Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. Crosstalk between viewing zones and disparity between images received from different viewing zones may result in disparity-caused shifts in images perceived by viewer of the lenticular display. To mitigate these disparity-caused shifts, compensation circuitry may be included in the display pipeline circuitry. The compensation circuitry may include stored disparity-caused shift calibration information that is used for the compensation. The stored disparity-caused shift calibration information may be a polynomial function that outputs a magnitude of disparity-caused shift for a given pixel location.

Abstract: An electronic device may have a camera and a display. The display may be configured to display virtual reality content for a user in which no real-world content from the camera is displayed or mixed reality content in which a combination of real-world content from the camera and overlaid virtual reality content is displayed. Control circuitry in the device may adjust the display and camera while transitioning between virtual reality and mixed reality modes. The control circuitry may reconfigure the camera to exhibit a desired frame rate immediately upon transitioning from virtual reality mode to mixed reality mode. Transitions between modes may be accompanied by smooth transitions between frame rates to avoid visible artifacts on the display. The camera frame rate may be synchronized to the display frame rate for at least part of the transition between the virtual reality and mixed reality modes.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To prevent a visible border between the reduced resolution areas of the display and full resolution areas of the display, uniformity compensation circuitry may be used to compensate pixel data. The uniformity compensation circuitry may output compensated pixel data for the display using one or more compensation maps that include compensation factors associated with pixel locations. The uniformity compensation circuitry may also use region-specific gamma look-up tables to apply different gamma curves to pixels in different regions of the display. The uniformity compensation circuitry may also be used to form a transition region between different regions of the display.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. To mitigate jaggedness in a curved edge of the active area, control circuitry may modify input pixel data for the display using dimming factors. Each brightness value of the pixel data may be multiplied by a corresponding dimming factor such that the curved edge has a smooth appearance. Each physical pixel in the display may have an associated perceived pixel that is based on an appearance of that physical pixel through the lenticular lens film. The perceived pixel may have a different footprint than its corresponding physical pixel. The dimming factors for boundary smoothing in the curved edges may be based on the perceived pixels.

Abstract: An electronic device uses a multidimensional (e.g., 3D) scaler to process multiple-viewing-angle (e.g., 3D-aware) images by resampling each view image and processing image data of each view image according to a view map to change resolution or improve perceived image quality. After being processed, each view image of the multiple-viewing-angle image is used to rebuild a final processed multiple-viewing-angle (e.g., 3D-aware image) with all views for displaying on the electronic device.

Abstract: A mixed reality system that includes a device and a base station that communicate via a wireless connection The device may include sensors that collect information about the user's environment and about the user. The information collected by the sensors may be transmitted to the base station via the wireless connection. The base station renders frames or slices based at least in part on the sensor information received from the device, encodes the frames or slices, and transmits the compressed frames or slices to the device for decoding and display. The base station may provide more computing power than conventional stand-alone systems, and the wireless connection does not tether the device to the base station as in conventional tethered systems. The system may implement methods and apparatus to maintain a target frame rate through the wireless link and to minimize latency in frame rendering, transmittal, and display.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The display may have a number of independently controllable viewing zones. Each viewing zone displays a respective two-dimensional image. Each eye of the viewer may receive a different one of the two-dimensional images, resulting in a perceived three-dimensional image. The electronic device may include display pipeline circuitry that generates and processes content to be displayed on the lenticular display. Content generating circuitry may initially generate content that includes a plurality of two-dimensional images, each two-dimensional image corresponding to a respective viewing zone. Pre-processing circuitry may subsequently anisotropically resize each two-dimensional image. Pixel mapping circuitry may then be used to map the resized two-dimensional images to the array of pixels in the lenticular display.
