First Claim
Patent Images
1. A method of displaying a document on a display device, the method comprising:
- (a) parsing a source document into a plurality of subsets in response to a user input designating a portion of the source document, one of the subsets representing the designated portion, the plurality of subsets having positions within the source document relative to each other; and
(b) causing at least a portion of each of the plurality of subsets to be displayed on the display device at different resolutions to generate a representation of the document, such that the entire source document is depicted in the representation, such that the plurality of subsets are non-overlapping in the representation, and such that said positions of the subsets relative to each other in the source document are maintained in the displayed representation of the document.

Abstract
A method of generating an output image having a lower resolution than that of a source image is provided. A thinned image is generated by discarding outer pixels of the source image. In parallel with generation of the thinned image, an averaged image is generated, such that each pixel of the averaged image represents an average of a subset of pixels in the source image. A first output image is then generated by subsampling the pixels of the thinned image. A final output image is generated as a function of both the first output image and the averaged image.
