  • Patent number: 11100620
    Abstract: Embodiments relate to hue preservation post processing for highlight recovery of an input image. Intensity values for multiple color channels of a plurality of color channels of a pixel of the input image is determined using corresponding ratios of target hues for the plurality of color channels of the pixel, wherein the pixel has at least one color channel with an intensity above a predetermined threshold. A hue preserved value for a color channel of the plurality of color channels of the pixel is determined using intensity values determined for the plurality of color channels of the pixel and the target hues. A recovered version of the input image is generated by adjusting hue information of the pixel, using the hue preserved value for the channel of the plurality of color channels of the pixel.

  • Patent number: 10958884
    Abstract: A variable-resolution screen apparatus and methodology for transforming an image from a microdisplay, display or projector into a variable-resolution image is described herein. The apparatus and methodology could take a high resolution part and a low resolution part, which could be created as a continuous stream of images that are masked to split into two, or as two interleaved images separated by time (or both). The two image streams are reassembled, the high resolution portion into the low resolution background, using various optical embodiments. The various embodiments use beam splitters, beam combiners, shutters, optical masks, lenses, mirrors, optical slabs, lens arrays and other optics in various combinations to create the variable-resolution image. The image from the microdisplay, display or projector is split (in some embodiments), transformed, and recombined to display on a screen or viewer's retina. This apparatus could be implemented in a virtual reality headset.

  • Patent number: 10866458
    Abstract: An electronic device may include display layers such as liquid crystal display layers and a backlight unit that provides illumination for the display layers. The backlight unit may include light-emitting diodes that emit light into the edge of a light guide film. To minimize the inactive area of the display, the light-emitting diodes may be tightly spaced to approximate a line light source instead of point light sources. Color and/or luminance compensation layers may be incorporated at various locations within the backlight structures to ensure that the backlight provided to the display layers is homogenous. A thin-film transistor layer of the display may be coupled to a printed circuit board by a flexible printed circuit. The flexible printed circuit may have additional solder mask layers to improve robustness, may include encapsulation, and may have traces with a varying pitch.
