Abstract
Provided are a touch panel system with improved indicator detection accuracy and an electronic information device provided with the touch panel system. A touch panel systemincludes: a touch panelprovided with a plurality of electrodes SL, DL; and an indicator position detection unitfor detecting a position of the indicator that is in contact with or close to the detection surface P, based on an output signal that is outputted by at least part of the electrodes SL, DL and shows a capacitance formed by the electrode SL. The touch panel system is characterized in that the indicator position detection unitcorrects detection sensitivity for each predetermined position within the detection surface P so as to correspond to a pattern of the electrodes SL, DL, and detects the position of the indicator within the detection surface P.
