1. An image recognition apparatus comprising: a memory storing instructions; and at least one processor configured to process the instructions to: determine an occlusion pattern of a face in a facial image representing the face by comparing the facial image with a standard facial image representing a standard face; and identify the facial image using a region determined by the occlusion pattern in the facial image; wherein the at least one processor determines the occlusion pattern further on a basis of: a distribution of a reliability on a basis of comparison of small regions included in the facial image with small regions in the standard facial image corresponding to the small regions in the facial image, and a medium region including a group of the small regions within a predetermined range, when a distribution of a reliability of the group of the small regions satisfies a predetermined occlusion condition.
