Abstract
There is provided a sensor unit for detecting a proximity state of an object at N detection positions, generating a composite detection signal in conformity with the sum of N detection signals obtained as a result of detection for N detection positions, and controlling a positive or negative polarity of the detection signal having a signal level in conformity with the proximity state at each of N detection positions, a sensor control unit for controlling the sensor unit for generating M composite detection signals having N polarity patterns set at N detection signals different from each other, and a signal regeneration unit for regenerating the signal level of the N detection signal based on the M composite detection signals generated by the sensor unit.
