UVW(cieuvw,cie1964) to xvYCC Converter - Color Space Converter

Also known as the UVW(cieuvw,cie1964) color space.There are 3 channels in total, U,range from -134 to 224.V,range from -140 to 122.W,range from 0 to 100.

Developed by the CIE in 1964 as an improvement over the CIE 1960 UCS for better perceptual uniformity across different hues and lightness levels.

It is known as the CIE 1964 (U^*, V^*, W^*) color space, and commonly abbreviated as CIE UVW.

The color in the CIE UVW space is represented by three coordinates: (U^*), (V^*), and (W^*). These are calculated from the XYZ coordinates with a series of transformations intended to achieve a more uniform color space, taking into account the luminance factor.

The CIE UVW color space is used in specialized applications that require a uniform measure of color differences, such as in colorimetry research and the development of color standards.

The CIE UVW color space is less commonly used in practical applications today, having been largely replaced by more advanced color spaces like CIELAB and CIELUV, which offer better perceptual uniformity.

Also known as the xvYCC color space.There are 3 channels in total,Y,range from 0 to 255.Cb,range from 0 to 255.Cr,range from 0 to 255.

xvYCC was developed by Sony and standardized by the International Electrotechnical Commission (IEC) in 2005. It is an expansion over the standard YCbCr color space, designed to support a wider range of colors for high-definition video.

The main name is xvYCC, also known as IEC 61966-2-4 or extended-gamut YCC.

Similar to YCbCr, xvYCC is typically expressed as three component values (Y, Cb, Cr). However, xvYCC uses a signaling method that enables it to represent a broader range of colors. This includes values for Cb and Cr that, unlike YCbCr, can exceed the nominal range of video levels, going below 16 or above 235 in 8-bit terms.

xvYCC is used primarily in high-definition video formats and devices such as Blu-ray players, digital cameras, and HDTVs that support HDMI 1.3 or higher. It allows for more vivid and accurate color representation on capable devices.

xvYCC can display a wider range of color values than sRGB by allowing values that fall outside the typical RGB gamut. It achieves this by using the same color encoding method as YCbCr but permits values in the signaling that exceed the range of the BT.601 or BT.709 color spaces.
