<p><P>PROBLEM TO BE SOLVED: To provide an image coding apparatus for preventing an increase in data transfer quantity to a memory so as to reduce the circuit scale and the processing time in the case of outputting a plurality of coded data with respect to one image input. <P>SOLUTION: The image coding apparatus includes: a coding unit 100 for generating a code A; a coding unit 110 for generating a code B; an image reproduction unit 200; an image reproduction memory 204; and a motion vector detection unit 300. The coding unit 100 generates the code A, the image reproduction unit 200 rebuilds up an image by using an output from the coding unit 100 and stores the image to the image reproduction memory 204. In the operation for generating the code B, the coding unit 110 is employed as a coding unit for generating the code B, while commonly employing the image reproduction memory 204, the motion vector detection unit 300, and the image reproduction unit 200 as employed in the operation of the generating the code A. <P>COPYRIGHT: (C)2004,JPO</p> |
