发明名称 COORDINATE INPUT DEVICE AND CONTROL METHOD AND PROGRAM THEREFOR
摘要 <p><P>PROBLEM TO BE SOLVED: To detect a plurality of instruction inputs without reducing input and output response speed as much as possible and accurately calculate position coordinates to the instruction inputs. <P>SOLUTION: Of a plurality of detection means detecting presence/absence of an instructing tool onto a coordinate input area, end information for both ends is selected from a plurality of pieces of end information of signal change range in the first detection means and a plurality of pieces of end information of signal change range in the second detection means, and coordinates of instruction positions of the plurality of instruction tools are calculated using the end information in the first detection means and the second detection means. <P>COPYRIGHT: (C)2007,JPO&INPIT</p>
