Photosensitive epilepsy: new system to "correct" live TV images

14 Jun 2002

According to a report in Broadcast magazine, a new system is under development to detect and 'correct' potential triggers of photosensitive epilepsy in live television images.

Current technology allows for detection of scenes that may trigger seizures in recorded material, but, according to the report, Broadcast Project Research claim their new system will allow broadcasters of news and other live programmes to instantly correct footage that if left unchecked could trigger a seizure in people with photosensitive epilepsy.

Photosensitive epilepsy is the name given to that form of epilepsy in which seizures are provoked by flickering light encountered in everyday life. Both natural and artificial light sources may precipitate seizures, but the commonest trigger appears to be television. Around 3-5 per cent of people with epilepsy are photosensitive.
