Abstract

An input device capable of preventing information according to a state of approach of an object to a detection surface from being input incorrectly due to an influence of noise is provided. A series of degree-of-approach data (33) of the same object generated over a plurality of cycles of a detection operation is averaged in filter processing of the filter processing unit (26), and accordingly, the degree-of-approach data (33) after averaging is acquired. Therefore, even in a case in which the degree-of-approach data (33) is temporarily greatly changed due to an influence of noise, such a temporary change in the degree-of-approach data (33) after averaging is suppressed. Further, response characteristics of a filter in the filter processing of the filter unit (26) are changed according to a noise level 35 which is detected by a noise detection unit (25). Accordingly, since appropriate filter processing according to the noise level 35 is performed on the degree-of-approach data (33), the degree-of-approach data (33) in which the influence of noise is effectively reduced is obtained.
