  •   本論文主要是利用高效能的訊號處理晶片來達到快速的JPEG壓縮和解壓縮,和驅動DSC 25 所提供影像週邊裝置:如CCD Control,預覽引擎等,如果我們能提供多方向適當的監控,相對的效率也較高.因此設計一塊四個通道channel)合成一channel 的電路板來做影像輸入。加上在影像處理方面,我們採用DSC 25 影像的處理加速器,並做初步判斷偵測畫面是否有物體在變動並加以儲存,如果把此功能運用在自動提款機上,則可以達到高效率多通道錄影器系統。

      The main research of the thesis utilizes DSP with high capacity and efficiency to achieve fast JPEG encoder and decoder, and drive the peripheral image device of DSC25, such as CCD Control , Preview Engine . If we can offer multi-direction and proper control, efficiency is also relatively high .Such that a circuit board with four channels composing a channel is designed as a image input . In addition, we adopt the image accelerator of DSC 25 to deal with the image processing . Furthermore the system can judge and detect the change objects in the picture and store data . If we use this function on the Automatic Teller Machine(ATM), we can the achieve high-efficiency Multi-Channel video recording systems .
