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.

The lens module is provided in a receiving space defined in the casing. The positioning structure, which is connected between the lens module and the casing, is configured to limit the lens module within the receiving space and generate a frictional force. The electromagnetic driving module is provided in the receiving space and corresponds in position to the lens module. When supplied with electricity, the electromagnetic driving module generates a magnetic force that drives the lens module to move along a central axis. Once the electricity is cut off, the lens module is fixed in position and prevented from moving freely by the frictional force of the positioning structure; hence, the electromagnetic lens driving features economical use of electricity.

Abstract: A method is disclosed for determining a side-etching distance to compensate for the width of a wire to be formed on a printed circuit board. The wire is formed on a test board by etching off the copper foil on the test board with a film having the pattern of the wire. The wire is measured to find its resistance. The side-etching distance is obtained based on the formula: W=[(&rgr;/t)×L]×(1/R)±&sgr;, where W is the width of the wire, &rgr; is the resistance coefficient of the copper foil, t is the thickness of the copper foil, L is the length of the wire, and &sgr; is the side-etching distance.
