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.
