Abstract: A method for reducing image noise is provided. The procedure of the method is provided in the following steps. First, the color level scale of a scanned image of a document is reduced by a plurality of bits in order to subtract a noise level from the scanned image. Then the color level scales of all pixels of the image are recombined by a halftone pattern method in order to recover the color level scales. Finally the missing codes of the image are filled out by bit enhance method. Because of the color level scales of the proceeding image are not reduced, the scanned image quality does not be blurred by the method. Because the method does not minimize the color level of the proceeding image, the image noise can be reduced without blurring the scanned image and the quality of the image can be increased after the process thereof. And because each color level of the pixel in the image is subtracted by a noise level, some of the bits are removed and the capacity of the image file is decreased.

Abstract: The present invention provides a method for removing micro-debris generated in a laser machining process operated on machined object and device of the same. The machined object is placed on a movable machining platform within a machining range and machined at a particular machining location. By disposing an acoustic wave generator and a reflector part, or by disposing a plurality of acoustic wave generators, at least two standing waves extending across the machining range and two standing wave nodes are generated. The micro-debris generated from the laser machining process is moved away by the standing waves to concentrate at the standing wave nodes, and subsequently removed from the standing wave nodes.
