<P>PROBLEM TO BE SOLVED: To provide an image processor, its control method and its program for achieving efficient rendering processing with a saved memory by determining the division size of a tile vector based on rendering processing capability and band memory width. <P>SOLUTION: Raster image data are divided into blocks of set first block size, and vectorization processing is executed to each block so that the raster image data can be converted into block vector image data. The block vector image data are converted into the raster image data. A prediction time required for the block vector image data to be processed is predicted. The block vector image data to be processed are re-converted into the block vector image data of a second block size smaller than the first block size based on the predicted prediction time. The raster image data acquired by developing the acquired block vector image data are output to an image output part. <P>COPYRIGHT: (C)2008,JPO&INPIT |
