CMOS image sensor technology has turned into the new normal. Well, not entirely... For high-end resolutions above 50 Megapixels, users still require CCD imagers to acquire high-resolution images. But now, CMOS sensors are available with high and super-high resolution, and bring numerous benefits for developers of demanding applications in terms of quality, speed, pricing, and time-to-market.
Clearly, from an end user experience, a noisy image is not a good image. This is an issue made more difficult because of the high sensitivity of the eye for the smallest of deviations. Also, for algorithms, noise leads to more efforts in analysis and less accuracy. For a camera manufacturer, the noise contains a plethora of information about the sensor and the electronic driving it. Thus, the noise is a developer’s best friend and if carefully analyzed will lead to the best possible camera design and implicitly to the best possible image for a given sensor and electronic components.
