At present, the video acquisition and compression system which is based on PC achieve the purpose of video capture through a dedicated video capture card by using PC's powerful data processing capabilities and its marvelous interface. Although the PC-based system is currently widely used and with a strong processing power, it can't meet the requirements in many occasions because its great power consumption, high cost and the need for personal maintenance and management is incompatible with present developing trend as instrument miniaturization, low power consumption and portability. Based on the combination of the development and practical application of video image technology and the requirement of the system and the specific comparison of the advantages and disadvantages of various schemes, this paper proposes a design scheme of embedded video acquisition system based on ARM.
