1. An identification model generation apparatus configured to generate an identification model for identifying a person using an image of an eye, the identification model generation apparatus comprising at least one processor or circuit configured to function as:
an acquisition unit configured to acquire the image of the eye and data on an image capture status of capturing the image of the eye,
an inference unit configured to infer a feature amount of the eye based on the image of the eye and the data on the image capture status, and
a learning unit configured to perform learning in the inference unit to approximate the feature amount of the eye obtained from the inference unit to ground truth data that is a ground truth value of the feature amount of the eye corresponding to the image of the eye and the data on the image capture status, and generate the identification model;
wherein the inference unit is a convolutional neural network configured to infer the feature amount of the eye responsive to an input of a combination of the image of the eye and the data on the image capture status.
