Abstract
A method of detecting power of an active touch medium is disclosed in the present invention. The method includes capturing an image with an optical signal generated from the active touch medium, reading a first threshold value, comparing an intensity of the optical signal and the first threshold value, and executing a low power mode when the intensity of the optical signal is smaller than the first threshold value.
