Abstract
The present invention is related to a scanning apparatus which includes a scanning device emitting a light to a scanned target and receiving a reflected light from the scanned target for scanning the scanned target, and a light-adjusting device electrically connected to the scanning means and adjusting the light emitted from the light source in accordance with the reflected light. The scanning apparatus according to the present invention uses the light-adjusting device to make the scanning device capable of scanning objects having various background colors, i.e. various transmission/reflection ratios, so that a high efficiency and a high resolution image can be obtained.
