Abstract:
The method to control a light source in an image scanning apparatus includes emitting light onto a reference surface having a predetermined reflectivity from a light source, detecting a shading level representing an intensity of the light reflected from the reference surface, and controlling the light intensity from the light source by using the shading level and the reference level.
