1. A touch panel device, comprising:
- a touch panel configured to detect a touch input, the touch panel including a plurality of electrodes; and
circuitry configured to;
determine a detection range of an object approaching the touch panel based on an output distribution of capacitance values from the touch panel, the detection range being within a surface area of the touch panel;
determine a first length of the detection range, the first length being a length of the detection range on an edge of the touch panel where the detection range of the object and the edge of the touch panel intersect;
determine a second length of the detection range, the second length being a length of the detection range in a direction substantially parallel to the edge of the touch panel within the surface area of the touch panel;
compare the first length with the second length; and
determine an input operation corresponding to the object to be invalid in response to determining that the first length is equal to or larger than the second length.

Abstract
A touch panel device that detects a touch input at a touch panel including a plurality of electrodes arrayed in X and Y directions, calculates a width corresponding an object approaching the touch panel based on an output distribution of capacitance values from the touch panel, and determines whether an input operation corresponding to the object is valid based on the calculated width of the object.
