Our online glossary is here to help you make sense of the terminology used in the cell phone industry. It covers mobile technologies, such as 3G and 4G, and even includes a bit of information on smartphone operating systems and the companies that make the cell phones and other mobile technology devices we all use.

What is "CMOS"?

CMOS is a type of integrated circuit chip manufacturing process that can be used for many things, including digital camera image sensors. CMOS camera sensors are generally cheaper to manufacture than competing CCD based sensors. They 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. Canon, among others, has been using CMOS sensors in their high-end digital SLR cameras for years. Other companies are starting to follow suit. But as it stands today, in terms of mobile phones, most often a device with a CCD sensor will take better images than a comparable CMOS equipped model would.
