  2. Y′UV - Wikipedia

    en.wikipedia.org/wiki/Y′UV

    A color is described as a Y′ component and two chroma components U and V. The prime symbol (') denotes that the luma is calculated from gamma-corrected RGB input and that it is different from true luminance. [1] Today, the term YUV is commonly used in the computer industry to describe colorspaces that are encoded using YCbCr. [2]

  3. Chroma subsampling - Wikipedia

    en.wikipedia.org/wiki/Chroma_subsampling

    Pixel formats used in Y'CbCr can be referred to as YUV too, for example yuv420p, yuvj420p and many others. In a similar vein, the term luminance and the symbol Y are often used erroneously to refer to luma, which is denoted with the symbol Y'. The luma (Y') of video engineering deviates from the luminance (Y) of color science (as defined by CIE).

  4. YCbCr - Wikipedia

    en.wikipedia.org/wiki/YCbCr

    YCbCr is sometimes abbreviated to YCC.Typically the terms Y′CbCr, YCbCr, YPbPr and YUV are used interchangeably, leading to some confusion. The main difference is that YPbPr is used with analog images and YCbCr with digital images, leading to different scaling values for U max and V max (in YCbCr both are ) when converting to/from YUV.

  5. Photoswitch - Wikipedia

    en.wikipedia.org/wiki/Photoswitch

    Spiropyran and Merocyanine undergo ring opening/closing mechanisms upon photo irradiation. Diarylethene and donor-acceptor Stenhouse adducts exhibit changes in color upon photoisomerization. Stilbene is a model photoswitch for studying photochemistry. A photochromic compound can change its configuration or structure upon irradiation with light.

  6. ChromaFlair - Wikipedia

    en.wikipedia.org/wiki/ChromaFlair

    The color observed is created entirely by the refractive properties of the flakes, analogous to the perception of rainbow colors in oil slicks. ChromaFlair paint has also been used as a substitute for optically variable ink in the use of counterfeiting the currency of the United States.
