IMAGE RECOGNITION DEVICE AND IMAGE RECOGNITION METHOD
First Claim
1. An image recognition device which outputs, as a recognition result, information indicating what an input image is, said image recognition device comprising:
- an image input unit configured to obtain the input image which is a target image to be recognized;
a similar image search unit configured to search out at least one similar image which is similar to the target image obtained by said image input unit from among images generated independently of said image recognition device, stored in a server device accessible via the Internet, and unintentionally obtained;
a keyword extraction unit configured to extract a plurality of keywords which are candidates for a recognition result of the target image, from attached information which is attached to the at least one similar image searched out by said similar image search unit;
a keyword analysis unit configured to determine at least one likely keyword which is likely to be the recognition result of the target image from among the plurality of keywords extracted by said keyword extraction unit by analyzing the plurality of keywords; and
a presentation unit configured to output the at least one likely keyword determined by said keyword analysis unit, as the recognition result of the target image.

Abstract
To provide an image recognition device which eliminates the necessity of managing a database for recognition even in the case of a number of objects to be recognized.
The image recognition device includes: an image input unit (201) obtaining an input image corresponding to a target image to be recognized; a similar image search unit (202) searching out at least one similar image similar to the target image obtained by the image input unit from among images generated independently of the image recognition device, stored in a server device accessible via the Internet, and unintentionally obtained; a keyword extraction unit (203) extracting a plurality of keywords corresponding to candidates for a recognition result of the target image, from attached information attached to at least one similar image searched out by the similar image search unit; a keyword analysis unit (204) determining at least one likely keyword likely to be the recognition result of the target image from among the plurality of keywords extracted by the keyword extraction unit by analyzing the plurality of keywords; and a presentation unit (205) outputting at least one likely keyword determined by the keyword analysis unit, as the recognition result of the target image.

14. An image recognition method for outputting, as a recognition result, information indicating what an input image is, said image recognition method comprising:
-
obtaining the input image which is a target image to be recognized; searching out at least one similar image which is similar to the target image obtained in said obtaining from among images generated independently of said image recognition method, stored in a server device accessible via the Internet, and unintentionally obtained; extracting a plurality of keywords which are candidates for a recognition result of the target image, from attached information which is attached to the at least one similar image searched out in said searching out; determining at least one likely keyword which is likely to be the recognition result of the target image from among the plurality of keywords extracted in said extracting by analyzing the plurality of keywords; and outputting the at least one likely keyword determined in said determining, as the recognition result of the target image. - View Dependent Claims (15)
