Abstract: A super-resolution scanning display. The scanning display includes a light source, a conditioning assembly, and a scanning mirror assembly. The light source is configured to emit source light from a plurality of columns of emitters formed along a first dimension, including at least a first column of emitters emitting in a first band of light and a second column of emitters emitting in a second band of light which are offset along the first dimension by a fraction of an emitter width and offset along a second dimension—that is orthogonal to the first dimension—by greater than the emitter width. The conditioning assembly receives and conditions the source light. The scanning mirror assembly scans the conditioned light along the second dimension to generate a portion of an image at a first location with a resolution that is more than a first threshold number of emitters in a unit angle in the first dimension.

Abstract: In one example, an apparatus comprises: multiple distinct sets of photodiodes, wherein each set of photodiodes includes one or more photodiodes, one or more charge sensing units, and a controller. The controller is configured to: transfer charge generated by the one or more photodiodes in response to a different component of incident light to the one or more charge sensing units in order to convert the charge to voltages; perform one or more quantization processes of a plurality of quantization processes corresponding to a plurality of intensity ranges, wherein the one or more quantization processes quantizes the voltages from the one or more charge sensing units to digital values representing components of a pixel of different wavelength ranges; and generate a pixel value based on the at least some of the digital values.

Abstract: A method for correcting artifacts in artificial reality headsets is provided. The method includes coupling a first image portion into a waveguide in a display for an artificial reality device, provided by a first array of pixels, coupling a second image portion into the waveguide in the display, provided by a second array of pixels, directing the first image portion through an eyebox, directing the second image portion through the eyebox, and tiling, in a user's retina, the first image portion and the second image portion to form an image having an extended field of view that includes an overlapping area comprising light provided by the first array of pixels and the second array of pixels. A system including a memory storing instructions and a processor to execute the instructions to cause the system to perform the above method are also provided.

Abstract: Disclosed herein are related to a system and a method of remotely rendering artificial reality. In one approach, a console determines an expected transmission end time of a first session for wireless transmission of image data indicating an image of artificial reality to a head wearable display. In one approach, the console determines an expected process end time of generating additional data associated with the image of the artificial reality. In one approach, the console compares the expected transmission end time and the expected process end time. The console may transmit, to the head wearable display in the first session, the additional data together with the image data, in response to the expected process end time being less than the expected transmission end time.
