Abstract: An electronic device may include a display that displays virtual reality content. Control circuitry may estimate a brightness adaptation state of a user that is wearing the electronic device. The control circuitry may select a tone mapping curve and brightness level for the virtual reality content based on the user's adaptation state. To estimate the user's adaptation state, the control circuitry may gather ambient light information from an ambient light sensor, may gather physiological attributes of the user such as blink rate, pupil size, and eye openness from a camera, and may gather gaze position information from gaze detection circuitry. The control circuitry may optimize the brightness of the display based on the user's current adaptation state, or the control circuitry may shift the brightness of the display away from the user's adaptation level to help guide the adaptation state to the desired level.

Abstract: An electronic device may be provided with a display. The display may include a backlight having an array of locally dimmable light sources. Control circuitry may provide control signals to the backlight to produce light at different brightness levels. When the brightness level is below a threshold, the control circuitry may use pulse-width-modulation control signals to control the light sources in the backlight. When the brightness level is above the brightness threshold, the control circuitry may use analog control signals to control the light sources in the backlight. The control circuitry may adjust the threshold to achieve different dimming ranges for different brightness settings. A low brightness setting, for example, may have a lower threshold and lower dimming range than a high brightness setting, which may help produce darker darks when the display operates in a low brightness setting.

Abstract: The present disclosure generally relates to user interfaces for managing exposure compensation when capturing media (e.g., an image, video), displaying representations of media (an image, video), and displaying a status indicator (e.g., status indicator indicating that media is and/or has been captured).
