Abstract
A signal change range, which is generated due to a pointing operation of a pointer on a coordinate input region, with respect to an initial detection signal distribution of a detection unit in an initial state in which no pointing operation is made on the coordinate input region, is specified. End portion information of the specified signal change range is detected. Coordinates of the pointed position of the pointer are calculated using at least one of a plurality of pieces of detected end portion information.
