Information processing device, information processing method, and program

An information processing method of an information processing device, said information processing method comprising:

• by the information processing device,
• generating a plurality of registration images assuming a plurality of different lighting conditions at a time of imaging from a registration original image in which a subject to be registered is imaged on a basis of an imaging characteristic of an imaging section;
• extracting respective feature quantities of said plurality of registration images;
• extracting a feature quantity of an identifying object image in which a subject as an identifying object is imaged;
• and
• identifying the subject of said identifying object image on a basis of degrees of similarity between the feature quantity of said identifying object image and the feature quantities of said plurality of registration images.

A program for making a computer function as:

• a registration image generating section configured to generate a plurality of registration images assuming a plurality of different lighting conditions at a time of imaging from a registration original image in which a subject to be registered is imaged on a basis of an imaging characteristic of an imaging section;
• a feature quantity extracting section configured to extract respective feature quantities of an identifying object image in which a subject as an identifying object is imaged and said plurality of registration images;
• and
• an identifying section configured to identify the subject of said identifying object image on a basis of degrees of similarity between the feature quantity of said identifying object image and the feature quantities of said plurality of registration images.
