Abstract
Provided is a touch panel system () capable of reliably removing a wide variety of noises. The touch panel system () includes a main sensor () which detects a touch operation, a sub sensor () which does not detect a touch operation but detects a noise component, and a subtracting section () which subtracts, from an output signal of the main sensor (), an output signal of the sub sensor (). The subtracting section () performs a subtracting operation to remove a noise component from the output signal of the main sensor (), thereby extracting a signal derived from the touch operation itself.
