Abstract
A method for dynamically scanning an image is disclosed. The present invention substantially improves the quality of the image according to specific distribution of the gray levels. In one embodiment, an image is first scanned using a set of parameters to generate a first image. The compositional distribution of the first image is then analyzed. If a predetermined amount of the compositional distribution of the first image does not lie within a predetermined range, then at least one parameter is adjusted. Next, the image is secondly scanned using the adjusted set of parameters to generate a second image. Finally, the first image and the second image are combined or added to generate a composite image so that at least the predetermined amount of the compositional distribution lies within the predetermined range.
