Claim Text:
1. A signal processing method for a touch panel, the touch panel comprising a first sensing region and a second sensing region, the first sensing region being monitored by at least one sensor to generate a first monitoring result, the second sensing region being monitored by at least one sensor to generate a second monitoring result, wherein the first monitoring result comprising a plurality of first sub-results and the second monitoring result comprising a plurality of second sub-result, the signal processing method comprising: grouping the first sub-results to generate a first grouping result; grouping the second sub-results to generate a second grouping result; determining that the first sensing change group forms the touch point in the first sensing region when the first group result indicates that a first sensing change group occurs in the first sensing region and the second grouping result indicates that no sensing change group occurs in the second sensing region; determining a distance between the first sensing change group and the second sensing change group when the first group indicates that the first sensing change group occurs in the first sensing region and the second grouping result indicates that a second sensing change group occurs in the second sensing region; determining that the first sensing change group forms the touch point in the first sensing region and the second sensing change group forms another touch point in the second sensing region when the distance is greater than a threshold; collectively regarding the first sensing change group and the second sensing change group as an intermediate touch point, and generating position information of the intermediate touch point according to the first monitoring result and the second monitoring result when the distance is smaller than the threshold; and performing step (a) and step (b) for the touch point:
