Abstract: An image processing apparatus receives color data and includes a masking processing circuit for modifying the colors represented by the color data by processing each of the different color data received. The colors are modified according to other color data associated with each of the colors represented by the color data. The masking processing circuit includes a first memory for storing data representing each color and a second memory for storing data from the data derived after masking processing the data stored in the first memory. The color data and the other color data are used as addresses in the first and second memory. The number of bits of each color data used as an address for each respective color is larger than the number of bits for each of the other color data received at that portion of the memory.

Abstract: 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 and 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.

Abstract: A color image processing system is provided which receives binary image data from an external device, which generates the binary image data, so as to form color images. This system has a first mode in which a receiving side receives the same binary image signal color plane by color plane so that a color process is performed. It also has a second mode in which a printer receives binary image data in a plane sequence, which data indicates color planes corresponding to the types of coloring materials used for a printing operation of the printer, and then, the printer performs binary printing in accordance with the binary image data. An indicating device for indicating the first or second mode selects the first or second mode with respect to the binary image data from the external unit.
