    Abstract: An electronic device may include a display and control circuitry that operates the display. The control circuitry may be configured to daltonize input images to produce daltonized output images that allow a user with color vision deficiency to see a range of detail that the user would otherwise miss. The daltonization algorithm that the control circuitry applies to input images may be specific to the type of color vision deficiency that the user has. The daltonization strength that the control circuitry applies to the image or portions of the image may vary based on image content. For example, natural images may be daltonized with a lower daltonization strength than web browsing content, which ensures that memory colors such as blue sky and green grass do not appear unnatural to the user while still allowing important details such as hyperlinks and highlighted text to be distinguishable.

    Abstract: A head-mounted display may display images in eye boxes. Right and left gaze tracking sensors may gather left eye gaze information from a left eye box and right eye gaze information from a right eye box. During operation in a first mode in which the right and left gaze tracking sensors are not impaired, gaze information from the right and left gaze tracking sensors may be used in presenting foveated and distortion-corrected image content on the displays and/or in otherwise operating the left and right displays. During operation in a second mode in which one of the gaze tracking sensors is impaired, gaze information for the impaired sensor may be estimated from gaze information for the unimpaired sensor in combination with an object depth estimate based on depth buffer information, vestibulo-ocular-reflex gain information, and historical information.

    Abstract: Systems, methods, and devices are provided to reduce a likelihood of image burn-in on an electronic display. Such an electronic device may include image processing circuitry and an electronic display. The image processing circuitry may receive image data and analyze the image data for risk of image burn-in and, based at least in part on the analysis of the image data, reduce a risk of image burn-in at least in part by reducing a local maximum pixel luminance value in at least one of a plurality of regions of the image data over time or by reducing a dynamic range headroom of the image data. The electronic display may display the image data with a reduced risk of image burn-in on the pixels of the electronic display.

    Abstract: A head-mounted device may include a display that generates content and an optical system through which the content is viewable. The head-mounted device may include a lighting system that illuminates a periphery of the optical system. When the user places the device on his or her head in a brightly lit environment, control circuitry may operate the lighting system to provide bright illumination to the user's peripheral vision. The lighting system may gradually decrease in brightness until the user transitions from a bright-adapted state to a dark-adapted state. When the user is partially or fully dark-adapted, the lighting system may be turned off and the display may be turned on. In some arrangements, an ambient light sensor may measure ambient light conditions outside of the electronic device and the control circuitry may control the lighting system based on the ambient lighting conditions.

    Abstract: An electronic device may be provided with a display mounted in a housing. Color ambient light sensors may make measurements of ambient light intensity and color through windows in an inactive border region of the display or other portions of the device. The electronic device may process the ambient light measurements based on ambient light information from the ambient light sensors and based on information from additional sensors such as an image sensor, a force sensor, a capacitive touch sensor, a proximity sensor, an orientation sensor, and other devices. Control circuitry in the electronic device may produce reliable ambient light measurements by combining readings from multiple reliable sources and by discarding readings from ambient light sensors that are blocked by a user's fingers or other external objects. Display color cast and intensity may be adjusted based on ambient light information.

    Abstract: An electronic device may have a display and a camera. Control circuitry in the device can gather information on a user's point of gaze using a gaze tracking system and other sensors, can gather information on the real-world image such as information on content, motion, and other image attributes by analyzing the real-world image, can gather user vision information such as user acuity, contrast sensitivity, field of view, and geometrical distortions, can gather user input such as user preferences and user mode selection commands, and can gather other input. Based on the point-of-gaze information and/or other gathered information, the control circuitry can display the real-world image and supplemental information on the display. The supplemental information can include augmentations such as icons, text labels, and other computer-generated text and graphics overlaid on the real world image and can include enhanced image content such as magnified portions of the real-world image.
