摘要： Image data is divided into blocks each of a 2×2 pixel size, and color-reduction processing is performed for the target block based on color data and attribute data of respective pixels forming the target block. A pattern flag indicating the layout pattern of color data contained in the target block is specified by comparing the color data of the respective pixels in the target block having undergone the color-reduction processing. Color data corresponding to a pixel at a position defined in advance in the block having undergone the color-reduction processing is extracted as color data of the first color. When it is determined that the number of colors in the block is one of two to four, color data of the second to fourth colors are extracted. The pattern flag, the color data of the first color of the block, and those of the second to fourth colors of the block are output.

摘要： Processing is optimized in advance during interpretation of PDL data, so as to accelerating rendering processing during processing associated with image formation. To this end, it is determined whether or not the addition of intermediate data based on PDL data during interpretation to that which is already generated during the processing associated with image formation considerably reduces a speed of the rendering processing.

摘要： A printer interprets the input print data and determines whether or not a rendering command targeted for reusable data included in print data depends on a placement location for placement of the rendering result in a physical coordinate space based on the interpretation result of the PDL data. When the rendering command depends on a placement location for placement of the rendering result in a physical coordinate space, the printer generates cache data without graphic processing for the rendering command targeted for reusable data and stores the generated cache data in a storage unit. When the rendering command does not depend on a placement location for placement of the rendering result in a physical coordinate space, the printer performs graphic processing for the rendering command targeted for the reusable data, generates cache data based on the result of the graphic processing, and stores the generated cache data in a storage unit.

摘要： In forming an image including a spot color, when an image for which a trapping process is performed does not include information of a spot color, the trapping process sometimes functions ineffectively. To solve this problem, image data having information of colors less in number than the colors included in the image is input and two adjacent regions are detected from the input image data. When the color information is color-separated into the colors, it is determined if the two regions share the color, and trapping for an adjacent portion of the two regions is controlled.
