1. TECHNICAL FIELD OF THE INVENTIONn n n The present invention relates to a ripple scan device and a method thereof, and an image coding / decoding device using the same.n n n 2. The technical problem to be solved by the inventionn n n The present invention provides a method and method for realizing a ripple scanning apparatus for repeating a process of coding image information located at a neighboring outer side immediately after first coding image information at an arbitrary position. A computer-readable recording medium that records the program, and a water ring scan order, deliver visual information that is suitable for the human visual system (HVS) to achieve visually superior image quality. An object of the present invention is to provide an image coding / decoding apparatus and a method thereof, and a computer-readable recording medium having recorded thereon a program for realizing the method.n n n 3. Summary of Solution to Inventionn n n The present invention relates to a method comprising: a ripple scan start means for starting a ripple scan from a ripple occurrence position (ripple (0)), which is a visually important specific image portion to be subjected to ripple scan first; After determining the next ripple scanning position (ripple 1) in the form of enclosing the square ring at the ripple occurrence position, the next ripple scanning position in the form of enclosing the rectangular ring in the previously processed square ring Ripple scan positioning means for determining ripple (i); And ripple scanning means for performing a ripple scan in accordance with the ripple scan position determined by the ripple scan position determining means.n n n 4. Important uses of the inventionn n n The present invention is used in the field of image processing. |
