An electronic device that includes a display and an eye tracker configured to collect eye tracking data regarding a gaze of one or more of a user's eyes across the display is disclosed herein. The electronic device includes processing circuitry that is operatively coupled to the display and configured to foveate one or more areas of the display according to the eye tracking data. If the eye tracking data input is lost, the processing circuitry is configured to recover from the loss of eye tracking data by changing one or more aspects of the foveated areas (e.g., size, resolution, etc.) until a threshold is satisfied. As time elapses since loss of eye tracking, the foveated areas move toward a center or a salient region of the display.

Recovery from eye-tracking loss in foveated displays

A multi-layer low-pass filter is used to filter a first frame of video data representing at least a portion of an environment of an individual. A first layer of the filter has a first filtering resolution setting for a first subset of the first frame, while a second layer of the filter has a second filtering resolution setting for a second subset. The first subset includes a data element positioned along a direction of a gaze of the individual, and the second subset of the frame surrounds the first subset. A result of the filtering is compressed and transmitted via a network to a video processing engine configured to generate a modified visual representation of the environment.

Gaze direction-based adaptive pre-filtering of video data

An electronic device may include a display panel with pixels that present an image based on image data and an application processor that generates the image data. The electronic device may include a display pipeline coupled to the electronic display and the application processor. The display pipeline may receive first image data from the application processor corresponding to a first color space used by the application processor. The display pipeline may apply a color mapping relationship to the first image data to generate second image data. The color mapping relationship may define a transform to apply to the first image data to generate the second image data corresponding to a second color space used by the electronic display. The display pipeline may transmit the second image data to a display driver that operates the electronic display to emit light according to the second image data.

Efficient color mapping systems and methods

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.

Displays with improved color accessibility

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 may be specific to the type and severity of color vision deficiency that the user has. The control circuitry may conduct a color vision assessment using the display. The color vision assessment may include a sequence of test images that are each displayed for a predetermined period of time before moving to the next test image in the sequence. Each test image may include a color patch on a neutral background. A predetermined number of severity levels for each type of color vision deficiency may be tested during the color vision assessment.
