You guys really don't know what you're talking about contextually. If a camera is a '16 megapixel camera', it means the final images it produces (on high quality), will contain approximately 16 million pixels. Likewise, a 16 mp sensor, will produce images containing approximately 16 million pixels.
A fuji F200 EXR point and shoot, for instance, is at least 12mp in normal mode, but drops to 6mp in 'exr' mode, where the sensor doubles up pixels and then interpolates, gathering more light, and producing a 6mp image in the process. You will notice that megapixel, by the makeup of the very word itself, refers to pixel count. It refers to the final image, however, in the context of digital cameras. Make sense? Frank is absolutely incorrect -at least contextually.
