  • Publication number: 20220264190
    Abstract: Apparatus and methods for providing solutions to the problem of preserving original creative intent for video playback on a target display are presented herein. According to one aspect, a video bitstream includes metadata with a flag indicative of creative intent for a target display. This metadata may include numerous fields that denote characteristics such as content type, content sub-type, intended white point, whether or not to use the video in Reference Mode, intended sharpness, intended noise reduction, intended MPEG noise reduction, intended Frame Rate Conversion, intended Average Picture Level, and intended color. This metadata is designed to make it effortless for the content creators to tag their content. The metadata can be added to the video content at multiple points, the status of the flag is set to TRUE or FALSE to indicate whether the metadata was added by the content creator or a third party.

  • Patent number: 11301972
    Abstract: A method for adjusting color saturation can determine a saturation adjustment from metadata that specifies an adjustment of color saturation based on a first display and from precomputed data, such as data in one or more look-up tables, that specifies a relationship between image data in a first color space and image data in a second color space. An input image in the first color space is converted into an image in the second color space, and the color saturation is adjusted while the image data is in the second color space, which can be a geometrically non-symmetrical color space.

  • Patent number: 11277543
    Abstract: In a method for dithering image data, a processor receives an input image in a first color space and a first bit depth larger than 8 bits. The processor converts the input image into a first image in a perceptually uniform color space, such as the BT. 2100 ICtCp color space, with pixel values scaled to be within a target bit depth, it quantizes the first image to generate a quantized image, it generates an error image between the first image and the quantized image, and using a random threshold, it generates a dithered image based on the random threshold, the error image, and the quantized image, allowing to reduce the bit-depth representation for visually consistent reproduction by two bits.

  • Patent number: 11186476
    Abstract: In one embodiment, a dual modulator display systems and methods for rendering target image data upon the dual modulator display system are disclosed where the display system receives target image data, possible HDR image data and first calculates display control signals and then calculates backlight control signals from the display control signals. This order of calculating display signals and then backlight control signals later as a function of the display systems may tend to reduce clipping artifacts. In other embodiments, it is possible to split the input target HDR image data into a base layer and a detail layer, wherein the base layer is the low spatial resolution image data that may be utilized as for backlight illumination data. The detail layer is higher spatial resolution image data that may be utilized for display control data.

  • Patent number: 11183143
    Abstract: A processor receives input video data of a video dynamic range and input dynamic metadata. It also receives: input graphics data of a graphics dynamic range and input static metadata, display identification data from a target display over a video interface, and a blending priority map characterizing a per-pixel priority of output pixels in an image generated by blending the input video data and the input graphics data. A video mapping function and a graphics mapping function which map data from the input video and graphics dynamic ranges to the target dynamic range are generated based on the dynamic and static metadata. Then, the input and graphics data are blended based on the blending priority map and a per-pixel decision to map pixels to the target dynamic range using either the video mapping function or the graphics mapping function.

  • Publication number: 20210349384
    Abstract: An angular image of a scene may be displayed using a light field display. The light field display may comprise a plurality of projection units. Each of the projections units may comprise an imaging system and an optical system. The imaging system may illuminate pixels of a planar image of the scene. Light corresponding to each of the pixels may be directed towards the optical system. The optical system may comprise first and second lenses for redirecting each light beam corresponding to a pixel in different directions. In some embodiments the first and second lenses form a globe lens. A diffusion system may conceal the optical systems. Additionally, or alternatively, the diffusion system may produce a uniform distribution of light at a plurality of different viewing angles.

  • Patent number: 11158032
    Abstract: Input scene images are captured from an original scene. The input scene images may be represented in an input color space. The input scene images are converted into color-space-converted scene images in one of an LMS color space, an ICtCp color space, etc. Scene light levels represented in the color-space-converted scene images are mapped, based at least in part on an optical transfer function, to mapped light levels. A tone mapping is applied to the mapped light levels to generate corresponding display light levels to be represented in display images. The display images may be rendered on a target display.
