The design of image monitoring system for the electric scene
Abstract: With the fast development of video and monitoring technology, the range of its application is expanded. The electric scene monitoring is one of the examples. It is significant to safety of production and improve efficiency. The monitoring system is profit for manage and automation of production. 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, the I2C bus which is used to initialize and the necessary video memory (FIFO) has been also described in the system.
Key words: monitoring system image capture SAA7111A I2C-bus video memory (AL422B )
