Abstract:
1. A touch input processor, comprising: a touch coordinate acquisition unit configured to acquire the coordinate position of a touch point on a touch panel; an area determination unit configured to determine whether or not the coordinate position of a touch point is present within an enlarging operation area on the touch panel, part of the touch panel being defined as the enlarging operation area used to operate the whole area of the touch panel; a drag determination unit configured to determine if a touch point has been dragged; an operation mode switching unit configured to switch, when the coordinate position of a touch point is present within the enlarging operation area and the touch point has been dragged, the operation mode for touch input from a normal operation mode to an enlarging operation mode; and a touch coordinate transformation unit configured to transform, when the operation mode is switched to the enlarging operation mode, the coordinates of an actual touch point within the enlarging operation area into the coordinates of a virtual touch point for an entire area of the touch panel.
