Optical scanner equipped with plug-in calibration film
View Patent ↗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.
1. 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.
2. The optical scanner claim 1 , wherein the attachment comprises a recess, and the plug-in calibration film is connected with the recess by pasting.
3. The optical scanner of claim 1 , wherein the attachment comprises a gliding groove, of which shape is matched with the plug-in calibration film to provide a displacement motion for the plug-in calibration film inside the gliding groove.
4. The optical scanner of claim 1 , wherein the plug-in calibration film comprises a positive plug-in calibration film.
5. The optical scanner of claim 1 , wherein the plug-in calibration film comprises a negative plug-in calibration film.
6. 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.
7. The method of claim 6 , wherein adjusting comprises adjusting the optical chassis to obtain a desired brightness for the image signals.
8. The method of claim 7 , further comprising executing a scan of a transmission document after the adjusting.
9. The method of claim 7 , wherein the calibration film comprises a positive calibration film.
10. The method of claim 7 , wherein the calibration film comprises a negative calibration film.
11. The method of claim 7 , wherein the optical chassis comprises a portion of an optical scanner.
