Patent ID: 8390874

Claim:
A method comprising: scanning a document as a whole at a first resolution, using a scanning device, yielding first data of the document at the first resolution; generating, by a computing device, second data of the document at a second resolution from the first data of the document, the second resolution being lower than the first resolution; after generating the second data of the document at the second resolution, segmenting, by the computing device, the document into a plurality of zones, using the second data of the document; for each zone of the document, determining, by the computing device, an optimal resolution for the zone of the document, by applying one or more resolution rules to the zone; where the optimal resolution for the zone is lower than the first resolution, rescanning the zone of the document at a third resolution equal to the optimal resolution, using the scanning device, yielding third data of the zone of the document at the optimal resolution; replacing, by the computing device, the first data of the document at the first resolution that pertains to the zone with the third data of the zone of the document at the optimal resolution that is lower than the first resolution, wherein after performance of the method, the document is at the first resolution for each zone for which the optimal resolution is not lower than the first resolution, and is at the third resolution for each zone at which the optimal resolution is lower than the first resolution.
