[Abstract]:In recent years, with the development of image sensor technology and the progress of digital image processing technology, the application of digital high-definition camera is becoming more and more urgent. Image processing plays an important role in image quality of digital HD camera. Under this background, it is of great significance to study the processing algorithm of high definition camera based on DSP. This paper mainly studies the camera processing algorithm and gives the implementation based on DSP. The camera image acquisition system chooses the FPGA DSP structure, which can make full use of the characteristics of the two processors. Firstly, the automatic exposure algorithm in camera is studied in this paper. Secondly, based on the study of a large number of automatic white balance algorithms, an improved automatic white balance algorithm is proposed, which combines the advantages of several typical white balance algorithms. Finally, the realization of automatic exposure algorithm and automatic white balance algorithm on TMS320DM6467 platform is given. The application in the real camera shows that the algorithm can be realized and can achieve the ideal effect.
