1. A touch panel device comprising:
- a touch panel that detects a touch input, the touch panel including a plurality of electrodes arrayed in X and Y directions; and
circuitry configured tocalculate a first width corresponding an object approaching the touch panel based on an output distribution of capacitance values from the touch panel; and
determine whether an input operation corresponding to the object is valid based on the calculated first width of the object.

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.

19. A method performed by a touch panel device, the method comprising:
-
detecting a touch input at a touch panel including a plurality of electrodes arrayed in X and Y directions; calculating, by circuitry, a width corresponding an object approaching the touch panel based on an output distribution of capacitance values from the touch panel; and determining, by the circuitry, whether an input operation corresponding to the object is valid based on the calculated width of the object.

20. A non-transitory computer-readable medium including computer-program instructions, which when executed by a touch panel device, causes the touch panel device to perform a method comprising:
-
detecting a touch input at a touch panel including a plurality of electrodes arrayed in X and Y directions; calculating a width corresponding an object approaching the touch panel based on an output distribution of capacitance values from the touch panel; and determining whether an input operation corresponding to the object is valid based on the calculated width of the object.
