    摘要： According to one embodiment, a display apparatus includes a generation unit and a presentation unit. The generation unit is configured to generate a CG image in a CG space having a coordinate system corresponding to a scene viewed from a view point of an observer. The CG image represents a target to be perceived by the observer. The presentation unit is configured to present the CG image to at least one eye of the observer. The generation unit generates a plurality of CG images of the target advancing to a specific coordinate in the CG space and going back from the specific coordinate based on a velocity of the vehicle. The target is perceived by the observer so that the target is advancing from of the vehicle to a specific location corresponding to the specific coordinate in the scene and stops at the specific location for a specific time.
