Coordinate input apparatus, control method thereof, and program |
摘要 |
A signal change range generated by a pointing operation of a pointer on a coordinate input region is specified in correspondence with the initial detection signal distribution of a detection unit in an initial state without pointing on the coordinate input region. Pieces of end information of the specified signal change range are detected. The validity of a detection state in the end information detection step is determined by using the plurality of pieces of detected end information. On the basis of the determination result, the coordinates of the point position of the pointer are calculated from the plurality of pieces of end information.
