摘要 |
<p>A composite higher resolution image of an object can be obtained by combining or patching together multiple low-resolution camera images to form a composite image having a higher resolution. Each low-resolution camera image represents a subsection of an object (also referred to as "object subsection") to be scanned. For example, each subsection may represent a quadrant of a document page. With the use of a periscope, the image visible to the camera can be shifted to capture images of the various object subsections. Mosaicing techniques are used to combine these camera images into a composite image of the object. This approach to scanning improves the resolution of documents scanned while using existing low cost video cameras. <IMAGE></p> |
