Abstract
A touch coordinate acquisition unit acquires the coordinate position of a touch point on a touch panel. An area determination unit determines whether or not the coordinate position of a touch point is present within an enlarging operation area provided in part of the touch panel. A drag determination unit determines if a touch point has been dragged. When the coordinate position of a touch point is present within the enlarging operation area and the touch point has been dragged, an operation mode switching unit switches the operation mode for touch inputs from a normal operation mode to an enlarging operation mode. When the operation mode is switched to the enlarging operation mode, a touch coordinate transformation unit transforms the coordinates of an actual touch point within the enlarging operation area into the coordinates of a virtual touch point for the whole area of the touch panel.
