Image recognition apparatus, image recognition processing method, and image recognition program
First Claim
1. An image recognition apparatus comprising:
- shooting means for shooting an object image to be discriminatively recognized and identified;
a plurality of attribute-classified image database means classified respectively in accordance with a plurality of attributes corresponding to various situations of the shooting performed by said shooting means, and storing therein reference images classified by the attributes and also storing recognition ID attached uniquely to the reference images respectively;
selection means for selecting, from the plurality of attribute-classified image database means, one image database means of the attribute corresponding to the present situation of the face recognition; and
object specifying means for specifying the recognition ID, which corresponds to the object image shot by said shooting means, with reference to the reference image stored in the attribute-classified image database means selected by said selection means.

Abstract
An image recognition apparatus, method and program capable of discriminatively recognizing an object at an enhanced recognition rate despite an increase in the total number of reference images registered in image databases. When any individual person or public corporation for example is to be specified from the object image obtained by shooting the person or the like, one image database of the attribute corresponding to various situations, or familiarity to the object image is selected automatically, and then the person or corporation is specified from the shot image while referring to the reference images stored in the image database of the selected attribute. Therefore, even if the sum of the reference images is increased, since they are subdivided and classified corresponding to the attributes, the number of the reference images for each attribute can be reduced, and further the image database of the optimal attribute can be selected automatically in conformity to the situation of recognition such as date, time and so on. Thus, the number of the reference images can be minimized without the user'"'"'s intentional manipulation, and the reference images are narrowed down due to the additional information of the situation.
