This is not a true 10 megapixel webcam, it's only 10 megapixels interpolated.
In basic english terms, the image of the camera is blown up and magnified using driver software to a ten megapixel resolution. However the camera's CMOS sensor itself might not even be anything close to say, 2 megapixels.
After the image is taken, the software driver takes a guess as to what the picture should look like at a ten megapixel resolution and then adds extra pixels in order to increase the resolution of the image.
This article probably explains it much better than i can.
