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 ...
UHD Phase A is a set of guidelines from the Ultra HD Forum for the distribution of SDR and HDR content using Full HD 1080p and 4K UHD resolutions. It requires a color depth of 10 bits per sample, a color gamut of Rec. 709 or Rec. 2020, a frame rate of up to 60 fps, a display resolution of 1080p or 2160p and either standard dynamic range (SDR ...
Tone mapped high-dynamic-range (HDR) image of St. Kentigern's Church in Blackpool, Lancashire, England. In photography and videography, multi-exposure HDR capture is a technique that creates high dynamic range (HDR) images (or extended dynamic range images) by taking and combining multiple exposures of the same subject matter at different exposures.
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.
1080p (1920 × 1080 progressively displayed pixels; also known as Full HD or FHD, and BT.709) is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; [1] the p stands for progressive scan, i.e. non-interlaced.
Sony α7R II - Full Frame 42 Megapixel Sensor, but only 100 Mbit/s in H.264 and the APS-C crop mode is better for 4K than the full frame mode; Sony α7R III; Sony α7R IV; Sony α7R V; Sony α7S - 4K: 30p/24p, 4:2:2 8 bits. Does not support internal 4K recording, must use an external recorder via HDMI, but see Sony α7S II. Only 1080p is ...
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.
Combo-cameras combine full-feature still cameras and camcorders in a single unit. The Sanyo Xacti HD1 was the first such unit, combining the features of a 5.1 megapixel still camera with a 720p video recorder with improved handling and utility. Canon and Sony have introduced camcorders with still-photo performance approaching that of a digicam ...
