Intelligent Water ring scan apparatus and method using Quality Factor, video coding/decoding apparatus and method using that

摘要

1. the art that the invention set forth in the claims ; Stir intelligent scanning apparatus and method and video encoding / decoding apparatus using the same, and will on a computer-readable recording medium recording a program for realizing that method, and the above methods. ; 2. The invention is a technical problem to be solved ; The picture quality of a specific portion position the human visual system (HVS: Human Visual System) suitably imaging method for delivering visually preferentially selectively enhance the image quality of the portion to be performed on a coding so as to obtain an excellent picture quality by the information in the and devices, providing a computer-readable recording medium recording a program for realizing the method. ; 3. The gist of the solution of the invention, ; A video encoding device, referred to in parts for the image to be encoded to be handled in a variety of image quality for the human visual system characterized by varying the amount of information processed based on the importance of the position of the specific portion of the image. ; 4. important use of the invention ; Video encoding / decoding used to fight. ; Stir scanning, encoding, decoding, Quality Factor
