摘要：
An optical touch screen system includes a sensing device and a processing unit. The sensing device includes first and second sensors, each generating an image. The images include the image information of a plurality of objects. The processing unit generates a plurality of candidate coordinates according to the image information and selects a portion of the candidate coordinates as output coordinates according to an optical feature of the image information.
