PROBLEM TO BE SOLVED: To provide an individual identification device that is robust to the change of an illumination condition. SOLUTION: This device is provided with a luminance correcting part 130 which applies shading correction to a face picture obtained by performing affine transformation and normalization of a face area extracted from an input image and also performs the correction so as to make the average and scattering of luminance set values, a reference face picture dictionary part 210 where a normalized face picture to be the reference of a person to be identified is registered, means 140 and 150 which calculates the correlation between the corrected face picture and the registered face picture to detect the correlation value having the highest correlation among correlation operation results, means 160 and 170 which calculate the number of divided screens from a correlation value detected on the basis of a correspondence table between correlation values and the numbers of divided screens and divide the screen, a luminance correcting part 180 which performs correction so that the shading correction and the average and scattering of luminance can be constant in each divided area, and means 190 and 200 which calculate the correlation between the corrected face picture and the registered reference face picture in each divided area and define a reference face picture having the highest correlation among correlation operation results as an identification result. |
