26、9241-392:2017 (E)3 ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a sub

27、ject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (I

28、EC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be

29、noted.

40、 different retinal image. The fusion of these retinal images by the brain provides a single percept with an associated sense of depth termed as stereopsis. Recent advances in the imaging technology have created a notable increase in our chances of viewing artificially-created stereoscopic images. Th

41、e technology creates two different images, one of which is seen by one eye and the other by the other eye. Their fusion results in the sensation of stereopsis.Stereoscopic images are appealing because of their heightened sense of reality compared with the traditional 2D images. Presentations of ster

42、eoscopic images also provide clear depth information and, for this reason, the broad use of stereoscopic images is anticipated in fields such as medicine and industry. However, there are scientific data indicating that without careful consideration of the properties of the human visual system, the s

43、tereoscopic presentation of images might induce undesirable effects.This part of ISO 9241 describes the basic and minimal conditions for comfortable viewing of stereoscopic images. It is intended to promote an environment in which viewers can enjoy the benefits of stereoscopic images without adverse

44、 effects. In such an environment, new technologies for stereoscopic images can also be actively developed and applied in various fields. This part of ISO 9241 is not intended to restrict the freedom of expression or artistic creativity in the image culture.This part of ISO 9241 is based on scientifi

45、c findings related to the possible undesirable effects of viewing stereoscopic images and in the future, this part of ISO 9241 can be revised as new scientific data.This part of ISO 9241 specifies humansystem interaction standards. Readers who need guidance on other aspects of humansystem interactio

46、n can therefore refer to other documents in ISO 9241 (see Annex A for an overview of the entire ISO 9241 series).DIN EN ISO 9241-392:2017-05 EN ISO 9241-392:2017 (E) 6 1 ScopeThis part of ISO 9241 establishes recommendations for reducing the potential visual discomfort and visual fatigue experienced

47、 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.This part of ISO 9241 is also applicable to the final products of stereoscopic presentatio

48、ns 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
