This leads to a lower resolution resulting in lower image quality.

If you plan to use the camera for sports tape, 20x or 25x optical is the best.
What is CCD?

Each page is a picture element of the overall picture, and that forms is called a graphic or "pixels". More common in the CCD cameras and other devices that have found retail, an array of pixels, a few hundred pixels wide from a few hundred pixels wide (eg 500×300, or 320×200) is giving tens of thousands of pixels.
