Embodiment Construction
[0104] Next, an embodiment of the present invention will be described with reference to FIG. 1 to FIG. 21 .
[0105] FIG. 1 is an explanatory diagram of a window. The window 21 of the face is distinguished from the background image 22, and the weighted average of information is carried out at the same time; the window 21 of the face is taken as the key point, and on the contrary, the image quality of the background image 22 is deliberately reduced to reduce the amount of information. And, by using the window 21 of the face to follow the movement of the shaking face, it is continuously updated to the latest position.
[0106] The specific area that moves arbitrarily in the picture of the dynamic image in the recognition process, that is, the window (21) of the face that is prioritized for information processing, and all the pixels that make it are sequentially divided into small rectangular blocks. , and use the motion vector accompanying the dynamic image motion of the small ...

The present invention provided a high-performance code compression system, in which image information on a dynamic image is compressed and reduced in an image transmission line with a limited information transmission amount, which shortens the transmission delay time and which reduces hardware constituting the system. A section whose importance is high in an image, e.g. a face which contains the movement of lips accompanying talking, is discriminated from a part whose importance is low, e.g. a background other than the face of a human. This information processing operation is weighted, so as to enhance its information transmission efficiency. When difference information on a frame B is forcibly changed into an image having zero value, an image in a transmission source can be restored in a transmission destination, on the basis of least information. A discrete cosine conversion part and a quantization part can be omitted from an encoder, and the compatibility of the high-performance code compression system with the conventional systems is guaranteed.
Description
[0001] This application is a divisional application with the application number 01140078.1, the application date is November 26, 2001, and the invention name is "High-performance encoding and compression system for dynamic image information". 【Technical field】 [0002] The present invention relates to a coding and compression system for moving image information with a lower bit rate required for videophones and the like. In other words, in the image information, there are more important parts, such as the facial image of the lip movement when a person speaks in a videophone; there are also less important parts, such as the background other than the person's facial image; distinguish them , focusing on the important part of information processing, in order to improve the efficiency of information transmission. At the same time, the original telephone line restricts the growing transmission capacity. Only by compressing the amount of image information transmission to the minimum,...
