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 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: It may be desirable to implement a vignetting effect in a display. The vignetting effect causes the display to have a light-emitting area that gradually fades to a black, non-light-emitting area. The vignetting effect allows for the size and shape of the light-emitting area to be controlled while still being aesthetically pleasing to a viewer. To implement a vignetting mask for the vignetting effect, control circuitry in the electronic device may apply dimming factors to image data for the display. To avoid artifacts caused by the vignetting mask, an initial array of dimming factors for implementing the vignetting mask may have a range between ?0.5 and 1.5. After upsampling, clamping may be performed to reduce the range of the dimming factors to between 0 and 1. Ultimately, the dimming factors are applied to image data for each frame to implement the vignetting mask in each frame.
