Abstract
A coordinate input apparatus and a coordinate inputting method are provided, in which any influence on display images by coordinate information recorded on a coordinate plate can be extremely reduced and excellent operation of input indication is enabled without being disturbed by the coordinate information. A coordinate input apparatus includes a coordinate plate having plural pieces of coordinate information recorded thereon and a pen, or input-indicator, for indicating a desired position of the coordinate plate so as to detect coordinate information in the vicinity of the position and for indicating a position to be input. Coordinate values are determined from the coordinate information detected by the input-indicator so as to determine a coordinate value of the coordinate in the position to be input on the basis of the coordinate values and to input the coordinate value.
