Abstract
This disclosure provides a self-contained imaging device that takes digital photographs of portions of documents (such as photos or photo albums) instead of scanning those images. The imaging device uses a lens to zoom in on specific portions of the document that represent images that are to be digitized. Generally speaking, disclosed embodiments utilize a physical device having a housing, a location for retaining or holding an image to be imaged, such as a platen or image conveyance mechanism, a light source and the imaging system (which can be a digital camera). The disclosed device camera provides a low-cost mechanism that can at-once capture a high resolution image without the delays associated with most scanners.
