摘要：
Aim: In order to reduce the noise of scientific grade CCD camera and improve the image quality. Methods: The noise characteristic of CCD image sensor analyzed. Noise suppression method and signal processing circuit are described and designed analyzed. Results: The circuit can reduce the dark current noise and eliminate the reset noise effectively. Conclusion: Experiments prove that the presented method can reduce noise, increase signal-to-noise ratio and improve image quality.
