CMOS is a type of integrated circuit chip manufacturing process that can be used for many things, including digital camera image sensors.hey also require less power to use than do CCD sensors, which makes them popular in mobile devices. The drawback to CMOS sensors when used in cameras is that they tend to create photographs with a lot of image noise when used in lower light situations, though this is not always the case.
CMOS uses a slightly different technology from CCD, another type of image sensor found in digital cameras. CMOS is becoming the more popular type of technology because of its low power consumption and speed.Also Known As: complementary metal-oxide semiconductor sensor.he complementary metal-oxide semiconductor (CMOS) sensor consists of millions of pixel sensors, each of which includes a photodetector. As light enters the camera through the lens, it strikes the CMOS sensor, which causes each photodetector to accumulate an electric charge based on the amount of light that strikes it.
