Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To make it possible to distinguish whether a touch panel is touched with a finger or a rod body and determine, even when the touch panel is strongly touched with the rod body, whether or not a pointer is the rod body.SOLUTION: A touch panel controller (10) includes a peak value detection circuit (135) for detecting a peak value on a touch panel (20), a finger threshold filter (140) for determining based on a finger threshold, a finger peripheral threshold filter (145) for determining based on a finger peripheral threshold, a rod body threshold filter (150) for determining based on a rod body threshold, and a rod body peripheral threshold filter (155) for determining based on a rod body peripheral threshold.SELECTED DRAWING: Figure 1
