There is provided a wireless sensor device capable of suppressing a reduction in detection sensitivity even if the distance between the wireless sensor device and a detection target is changed. A wireless sensor device 1 includes: a sensor unit 10 that generates a detection signal based on a transmission signal emitted to a detection target 30 and a reflection signal from the detection target of the transmission signal; and a signal processing unit 20 that performs signal processing on the detection signal generated by the sensor unit 10 . The sensor unit 10 generates a first detection signal Sa1 corresponding to a first phase state, which is a phase state of the transmission signal or the reflection signal, and a second detection signal Sa2 corresponding to a second phase state in which a phase of the transmission signal or the reflection signal is different from that in the first phase state. The signal processing unit 20 detects phase information based on the first detection signal Sa1 and second detection signal Sa2, and performs predetermined signal processing based on the detected phase information.

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.

In a magnetic field equilibrium type current detection device which uses a feedback coil, a planar pattern of the feedback coil is formed to enhance a measurement capability. A feedback coil 20 includes an element facing portion 20a and a parallel portion 20b. When a current magnetic field H0 is induced by a measurement current I0 and is applied to a magnetic detection element 10, a current is applied to the feedback coil 20 according to a detection output of the magnetic detection element 10, and a cancellation magnetic field Hd is induced by the element facing portion 20a. When the current magnetic field H0 and the cancellation magnetic field Hd enter an equilibrium state, the current flowing through the feedback coil 20 becomes a current measurement value. By setting a width dimension L of a coil line 21 of the element facing portion 20a to be smaller than that in the facing portion 20b, the cancellation magnetic field Hd is increased.

An input device capable of reducing an error generated in a result of detection of coordinates of an object due to an influence of noise or the like is provided. Evaluation values (E1 to E3) regarding the change in velocity of an object at coordinates of a detection surface indicated by individual coordinate data 32 are calculated on the basis of a series of coordinate data 32 of the same object, and it is determined whether or not there is an error in each coordinate data 32 on the basis of the evaluation values (E1 to E3). Therefore, in a case in which an extreme change in velocity of the object apparently occurs due to the influence of noise or the like, it is possible to accurately determine the error of the coordinate data 32 on the basis of the evaluation values (E1 to E3). Further, since the coordinate data 32 in which it is determined that there is an error in time-series of coordinate data 32 of the same object is corrected with data indicating the same coordinates P as that of coordinate data 32 immediately before such coordinate data 32, the error of the detection result of the coordinates generated by the influence of noise or the like can be effectively reduced.
