LABh(hunter-lab,hlab) to YDbDr 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 YDbDr color space.There are 3 channels in total,Y,range from 0 to 1.Db,range from -1.333 to 1.333.Dr,range from -1.333 to 1.333.

Origin: The YDbDr color space was designed for the European SECAM color television system for color encoding in analog television broadcasting.

Primary Names: YDbDr color space, where 'Y' represents the luminance component, 'Db' and 'Dr' respectively represent the blue and red difference components.

Typically expressed as a triplet, for example: YDbDr(0.5, -0.1, 0.9) represents a color with specific luminance and chromaticity differences.

Usage Scope: Primarily used in SECAM standard color television broadcasting, which is a color video standard specific to certain countries and regions.

Additionally, compared to PAL and NTSC, SECAM uses frequency division multiplexing to separate the chrominance components, reducing cross-color interference during color image transmission.
