<p><P>PROBLEM TO BE SOLVED: To transfer data from an image processing unit to an encoding unit without using an external memory and to perform high-speed processing by internal transmission having a wider band than the external memory. <P>SOLUTION: An entire image 41 of an original image is divided into six (64×4)-pixel blocks. Enlargement processing is performed for each of the blocks. Data are read from each of the blocks in the order of the number assigned such as 1, 2, 3, .... The first block is processed by a size modification unit to generate image data on a (128×8)-pixel block 42. A unit of (16×8)-pixel macro block 43 is read out from the image data 42 and encoded to obtain JPEG data 44. A code rearrangement unit rearranges the order of JPEG data 46 in the block unit, thereby generating JPEG data 8. When the JPEG data 48 in this order are decoded, it is possible to obtain a decoded image 49 whose block order coincides with the area 41 of the original image. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
