Abstract
A touch system is disclosed herein. The touch system includes detecting units and a control unit. The detecting units are disposed around a detecting area, and form a plurality of scan lines therebetween. The control unit is configured to detect first crossing points according to a transmission status of each of the scan lines, to delete ghost points of the first crossing points according to a first scan line having a first slope value of the scan lines to generate second crossing points, and to divide the second crossing points into groups to output touch points.
