    Abstract: An electronic device may have components that experience performance variations as the device changes orientation relative to a user. Changes in the orientation of the device relative to the user can be monitored using a motion sensor. A camera may be used to periodically capture images of a user's eyes. By processing the images to produce accurate orientation information reflecting the position of the user's eyes relative to the device, the orientation of the device tracked by the motion sensor can be periodically updated. The components may include audio components such as microphones and speakers and may include a display with an array of pixels for displaying images. Control circuitry in the electronic device may modify pixel values for the pixels in the array to compensate for angle-of-view-dependent pixel appearance variations based on based on the orientation information from the motion sensor and the camera.

    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: This disclosure relates to image capture devices with the ability to perform adaptive white balance correction using a switchable white reference (SWR). In some embodiments, the image capture device utilizes “true white” information to record images that better represent users' perceptions. In other embodiments, the same SWR and camera that dynamically sample ambient lighting conditions are used to determine “true white” in near real-time. In other embodiments, the image capture device comprises a display screen that utilizes the “true white” information in near real-time to dynamically adjust the display. In other embodiments, face detection techniques and/or ambient light sensors may be used to determine which device camera is most closely-aligned with the direction that the user of the device is currently looking in, and using it to capture a “true white” image in the direction that most closely corresponds to the ambient lighting conditions that currently dominate the user's perception.

    Abstract: An electronic device may include a display having an array of display pixels and having display control circuitry that controls the operation of the display. The display control circuitry may adaptively adjust the display output based on ambient lighting conditions. For example, in cooler ambient lighting conditions such as those dominated by daylight, the display may display neutral colors using a relatively cool white. When the display is operated in warmer ambient lighting conditions such as those dominated by indoor light sources, the display may display neutral colors using a relatively warm white. Adapting to the ambient lighting conditions may ensure that the user does not perceive color shifts on the display as the user's vision chromatically adapts to different ambient lighting conditions. Adaptively adjusting images in this way can also have beneficial effects on the human circadian rhythm by displaying warmer colors in the evening.

    Abstract translation: 电子设备可以包括具有显示像素阵列并具有控制显示器的操作的显示控制电路的显示器。 显示控制电路可以基于环境照明条件自适应地调整显示输出。 例如，在较冷的环境照明条件下，例如由日光控制的环境照明条件下，显示器可以使用相当冷的白色显示中性色。 当显示器在诸如由室内光源所主导的环境照明条件较暖的环境照明条件下操作时，显示器可以使用相对温暖的白色显示中性色。 适应环境照明条件可以确保用户在视觉色彩适应不同的环境照明条件时不会察觉显示器上的色彩偏移。 以这种方式自适应调整图像也可以通过在晚上显示温暖的颜色对人类昼夜节律有益。

    Abstract: Systems and methods for reducing or eliminating image artifacts on a dual-layer liquid crystal display (LCD). By way of example, a system includes a first display panel and a second display panel. The system includes a processor coupled to the first display panel and the second display panel, and configured to generate a first image, and to generate a second image to be displayed on the first display panel based on the first image. The processor is configured to interpolate the second image. Interpolating the second image includes adjusting the second image according to a generated objective function bounded by a first constraint. The processor is configured to filter the second image, and to generate a third image to be displayed on the second display panel based on the first image and the second image. The third image is generated to prevent image artifacts on the second display panel.

    Abstract: An electronic device such as a cellular telephone or other device may have a housing with front and rear faces joined by a sidewall. A display may be mounted on the front face. The electronic device may include multiple ambient light sensors such as a front ambient light sensor on the front face and one or more supplemental ambient light sensors on the rear face and/or on the sidewall. The front ambient light sensor gathers a front ambient light intensity measurement and the supplemental ambient light sensor gathers a supplemental ambient light intensity measurement. During operation, control circuitry in the electronic device adjusts the display brightness based on data from the ambient light sensors. The control circuitry may implement power saving restrictions that limit when the supplemental ambient light intensity measurement is taken into account and/or that impose a brightness cap on the display brightness.
