Patent Images
1. A method of outputting search results, comprising the computer implemented steps of:
- recognizing characters in a plurality of document images to produce respective document texts;
determining regions of the document images that correspond to words of the respective document texts;
receiving an input indicating one or more search terms;
retrieving a matching document text from among the document texts based on the one or more search terms, wherein the matching document text includes at least one matching word that matches one of the search terms;
displaying, in a first manner, a matching document image corresponding to the matching document text;
automatically determining a featured region based on the one or more search terms in the matching document image that includes a matching region in the matching document image corresponding to the matching word; and
automatically displaying the featured region in the matching document images in a second manner visually distinct from the first manner, wherein said second manner is not chosen by a user between said automatically determining step and said automatically displaying step.

Abstract
Document texts are produced by recognizing characters in document images by an Optical Character Recognition (OCR) process. When such a document text matches one or more search terms of a query, the corresponding document image is displayed. Regions of the document image, corresponding to words of the document text that match the search terms, are displayed in a visually distinctive manner. The display of the document image may be augmented by displaying a region corresponding to a reference text within the document text in another visually distinctive manner.

3. An apparatus for outputting search results, comprising:
-
an OCR device for recognizing characters in a plurality of document images to produce respective document texts;
means for determining regions of the document images that correspond to words of the respective document texts;
an input device for receiving an input indicating one or more search terms;
a search engine for retrieving a matching document text from among the document texts based on the one or more search terms, wherein the matching document text includes at least one matching word that matches one of the search terms;
