<P>PROBLEM TO BE SOLVED: To provide a print system capable of improving the picture quality of a part of low picture quality due to JPEG compression by deleting noise of a part where no drawing data are originally present, and of transmitting a small amount of print data, in a print system which performs print processing on the basis of image data including gradation information. <P>SOLUTION: Print data generated according to an application is subjected to raster processing and further raster data are highly compressed through, for example, JPEG compression and also converted into, for example, black-and-white binary image data, which are added to the highly compressed data to transmit the compressed data to a printer device. On the printer device side, both the data are put together through OR operation to remove noise nearby, for example, a white part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
