Abstract: A free viewpoint video generation unit (24) (generation unit) of an information processing apparatus (10a) generates a free viewpoint video (J) for viewing a 3D model (90M) (3D object) superimposed on background information (92) from an arbitrary viewpoint position. Then, a shadow application unit (27) generates a shadow (94) of a light source generated on the 3D model (90M) according to the viewpoint position based on light source information (93) indicating the position of the light source related to the background information (92) and the direction of the light beam emitted by the light source, depth information (D) (three-dimensional information) of the 3D model (90M), and the viewpoint position, and applies the generated shadow to the free viewpoint video (J).

Abstract: There is provided an image processing device that processes a projection image presented to a plurality of persons at the same time. The image processing device specifies an overlapping area in which fields of view of two or more users overlap based on information on each user, classifies objects included in the overlapping area into a first object group and a second object group, generates a common image common to all users, made up of the first object group, generates individual images different for each user, made up of the second object group, and determines an output protocol for displaying the individual images.
