We can divide the colored noise into stationary colored noise and non-stationary colored noise by their sensor noise power and the relativity between their sensor noise.

按照阵元噪声功率是否相等以及阵元间噪声的相关性，本文将色噪声分为空间平稳色噪声以及空间非平稳色噪声。

The result shows that when the mean root square of sensor noise is less than 10m, TERCOM algorithm can achieve matching probability of 90%, while the CEP of SITAN is 60~70 meters.

试验结果表明，当传感器噪声的均方根小于10米时，TERCOM算法可以获得大于90%的 匹配概率，SITAN算法也可以达到60~70米的CEP圆概率 误差。

By combining a state-of-the-art image processing engine and back-illuminated CMOS image sensor with low-noise, even up to ISO 6400, and approximately 16.0 effective megapixels, the PENTAX X-5 provides users with very high-resolution images.

Color accuracy was quite good in all situations, and its massive sensor did its job keeping noise to a minimum all the way up to its native max ISO 25, 600.

The Leica M8 doesn't just have a pretty body, nor is it resting on the laurels of its predecessors: it's got a 10.3 megapixel resolution, with a low-noise CCD image sensor that starts at ISO 160 but that can also kick up to ISO 2500.
