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.

Abstract: An electronic device may be provided with a display. The display may be configured to display standard dynamic range image content and high dynamic range image content at the same time. The control circuitry may dynamically adjust an amount of headroom for the high dynamic range image content to avoid washing out the standard dynamic range image content. For example, the control circuitry may reduce the amount of headroom available for high dynamic range image content with high average pixel luminance levels and low screen coverage. The headroom may be increased as the average pixel luminance levels decrease and/or as screen coverage increases. Different high dynamic range images that are displayed at the same time may be assigned different amounts of headroom (e.g., different peak brightness levels) based on average pixel luminance values, screen coverage, whether or not the content is within an active window on the display, etc.
