ABSTRACT:
There is provided a coordinate input device in which when a coordinate input object is moved on a tablet while being in contact with the tablet, and this state is displayed with cursor movement, fine movement or delay movement of the cursor does not occur. The coordinate input device is constituted by a tablet operated by a coordinate input object and a coordinate data generation section for generating coordinate data representing a coordinate position on the tablet operated by the coordinate input object, and the coordinate data generation section comprises a moving speed detection section for detecting a contact moving speed of the coordinate input object on the tablet and a fine movement removing filter for removing an unnecessary frequency component included in the coordinate data, so that a cutoff frequency of the fine movement removing filter is switched in accordance with the moving speed detected by the moving speed detection section.
