Based On The The Icx227ak Color Night Vision Ccd Camera Design And Realization

In the field of monitor and control, going with the development of the science and technology,people desire the higher quality of image.As a type of image sensor with the high performance,the CCD became the main image acquirement device using at the advanced equipment for the monitor and control naturally because its high resolution,high sensitiveness and high dynamic range and so on meet the market;at the same time, wireless video and audio transmission system has been used more and more because of its convenience and nimbleness.The aim of this paper is researching a type of high performance CCD camera with the ability of wireless video and audio transmission for the field of monitor and control,to occupy the market.So,In this paper,aimed at the necessity of practice and basing on the theory of the CCD image sensor,I studied on how to improve the quality of the image and how to get the effective image at night,and designed a type of CCD camera with the ability of wireless video and audio transmission .The main work in this paper as follows:1. Accomplishing a new design about CCD camera and produce the hardware.2. Design and produce the other corresponding circuits in this system.3. Researching the infrared CCD and applicating it in the system for night.4. Analyse the reason of producing noise in the CCD image sensor and study on the method for reducing the noise.5. Presenting the idea that using wiener filter technology for reducing the noise of the camera in the monitor system.6. Accomplishing the code of wiener filter and apply it to the system.7. Succeeded in applying this project on the A&V wireless transfer and settle the problem of the EMI.After analyzing and researching of these points,the paper finished the full design of this system and discussing the justification and the feasibility.When achieved the main function,this paper carry through a careful and strict test to th e full system.The practical results shows that the CCD camera with the ability of wireless video and audio transmission can get fine image no matter day or night and has achieved the intending purpose.The...
