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

摘要

Provided is an image display system which displays a wide viewing angle image while suppressing VR sickness. When the viewing angle FOVO of an original image provided from an image output device (200) is greater than the viewing angle FOVD of an image observed by a user wearing an image display device (300), the image output device (200) cuts out a viewing angle FOVD from the original image and sends this to the image display device (300). Further, when the viewing angle FOVD of the image observed by the user wearing the image display device (300) is greater than or equal to the viewing angle FOVO of the original image provided from the image output device (200), the image output device (200) sends the original image as-is to the image display device (300).
