Color-converting an outline or other portion, with or without spreading of the portion
 This invention provides an image processing apparatus provided with an outline extracting section for extracting an outline of an input image and a color converting section for converting the color of the outline extracted into a predetermined color. This apparatus is therefore capable of extracting the outline of an input image, applying color conversion to the outline extracted, and emphasizing a pattern such as a character, a graphic pattern or the like. The apparatus is further provided with a converting-color designating section for designating a converting color to be applied to the outline, a color detecting section for detecting a portion having a predetermined color in the input image, and a region designating section for designating a predetermined region in the input image. Accordingly, the outline alone can be independently processed so that an outlined character, a shaded character or the like can be formed.
