Abstract

Detection accuracy of an indicator is improved. In a touch panel system 1 for, when an input position is indicated to a touch panel 3, displaying corresponding thereto, a detection standard determining section 615 within a controller section 6 comprises a strength correcting section 615F, which performs strength-correction on a capacitance property of height information z, which periodically varies with regard to at least either of the x or y direction of a detection surface (x, y), to a uniform capacitance property, with regard to distribution of three-dimensional coordinates (x, y, z) including height information z of a capacitance value that periodically varies for each predetermined position within the detection surface (x, y) obtained from respective output signals of the touch panel 3.
