Abstract: A head-mounted device may include a camera that captures a live video feed of an environment. A display in the head-mounted device may display passthrough display content that includes the live video feed. Control circuitry may dynamically adjust a maximum allowable brightness for the passthrough display content during operation of the head-mounted device. Upon an initial donning of the head-mounted device, the passthrough display content may be permitted to use most or all of the achievable brightness range of the display. After a given time period, the user may be adapted to the brightness range of the display and the maximum allowable brightness for the passthrough display content may be reduced to allow additional headroom for rendered display content. The control circuitry may continue to adjust tone mappings for passthrough display content and rendered display content based on whether the display content favors real-world content or virtual content.
