摘要

八十年代中期，随着硬件设备的发展，使得图像技术和多媒体技术得到了长足的发展，计算机处理的内容由当初的单一文字扩大到了动画、文字、声音、视频、图像等多种媒体形式。目前，伴随着网络技术和Internet的发展，图像技术的功能得到了更好的发挥。本文详细描述了图像和图形技术的产生，发展以及在现实生活中的实际应用；分析了表示媒体、显示媒体、存储媒体和传输媒体间互相如何协同工作的运做过程；阐述了有关图像技术的关键点，开发技术和应用前景。本文以自主开发的图像系统为基点，论述了软件开发的过程，模式和技术点。对于图像技术的编码格式，格式转换，数据压缩和流媒体技术结合等应用进行的详细论述。软件系统采用了大量的设计模式和软件工程方法，解决了内聚与耦合的问题，实现了软件的易扩展与易维护，文中也对设计模式做了详细的叙述，并且对现今流行的图片格式和这些格式的开发进行了介绍。同时，本文围绕着图像浏览系统的剖析进行展开，列出了一些如BMP转AVI等关键技术的代码，以及一些框架的设计,以十六个本系统主要功能为框架，对每个功能以及相关技术的历史，发展和开发做了论述。对一些相关的技术和技术点也做了解释和说明。解决的图像浏览技术方面一些问题。

Abstract

In the middle of the 1980’s, with the development of the hardware and computer device, graphic technology and multimedia technology are developing more and more quickly. The contents which computers are able to process extend from the single style of characters to the motivation, sound, video and graphics. Nowadays, with the aid of the Internet, graphic technology and image manipulation are easily bringing into play in our daily life. This paper detailedly describes the generation and the development of the image technology and graphics technology; analyses the relations of the perception medium, representation medium, presentation medium, storage medium and the transmission medium; discourses upon the key point, developing technology and the application prospect. This paper is based on the graphic system, which is developed by the author. It not only dissertates the common procedure, patterns and technical points in developing of the software. But also it discussed the coding, format exchange and data compressing in the graphics. This graphic system exercises lots of design patterns and software engineering methods and solves the problems of cohesion and coupling. It achieves the extendibility and usability of software. All above especially the design pattern are depicted in the paper. Meanwhile the paper introduces the popular formats of pictures and with the analysis of this graphic browsing system; we discuss the framework of this system and some key codes such as BMP converting to AVI. There are 16 main parts in the paper. In each part, we discourse and explain on the history, development and exploitation of the related technology.

Key words：image coding image browsing image compressing design pattern
