摘要： An ink-jet image forming apparatus. The ink-jet image forming apparatus includes a print head having a plurality of nozzles to eject ink, an ink tank to store the ink, an ink supply passage to supply the ink in the ink tank to the print head, an ink return passage to return the ink in the print head to the ink tank, a regulator mounted in the ink supply passage to regulate ink flow supplied to the print head, a shut-off valve mounted in the ink supply passage, between the ink tank and the regulator, to intercept ink flow supplied to the regulator, and an ink pump mounted in the ink return passage to forcedly flow the ink in the ink return passage. The ink pump is configured to be driven in forward and reverse directions so as to change an ink flow direction. Since the shut-off valve intercepts forcedly the ink flow in the ink supply passage, the ink in the ink tank is prevented from flowing abnormally to the print head and leaking from the print head.

摘要： 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.
