15. A system for scanning a document, said system comprising: a first image-capture device; an active surface; and a computing system communicatively coupled to said first image-capture device, wherein said computing system comprises a memory storing instructions to be executed by said computing system to: receive an image frame from said first image-capture device; compare said received image frame with a previously captured image frame, wherein said instructions to compare said received image frame with said previously captured image frame comprise instructions to calculate a pixel color difference, at each pixel location in said received image frame, between said received image frame and said previously captured image frame; when said comparison indicates that said received image frame has stabilized relative to said previously captured image frame, determine if said received image frame is associated with a document; and when said determining indicates that said received image frame is associated with a document, capture a document image associated with said image frame to a document buffer.
