First Claim
Patent Images
1. A method for searching for electronic content, the method comprising:
- receiving, at a search system, a query image captured from a rendered document;
extracting, from the query image, (i) one or more textual keywords, and (ii) one or more non-text-based, image features;
selecting, from among a set of images, one or more result images that have one or more extracted textual keywords that are associated with one or more of the textual keywords that were extracted from the query image;
after the one or more result images that have one or more extracted textual keywords have been selected, selecting, from the one or more result images, a subset of the one or more result images that have one or more extracted non-text-based, image features that are associated with one or more of the non-text-based, image features that were extracted from the query image; and
in response to receiving the query image, providing the subset of the one or more result images that have (i) one or more extracted textual keywords that are associated with one or more of the textual keywords that were extracted from the query image, and (ii) one or more extracted non-text-based, image features that are associated with one or more of the non-text-based, image features that were extracted from the query image.

Abstract
A mobile device searches for electronic content. The mobile device captures an image from a rendered document, and searches for an electronic version of the image using characteristics of the image and using text within the contents of the image. The mobile device receives a result for the search based upon the image characteristics and the text within the context of the image.

10. A system, comprising:
-
logic circuitry, and tangible non-transitory memory containing computer-readable instructions that, when processed by the logic circuitry, cause the system to perform functions comprising; receiving, at a search system, a query image captured from a rendered document; extracting, from the query image, (i) one or more textual keywords, and (ii) one or more non-text-based, image features; selecting, from among a set of images, one or more result images that have one or more extracted textual keywords that are associated with one or more of the textual keywords that were extracted from the query image; after the one or more result images that have one or more extracted textual keywords have been selected, selecting, from the one or more result images, a subset of the one or more result images that have one or more extracted non-text-based, image features that are associated with one or more of the non-text-based, image features that were extracted from the query image; and in response to receiving the query image, providing the subset of the one or more result images that have (i) one or more extracted textual keywords that are associated with one or more of the textual keywords that were extracted from the query image, and (ii) one or more extracted non-text-based, image features that are associated with one or more of the non-text-based, image features that were extracted from the query image. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A non-transitory computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations comprising:
-
receiving, at a search system, a query image captured from a rendered document; extracting, from the query image, (i) one or more textual keywords, and (ii) one or more non-text-based, image features; selecting, from among a set of images, one or more result images that have one or more extracted textual keywords that are associated with one or more of the textual keywords that were extracted from the query image; after the one or more result images that have one or more extracted textual keywords have been selected, selecting, from the one or more result images, a subset of the one or more result images that have one or more extracted non-text-based, image features that are associated with one or more of the non-text-based, image features that were extracted from the query image; and in response to receiving the query image, providing the subset of the one or more result images that have (i) one or more extracted textual keywords that are associated with one or more of the textual keywords that were extracted from the query image, and (ii) one or more extracted non-text-based, image features that are associated with one or more of the non-text-based, image features that were extracted from the query image.
