<p>PROBLEM TO BE SOLVED: To rightly correct the position coordinates of display contents displayed on a display screen. SOLUTION: The position coordinates of coordinate information to be displayed on the display screen are corrected by a controller while using a correction system for making the position coordinates of a reference point agree with detected coordinates without making the position coordinates of the reference point after correction get out of a coordinate input/detection area. Thus, when an adjusting person is to touch the reference point, even when a position away from the reference point is erroneously touched, an uncorrectable value can be prevented from being generated when performing the position correction again. Thus, by performing the position correction again, the position coordinates of the display contents displayed on the display screen can be rightly corrected.</p> |
