Patent number: 11181743Abstract: In relation to a HUD apparatus having an AR function, the shift between an object and a virtual image (AR image) is reduced. The HUD apparatus extracts a predetermined object based on an image taken by an external camera, acquires object information including an object position in space, viewpoint position information of a driver and the amount of movement of the viewpoint position in space based on an image taken by an internal camera, and information including a position of a virtual image region in space. The HUD apparatus generates the image to be superimposed on the object, and corrects a display position of the image in the virtual image region including at least a position in a horizontal direction, and performs conversion processing at the time of the correction so that a virtual image region is set as a display position of the image after correction.Type: GrantFiled: October 12, 2018Date of Patent: November 23, 2021Assignee: MAXELL, LTD.Inventors: Takumi Nakada, Toshimitsu Watanabe, Nozomu Shimoda
