| 摘 要： | 根据CCD器件的工作原理，对CCD图像的噪声组成进行分析，建立了较为完整的泊松-高斯噪声模型，并根据实际的应用情况进行合理的简化，取得了良好的应用效果。采用最大相似估计法对CCD图像的成像模糊进行相应的补偿，并完成了对模型的简化，最后给出了实例。

| Abstract: | The analysis for the noise composition in CCD image is carried out according to the operating principle of CCD device. A complete Poisson-Gaussian noise model is set up, a reasonable simplification has been carried out according to the practical application cases and good application effects have been achieved. The corresponding compensation is implemented for the fuzzy case appeared in CCD imaging by use of maximum-likelihood estimate in the paper. The simplification for the model is finished and the practical case is given in the end. |
