POSITION INFORMATION INPUT DEVICE USING PRESSURE SENSITIVE TABLET

摘要

PURPOSE:To exclude wrong coordinate position information by deciding whether or not coordinate position information obtained by input operation by the depression of a pen, etc., is proper and determining the information when the information is a proper value. CONSTITUTION:The pressure sensitive tablet 11 outputs the coordinate position information corresponding to an input position on the input surface. A CPU 13 decides whether or not the coordinate position information which is currently inputted is a proper value on the basis of determined coordinate position information which is inputted before it, and outputs the information as determined coordinate position information when the information is the proper value or excludes the coordinate position information from the determined coordinate position information when not.
