Abstract:
1. A mixed reality presentation system including: a head mounted display having an imaging unit which senses an image of a physical space, and a display unit which displays an image; and an image processing apparatus which generates an image to be displayed on the display unit, wherein said head mounted display comprises: a composition unit which generates a composition image by compositing a physical space image sensed by the imaging unit and a virtual space image, the virtual space image including a virtual object and being transmitted from said image processing apparatus; a unit which acquires position and orientation information indicating a position and orientation of a viewpoint; and a transmission unit which transmits the acquired position and orientation information to said image processing apparatus, and said image processing apparatus comprises: a reception unit which receives the position and orientation information transmitted by said transmission unit; a derivation unit which derives a generation completion time of the virtual space image on the basis of amount of data of the virtual object, wherein a larger amount of data results in a later derived generation completion time; a prediction unit which predicts a position and orientation of the viewpoint at the derived generation completion time, using the derived generation completion time and the received position and orientation information; a generation unit which generates a virtual space image including the virtual object based on the viewpoint having the position and orientation predicted by said prediction unit; and a unit which transmits the virtual space image generated by said generation unit to said head mounted display.
