According to the area CCD camera of characteristics, such as high resolution capacity and high frame frequency, this paper puts forward a high speed and parallel image compression system of high integration degree. Firstly, according to the work principle of the area CCD, FPGA is adopted to realize the timing driving and multichannel and parallel analog signal handling to raise the export frame frequency of the area CCD. Secondly, with an image compression scheme based on FPGA embedded processor MicroBlaze and ADV212 compression chip, real time image compression and the high speed area CCD are realized. Finally, by detecting the analog signal of the area CCD output, the real time compression of the big area CCD image is carried out in different compression ratios and the compression performance is analyzed. Experiment result shows that this scheme can realize real time image compression with the biggest data rate of 520Mbps. When compression bit ratio is 0.15, the signal-to-noise ratio of peak value can reach 36 dB. Image collection and image compression are integrated, which reduces the data transmission between them and improves systematic integration degree.

This article in detail on the basis of the algorithm of JPEG2000 standard upon, is put forward based on the FPGA embedded processor MicroBlaze and ADV212 compression chip with the combination of high speed, real time image compression scheme. Experiments show that the scheme can realize the data rate of 520 Mbps largest real-time compression of image data, when the image compression ratio is 53:1, reconstruction image PSNR value can reach 36 dB.
