Image data generation device, display device, image display system, image data generation method, image display method, and data structure of image data

A viewpoint setting unit of an image data generation device sets a reference viewpoint on a basis of position and orientation information regarding a head-mounted display, and a reference image drawing unit generates a reference image in a field of view corresponding to the reference viewpoint. An additional data generation unit acquires color information regarding an occluded part not represented in the reference image from a different viewpoint as additional sampling data. A reprojection unit of the head-mounted display transforms the reference image into an image from a latest viewpoint and determines a pixel value of the hidden part using the additional sampling data.
