Abstract: An input device includes a sensor unit, a processing unit, a storage unit, and an interface unit. The processing unit includes: a change amount calculating section for calculating the temporal change amount of the electrostatic capacitance that is detected by the sensor unit and that changes according to the proximity degree of an object with respect to a detection surface; a determination section for determining a touch operation corresponding to an operation on the detection surface using a fingertip, a palm operation corresponding to an operation on the detection surface using a palm, and a grip operation corresponding to an operation on a conductor portion, based on the calculated change amount; and a reset section for performing reset processing in a case where the duration of a state, in which a palm operation is not determined and a grip operation is determined, is a first predetermined time or more.

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.
Abstract translation: 在滤波处理单元的滤波处理中对在检测操作的多个周期中生成的同一对象的一系列进近程度数据进行平均，从而获取平均后的接近度数据。 因此，即使由于噪声的影响而临时大幅度地改变接近数据的情况，抑制了平均化后的接近数据的临时变化。 此外，滤波器单元的滤波处理中的滤波器的响应特性根据由噪声检测单元检测到的噪声电平而改变。 因此，由于对接近度数据执行根据噪声电平的适当的滤波处理，因此获得有效降低噪声影响的接近程度数据。

Abstract: An input apparatus includes a plurality of electrodes spaced apart from each other, a signal processing unit configured to output an input signal depending on a change in a capacitance of each electrode, and a determination unit configured to determine whether an operation object comes in a proximity of at least one of electrodes based on input signals output from the signal processing unit. The determination unit makes a determination such that in a case where one of the input signals is greater than or equal to a first threshold value and an integral value of another of the plurality of input signals in a predetermined integration period is greater than or equal to a second threshold value, it is determined that an operation object has come in a proximity of an electrode corresponding to the one of the input signals.
