An image composition unit outputs a composition image of a physical space and virtual space to a display unit. The image composition unit calculates, as difference information, a half of the difference between an imaging time of the physical space and a generation completion predicted time of the virtual space. The difference information and acquired position and orientation information are transmitted to an image processing apparatus. A line-of-sight position prediction unit updates previous difference information using the received difference information, calculates, as the generation completion predicted time, a time ahead of a receiving time by the updated difference information, and predicts the position and orientation of a viewpoint at the calculated generation completion predicted time using the received position and orientation information. The virtual space based on the predicted position and orientation, and the generation completion predicted time are transmitted to a VHMD. |
