Abstract
A scanner capable of executing a static calibration and a compensation value adjustment method therefor are disclosed. The scanner includes a calibration piece, a memory, an image capturing unit and a processing unit. The image capturing unit acquires an initial scanned pixel data. A compensation offset-ratio data having a first offset-ratio average is generated according to the initial scanned pixel data and a standard compensation data by the processing unit. Plural selected pixels are determined according to the compensation offset-ratio data, the first offset-ratio average and the predetermined compensation threshold value. A second offset-ratio average is obtained by removing the compensation offset-ratio values of the compensation offset-ratio data of the selected pixels. The initial scanned pixel data is transformed into a static compensation pixel data according to the second offset-ratio average and the standard compensation data.
