动画再生方法及动画再生系统;MOVING IMAGE REPRODUCTION METHOD AND MOVING IMAGE REPRODUCTION SYSTEM

摘要

本发明提供动画再生方法和动画再生系统。在动画播放中，藉由仅使用浏览器的标准解码功能，提供终端依存性小的制作环境，并提高压缩率，实现流畅的动画播放。;在制作应在客户终端2播放之动画的压缩资料继而储存在网路伺服器1之时，对于构成动画的各画面，依次以JPEG区块单位实施JPEG压缩，并排列至JPEG压缩静止图像资料12。但是，对于在画面间采用动作补偿且能够从前画面而加以利用的资料，不排列至JPEG压缩静止图像资料12，而在图像复原用压缩资讯13中将该要点加以记述。利用浏览器21而被加以解读的显示程式11系记述有如下内容：从已制作之JPEG压缩静止图像资料12而针对原来的动画进行再构成。显示程式11系被下载至客户终端2且被加以执行，藉此动画被显示在显示画面22。; judging whether each of the blocks has same information in the preceding frame ; obtaining compressed data by encoding each block for which the preceding frame does not have the same information by a method compatible with a still image decoder ; preparing compressed still image data in which the compressed data are arranged in succession ; describing, for each block, information indicating presence/absence of the same information into image restoration information ; preparing image restoration compressed information by encoding the image restoration information ; and preparing a display program which is written in a description language that can be interpreted by the browser for reconstructing the data of moving image.
