Abstract

A dynamically tinted display visor (DTDV) is disclosed. In embodiments, the DTDV includes a visor surface having an untinted or substantially transparent setting and a tinted or substantially opaque setting. The visor surface is fixed to a helmet worn by an operator (e.g., a pilot or co-pilot), the helmet further including a head tracking system for monitoring the head pose (e.g., head position and orientation) of the operator. Helmet-mounted cameras include auto-gain sensors capable of assessing ambient light levels consistent with the head pose of the operator. The DTDV includes a tint processor for adjusting the tint setting of the visor surface based on an assessment of the head pose data and sensed ambient light levels, automatically detinting or darkening the visor as conditions demand or manually detinting/darkening at the operator's command.
