Method For Determining The Number Of Fingers On A Sensing Device
First Claim
Patent Images
1. A method for determining the number of fingers on a sensing device that has a plurality of scanlines, said method comprising the steps of:
- A) scanning the scanlines;
B) identifying the scanlines scanned in step A) that generate a detecting signal, which has a value greater than a threshold value;
C) finding adjacent ones of the scanlines identified in step B);
D) forming at least one group from the adjacent ones of the scanlines found in step C); and
E) counting the number of the scanlines in the at least one group formed in step D) in order to determine the number of fingers on the sensing device.

Abstract
A method for determining the number of fingers on a sensing device, which has a plurality of scanlines, includes the steps of: identifying the scanlines that generate a detecting signal, which has a value greater than a threshold value; finding adjacent ones of the scanlines; forming at least one group from the adjacent ones of the scanlines thus found; and counting the number of the scanlines in the at least one group thus formed in order to determine the number of fingers on the sensing device.

7. A method for determining the number of fingers on a sensing device that has a plurality of first scanlines, and a plurality of second scanlines that intersect the first scanlines, said method comprising the steps of:
-
A) scanning the first and second scanlines; B) identifying the first and second scanlines scanned in step A) that generate a detecting signal, which has a value greater than a threshold value; C) finding adjacent ones of the first scanlines and adjacent ones of the second scanlines identified in step B); D) forming at least one first group from the adjacent ones of the first scanlines found in step C), and at least one second group from the adjacent ones of the second scanlines found in step C); E) when the number of the at least one first group is equal to the number of the at least one second group formed in step D), counting the number of the first scanlines in the at least one first group formed in step D) in order to determine the number of the fingers on the sensing device; F) when the number of the at least one first group is less than the number of the at least one second group formed in step D), counting the number of the first scanlines in the at least one first group formed in step D) in order to determine the number of the fingers on the sensing device; and G) when the number of the at least one second group is less than the number of the at least one first group formed in step D), counting the number of the second scanlines in the at least one second group formed in step D) in order to determine the number of the fingers on the sensing device. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
