The paper applies the thoughts of partial differential equations  puts forward a new improved method of image enhancement. This method can enhance not only the dark images but also the bright images  making the details hidden in the dark background and the bright background very clear. The application scope is wider  and the visual effect is better. This paper uses the finite difference method to discrete the partial differential equations  and combines with the heat equation. It calculates simple  runs fast  and provides a guarantee for real-time video image enhancement processing. 2010 IEEE.   Driving and image enhancement for CCD sensing image system (EI CONFERENCE) 会议论文  OAI收割 2010 3rd IEEE International Conference on Computer Science and Information Technology, ICCSIT 2010, July 9, 2010 - July 11, 2010, Chengdu, China Zhang M.; Ren J. 收藏  |  浏览/下载：28/0  |  提交时间：2013/03/25 The paper designs a driving circuit of high sensitive  wide dynamic for CCD sensing imaging system which adopts a Dalsa-made high resolution full-frame 33-mega pixels area CCD FTF5066M. 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 sensor. 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.
