Title Research on Video Image Capture Technology
Abstract
With the development of the Times, image acquisition system has a wide range of application in many fields. The traditional image acquisition systems tend to have the shortcomings of large volume, high power consumption and complex structure， while compared with traditional image acquisition systems, embedded systems have the advantages of small size, low cost, high reliability, good flexibility etc. In recent years，embedded systems get more attention and research.
This paper studies the acquisition and display of video images. In familiar of image decoding chip TVP5150, ARM9 chip S3C2440, Linux system platform development and Video format BT.656, video image acquisition circuit is designed based on the application of TVP5150 and S3C2440.Flow chart of the driver of the video conversion module has been given. The configuration of TVP5150 register, camera interface signal and the DMA data transmission of the set and working process are carried on the thorough analysis in this paper.
