Abstract:
A pointed position on a coordinate input region is detected, and the coordinates of the pointed position are calculated. A region on the coordinate input region, to which the calculated coordinates belong, is determined. Pen-down information corresponding to the pointed position is generated on the basis of the determined region to which the coordinates belong.
