1. A multi-touch control method, comprising:
- sensing a plurality of sensing values associated with a touch panel;
providing a threshold;
identifying two peak sensing values from the plurality of sensing values;
comparing each of the sensing values located between the two peak sensing values with the threshold to generate a comparison result; and
selectively reporting a multi-touch event according to the comparison result,wherein no multi-touch event is reported when the sensing values between the two peak sensing values are not lower than the threshold, andwherein the multi-touch event corresponding to the two peak sensing values is reported when at least one of the sensing values between the two peak sensing values is lower than the threshold.

Abstract
A method for multi-touch control and associated apparatus is provided. The method includes indentifying two peak sensing values from a plurality of sensing values of a touch panel, providing a threshold according to intrinsic characteristics of the touch panel and features of the sensing values, comparing whether the sensing values between the two peak sensing values are lower than the threshold, and selectively reporting multi-touch events.

14. A multi-touch control apparatus, coupled to a touch panel, comprising:
-
a peak value identification module, for receiving a plurality of sensing values sensed by the touch panel, and identifying two peak sensing values from the sensing values; a comparison module, for comparing each of the sensing values located between the two peak sensing values with a threshold to generate a comparison result; and a reporting module, for selectively reporting a multi-touch event according to the comparison result, wherein the reporting module reports no multi-touch event when the comparison module determines by comparison that the sensing values between the two peak sensing values are not lower than the threshold, and wherein the reporting module reports the multi-touch event, which corresponds to the two peak sensing values, when the comparison module determines by comparison that at least one of the sensing values between the two peak sensing values is lower than the threshold. - View Dependent Claims (15, 16)
