Patent attributes
It is an objective of the invention of the present application to provide an image display apparatus capable of reducing a change in a display state of a virtual image that depends on a change in a viewpoint position. An image display apparatus according to an embodiment of the present technology includes an emission unit, a diffractive optical element, and an emission control unit. The emission unit emits image light of a target image. The diffractive optical element includes an incident surface and an emission surface, diffracts the image light entering the incident surface, emits the image light from the emission surface, and displays a virtual image that is the target image. The emission control unit controls emission of the image light by the emission unit by using image data generated in accordance with a change in a display state of the virtual image that depends on a change in a viewpoint position.
