<p>PROBLEM TO BE SOLVED: To provide a coordinate detector with which more suitable coordinate detection can be performed by adopting a method of reference value setting even in the case of 8-wire type digitizer and a user can perform coordinate detection based on the method of reference value setting even without performing operation for pressing a prescribed position every time. SOLUTION: Fist of all, reference value setting controls (S19-S24) for providing a potential gradient straight line by letting the user press a preset display point and terminal potential detecting controls (S12-S14) for providing a potential gradient straight line by detecting a terminal potential are performed and when the terminal potential is fluctuated, the coefficient of the potential gradient straight line provided by reference value setting control is corrected (S16 and S17).</p> |
