提供了一種低成本的數(shù)字圖像處理解決方案。研究了以DSP為核心的高性能壓縮和處理系統(tǒng)。系統(tǒng)使用CCD獲取原始數(shù)字圖像數(shù)據(jù)，采用快速算法實現(xiàn)了核心的二維DCT變換，經(jīng)過編碼后，在一個16位定點DSP上實現(xiàn)了快速圖像壓縮。實驗證明，該系統(tǒng)性能良好。

With the development of Internet and consumer electronics, multimedia technology, including audio, video, static image and etc, has been widely used in various kinds of applications. Digital images, which were once a dream for most people, become a degage and simple procedure ascribing to the appearance of digital camera. For the reason that Digital Signal Processor (DSP) is the core of digital camera in general, the research of implementation of real time image procession on DSP is important. The goal of this thesis is to establish a high performance image processing encoding system on DSP.
