TOUCH-PANEL DEVICE
First Claim
1. A touch-panel device for detecting a touched position based on sensor measured values determined by a plurality of sensors, the touch-panel device being configured to:
- determine, based on the sensor measured values for detecting a touched position in an X direction and a touched position in a Y direction, a width in the X direction and a width in the Y direction of an area where a touched area and an electrode area overlap each other;
determine, based on the width in the X direction and the width in the Y direction, a position of a center of the touched area; and
calculate the position of the center as the touched position.

Abstract
Provided is a touch-panel device capable of detecting a touched position with high accuracy even when a touched area extends off an electrode area. According to the present invention, the touched area is assumed to be, for example, a circular in shape. A width in an X direction (overlap width (X46)) and a width in a Y direction (overlap width (Y47)) of an area where the touched area in a circular shape and an electrode area (6) overlap each other may be determined based on sensor measured values. When the overlap width (X46) and the overlap width (Y47) are different from each other, it is judged that the touched area extends off the electrode area, and a position of a center of the touched area in the circular shape is calculated as the touched position.

6. A touch-panel device for detecting a touched position based on sensor measured values determined by a plurality of sensors and on positions of the plurality of sensors,
the touch-panel device being configured to perform a coordinate calculation process by using parameter values for the positions of the plurality of sensors, the parameter values employed in a case where a periphery of a touch panel is touched being different from parameter values employed when a center of the touch panel is touched.
