,C2,R1) in real time. The system scans an image by a camera sensor which is close to a touch point. When a plurality of touch points are obtained, the system extracts a real touch point. The system corrects a coordinate of the extracted touch point.</p> |
