Claim One:
1. A face recognition apparatus using plural face images, comprising: a non-transitory memory; a face detection unit configured to detect a reference face image from an image for registration; a face feature point calculation unit configured to calculate plural face feature information from a two-dimensional (2-D) frontal face image if the detected reference face image includes the 2-D frontal face image, and storing the calculated plural face feature information in the non-transitory memory; a compared face generation unit configured to generate 2-D plural compared face images based on a size adjustment about a plurality of symmetrical axes of the identical 2-D frontal face image, using the calculated plural face feature information, wherein directions of the 2-D plural compared face images are respectively different from each other, and wherein one side of a symmetrical axis of the identical 2-D frontal face image is increased in size while an opposing side of the symmetrical axis of the identical 2-D frontal face image is decreased in size; and a face recognition unit configured to determine whether an input face image matches the generated 2-D plural compared face images by comparing the input face image with the 2-D plural compared face images.
