CCD Image Capture & Processing

Image is a main medium that people transmit information. According to statistics, 60 percent of the knowledge that people get from outside is given by all kinds of picture. So as the important medium and means of transmitting information, image information is very important. Image processing is momentous significance to people. Image is a main source of getting information. The technology of image processing is important to the national economy and the people's livelihood. CCD image is digital image. With the development of science and technology, CCD image is applied more widely and it has been applied in communication, industry, military and so on. It is more and more useful in the national economy and the people's livelihood.In the course of CCD image processing, the conventional way of getting image is controling the image capture card to freeze,save and read the image. Because the amount of the image data is large, the time used in freezing, saving and reading is so long that it extends the time of processing image. So it is difficult to realize real time processing. In order to meet the real time processing, this paper studied a new means of getting image - capturing in the screen. Firstly, it introduced the conventional way of getting image, CCD sensor and basic CCD image processing system. Secondly, it introduced the fundamentals and the program of realizing the capture. It mainly analysed the error between the capture image and origin image. And it accounted the time of getting image by conventional way and by capture. According the research, the way of capture image is successful and it has many advantages. In the end, after introduced much means of processing image, image capture is applied in static image processing and dynamic image processing. And it dose much work on the error analysis.This paper belongs to application research. The new method of getting image and the program are successful and they are worthy.
