Claim:
1. A background signal processing method, which is used in a sensor device having a plurality of conductive wires and a predetermined background signal threshold, the background signal processing method comprising the following steps of: (1) detecting a first background signal measurement value of a first conductive wire group in the conductive wires according to a first conductive wire number interval, beginning from an n (2) determining whether the first background signal measurement value complies with the predetermined background signal threshold, if yes, stopping in this step, otherwise proceeding to step (3); (3) selecting a corresponding second conductive wire number interval according to the first background signal measurement data; (4) detecting a second background signal measurement value of a second conductive wire group in the conductive wires according to the second conductive wire number interval, beginning from an (n+m) (5) calculating a background signal speculating value of a third conductive wire group in the conductive wires according to the first background signal measurement value and the second background signal measurement value, wherein the third conductive wire group is derived by excluding the first conductive wire group and the second conductive wire group.
