ACCURATELY EXTRACTING INFORMATION USING MULTIPLE IMAGES

During an information-extraction technique, a user of the electronic device may be instructed by an application executed by an electronic device (such as a software application) to point an imaging sensor, which is integrated into the electronic device, toward a location on a document. For example, the user may be instructed to point a cellular-telephone camera toward a field on an invoice. After providing the instruction, the electronic device captures multiple images of the document by communicating a signal to the imaging device to acquire the images. Each of these images has an associated exposure setting with a different point of interest proximate to the location). Then, the electronic device stores the images and the points of interest. Furthermore, the electronic device analyzes the images to extract the information proximate to the location on the document.
