A touch panel controller (1) is provided with: a first capacitance distribution calculation unit (15) that outputs a first signal value map indicating the distribution of signal values in a touch panel (10); and a first capacitance distribution correction unit (16) that sets a wider area in the first signal value map than the area in which there is a change in a signal value caused by an input operation to the touch panel and performs correction calculation in that area to cancel out the change in the signal value caused by an external factor other than the input operation to the touch panel to generate a second signal value map. |
