  2. YCbCr - Wikipedia

    en.wikipedia.org/wiki/YCbCr

    YCbCr, Y′CbCr, or Y Pb/Cb Pr/Cr, also written as YC B C R or Y′C B C R, is a family of color spaces used as a part of the color image pipeline in digital video and photography systems. Y′ is the luma component and C B and C R are the blue-difference and red-difference chroma components.

  3. YCoCg - Wikipedia

    en.wikipedia.org/wiki/YCoCg

    The three values of the YCoCg color model are calculated as follows from the three color values of the RGB color model: [2] [] = [] [] The values of Y are in the range from 0 to 1, while Co and Cg are in the range of −0.5 to 0.5, as is typical with "YCC" color models such as YCbCr.

  4. Chrominance - Wikipedia

    en.wikipedia.org/wiki/Chrominance

    For example, when an ordinary RGB digital image is compressed via the JPEG standard, the RGB color space is first converted (by a rotation matrix) to a YCbCr color space, because the three components in that space have less correlation redundancy and because the chrominance components can then be subsampled by a factor of 2 or 4 to further ...

    I was going to create a program in VB6 that uses the Commodore64 color palette, but I need to convert your YPbPr numbers (in the range of -1 to +1) to RGB numbers (in the range of 0 to 255). I do not know any proper conversion formula for YPbPr to RGB, and there none on the internet that I can find with a Google search.

  6. Talk:YCbCr - Wikipedia

    en.wikipedia.org/wiki/Talk:YCbCr

    If we consider how YCbCr relates to RGB, it's worth noting that there is no article titled "RGB" on Wikipedia, only an article on RGB color spaces.That article makes it clear that there isn't one single RGB color space, but rather multiple color spaces built on the RGB color model, each one with its own primaries, transfer functions, white points, etc.

  7. YIQ - Wikipedia

    en.wikipedia.org/wiki/YIQ

    YIQ is the color space used by the analog NTSC color TV system. I stands for in-phase, while Q stands for quadrature, referring to the components used in quadrature amplitude modulation. Other TV systems used different color spaces, such as YUV for PAL or YDbDr for SECAM. Later digital standards use the YCbCr color space.

  8. RGB color spaces - Wikipedia

    en.wikipedia.org/wiki/RGB_color_spaces

    RGB color spaces is a category of additive colorimetric color spaces [1] specifying part of its absolute color space definition using the RGB color model. [ 2 ] RGB color spaces are commonly found describing the mapping of the RGB color model to human perceivable color, but some RGB color spaces use imaginary (non-real-world) primaries and thus ...

  9. Comparison of color models in computer graphics - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_color_models...

    No one color model is necessarily "better" than another. Typically, the choice of a color model is dictated by external factors, such as a graphics tool or the need to specify colors according to the CSS2 or CSS3 standard. The following discussion only describes how the models function, centered on the concepts of hue, shade, tint, and tone.
