Claim:
1. A background signal processing method, which is used in a sensor device having a plurality of conductive wires and a plurality of predetermined background signal thresholds and background base signal values, 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 a predetermined first background signal threshold, if yes, stopping in this step, otherwise, proceeding to step (3); (3) determining whether the first background signal measurement value complies with a predetermined second background signal threshold, if yes, proceeding to step (4), otherwise, proceeding to step (5); (4) updating a background signal; (5) detecting a second background signal measurement value of a second conductive wire group in the conductive wires according to the first conductive wire number interval, beginning from an (n+m) (6) 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.
