Abstract

A method for re-forming high contrast image in image system, it includes: Scan an object, and transfer the image in image space into a digital image signal. In which, the object includes correcting board, and its surface includes different gray-scale. The collection composed by every pixel on that object is called object space, and the collection composed by every pixel on image is called image space. Based on the result got from scan correcting board, it generates a basic corrected vector. In which, the basic corrected vector is through optical energy of plurality of adjacent pixels in image space to divide optical energy of 1st pixel in object space by optical energy of plurality adjacent pixels in image space. Get inverse corrected vector, which is used optical energy of 1st pixel in object space presented by linear combination of optical energy of plurality of adjacent pixels in image space. In which, the inverse corrected vector is the coefficient of linear combination. Generate a corrected digital image signal, by that digital image signal multiply with inverse corrected vector.
