Abstract:
1. A method, comprising: determining a first plurality baseline capacitance values of a capacitive touch panel corresponding to a first frequency; capturing in rapid succession, a first frequency frame scan of the capacitive touch panel at the first frequency and a second frequency frame scan of the capacitive touch panel at a second frequency; calculating differences in capacitance values of the capacitive touch panel between the first frequency frame scan and the second frequency frame scan; repeating, for a predetermined number of times: determining average differences in capacitance values of the capacitive touch panel between the first frequency frame scans and the second frequency frame scans; and generating a second plurality of baseline capacitance values of the capacitive touch screen corresponding to the second frequency by adding the determined average differences in capacitance values of the capacitive touch panel to the first plurality of baseline capacitance values of the capacitive touch screen corresponding to the first frequency.
