Temporal noise sets the fundamental limit on image sensor performance. In a CCD image sensor, noise is primarily due to the photodetector shot noise and the output amplifier thermal and 1/f noise. CMOS image sensors suffer from higher noise than CCDs due to the additional pixel and column ...

Noise sources in CMOS sensors differ only in relative magnitude. Neat Image is a remarkable program for reducing noise. Instead of lowpass filtering, the software is trained to recognize the structure of the noise. It can reduce noise with minimal side-effects. Particularly valuable at high ...

显然,数码相机上使用CMOS sensor 成像,而胶片使用乳化的银盐颗粒成像,两者的物理特性是完全不同的,所以单反相机的“颗粒感”是使用软件算法添加噪声模拟出来的结果。 Synthetic Grain After any noise reduction, the image is likely to look a little "off", even if a very light level of noise reduction was...
I am not a CMOS Image Sensor engineer, so I can't get any deeper than that. I would offer, based on the numerous patents I've read that have been published by both Sony and Canon, that there are other reasons why noise increases with exposure time. There are quite a number of noise...
