Disclosed is an improved method for determining a default value to use in image background compensation. This method asserts that the default background value of a document has a high probability of being the same as others in a copy set. Thus, if the background value of a previously scanned document is saved, it can be used as the default background value for a subsequent document. The default background value is required during the time that the image value is being compiled for its histogram, or in the case that the background value is out of norm.
