Title:
HEAD-UP DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/241718
Kind Code:
A1
Abstract:
An object of the present invention is to realize warping control whereby more natural visibility can be ensured for at least one of a depth image (oblique image) in which three-dimensional vision is assumed, and a direct-facing image (standing image) which is preferably displayed so as to face an operator and in which three-dimensional vision is not assumed in principle. When performing warping processing on a depth image AW displayed on an inclined virtual image display surface PS1a, a control unit 190 (or 195) for performing viewpoint position tracking/warping control performs warping control with the outline of an image area of the depth image as a trapezoid in which at least one set of opposite sides are parallel to each other, and, when performing warping processing on a direct-facing image SP, performs warping control with the outline of the image area of the direct-facing image as a rectangle, including a long rectangle or a square.
