Abstract
An input panel interface section is responsive to an input signal from an input panel to provide input coordinate data indicating an input position in a coordinate system used in the input panel. A converter converts the input coordinate data provided by the input panel interface section into display coordinate data. The display coordinate data is data in a coordinate system used for a display controller to determine a display position on a display. The display controller controls display output to the display by using the display coordinate data output by the coordinate converter. A CPU interface section controls access of a processor to the display controller, the input panel interface section, and the coordinate converter.
