摘要： A virtual space image generation device 2 generates a virtual space image including a visibility change region in which a visibility changes based on movement of a viewpoint of a user U. The virtual space image generation device 2 includes an image generation unit 14 that generates the virtual space image in which a degree of change in visibility of the visibility change region changes with elapse of time, when the viewpoint of the user U moves. According to the virtual space image generation device 2, the virtual space image that achieves visibility close to that of the appearance of a real space can be generated when the viewpoint of the user moves.

摘要： In a visibility information acquisition device 1, a display control unit 32 displays a first identifier at a first position ahead of a subject S and subsequently displays a second identifier at a second position spaced in the front-back direction from the first position, and moves the viewpoint of the subject S from the first position to the second position. The display control unit 32 then controls the display state of the second identifier according to the transition condition, and causes the visibility of the second identifier to transition from a reference state to an intended state different from the reference state. The visibility information on the second identifier during transition is acquired by an information acquisition unit 34 from the subject S. Accordingly, information required to allow generation of a virtual space image that achieves visibility close to that of the appearance of a real space can be acquired at high accuracy when the viewpoint is moved.

摘要： A virtual space image generation device 2 generates a virtual space image including a visibility change region in which a visibility changes based on movement of a viewpoint of a user U. The virtual space image generation device 2 includes an image generation unit 14 that generates the virtual space image in which a transition completion time period required for transition of a visibility of the visibility change region between a first state and a second state different from the first state changes based on a predetermined condition, when the viewpoint of the user U moves. Accordingly, the virtual space image that achieves visibility close to that of the appearance of a real space can be generated when the viewpoint of the user moves.
