  • Patent number: 7193750
    Abstract: Disclosed is an image processing method. According to the present invention, the image processing method, whereby a multi-value bit map development area, in which is stored a multi-value bit map that represents an output image, and a plurality of pattern planes, each of which corresponds to an attribute of an object, are employed to develop a drawing command and to perform a color process, comprises the steps of developing a multi-bit map in the multi-value bit map development area in accordance with a drawing command, determining an attribute for an object by using the drawing command, developing the bit map, which is consonant with the drawing command, in one of the pattern planes that corresponds to the attribute of the object, and controlling a color process for the multi-value bit map in accordance with the bit maps developed in the pattern planes.

  • Patent number: 7127113
    Abstract: The present invention aims to enable image attribute discrimination of an image indicative of compressed data, and hence correction processing on the image indicative of the compressed data. In attaining this aim, the compressed data are developed into a bit map by a method corresponding to the analysis results so that the correction processing will be performed on the bit map according to the identified attribute.

  • Patent number: 6456404
    Abstract: Image information which represents an object image and includes a logical operation table is input to a color convertor which converts the input image information into color image data including a black density component and a plurality of color density components. A data convertor converts the color image data into a linearly independent color image data by converting the blank density component into a plurality of color density components. A logical operator performs a logical operation on a plurality of color component data forming the linearly independent color image data on the basis of the logical operation table.
