1. An image display apparatus, comprising:
a light source that simultaneously emits image display light used to display an image and conjugate light conjugate to the image display light;
an optical system that projects the image display light emitted by the light source onto a pupil of an eye of a user, and that projects the conjugate light emitted by the light source onto a portion around the pupil of the eye of the user;
a detector that detects reflected light that corresponds to the conjugate light projected by the optical system and reflected off the portion around the pupil; and
a controller that controls a position of a display-target image on a basis of the reflected light detected by the detector.
