<p>PURPOSE:To simplify the operations of the input of an absolute coordinate value and that of a relative coordinate value by displaying a cursor, etc., corresponding to the absolute coordinate value when an inputted last absolute coordinate value is equal to the coordinate value held at a coordinate register, and to the coordinate value on which difference between the absolute values last time and this time is added when the former is different from the latter. CONSTITUTION:An input part 1 to which the absolute coordinate value is inputted, and the coordinate register 5 which stores the absolute coordinate value or adds and stores the difference inputted from the input part are provided, and a substitution part 4 stores the absolute coordinate value in the coordinate register 5 when the last absolute coordinate value inputted from the input part 1 is equal to the coordinate value stored in the coordinate register 5. Meanwhile, when they are different, the difference of the absolute coordinate values last time and this time is added, and is stored in the coordinate register 5. And the cursor, etc., is displayed on the position of a picture corresponding to the coordinate value stored in the coordinate register 5. Thereby, it is possible to easily perform the input operations for the absolute coordinate value and the relative coordinate value only by a tablet device, etc.</p> |
