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 images tend to be higher in noise. CCD sensors are more sensitive to light. CMOS sensors need more light to create a low noise image at proper exposure. This does not mean that CMOS sensors are completely inferior to CCD. CCD has been around for a lot longer in digital cameras, and the technology is more advanced.CMOS sensors are catching up and will soon match CCD in terms of resolution and overall quality.It's only a matter of time before CMOS catches up.CD has been around for a lot longer in digital cameras, and the technology is more advanced.
