Abstract
A method for scanning a selected target image area of a document includes steps of establishing in a scanner a first optical path by a first focusing lens; using the first focusing lens to preview the document and select from the whole document image a selected image area; moving the first focusing lens out of the first optical path and move a second focusing lens into the optical path to establish a second optical path in the scanner; and using an optical scanning module in the scanner and the second focusing lens to scan the selected image area of the document to obtain the desired target image.

-7. (canceled)
A scanner, comprising:
- a document supporting surface;
- a first lens having a first optical power;
- a first shifting mechanism coupled to the first lens to establish a first optical path between the first lens and a document disposed on the document supporting surface;
- a second lens having a second optical power;
- and
- a second shifting mechanism coupled to the second lens to establish a second optical path between the second lens and a document disposed on the document supporting surface.
An apparatus, comprising:
- means for scanning an object to obtain a first object image;
- means for viewing the first object image;
- means for selecting a localized area of the object from the first object image;
- and
- means for scanning a localized area of the object to obtain a second object image comprising an image of the localized area of the object.
An apparatus, comprising:
- circuitry to control a first lens having a first optical power and a first shifting mechanism coupled to the first lens to obtain an image of an object;
- circuitry to receive a selection of a localized area of the image of the object;
- circuitry to control a second lens having a second optical power and a second shifting mechanism coupled to the second lens to obtain an image of a localized area of the object in accordance with the selection.
An article comprising:
- a storage medium, having stored thereon instructions that, when executed, result in:
- establishing a first optical path between a first lens and an object disposed on a scanner;
- obtaining a first object image of the object;
- displaying a preview image of the first object image;
- selecting a localized area of the object from the displayed preview image;
- establishing a second optical path between a second lens and the object disposed on the scanner;
- scanning a localized area of the object to obtain a second object image comprising an image of the localized area of the object.
