Publication number: 20070247491Abstract: In an image forming method employing an inkjet technique, when a dot is formed by the use of a normal nozzle and an abnormal nozzle neighboring to the abnormal nozzle, binary data are corrected so as not to form the dot by the use of the abnormal nozzle and the binary data are also corrected so as to form a compensation dot, which has a color different from a color used by the abnormal nozzle, in the vicinity of a dot forming position by the abnormal nozzle.

Publication number: 20070247539Abstract: A multi-stage lens driving device comprises a lens holder, a lens mounted on the lens holder, a carriage carrying the lens holder in a movable manner, at least one magnet coupled to the lens holder, at least one coil disposed on the carriage and corresponding to the magnet, and at least one yoke disposed at a predefined position of the carriage. Through the magnetic field produced by the magnet and the current action in the coil, the force generated thereof can push the lens holder to move toward a desired position, thereby achieving the effect of focusing or zooming. In addition, through the attraction between the yoke and the magnet on the lens holder, the lens holder may be secured to the predefined position. That is, the lens is firmly secured even when the coil current is shut off, thereby achieving the goal of saving power consumption.Type: ApplicationFiled: January 16, 2007Publication date: October 25, 2007Inventors: Wen Ho, Chi Chang, Heng Yu
