1. A method of distinguishing a plurality of objects on a touch panel, comprising:
- scanning the touch panel to obtain a plurality of positions corresponding to the objects on the touch panel and a plurality of induced capacitance signals corresponding to the positions;
identifying a plurality of maximum induced capacitance signals corresponding to the objects respectively; and
distinguishing the objects by referring to induced capacitance signal distributions around the maximum induced capacitance signals.
