IMAGE DISPLAY DEVICE AND IMAGE DISPLAY METHOD, IMAGE OUTPUT DEVICE AND IMAGE OUTPUT METHOD, AND IMAGE DISPLAY SYSTEM

摘要

[Object] To provide an image display system that displays an image with a wide field of view while reducing VR sickness. [Solution] When a field of view FOV O of an original image provided by an image output device (200) is greater than a field of view FOV D of an image viewed by a user wearing an image display device (300), the image output device (200) cuts out a region with the field of view FOV D from the original image for delivery to the image display device (300). Also, when the field of view FOV O of the image viewed by the user wearing the image display device (300) is equal to or greater than the field of view FOV D of the original image provided by the image output device (200), the image output device (200) delivers the original image as-is to the image display device (300).
