When it is determined by the magnitude difference determining unit that the third magnitude value is less than the first threshold value, a similarity calculation of the first and second feature points is performed. When it is determined that the third magnitude value is greater than the first threshold value, a magnitude of another feature point of the target image and a magnitude of the first feature point are compared.
