Mobile terminal apparatus

摘要

A terminal apparatus that includes a touch panel; a proximity detection unit configured to detect an approach and contact of an external object to the touch panel based on a changed in capacitance value and to detect a location on a surface of the touch panel where the capacitance value changed; and an operation control unit configured to control the proximity detection unit to stop the detection of a location contacted by the external object on the touch panel surface when the approach of the external object is detected by the proximity detection unit.

1. A terminal apparatus comprising:
a touch panel that is integrated with a display; a proximity detector configured to detect an approach and contact of an external object to the touch panel based on a changed in capacitance value and to detect a location on a surface of the touch panel where the capacitance value changed; and an operation controller configured to stop the detection of a location contacted by the external object on the touch panel surface when the approach of the external object is detected by the proximity detector, wherein the operation controller measures a size of an area where the capacitance value has changed and detects a capacitance detection level in the area, and controls the proximity detector to stop the detection of a location contacted by the external object on the touch panel surface when the measured size of the area is equal to or greater than a predetermined size and the capacitance detection level is greater than a first predetermined threshold and less than a second predetermined threshold, wherein the terminal apparatus further comprises a non-contact communicator configured to perform an electronic payment transaction with an external non-contact communication reader/writer, wherein the proximity detector starts detecting the approach and contact of the external object to the touch panel when an electronic payment application is started on the terminal apparatus in which the electronic payment transaction is performed, and while performing the electronic payment transaction with the external non-contact communication reader/writer, the operational controller is configured to control display of a message on a portion of the display that is determined to be unobstructed by the external object.
