The paper designs a driving circuit of high sensitive  wide dynamic and high signal-to-noise ratio for binocular CCD imaging system which adopts a Dalsa-made high resolution full-frame 33-mega pixels area CCD FTF5066M. Inner structure and driving timing of the FTF5066M sensor are presented. Field Programmable Gate Array (FPGA) is used as the main device to accomplish the timing design of the circuits and power driver control of the two sensors. By using the Correlated Double Sampling (CDS) technique  the video noise is reduced and the SNR of the system is increased. A 12- bit A/D converter is used to improve the image quality. The output rate of the imaging system designed with integrated chip can reach to 1.3 frames per second through bi-channel. For its good performance  low power consumption and small volume  the driving system can be applied to aeronautics and astronautics field. With a further improvement  a maximum data output rate of 2.7 frames per second can be reached through all the eight channels of the two CCDs. 2010 Copyright SPIE - The International Society for Optical Engineering.

In the application of TDI-CCD  the other is all kinds of interference noise produced in the working process of a TDI-CCD  for reset noise  because of its serious noise interference  such as reset noise and 1 / f noise  correlated double sampling is employed. The experimental results show that after noise processing  the imaging quality is reduced  etc. According to the features of noise  the output S/N has been raised to about 50 dB. 2010 IEEE.  so that it is necessary to study the noise characteristics of TDI-CCD. There are two categories of noise  this paper has studied the corresponding noise-processing technology. For dark current noise  one is the inherent noise  refrigeration is taken  including shot noise  dark current noise  fixed pattern noise and transfer noise etc.

By using the Correlated Double Sampling (CDS) technique  the video noise is reduced and the SNR of the system is increased. The output rate of the imaging system designed with integrated chip can reach to 1.3 frames per second through bi-channel output. We use the histogram specification to adjust the brightness of the captured image. And then use the median filtering to suppress the noise. The traditional gray mean gradient (GMG) and the objective evaluation method based on Human Visual System (HVS) used to verify the effect of image enhancement. 2010 IEEE.
