Abstract: An input apparatus includes a casing having an operation surface, an opposite surface, a side surface, and an inner space, a substrate disposed along the opposite surface in the inner space, a top-surface-operation detecting unit including a first electrode pattern on the upper surface of the substrate, the top-surface-operation detecting unit detecting a change in electrostatic capacitance of the first electrode pattern caused by capacitive coupling to an operating body that comes close to or into contact with the operation surface, a side-surface-operation detecting unit on the side surface of the substrate, below the top-surface-operation detecting unit, the side-surface-operation detecting unit detecting a change in electrostatic capacitance caused according to a side surface operation performed on the side surface of the casing by the operating body, and a control unit that outputs an operation signal based on detection results of the top-surface-operation detecting unit and the side-surface-operation de

Abstract: A series of degree-of-approach data of the same object generated over a plurality of cycles of a detection operation is averaged in filter processing of the filter processing unit, and accordingly, the degree-of-approach data after averaging is acquired. Therefore, even in a case in which the degree-of-approach data is temporarily greatly changed due to an influence of noise, such a temporary change in the degree-of-approach data after averaging is suppressed. Further, response characteristics of a filter in the filter processing of the filter unit are changed according to a noise level which is detected by a noise detection unit. Accordingly, since appropriate filter processing according to the noise level is performed on the degree-of-approach data, the degree-of-approach data in which the influence of noise is effectively reduced is obtained.
