LABh(hunter-lab,hlab) to xvYCC Converter - Color Space Converter

Also known as the LABh(hunter-lab,hlab) color space.There are 3 channels in total, lightness,range from 0 to 100.a,range from -128 to 128.b,range from -128 to 128.

Developed by Richard S. Hunter in the 1940s as a color scale based on opponent-color theory. It is an adaptation of the CIE XYZ color space to be more perceptually linear.

Often referred to as Hunter Lab, or Lab Hunter.

Colors in the Hunter Lab color space are expressed through three coordinates: L (for lightness), a (red/green value), and b (blue/yellow value). These are calculated from CIE XYZ using Hunter's specific equations.

Hunter Lab is used in various industries for color matching, quality control, and other applications where a perceptually linear space is beneficial for color difference measurement.

Although similar to CIELAB, the Hunter Lab color space is used less frequently in contemporary applications. However, it remains significant in industries that adopted it early on and continue to rely on its specific color-rendering properties.

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.
