Abstract
An auto-focus compensation method, adapted to an image capturing device having a touch screen, includes the following steps. First, a first touch operation performed on a first object displayed on the touch screen is detected. Next, an auto-focusing procedure is performed so as to obtain a focused image. A staying time of the first touch operation on the first object is accumulated and determined whether it exceeds a time threshold. When the staying time exceeds the time threshold, an adjustment interface is displayed on the touch screen, and a second touch operation performed on the adjustment interface is detected. The focused image is adjusted according to the second touch operation, and a new focused image is thus obtained and captured. An image capturing device is also provided in the invention to implement the aforementioned auto-focus compensation method.
