<p>Provided are a touch panel system that can accept a touch panel operation by a user even in a situation where a noise is generated due to attachment of liquid or the like, by accurately distinguishing a position erroneously detected due to the noise and a position of an indicator, an electronic information device equipped with the touch panel system, and a touch panel system operation method. A touch panel system (1) is provided with: a touch panel (10); a drive line driving unit (20); a sense signal processing unit (30); and an indicator position detection unit (40). The indicator position detection unit (40) detects the indicator position while eliminating, from selection candidate positions corresponding to a signal value exceeding a first threshold value (Th1), a non-indicator position which is an elimination candidate position corresponding to a signal value greater than the first threshold value (Th1) and not greater than a second threshold value (Th2) and which is a position such that another elimination candidate position is present in a surrounding first range.</p> |
