OPTICAL TOUCH-CONTROL SYSTEM WITH TRACK DETECTING FUNCTION AND METHOD THEREOF
First Claim
1. An optical touch-control system processing track detection for moving an objective within a display panel according to a detected track, the optical touch-control system comprising:
- a light source for emitting a specific light;
a sensing array for continuously sampling the specific light reflected by an instruction object in a predetermined period, to accordingly generate a first image signal related to a first sensing image signal and a second image signal related to a second sensing image signal; and
a motion detector for outputting a motion vector signal to determine the track of the instruction object according to the first sensing image signal and the second sensing image signal;
wherein the instruction object moves within a first zone of the sensing array.
