固定图案噪声是微光成像系统的主要噪声之一，它直接导致了微光 图像质量的下降，因此必须予以处理以提高图像的视觉效果。文中通过对微光图像 固定图案噪声的特征及其产生机理进行深入的研究，从数字图像处理的角度阐述 了固定图案噪声的处理方法，提出一种因子加权校正结构并给出其硬件实现。实验 结果表明，通过该方法的处理可以有效地消除微光图像固定图案噪声，提高图像的 质量，增强人眼的视觉效果。
Fixed pattern noise is one of the main noises of the glittering imaging system, which directly leads to the degradation of the glimmer image quality and must be dealt with to improve the visual effect of the image. In this paper, through deep research on the characteristics and mechanism of the fixed pattern noise of the glimmer image, the processing method of fixed pattern noise is elaborated from the perspective of digital image processing, and a kind of factor weighted correction structure is proposed and its hardware implementation is given. The experimental results show that the method can effectively eliminate the noise of the fixed pattern of the glimmer image, improve the quality of the image and enhance the visual effect of the human eye.
