Research On Application Of Dynamic Video Image Capture

Image information are mainly medium that people transfer information, according to statistics, about 70% percent of the knowledge that people get from outside is given by all kinds of image. So as the important medium of transfer information, image information is very important. Image process is momentous significance to people. With the rapid development of science and technology, the technology of image process is important to the national economy and the people's livelihood. Image process 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. But with an eye to domestic circumstance, the technology application is not just very widespread. Though the image compress technology have get the important meaning in the aspects of image transfer, but the very high quality real-time image is demand in some situations, the lose detail in image was usually exactly our concerns of by compression. Aim at these blemishes, study with develop to have the real-time image system is an importance development direction that current image process field.In the course of image capture technology, the conventional way of get image is control the image capture card. Because the amount of the image data is large, save and read is so long that it extends the time of process image. So it is difficult to realize real-time detect and process. In order to achieve real-time process, this paper studied a new means of capture image, designed and complied the modularization real-time system, discuss the new real-time processing way used to been image. The system can capture dynamic real-time image without a PC, according the research, the way of capture image is successful. The system based on microprocessor and CPLD, at the time implement the dynamic image capture system, the system designed and debugged experience is summarized and analyzed in detail also.The chapter two introduce the system summarization and introduce image capture technology, familiar image formats, and introduce the way how to realize the system in the end. The chapter three introduces the real-time image display system, and detail introduce the chips' function, configuration and working theory , designed the circuit and tell us how to initialize to the system in the end. The chapter four analyzed the image format and capture way, introduces the programmable controller, detail introduces MaxplusII development environment, design the system circuit and edit the key code. The chapter five introduces the Printed Circuit Board design in the image capture system. Analyze the questions will be discover during the image capture design and put forward solve methods. The chapter six summarized the system debug. In last chapter, we analyze the advantage of the solution, and show a perspective eye of the development of image real-time process.This paper belongs to application research. It has some practical value to the research of new image' s capture and also the system we developed.
