Abstract
A scanning apparatus includes a scanning module, a calibration plate, and a driving module. The calibration plate includes a first background region for calibrating the brightness of the scanning module and a second background region for intensifying an edge of a document to be scanned. The driving module is used for driving movement of the calibration plate. As a consequence, the scanning light beam from the scanning module is projected onto the first background region or the second background region of the calibration plate. Under this circumstance, the purposes of calibrating the brightness and increasing the image processing efficiency are both achieved. Moreover, since the calibration plate is driven by the driving module to be moved in the direction parallel with said scanning light beam, the purpose of dynamically adjusting the brightness can be achieved.
