Abstract
When at least one external object approaches or touches a touch sensor, profiles in a scanning signal corresponding to each external object will appear. The smallest value between the profiles corresponding to a first and a second external object is designated as a division value when the profiles corresponding to the first and the second external objects overlap. The overlapping profiles can be divided into the portion of the first external object and the portion of the second external object, respectively.
