<P>PROBLEM TO BE SOLVED: To correct a coordinate deviation beyond the scope of normally assumed coordinate deviation while preventing calibration due to a user's erroneous operation, when calibrating a coordinate deviation. <P>SOLUTION: A system control circuit 101 being a display control apparatus transforms a touch input according to a transformation coefficient for transformation into coordinate on a display part 106 to obtain a detected coordinate. When a detected coordinate is obtained inside a first area defined in advance taking the target coordinate as a reference point, a system control circuit uses the detected coordinate as a calibration coordinate. When the detected coordinate is outside the first range, and the detected coordinate is obtained a predefined number of times and the relationship between the detected coordinates satisfies a specific condition defined in advance, the system control circuit takes the detected coordinate as the coordinate for calibration, and updates the transform coefficient according to the coordinate for these calibrations. <P>COPYRIGHT: (C)2011,JPO&INPIT |
