    On January 4, 2016, the Ultra HD Alliance announced their certification requirements for an HDR display. [ 23 ] [ 24 ] The HDR display must have either a peak brightness of over 1000 cd/m 2 and a black level less than 0.05 cd/m 2 (a contrast ratio of at least 20,000:1) or a peak brightness of over 540 cd/m 2 and a black level less than 0.0005 ...

  3. High-dynamic-range rendering - Wikipedia

    en.wikipedia.org/wiki/High-dynamic-range_rendering

    Thus HDR rendering systems have to map the full dynamic range of what the eye would see in the rendered situation onto the capabilities of the device. This tone mapping is done relative to what the virtual scene camera sees, combined with several full screen effects , e.g. to simulate dust in the air which is lit by direct sunlight in a dark ...

    Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. [1] [2] [3] It covers content creation, distribution, and playback.[1] [4] [5] [6] It includes dynamic metadata that define the aspect ratio and adjust the picture based on a display's capabilities on a per-shot or even per-frame basis, optimizing the presentation.

  7. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    The term resolution is often considered equivalent to pixel count in digital imaging, though international standards in the digital camera field specify it should instead be called "Number of Total Pixels" in relation to image sensors, and as "Number of Recorded Pixels" for what is fully captured.
