[0048] figure 2 The structure of the moving picture encoding device of the first embodiment of the present invention is generally described. Except that the refresh map creation unit 800 is replaced by the qualitative refresh map creation unit 100, and the self-image display unit 101 is additionally provided, the moving picture coding apparatus is basically similar in structure to the corresponding part in FIG. 1 . exist figure 2 In , the same parts as those in Fig. 1 are designated with the same reference symbols. In order to simplify the description, in the following discussion, the operations of the same parts will be omitted.

[0049] Self-image display unit 101 includes a display device, for example, LCD (Liquid Crystal Display), for displaying image data supplied from moving image input unit 1 . The self-image display unit 101 is configured to display a mark on the display screen so as to limit the area where an object can be displayed, so that by referring to the mar...

Abstract

A moving image coding apparatus has a blocking unit for dividing an image applied in units of frames into a plurality of blocks, a mode selection unit for selectively performing intra-frame coding for performing coding within the same frame, and inter-frame prediction coding for performing coding between frames, for each of the plurality of blocks, a self-image display unit for displaying the image, and a qualitative refresh map creation unit for creating a refresh map which sets a shorter refresh period for a block corresponding to a predetermined area on a display screen of the display means than the rest of the plurality of blocks. The mode selection unit performs the intra-frame coding at the refresh period set in the refresh map.

Description

technical field [0001] The present invention relates to a moving picture encoding device and method, which are applied to moving pictures in video telephony, video conferencing and the like. Background technique [0002] Video telephony is limited by the transmission of low bit rates and error environments where data transfers are highly sensitive to errors. Therefore, in order to improve image quality, video telephony commonly used moving image coding includes proper selection of frame-intra-coding and inter-frame predictive coding, in which frame-intra coding utilizes the correlation of adjacent pixel levels in the image for coding, and frame- Inter-predictive coding utilizes the pixel correlation of the just past frame and the current frame for coding, so that the appropriate coding is applied to each region. [0003] Intra-frame coding is characterized by high error immunity, but generates a large number of codes in it. On the other hand, inter-frame predictive coding ...
