Abstract
An optical scanner equipped with plug-in calibration film, which the optical scanner provides light incident upon a transmission-typed document and catches the image signals of the transmission-typed document by an optical chassis. The optical scanner equipped with plug-in calibration film includes a scanning zone and at least one attachment. The scanning zone is capable of providing for placing the transmission-typed document. The attachment is capable of providing a calibration film for enabling the optical chassis to retrieve the image signals so as to improve the image brightness.
Claims11
An optical scanner, comprising:
- a light source to provide light incident upon a transmission document for generating image signals;
- an optical chassis capable of receiving at least a portion of the image signals;
- a scanning zone to position the transmission-typed document;
- a plug-in calibration film coupled to the optical scanner, wherein the plug-in calibration film is configured to transmit at least a portion of the image signals;
- and
- at least one attachment for the plug-in calibration film formed on the optical chassis.
A method, comprising:
- providing light incident upon a plug-in calibration film to generate image signals;
- receiving, at an optical chassis, at least a portion of the image signals;
- and
- adjusting the optical chassis, based at least in part on the received image signals.
