Document Type and Number:
WIPO Patent Application WO/2021/039257
Kind Code:
A1
Abstract:
[Problem] To provide a head-up display device, a display system, and a display method that can display video information of stereoscopic video information generated by an external peripheral device of the head-up display device, by depth. [Solution] A head-up display device 200 comprises an acquisition unit 191, an information conversion unit 192, a display unit 11, a virtual image projection optical system 30, a projection distance change unit 62, and a display determination unit 193. The acquisition unit acquires three-dimensional video information including video information and depth information related to the video information. The information conversion unit converts, on the basis of the depth information, the three-dimensional video information to two-dimensional images according to the depths. The display unit displays the two-dimensional images according to the depths. The virtual image projection optical system converts the two-dimensional images displayed by the display unit to a virtual image and performs projection display thereof. The projection distance change unit periodically changes a projection distance of the virtual image from the virtual image projection optical system. The display determination unit controls the display unit such that a two-dimensional image with a depth corresponding to the projection distance is displayed.
