High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual. The term is often used in discussing the dynamic ranges of images , videos , audio or radio .
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.
HDR: High dynamic range. Techniques that allow a digital image to show a wider contrast range than current image sensors can record in one file. Some cameras have firmware to do the processing. [10] ICM: Intentional camera movement. The camera or the focus or zoom of its lens is adjusted by the photographer during an exposure in order to ...
The earliest known smartphone to feature high dynamic range filming is the Sony Xperia Z, 2013, where frames are arrayed by changing the exposure every two lines of pixels to create a spatially varying exposure (SVE). [12] [13] As of 2019, high-end camera phones can produce video with up to 4K resolution at 60 frames per second for smoothness. [14]
Perceptual quantizer: PQ is a transfer function developed by Dolby for HDR and allowing a luminance level of up to 10,000 cd/m 2. It is standardized in Rec. 2100 [10] and also as SMPTE ST 2084. [11] Hybrid log–gamma: HLG is a transfer function developed by NHK and BBC for HDR and offering some backward compatibility on SDR displays.
Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.
