Abstract
A sensor unit outputs detection data as the detection result of the approach state of an object at a plurality of detection positions. A noise amount calculation unit calculates noise included in the detection data as the amount of noise. Then, when a filter unit attenuates the noise included in the detection data, the noise attenuation characteristics of a low-pass filtering process are changed depending on the calculated amount of noise such that the attenuation of noise increases as the amount of noise increases and decreases as the amount of noise decreases.
