It's a lot to keep up with, and you may not even know what's going on with the camera in your pocket. If that's the case, don't worry, here's a quick primer an digital camera image sensors—just what you need to know.

There are two major types of image sensors for digital cameras and camcorders: CCD (charged-couple device) and CMOS (complementary metal-oxide-semiconductor, sometimes also known as active pixel sensor). We're not going to get into the really geeky differences, because you don't really need to know or care. What you should know is that higher-end digital SLRs (the big cameras with a removable lens) use CMOS because it's easier to make bigger CMOS sensors; and mobile phones do because CMOS uses less power. That said, most point-and-shoot cameras and most camcorders use the more common CCD sensor...."
