ISO 9241-392:2015制定了减少在规定的观看条件下观看立体图像时可能出现的视觉不适和视觉疲劳的建议。视觉疲劳和不适可能是由双眼呈现的不同图像的立体光学刺激引起的。 ISO 9241-392:2015也适用于立体展示的最终产品，其取决于在适当定义的条件下观看时的立体图像内容和立体显示。因此，这些建议适用于负责设计、开发和提供立体图像内容以及立体显示器的人员。 注1:适当的观察条件见附录B。 ISO 9241本部分中的建议适用于立体显示器，例如带眼镜和双屏幕的显示器- 查看自动立体显示器、立体头戴式显示器和立体投影仪。此外，它们适用于意图在上述立体显示器上呈现的立体图像内容，以及通过这些图像和显示器的组合实现的立体呈现。 注2:附录C提供了数字标准作为参考资料。 注3:当需要特定于每种类型的立体图像内容或立体显示的要求和建议时，可能需要参考ISO 9241的本部分来制定其他指南。 注4:国际电联通常制定广播标准。 注5 ISO 9241？303:2011，附录E提供了用于立体头戴式显示器的虚拟显示器指南。

ISO 9241-392:2015 establishes recommendations for reducing the potential visual discomfort and visual fatigue experienced during viewing of stereoscopic images under defined viewing conditions. Visual fatigue and discomfort might be produced by the stereoscopic optical stimulus of disparate images that were presented binocularly. ISO 9241-392:2015 is also applicable to the final products of stereoscopic presentations which depend on stereoscopic image content and stereoscopic displays when viewed under appropriate defined conditions. Therefore, the recommendations are intended for people responsible for the design, development, and supply of stereoscopic image content as well as stereoscopic displays. NOTE 1 See Annex B for appropriate viewing conditions. The recommendations in this part of ISO 9241 are applicable to stereoscopic displays such as those with glasses and two-view autostereoscopic displays, stereoscopic head-mounted displays, and stereoscopic projectors. Moreover, they are applicable to stereoscopic image content intended to be presented on the above-mentioned stereoscopic displays and stereoscopic presentations that are realized by the combinations of these images and displays. NOTE 2 Annex C presents numerical criteria as an informative reference. NOTE 3 Other guidance might need to be established by referring to this part of ISO 9241 when requirements and recommendations specific to each type of stereoscopic image content or stereoscopic display become necessary. NOTE 4 ITU generally sets the standards for broadcasting. NOTE 5 ISO 9241？303:2011, Annex E provides guidelines for virtual displays which are intended for stereoscopic head-mounted displays.
