The present invention has increased detection precision of an indicator. Provided is a touch panel system (1) such that an input position is indicated to a touch panel (3) and a corresponding display is performed, wherein the touch panel system (1) has, in a detection baseline setting unit (615) within a controller (6), a strength correction unit (615F) that, with respect to the distribution of 3D coordinates (x, y, z) containing height information (z) of capacitance values that cyclically fluctuate for each predetermined position in a detection plane (x, y) obtained from each output signal of the touch panel (3), causes the strength correction to uniform capacitance characteristics of the capacitance characteristics of the height information (z) that cyclically fluctuates with respect to at least the x direction among the x direction and y direction of the detection plane (x, y). |
