Digital Camera Image Processing Algorithm Research And Applications

In recent years, digital cameras for still images and movies which developing rapidly are a new product involving many technical fields, such as optics, electronics and computer, and now are used in every walk of life. Digitize and image processing are key technology of digital camera. So research and development of digital camera is very significant work. This paper does certain researches on image processing of digital camera. Based on these algorithms several application soft was designed. The main contents are summarized as follows:1 .It studies the structure of imaging and digital camera. In this paper ,it gives the mechanism of charge-coupled devices and its plane borehole pattern, and show how the digital camera work.2.It studies the reconstruction algorithm for digital camera. The theory of color is firstly introduced, then algorithm are studied in this paper, these algorithm are subtracting of fix-pattern noise, color reconstruction auto gain control algorithm and auto white balance algorithm, then designed a download soft for digital camera.3.It studies the algorithm for image enhancing and compressing. In image enhancing aspect, it studies medium filtering algorithm~ vector filter and image sharpen algorithm. According to the characteristic of digital sampling,a new image sharpen algorithm is given, and it is more effective. In image compressing aspect, it mainly studies the JPEG algorithm. All of these algorithms are used in soft designing.4.It describes the standard and video for windows kits, and introduces mechanism for digital video of digital camera before an application soft was designed.
