Abstract

An apparatus for capturing a document with a plurality of compression models comprises an image-processing system and an image-capturing system. The image-processing system is for accepting a request of setting the compression models for the document and processing the data of the document according to the compression models, wherein the request is from an exterior electric device connected to the apparatus. The image-capturing system is for capturing the data of the document, and is connected to the image-processing system and comprises multitudes of optic devices. The method for capturing the document with these compression models comprises accepting a request of setting the compression models for the document; capturing the data of the document; and processing the data of the document with these compression models.

Claims

1-12. -12. (canceled)

13. A scanner, comprising:

an image-capturing component adapted to obtain a preliminary scanned image of a document; and

an image-processing component adapted to;

display the preliminary scanned image of said document;

receive a selection of a scanning zone of the preliminary scanned image, wherein the scanning zone comprises less than the entire preliminary scanned image; and

receive a selection of at least one sub-zone of the scanning zone, wherein selection of the at least one sub-zone comprises designation of an arbitrary area of the scanning zone, and wherein selection of a sub-zone further comprises designation of a compression model for the sub-zone, wherein the compression model defines at least one compression ratio.

14. The scanner of claim 13, wherein the image-capturing component is further adapted to scan said document in accordance with the received selection of a scanning zone and at least one sub-zone.

15. The scanner of claim 13, wherein said compression model defines differing compression configurations for at least two portions of the image.

16. The scanner of claim 15, wherein the differing compression configurations comprise at least lossy and lossless compression.

17. An apparatus, comprising:

means for pre-scanning an object to obtain a preliminary scanned image including a scanning zone;

means for obtaining a chrominance and luminance analysis of at least a portion of the scanning zone; and

means for displaying a plurality of user-selectable sub-zones associated with a plurality of user-selectable compression ratios, wherein the sub-zones and compression ratios are determined based at least in part on the obtained chrominance and luminance analysis.

18. The apparatus of claim 17, further comprising means for displaying said plurality of user-selectable sub-zones.

19. The apparatus of claim 17, wherein said plurality of compression ratios comprise at least lossy and lossless compression ratios.

20. An article comprising a storage medium having stored thereon instructions that, when executed, result in:

obtaining a preliminary scanned image of a document;

selecting a scanning zone of the document based on the preliminary scanned image, wherein the scanning zone comprises less than the entire document;

selecting at least one sub-zone of the scanning zone, wherein selecting at least one sub-zone comprises designation of an arbitrary area of the scanning zone, and wherein selecting a sub-zone further comprises designation of at least one compression ratio for the sub-zone; and

scanning the document in accordance with the selected scanning zone and selected at least one sub-zone.

21. The article of claim 20, wherein the instructions, when executed, further result in:

displaying said preliminary scanned image.

22. The article of claim 20, wherein the instructions, when executed, further result in:

providing data corresponding to said scanned document to an external device.

23. The article of claim 20, wherein the instructions, when executed, further result in:

displaying one or more user-selectable scan zones.

24. The article of claim 20, wherein the instructions, when executed, further result in:

designating a combination of lossy and lossless compression ratios for the at least one sub-zone.

25. An article comprising a storage medium having stored thereon instructions that, when executed, result in:

pre-scanning an object to obtain a preliminary scanned image including a scanning zone;

obtaining a chrominance and luminance analysis of at least a portion of the scanning zone; and

displaying a plurality of user-selectable sub-zones associated with a plurality of user-selectable compression ratios, wherein the sub-zones and compression ratios are determined based at least in part on said chrominance and luminance analysis.

26. The article of claim 25, wherein the instructions, when executed, further result in:

determining a combination of lossy and lossless compression ratios as the plurality of user-selectable compression ratios.
