Abstract:
The present invention relates to a document scanning apparatus which is composed of an automatic document feeding device and an image capturing device. The document scanning apparatus establishes a private area network between the automatic document feeding device and the image capturing device, and causes the automatic document feeding device to send a message to the image capturing device. When the message is received, said image capturing device performs corresponding operations in response to the message. Said operations may comprise, for example adjusting the relative position between the image capturing device and the automatic document feeding device or doing multi-documents scan.

Claim (Index 17):
The scanning method as claimed in  claim 11 , performs the following operations when the message comprises an information of the automatic document feeding device being ready to feed documents, and the quantity of feature points caotained in the message being larger than a threshold:\n controlling a image capturing unit to capture images of documents passing through the scanning position and temporarily store into a native image linkage; extracting images of documents stored in the native image linkage, checking errors of exposure, focus and skew of the images of documents, and suspending the photography of the image capturing unit to readjust parameters of the image capturing unit when at least one of the errors being detected; extracting document images stored in the native image linkage, readjusting image contrast of the images of documents, cropping needed image blocks from the images of documents, temporarily storing the image blocks into a cropped image linkage and deleting the images of documents stored in the native image linkage; determining feature points in the images of documents, calculating the quantity of the feature points and performing corresponding operation according to the quantity of feature points; and extracting image blocks temporarily stored in the cropped image linkage, searching for same feature points existing in different image blocks and using the same feature points to stitch different image blocks into a full-page document image.
