摘要： According to an image processing method and apparatus of the present invention, an outline portion is extracted from input image data, and a pixel whose dot size is to be changed is extracted. The input image data is printed without any change, and the pixel whose dot size is to be changed is overlap-printed while the dot size is increased. Therefore, smoothing can be sufficiently performed in both the main scanning direction and the sub-scanning direction without increasing the dot density and decreasing the recording speed.

摘要： Whether or not a color image is present adjacent to a black image is discriminated. Whether the black image is formed using a black ink or a plurality of color inks C, M, and Y is determined in accordance with the discrimination result. When the black image is formed using the plurality of color inks, it is recorded using a repetitive pattern of two of C, M, and Y so as to prevent blurring with the color image, and to improve fixing characteristics by decreasing the total ejection amount.

摘要： A recording head having an ejection portion group (10d) for ejecting a black ink, and ejection portion groups (10a,b,c) for ejecting color inks is used. When a black image to be printed by the black ink is present adjacent to a color image to be printed by the color ink, a black image portion adjacent to the color image and a black image portion which is not adjacent to the color image are formed in different scans, thereby obtaining a high-quality image from which ink blurring at a boundary portion between the black and color images is eliminated.
