Face identification device

There is provided technology which enables to perform face registration of high reliability even using a few images. A face feature value vector extracting section (14) extracts feature value from a registered image of a new registrant to generate a face feature value vector. A virtual face feature value vector generating section (15) converts the face feature value vector using a feature value converter which performs coordinate conversion in a feature value space. Then, a registration information generating section (16) generates face definition information of the new registrant based on an original face feature value vector and a virtual face feature value vector after conversion and registers in a registration information storing section (19).
