<p><P>PROBLEM TO BE SOLVED: To highly accurately correct a point designated on a display surface when a touch panel receives a touch input. <P>SOLUTION: The touch panel display 108 includes: a conversion part 12 for converting a signal corresponding to a touch position to a coordinate value for the display surface; and a first calculation part 13 for calculating, on receipt of the touch input with a reference point as a target, a difference between a coordinate value of the reference point and the coordinate value obtained by converting the signal detected by the touch input. The first calculation part 13 calculates a first difference in a first state and a second difference in a second state. Furthermore, the touch panel display 108 includes: a second calculation part 14 for calculating a third difference in a third state and a fourth difference in a fourth state on the basis of the first difference and the second difference; and a correction part 16 which uses one of the first difference, the second difference, the third difference, and the fourth difference to correct the converted coordinate value. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
