Patent number: 7492960Abstract: A method of coding a moving picture is provided that reduces blocking artifacts. The method can include defining a plurality of defining pixels S0, S1, and S2, which are centered around a block boundary. If a default mode is selected then frequency information of the surroundings of the block boundary is obtained. A magnitude of a discontinuous component in a frequency domain belonging to the block boundary is adjusted based on a magnitude of a corresponding discontinuous component selected from a pixel contained entirely within a block adjacent the block boundary. The frequency domain adjustment is then applied to a spatial domain. Or, a DC offset mode can be selected to reduce blocking artifacts in smooth regions where there is little motion.Type: GrantFiled: April 18, 2008Date of Patent: February 17, 2009Assignee: LG Electronics Inc.Inventors: Hyun Mun Kim, Jong Beom Ra, Sung Deuk Kim, Young Su Lee

Publication number: 20080273070Abstract: A bubble removing apparatus for removing air bubbles in ink to be supplied to a printer head of an inkjet printer and a method of removing the air bubbles are provided to provide a smooth flow of ink to the inkjet printer head. When an air bubble removing operation is performed, ink in an ink tank is moved towards the printer head through a filter unit by operating the pump in a forward direction, and the ink that has moved towards the printer head is returned to the ink tank through the filter unit by operating the pump in a reverse direction. Air bubbles trapped in the filter unit are moved to the ink tank due to the operation of the pump in the reverse direction and are removed in the ink tank by the gravitational force, and thereby a smooth flowing ink supply can be provided to the printer head.Type: ApplicationFiled: October 2, 2007Publication date: November 6, 2008Applicant: Samsung Electronics Co., Ltd.Inventors: Il-ju MUN, Young-su Lee

Patent number: 7438398Abstract: An ink cartridge and an inkjet printer using the same. The ink cartridge includes a cartridge case having an ink storing space, negative pressure forming foam inserted into the cartridge case, and a filter pipe installed on a bottom surface of the cartridge case, wherein the bottom surface of the cartridge case is formed to be entirely in contact with a bottom surface of the foam. Thus, a dead space around the filter pipe is minimized or eliminated, therefore solving a problem where the ink would otherwise remain to a certain extent in the dead space. In addition, the air existing in the dead space together with the ink does not affect the ink ejection performance of a head due to expansion and shrinkage of the air to stably maintain the ink ejection performance.Type: GrantFiled: December 27, 2004Date of Patent: October 21, 2008Assignee: Samsung Electronics Co., Ltd.Inventor: Young-Su Lee

Publication number: 20080225524Abstract: Disclosed is an intense pulse light device, in which plural divided light filters coated with individually different materials are rotatably and uniformly aligned around a reflection mirror in order to selectively filter lights according to wavelengths thereof, so that it is not necessary to exchange a handle body or filters, thereby improving convenience of use for the IPL device, and in which the loose contact of power lines and signal lines, leakage of cooling water, and penetration of impurities can be prevented, thereby improving reliability of IPL device. A semicircular reflection mirror aligned around a flash lamp installed in a body and a light filter section is aligned around the reflection mirror while forming a predetermined space therebetween. The light filter section is uniformly divided into two or four light filters so as to increase selectivity for the light radiated from flash lamp.Type: ApplicationFiled: April 2, 2004Publication date: September 18, 2008Inventor: Young-Su Lee
