Abstract
Provided is a touch panel system capable of reliably removing a wide variety of noises. The touch panel system () includes a subtracting section () which receives output signals from the sense lines () and finds differences between the capacitances in a direction in which each of drive lines () extends, as the differences in signal between the respective pairs of the sense lines () adjacent to each other. The subtracting section () obtains a difference signal value between the sense lines adjacent to each other.
