发明名称 Printing Apparatus
摘要 A image process unit includes program memory units that each store a corresponding one of programs for an image processing; a data memory unit that stores therein a set of image data; a program memory bus that interconnects a data analysis unit and the image process unit and carries a printing command; a data memory bus that interconnects the data analysis unit and the image process unit and carries the set of image data; a color conversion process unit that performs color conversion processing on the set of image data on the basis of the printing command and one of the programs; a halftone process unit that performs halftone processing on the set of image data having been subjected to the color conversion processing, on the basis of the printing command and the other one of the programs. The color conversion processing and the halftone processing are performed in parallel.

主权项 1. A printing apparatus comprising: a printing head through which printing onto a printed medium is performed; a data analysis unit that analyzes a print job received from an external apparatus and outputs a printing command and a first set of image data; and an image process unit that performs image processing for converting the first set of image data into a set of printing data on the basis of which the printing onto the printed medium is performed, wherein the image process unit includes a program memory bus that communicably interconnects the data analysis unit and the image process unit and carries the printing command, a data memory bus that communicably interconnects the data analysis unit and the image process unit and carries the first set of image data, a program memory unit that stores therein a program for the image processing, a data memory unit that stores therein the first set of image data input from the data analysis unit, a color conversion process unit that performs color conversion processing on the first set of image data on the basis of the printing command and the program for the image processing, and a halftone process unit that performs halftone processing on a second set of image data resulting from the color conversion processing on the first set of image data, on the basis of the printing command and the program for the image processing, and wherein the image process unit performs the color conversion processing and the halftone processing in parallel.
