Abstract: A calibration method of an image scanning system is provided. Initially, differences between adjacent sensing values of a calibration plate are respectively determined and then stored in a memory. Alternately, a difference between a base value and each of the sensing values of the calibration plate is determined and then stored in the memory. When a normal scan action is executed, simultaneously reading each difference from the memory and adding to one corresponding sensing value of image information of an object obtained by the normal scan action. As a result, the memory volume for storing calibration data is reduced and the reading of calibration data is also facilitated.

Abstract: The present invention provides a calibration method and circuit for outputting an average calibration value used in an image-capture apparatus. The calibration circuit comprises difference means accepting a plurality of digital signals from capturing a pixel of a calibration chart. The difference means is for operating each digital signal with subtracting a base value, and whereby filters any aberrant digital signal. Divider means accepts the digital signals for operating each digital signal with dividing a number of scanned times, and whereby prevents an operation of any signal from overflowing. Direct average means accepts the digital signals for summing the digital signals and then divides the number of scanned times, and whereby speeds a calibration operation.

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.
