Abstract: All threshold data applied to processing is read into a register so that threshold data read from threshold matrix memory can be recycled until the end of a scanning line for processing, and is selectively output to a plurality of comparison means for executing parallel comparison processing. The threshold data set in the register is shifted in order for repetitive use. The threshold data of the next scanning line is read into the register during the comparison processing, and upon completion of processing of one scanning line, comparison processing on the next scanning line is executed as pipeline processing. Threshold data read from the memory needs to be executed only once for each scanning line for processing, and threshold data can also be read during halftone data generation of the preceding line.

Abstract: Moving images, of the same content, having different resolutions are divided into a plurality of tiles and encoded tile by tile to generate bit streams. When decoding, the minimum number of tiles necessary to display are acquired and decoded. Further, moving images having a high resolution and those having a low resolution are decoded in parallel. The moving images having a low resolution are enlarged and used for substitution until the decoding of the moving images having a necessary resolution is completed.

Abstract: A print processor is disclosed which comprises: an input unit for inputting print data including at least either texts or graphics and described in predetermined drawing instructions; an image output unit for outputting images based on data having a predetermined data structure; an intermediate data generating unit for generating intermediate data from the print data, the intermediate data being expressed in a format which is higher in abstract terms than the data structure and which includes at least one basic graphic; an rasterizing process unit for rasterizing the intermediate data into the data structure and for supplying the image output unit with the intermediate data thus rasterized; a determining unit for determining a number and a size of the basic graphics constituting the intermediate data generated by the intermediate data generating unit; an rasterizing time predicting unit for predicting the time it takes the rasterizing process unit to rasterize the intermediate data on the basis of the number
