The Research And Realization Of Image Collecting In Embed System

With the rapid progress of multimedia technology and computer networks, the research and realization of gathering images have been highlighted in embedded systems. Currently, Using its powerful processing capability and overall interface to design the image collection card, the equipments of images collecting system are mostly based on personal computer, and the application is very extensive.However, because of his huge size, high costs, inconvenience.In many outdoor occasions, Personal computers are not suitable for the images collection, in such environment, the dedication to design of a portable image collection system became necessary for the market.In this thesis,The feasibility of realizing an embedded image collection system is investigated, A scheme of image collection based on S3C44B0X is designed. The corresponding hardware, circuit elements chart and the substrate software module are proposed, Aiming at the digitalization of video image, the liquid crystal display (LCD) and storage of image, as well as the transferring of collected images by computer, with the chip S3C44B0X as the chief processing chip, the system mainly includes A/D convert circuit, LCD and touch screen circuit, and The embedded networks transmission .at the same time, The uC/OS operation system with S3C44B0X chip is designed so that a thin body web server is formed. In the whole design the flexility of image collection is considered sufficiently, so the whole system can be used as a general image collection flatform. This flatform can be used to realize any compressing algorithms or protocols. This system has an excellent expansibility and is easy to be developed secondly.The techniques of embedded system became the most popular technique in electronic realm currently, which have already broadly been applied in the military national defense, consume electronics, network correspondence, industry control etc. each realm. From my thesis, This set of hardware system can be applied in LCD manifestation, the desktop video pattern, multimedia teaching, digital television, picture handle, screen phone and collecting videoand frequency signal, and the outdoor image collection etc.At the end of this thesis, the debugging and testing of the entire embedded image collection based web server is demonstrated. The experiments show that this compression system can reach those targets required initially. And the results prove that the design is correct.
