Search engines and systems with handheld document data capture devices

1. A method performed by a mobile device, the method comprising:

receiving an image optically captured from a textual portion of a rendered document;

determining multiple text strings from the image;

generating multiple search queries, each search query comprising a respective one of the multiple text strings;

sending the multiple search queries to an Internet search engine at a location remote from the mobile device;

receiving, at the mobile device and from the Internet search engine, multiple respective sets of search results determined by the search engine in response to the respective search queries;

determining from the multiple respective sets of search results a first search result that most likely identifies an electronic content counterpart of the rendered document; and

providing, for output, the first search result.

2. The method of claim 1 , wherein the search results include an indication of electronic content corresponding to the rendered document.

3. The method of claim 1 ,

wherein the search results include one or more actions associated with the rendered document, and

wherein displaying the first search result comprises displaying a menu of the one or more actions associated with the rendered document.

4. The method of claim 3 , wherein the one or more actions include at least one action selected from the group consisting of: purchasing a product, reviewing a product, linking to an associated web site, retrieving at least a portion of an electronic counterpart to the rendered document, associating annotations with the rendered document, and retrieving a translation of an electronic counterpart to the rendered document.

5. The method of claim 1 , wherein the search results include markup data associated with an electronic counterpart to the rendered document, and wherein the method further comprises:

optically capturing a portion of the rendered document;

determining that the captured portion of the rendered document corresponds to a portion of the electronic counterpart to the rendered document that is associated with the markup data; and

performing one or more functions that are associated with the markup data.

6. The method of claim 5 , wherein the markup data includes an advertisement for presentation in response to capturing the portion of the rendered document.

7. The method of claim 5 , wherein the markup data includes a multimedia annotation for presentation in response to capturing the portion of the rendered document.

8. The method of claim 5 , further comprising storing the markup data in a memory of the mobile device.

9. A non-transitory computer readable medium having stored therein instructions, that when executed by a computing device, cause the computing device to perform functions comprising:

receiving an image optically captured from a portion of a rendered document, wherein the portion at least partially includes text;

determining multiple text strings from the image;

generating multiple search queries, each search query comprising a respective one of the multiple text strings;

sending the multiple search queries to an Internet search engine at a location remote from the computing device;

receiving, at the computing device and from the Internet search engine, multiple respective sets of search results determined by the search engine in response to the respective search queries;

determining from the multiple respective sets of search results a first search result that most likely identifies an electronic content counterpart of the rendered document; and

providing, for output, the first search result.

10. The non-transitory computer readable medium of claim 9 , wherein the search results include an indication of electronic content corresponding to the rendered document.

11. The non-transitory computer readable medium of claim 9 , wherein the search results include one or more actions associated with the rendered document, and

wherein displaying the first search result comprises displaying a menu of the one or more actions associated with the rendered document.

12. The non-transitory computer readable medium of claim 11 , wherein the one or more actions include at least one action selected from the group consisting of: purchasing a product, reviewing a product, linking to an associated web site, retrieving at least a portion of an electronic counterpart to the rendered document, associating annotations with the rendered document, and retrieving a translation of an electronic counterpart to the rendered document.

13. The non-transitory computer readable medium of claim 9 , wherein the search results include markup data associated with an electronic counterpart to the rendered document, and wherein the functions further comprise:

optically capturing a portion of the rendered document;

determining that the captured portion of the rendered document corresponds to a portion of the electronic counterpart to the rendered document that is associated with the markup data; and

performing one or more functions that are associated with the markup data.

14. A system in a mobile device, the system comprising:

a capture component configured to optically capture text of a rendered document;

an optical character recognition component configured to determine multiple text strings that correspond to the captured text;

a query generation component configured to a generate multiple search queries, each search query comprising a respective one of the multiple text strings;

a query transmission component configured to transmit the generated multiple search queries to an Internet search engine at a location remote from the mobile device;

a results reception component configured to receive multiple respective sets of search results matching the generated respective search queries, wherein the search results comprise a first search result that most likely identifies an electronic content counterpart of the rendered document; and

a display output component configured to provide output data for display of at least the first search result.

15. The system of claim 14 , wherein the search results include an indication of electronic content corresponding to the rendered document.

16. The system of claim 14 , wherein the search results include one or more actions associated with the rendered document.

17. The system of claim 16 , wherein the output data includes data for providing display of a menu of the one or more actions associated with the rendered document.
