Abstract
An image projection device includes: a projection unit that projects an image light beam forming an image onto a pupil of an eyeball of a user to project the image onto a retina of the eyeball; a detection unit that detects a direction in which the pupil has moved relative to a face of the user and a speed of movement of the pupil; and a control unit that performs different controls of the image when the pupil has moved at different speeds in a same direction.
