Abstract:
1. A photo card data generation apparatus for generating data used for a card having a face image, the photo card data generation apparatus comprising: photography means for obtaining a face image by photographing the face of a person; eye position detection means for detecting positions of eye centers in the face image; normalization means for obtaining a normalized face image by normalizing the face image so as to cause a distance between the positions to become a predetermined value; cutting means for cutting a card face image of a predetermined standard size from the normalized face image with reference to the distance between the positions of the eye centers in the normalized face image; data generation means for generating the data for the card having the face image, based on the card face image and personal information of the person from which the face image has been obtained; characteristic value calculation means for calculating at least one characteristic value used for recognizing the positions of the eye centers from the face image, wherein the characteristic value or values are at least one of a gradient vector representing a gradient of density of pixels in the sample images or the face image, color information of the pixels therein, density therein, a characteristic in texture therein, depth information thereof, and a characteristic of an edge therein.
