| 20130278978 | Method of Automatic White Balance Adjustment For Scanner - A method of automatic white balance adjustment for a scanner is described hereinafter. First, a light source provides a white light to make the scanner scan a document and get an initial image of the document. Secondly, get red, green and blue chromatic values of a background color in the initial image. Next, calculate a factor based on the chromatic values and a calibration value which is stored in a calibration sheet. Lastly, the scanner automatically adjusts a brightness ratio of the red, green and blue lights of the light source according to the factor, and then rescans the document to get a final image which has a processed background color. Therefore, the final image having the background color close to white is in favor of identification. Furthermore, the adjustment is executed in process of the scanner rescanning the document so that omits the step of executing adjustment by software. | 10-24-2013 |
