1. An electronic apparatus comprising:
a camera configured to generate an image; and
a processor configured to execute the instruction to:
detect an eye area corresponding to an eye of a user in a first frame of the image;
determine an attribute of the eye area based on an attribute classifier pretrained to output a classification result including an attribute component;
select an eye tracker from a plurality of different eye trackers, the eye tracker corresponding to the determined attribute of the eye area; and
track the eye of the user in a second frame of the image based on the selected eye tracker, the second frame being subsequent to the first frame,
wherein the plurality of eye trackers comprise:
a first eye tracker configured to process an input image of a first attribute including reflection of light;
a second eye tracker configured to process an input image of a second attribute including sunglasses in addition to the input image of the first attribute; and
a third eye tracker configured to process an input image of a third attribute in addition to the input image of the first attribute and the input image of the second attribute.
