Abstract
A detecting method for a touch device, the method includes the steps of reading all sensed values of a frame associated with the touch device, computing a difference between a maximum sensed value and a minimum sensed value of all the sensed values of the frame, comparing the difference with a base value to generate a comparison result and executing a corresponding operation based on the comparison result.
Claims25
A detecting method for a touch device comprising steps of:
- reading all sensed values in a single frame;
- computing a difference between a maximum sensed value and a minimum sensed value of all the sensed values of the frame;
- comparing the difference with a base value to generate a comparison result;
- and
- executing a corresponding operation based on the comparison result.

A detecting method for a touch device, comprising steps of:
- defining a plurality of continuous time points;
- reading, at each of the plurality of continuous time points, all sensed values in a single frame corresponding to the time point;
- computing a difference between a maximum sensed value and a minimum sensed value of all the sensed values of each of the frames;
- comparing the difference with a base value to generate a comparison result;
- and
- executing a corresponding operation based on the comparison result.
