摘要：
The present invention relates to a compensation method for compensating digital image data generated from a scanning module of a scanner when the luminance of a lamp tube is unstable. Several compensating gains are computed according to the luminance values of a reference white plate so as to compensate the digital image data. The method of the present invention is implemented by software in a computer.
