Abstract: The present invention provides a method and apparatus for increasing a scanning resolution. The present invention is applied in optics input equipments, such as scanners and multi-function peripherals. The scanning method projects a light to an original to produce a first image and then focuses the first image with a magnification M to generate a second image The second image is reflected from reflectors to the scanning module to process the scanning. The resolution of the image scanned by the scanning module is M times of a native resolution of the scanning module.
