ABSTRACT
Image compression is a process that using the least amount of data to indicate as many as possible of the original image information. For images, if want to quick or real-time transmission and a large amount of storage,the needs is image data compression. Image compression once belonged to personal computer (PC) areas, are now widely used in embedded environment. The results of this trend is largely due to the new handling capacity of the MCU and multimedia enhancements improved.
UC/OS is a common using operating system in embedded development work. This paper make use of UC/OS real-time operating platform to call the conversion process. First, this paper introduced the image compression of the need and feasibility of the situation. Second,this paper introduce the basis of the theory of image compression, international standards, all kinds of compression and encoding method steps of a variety of compression algorithms, and show one of the compression method used examples to elaborate. Third ,this paper analysis the design work of my graduation with the theoretical in the last part. Graduated from my design work , it bring up more better amendments.The focus is that list out my own program and let more people understand the secret of compression.
