Baseline updating method and touch device

The invention provides a baseline updating method. The baseline updating method includes: detecting a first frame capacitance value; setting a baseline according to the first frame capacitance value; detecting a current capacitance value of a touch screen, and calculating a difference value between the capacitance value and the baseline; when the difference value between the capacitance value and the baseline is smaller than a negative noise threshold, starting a first timer for timing; if the difference values within a first time range are smaller than the negative noise threshold, updating the baseline according to the capacitance value to activate an extreme value recovery function of the baseline; judging whether the touch screen is touched or not according to the difference value between the current capacitance value and the updated baseline; and if judgment shows that the touch screen is touched, deactivating the extreme value recovery function of the baseline to enable the baseline not to be updated when the difference value between the current capacitance value and the updated baseline is smaller than the negative noise threshold again. By the aid of the baseline updating method in the embodiment, the touch screen is applicable to various operating environments while the operating speed of the touch screen is unaffected, and a certain waterproof effect can be achieved.
