Image capture device for extracting textual information

摘要

A digital image capture device, comprising an image sensor and an optical system for capturing digital images, and a program memory storing instructions configured to cause a data processing system to implement a method for extracting textual information from a document containing text characters. The method includes capturing plurality of digital images of the document using the image sensor. Each of the captured digital images is automatically analyzed using an optical character recognition process to determine extracted textual data. The extracted textual data for the captured digital images are merged to determine the textual information for the document, wherein differences between the extracted textual data for the captured digital images are analyzed to determine the textual information for the document.

1. A digital image capture device, comprising:
an image sensor for capturing a digital image; an optical system for forming an image of a scene onto the image sensor; a data processing system; a storage memory; and a program memory communicatively connected to the data processing system and storing instructions configured to cause the data processing system to implement a method for extracting textual information from a document containing text characters, wherein the method includes:
capturing a plurality of digital images of the document using the image sensor, wherein all of the digital images include substantially the same image content;automatically analyzing each of the captured digital images using an optical character recognition process to determine extracted textual data for each captured digital image; andmerging the extracted textual data for the captured digital images to determine the textual information for the document, wherein differences between the extracted textual data for corresponding portions of the captured digital images are analyzed to determine the textual information for corresponding portions of the document; andstoring the textual information in the storage memory.
