Embodiment Construction

[0055] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] FIG. 1 shows a block diagram of a print controller including an image processing device according to a first embodiment of the present invention in the case of performing overlap determination on the printing equipment side. In FIG. is an image processing device according to an embodiment of the present invention.

[0057] In FIG. 1 , a host computer 1 generates Page Description Language (Page Description Language, hereinafter abbreviated as “PDL”) data and transfers it to a print controller 2 . The print controller 2 is composed of an interpreter 10, a graphics superimposition processing unit 3, a graphics drawing processing unit 12, a CPU 14, an intermediate data storage 20, and a page storage 23. The PDL data input from the host computer 1 is image-processed and expanded on the page. The memory 23 outputs the data in the page memory 23 to the ...

Abstract

An image processing method and image processing method. An overlap judgement processing is conducted only to rectangle drawing of graphics and a drawing command is conducted only to adjacent graphics. PDL data input in a printer controller 2 is input to an interpreter 10. The PDL data is interpreted into intermediate data which is suitable to a drawing processing and then stored in an intermediate data memory 20. The intermediate data is judged whether the data has overlaps with the proximate graphic by a graphic overlap processing part 3 using rectangle data stored in a proximate graphic data memory 21 by a graphic overlap judgement part 11 before drawing on a page memory 23 by a graphic drawing processing part 12. If an overlap exists, coordinate data of the overlapped area of the proximate graphic data is modified. If the intermediate data is not rectangle drawing, data is not modified. The invention is to eliminate an unnecessary image processing time by enabling a judgement of image overlaps using a small processing amount for judgement.

Description

technical field [0001] The present invention relates to an image processing method, an image processing device, an image forming device including the image processing device, a printing device, and a host computer (host PC), especially relates to superimposed graphic (graphic) images and image (image) images for printing, enabling An image processing method for high-speed data processing, an image processing device, an image forming device including the image processing device, a printing device, and a host computer. Background technique [0002] Conventional techniques of image processing for superimposing image data for printing include, for example, techniques described in JP-A-10-233859. In this prior art, image data is used as an object on the print driver side to perform overlapping determination, and the amount of data transfer to the printing device is reduced by removing the overlapping portion, and the processing amount on the printing device side is reduced by con...
