Claim 8:
9. An information processing method comprising:
extracting a key point of a target object, which is distinguished from a feature amount, from an input image as a target key point; and
calculating, as a score of the input image from which the target key point is extracted, an index value related to a reliability of the target key point based on the target key point,
wherein the target object includes an iris of a living body, and the method further comprises:
determining that an eye including the iris is not included in the input image when the score is less than a predetermined first determination threshold value; and
determining that a blinking eye is included in the input image when it is determined that the eye is included in the input image and a time during which the score keeps being less than a predetermined second threshold value is shorter than a predetermined time.
