Apparatus and system for correcting touch signal and method thereof
An apparatus and a system for correcting touch signal and a method thereof are provided. The method includes the following steps. A beam is emitted to obtain a detective beam by reflecting the beam with a reflective element, and a detective signal distribution graph is generated. A plurality of intersections, a covered region and a pixel position corresponding to the covered region are obtained according to the detective signal distribution graph and a threshold value distribution graph. A first area occupied by the covered region is calculated according to the detective signal distribution graph and the plurality of intersections. Whether an overexposure is occurred in the covered region is determined according to the first area corresponding to the covered region. If the overexposure is occurred in the covered region, the covered region being overexposed and the pixel position corresponding to the covered region being overexposed are corrected.
