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.
Part of the Microprocessors glossary: CMOS (complementary metal-oxide semiconductor) is the semiconductor technology used in the transistor s that are manufactured into most of today's computer microchip s.n CMOS technology, both kinds of transistors are used in a complementary way to form a current gate that forms an effective means of electrical control. CMOS transistors use almost no power when not needed.
