发明名称 IMAGE PROCESSING APPARATUS AND METHOD FOR CONTROLLING THE SAME
摘要 PROBLEM TO BE SOLVED: To keep the image quality regardless of fluctuation of physical registration generated between a recording apparatus and a recording medium, to suppress granular deterioration depending on the low frequency component of an image, and to make it possible to form the image with the high image quality. SOLUTION: An image forming apparatus calculates respective recording amounts of a plurality of recording elements on every recording scanning of a recording head in accordance with image data, and restricting information indicating ease to select as a dot forming position on the positions of respective recording elements is acted on the calculated recording amounts to apply an N-nary processing (N is an integer of 2 or larger), to prepare a dot pattern in the recording scanning. In addition, the image forming apparatus detects physical amounts of variation on at least either a recording head and a recording medium during performing a plurality of numbers of recording scanning. Then, based on the calculated recording amount, the prepared dot pattern, and the detected amount of variation, the restricting information is renewed. On the next recording scanning, the renewed restricting information is referred for forming the dot pattern. COPYRIGHT: (C)2010,JPO&INPIT
