<p><P>PROBLEM TO BE SOLVED: To easily correct one of input values required to be corrected out of a first input value and a second input value. <P>SOLUTION: The input value supplied to a CPU 5 for calculating coordinates from a touch panel 1 is supplied to a correction means 12 and corrected to a correct value after being transformed into the coordinates by a coordinate calculation means 11. The input value supplied to the CPU 5 from an electromagnetic type sensor 2 is supplied to a coordinate calculation means 13 to be transformed into highly precise coordinates. Signals indicating the presence of inputs from the coordinate calculation means 11 and the coordinate calculation means 13 are supplied further to a simultaneous determination means 14, and determination signals thereof are supplied to detect a difference between coordinates transformed based on the respective input values. A difference value is stored in a correction table 17 through a difference table 16, and the difference value is added or subtracted to/from a coordinate value supplied to a correction processing means 12 and calculated by the coordinate calculation means 11. A calculated coordinate value is selected by an output selecting means 18 taken out to a coordinate output 6. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
