摘要
An improved shading correction system is disclosed where the light intensity variations of the light sources are sensed and are fed back to the shading correction system for improved shading correction. Such feedback action may be applied both during the recording of shading profile reference values when a reference target is scanned and for shading correction when the actual target is scanned.
