YCbCr - Wikipedia
WEBY′CbCr is used to separate out a luma signal (Y′) that can be stored with high resolution or transmitted at high bandwidth, and two chroma components (C B and C R) that can be bandwidth-reduced, subsampled, compressed, or otherwise treated separately for improved system efficiency.
Chroma subsampling - Wikipedia
WEBChroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance.
Chroma Subsampling: 4:4:4 vs 4:2:2 vs 4:2:0 - RTINGS.com
WEBMar 4, 2019 · Chroma subsampling is a type of compression that reduces the color information in a signal in favor of luminance data. This reduces bandwidth without significantly affecting picture quality. A video signal is split into two different aspects: luminance information and color information.
RGB vs YCbCr: Understanding Color Encoding in Digital Media
WEBOct 3, 2024 · YCbCr color space often uses subsampling (such as 4:2:2 or 4:2:0), which reduces the color resolution to achieve more efficient compression. This efficiency is a double-edged sword, as it can lead to a loss of image quality particularly in …
Video Beginner Series 10: YCbCr Chroma subsampling/resampling
WEBNov 8, 2021 · Common YCbCr color format using Chroma subsampling are YCbCR422 and YCbCr420. Note that YCbCr without Chroma subsampling can be called YCbCr444. Chroma resampling is the practice of re-creating the missing Chroma information.
Breaking down the format of the "Y Cb Cr Sub Sampling" EXIF tag
WEBSep 12, 2023 · When using exiftool to inspect various images, I've seen lots of different values for the Y Cb Cr Sub Sampling tag. A few examples: YCbCr4:4:4 (1 1) YCbCr4:2:0 (2 2)
Chroma Subsampling Techniques - RED Digital Cinema
WEBThe luma and chroma components would then be referred to as YUV (with analog) or YCbCr (with digital) as opposed to RGB. Once separated, the chroma resolution would then be reduced by half or more through a process called "chroma subsampling."
Chroma Subsampling: What Is It and Why Does It Matter? - MUO
WEBSep 26, 2022 · The YCbCr color space supports several chroma subsampling schemes expressed as an A:B:C ratio. A is the horizontal width of the sampled region in pixels, B denotes the number of chrominance samples (Cr, Cb) in the first row, and C denotes vertical sampling.
Ycbcr - Vocab, Definition, and Must Know Facts | Fiveable
WEBChroma Subsampling: Chroma subsampling is a method used in video compression where the resolution of the chrominance information is reduced relative to the luminance information, exploiting human perception characteristics.
Ycbcr color space - Vocab, Definition, and Must Know Facts
WEBYcbcr color space is a color model used primarily in video compression and image processing, separating the brightness (luminance) information from the color (chrominance) information.
