Patent Document ID: 7916948
Application ID: 10585323

Base Claim:
1. A character recognition device, comprising: imaging means for shooting an image; position measuring means for measuring a shooting position of the image to obtain shooting position information indicating the shooting position; direction detecting means for detecting a shooting direction of the image in order to obtain shooting direction information indicating the shooting direction; position corresponding information storage means for storing position corresponding information that is words associated with respective positional information indicating positions of respective places; position corresponding information extracting means for determining, based on the shooting position information and the shooting direction information, a range of a shooting object by the imaging means, and extracting from the position corresponding information storage means position corresponding information associated with positions included in the range; and character recognizing means for recognizing, using the position corresponding information extracted by the position corresponding information extracting means, a character or a character string included in the image shot by the imaging means.

Claim 2:
2. The character recognition device in accordance with claim 1 , comprising: non-corresponding-to-position information storage means for storing therein non-corresponding-to-position information that is words not associated with positional information; and non-corresponding-to-position information extracting means for extracting non-corresponding-to-position information from the non-corresponding-to-position information storage means according to the position corresponding information extracted by the position corresponding information extracting means, wherein the character recognizing means recognizes a character or a character string included in the image using the position corresponding information extracted by the position corresponding information extracting means and the non-corresponding-to-position information extracted by the non-corresponding-to-position information extracting means.
