Abstract
A display system (100) includes a rendering image generation unit (120), a parameter computation unit (140), and a warp processing unit (130). The parameter computation unit (140) computes a latency compensation parameter for compensating a latency including a rendering processing latency of a rendering image based on tracking information. The warp processing unit (130) performs latency compensation processing for compensating the position of a virtual object in a display region based on the latency compensation parameter.
Claims18
A display system of a head up display that displays, in a display region, a virtual object corresponding to a real object in the real space, the display system comprising:
- a rendering image generation unit configured to generate a rendering image including the virtual object;
- a parameter computation unit configured to compute a latency compensation parameter for compensating a latency including a rendering processing latency of the rendering image based on tracking information that is at least one of first tracking information of a mobile body in which the head up display is mounted, second tracking information of a viewer of the head up display, and third tracking information of the real object;
- and
- a warp processing unit configured to generate a display image to be displayed in the display region by performing warp processing in which coordinate transformation is performed on the rendering image according to a curve of the display region,
- wherein the warp processing unit performs, in the warp processing, latency compensation processing for compensating the position of the virtual object in the display region based on the latency compensation parameter.
A display method of a head up display that displays, in a display region, a virtual object corresponding to a real object in the real space, the display method comprising:
- generating a rendering image including the virtual object;
- computing a latency compensation parameter for compensating a latency including a rendering processing latency of the rendering image based on tracking information that is at least one of first tracking information of a mobile body in which the head up display is mounted, a second tracking information of a viewer of the head up display, and a third tracking information of the real object;
- and
- generating a display image to be displayed in the display region by performing warp processing in which coordinate transformation is performed on the rendering image according to a curve of the display region,
- wherein, in the warp processing, latency compensation processing for compensating the position of the virtual object in the display region is performed based on the latency compensation parameter.
