TOUCH PANEL INPUT DEVICE

摘要

Touch panel input device including: display panel having display surface; display controller causing display of button image on the display surface, the button image used for receiving touch operation performed by user; touch position detector detecting touch position of the display surface by detecting X and Y coordinates on X-Y rectangular coordinate system; area specifier specifying first area and second area of the display surface, the first area being area at which the button image is to be displayed, the second area being remaining area of display surface; and detection instructor referring to result of the specification by the area specifier and instructing the touch position detector (i) to perform touch position detection with respect to an area corresponding to the first area and (ii) to put in off state touch position detection with respect to an area corresponding to at least a part of the second area.

主权项

1. A touch panel input device comprising:
a display panel that has a display surface; a display controller that causes a button image to be displayed on the display surface, the button image used for receiving a touch operation performed by a user of the touch panel input device; a touch position detector that performs touch position detection of detecting a touch position of the display surface by detecting a set of an X coordinate and a Y coordinate on an X-Y rectangular coordinate system defined on the display surface; an area specifier that, when the button image is to be displayed on the display surface, specifies a first area and a second area of the display surface, the first area being an area of the display surface at which the button image is to be displayed, the second area being a remaining area of the display surface; and a detection instructor that refers to a result of the specification by the area specifier and provides an instruction to the touch position detector (i) to perform the touch position detection with respect to an area, on the rectangular coordinate system, corresponding to the first area and (ii) to put in off state the touch position detection with respect to an area, on the rectangular coordinate system, corresponding to at least a part of the second area.
