<P>PROBLEM TO BE SOLVED: To provide an image processing apparatus for reducing access amounts to a memory. <P>SOLUTION: A shared memory 18 is accessed from a CPU or an image processing part 16 through a shared bus 12. The shared memory 18 stores image data 50 in which pixel data rows generated by scanning and stretching in a main scanning direction lie in a sub scanning direction. When the image processing part 16 performs reducing processing of the image data 50, a sub scanning line extraction part 20 reads the pixel data rows by thinning out in the sub scanning direction. Then, a sub scanning interpolation part 28 interpolates in the sub scanning direction, and a main scanning interpolation part 36 interpolates in the main scanning direction to generate the reduced output image data 39. <P>COPYRIGHT: (C)2008,JPO&INPIT |
