Abstract
An input device has: a detecting unit that generates a detection signal that changes according to the degree of the proximity of an object; a deciding unit that decides, according to a series of detection signals, whether a change due to the proximity of the object has occurred in the detection signals; and a reference value updating unit that, if the deciding unit decides that a change due to the proximity of the object has not occurred in the detection signals, updates a reference value, according to the detection signals. The deciding unit changes a decision reference so that the higher the degree, indicated by the difference between the reference value and the value of the detection signal, of the proximity of the object, is, the more likely the deciding unit is to decide that a change due to the proximity of the object has occurred in the detection signals.
