Image resolution

Cameras offer different levels of image quality which is determined by lens quality and the resolution (number of pixels) delivered by the CCD. Basic cameras have VGA resolution CCDs that record images with 640x480 pixels. Next up are SVGA models that record 800x600 pixels and then the XVGA models that create pictures with over 1024x768 pixels. The latest super megapixel models go way beyond these figures – currently creating images up to 3040x2016. If you're buying the camera to take pictures for use on screen you only need to buy a VGA model, but if you demand photo quality you need at least a megapixel variety and even then the quality is only good to about 5x7inch from a normal inkjet printer.
