Abstract
A cost effective and easily assemblable image scanning device with a relatively stable and satisfactory scanning effect is disclosed. The present image scanning device is used in an image scanner having a light source and a focusing reflector device. The image scanner device includes a brightness reflection device for generating a brightness reflection signal in response to a light signal from the light source; an image sense device for respectively generating an image sense signal and a reference brightness signal in response to an object reflection signal from the object to be scanned and the brightness reflection signal; and a brightness-controlling device electrically connected to the image sense device for compensating the image sense signal in response to the reference brightness signal.
