Abstract

Methods for providing search results from visual imagery and operational details of various methods are described.

Claims

1. A method comprising:

upon a start selection at a wireless camera phone, starting recording of a first video of a scene of interest, wherein the scene of interest comprises text;

upon a release selection, ending recording of the first video and sending the first video to a server system, wherein the first video comprises a sequence of images, wherein a first image of the sequence comprises a first portion of the text, and a second image of the sequence comprises a second portion of the text;

extracting the first portion of the text from the first image using a text recognition engine;

extracting the second portion of the text from the second image using the text recognition engine;

generating at the server system a plurality of contexts based on the extracted first and second portions of the text;

querying a database using the plurality of contexts to generate a list of search results; and

transmitting at least a portion of the search results to the wireless phone.

2. The method of claim 1 comprising:

when playing the first video on the wireless camera phone after the sending the list of information services to the wireless camera phone, overlaying a information comprising the list of search results on the first video.

3. The method of claim 1 wherein the search results comprise information services.
