40、ology enables us to watch high-definition images, some of which can be stereoscopic. When those images are projected onto the retina of both eyes and processed as visual information, undesirable biomedical effects, such as photosensitive seizures, visually induced motion sickness, and visual fatigue

41、 from stereoscopic images can be induced. These undesirable biomedical effects need to be reduced where feasible. The prevention of these undesirable biomedical effects on human health has been referred to as “image safety”.Image safety was first discussed by the ISO in the ISO/COPOLCO with respect

42、to the users of image products. Then, in 2004, the ISO/International Workshop on Image Safety was held and resulted in the publication of ISO/IWA 3:2005 as the international workshop agreement.1Following those discussions, the study group (ISO/TC 159/SC 4/SG on Image Safety) continued to evaluate st

43、rategies of the international standardizations until 2009. The basic concept of Image Safety is common with ISO/IEC Guide 71:201418, in which the idea is that accessibility to and usability of products and services should be available to all people.This part of ISO 9241 will help promote the product

44、ion of safer images by reducing the risk of photosensitive seizures, and thereby result in the wider distribution of images that are free from constraints on which consumers can view them. A small proportion of the population is susceptible to seizures and other neurological effects when watching mo

45、tion picture and video content with certain display features. Since these reactions depend on individual susceptibility have been documented with programming viewed through cathode-ray tube (CRT) displays, there is as yet less experience with high-definition displays.This part of ISO 9241 belongs to

46、 a family of human-system interaction standards. Readers who need guidance on other aspects of human-system interaction should refer to the ISO 9241-series.DIN EN ISO 9241 391:2016 10 - -EN ISO 9241-391:2016 (E)7 1 ScopeThis part of ISO 9241 provides requirements and recommendations for reducing pho

47、tosensitive seizures (PSS), while viewing images on electronic displays.The requirements and recommendations in this part of ISO 9241 are designed to be applied to image contents. By image contents, reference is made to the images independent of the device or environment in which they are displayed.

48、The requirements and recommendations in this part of ISO 9241 are for the protection of the vulnerable individuals in the viewing population who are photosensitive and who are therefore liable to seizures triggered by flashing lights and regular patterns, including certain repetitive images.NOTE 1 ITU considers the image safety issues in relation to broadcasting. Some of these are describe
