标准摘要
[中文适用范围]： ISO 9241 的本部分提供了在观看电子显示屏图像时减少光敏性癫痫发作 (PSS) 的要求和建议。ISO 9241 本部分中的要求和建议旨在应用于图像内容。图像内容指的是独立于显示设备或环境的图像。ISO 9241 本部分中的要求和建议旨在保护观看人群中对光敏感的弱势群体，他们容易因闪光和规则图案（包括某些重复图像）而引发癫痫。 [外文原描述]： ISO 9241-391:2016 provides requirements and recommendations for reducing photosensitive 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. 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 described in ITU-R BT.1702.[2] NOTE 2 There are some related recommendations in ISO/IEC 40500:2012, W3C Web Content Accessibility Guidelines (WCAG) 2.0, for web contents accessibility. NOTE 3 Photosensitive seizures and photosensitive epilepsy, that is, chronic conditions characterized by those repeated seizures are medical conditions. Clinical aspects of photosensitivity appear in Annex C. Visually induced seizures are equivalent to PSS.
