    摘要: An image processing apparatus for converting color images into monochromatic pattern images. The image processing apparatus includes: means for detecting the area of a color image (508); means for converting a color image into a monochromatic pattern image (507); and control means (523) for varying such image processing in accordance with the result of detection made by the means for detecting the area. When a thin line is detected (521) in a color area, the method of processing is determined based on the width of the detected thin line. For example, when the width of the thin line is smaller than a predetermined value, the area of such thin line may be outputted as a plain image instead of a pattern image so that it may easily be seen or recognized. The contour of a color area may be made conspicuous by combining a plain image and a pattern image.
