An image projection apparatus comprising:
- an information acquisition unit configured to acquire information;
- and
- a projector configured to project an image,
- wherein the projector has a projection state in which the projector projects the image based on the information acquired by the information acquisition unit and a non-projection state in which the projector does not project the image, and
- wherein, in accordance with information based on a speed of a vehicle acquired by the information acquisition unit, when a traveling speed of the vehicle is higher than a set speed, a correction processing of the image is turned off, and when the vehicle stops or the traveling speed is lower than the set speed, the projected image is corrected based on a road surface state and/or a reflectance of a road surface acquired by the information acquisition unit.
