Cyclostationary method is not sensitive to the Gaussian color noise and can do with non Gaussian color noise as well, which is proved to be effective in low SNR environment.

循环平稳处理方法对高斯色噪声不敏感，对非高斯色噪声也有较强的抑制作用，而且在低信噪比情况下工作良好。应用于低信噪比环境中。

With SSDR, the HD cameras and automatically increase the brightness of the dark areas of the image without affecting the rest of the image, while SSNR III drastically reduces image noise to provide impressive color in low-light conditions.

They found the unit does indeed impress in its 9-stop expanded dynamic range, beautiful color and excellent noise control yet that range is accompanied by some serious drawbacks, including "glacially slow" shooting and writing speeds and mediocre autofocus which is particularly weak in low lighting situations.

Because the needs of the advanced amateur varies widely, the new CMOS sensor provides a wide ISO range from 100-6400 (expandable from 50-25, 600) to give photographers maximum low-light flexibility yielding clean images with minimal noise and accurate color.
