The design of image monitoring system
Abstract: With the fast development of video and monitoring technology, the range of its application is expanded.. The image capturing system is the most important part in this project. What has been gathered by the CCD is the analog signal, it cannot operate by the machine directly .So we selected video decoder SAA7111A of Philips Company as the digitized chip of the signal of the video. The performance and the character of the SAA7111A are mainly described in this paper, and the necessary video memory (FIFO) has been also described in the system.
Key words: monitoring system image capture SAA7111A video memory (AL422B )
