<p><P>PROBLEM TO BE SOLVED: To provide a coordinate detection device capable of easily calculating an appropriate correction value and thus reducing the time of a coordinate detection process, a display device using it, and a coordinate detection method. <P>SOLUTION: The coordinate detection device is provided with a reference point display instruction part 11a for instructing a display device to display five reference points on a display screen during a calibration process, and a correction value calculating part 11b for calculating, for each of the five reference points, an amount of difference between an instructed coordinate detected by an instructed coordinate detecting part 10a and the display coordinate of the reference point corresponding to the instructed coordinate, and calculating a correction value for correcting an amount of difference between the instructed coordinate and a display coordinate corresponding to the instructed coordinate. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
