讨论了工业 X射线照相及照片数字化过程中 ，X射线源及噪声对图像质量的影响 ，建立了图像退化的数学模型 ，并以此为基础 ，给出了复原的算法及处理结果 。
In the process of X ray photography and digitizing of X ray image, the influence of the X ray source and noises on the image quality is discussed in this paper, and a mathematical model is built.
实验结果表明，该方法消除图像脉冲噪声十分有效，对闪光照相CCD图像的处理结果也较好。
The experimental results show that the new method is very efficient to remove the impulse noise. It also can get better result for flash X-ray radiographic CCD image.
它可以拍出非常出色的照片，非常易于使用，是一个非常灵活的联动测距式照相机，但工作噪声比较大，我认为这是G2最大的缺点。
It can take very good photographs. It is easy to use. It is flexible for a rangefinder. It is noisy. This is the worst thing about the G2 in my opinion.
