LAB(cielab) to YDbDr Converter - Color Space Converter

LAB(cielab) color space introduction

Also known as the LAB(cielab) color space.There are 3 channels in total, lightness,range from 0 to 100.a,range from -100 to 100.b,range from -100 to 100.
Defined by the International Commission on Illumination (CIE) in 1976, as an improvement and extension of the CIE XYZ color space, designed to be a closer approximation to human visual non-linearity.
Commonly known as CIELAB color space, abbreviated as L*a*b* or Lab.
Lab colors are typically represented by three coordinates: L* for lightness, a* for green to red chromaticity, and b* for blue to yellow chromaticity. They can be algorithmically converted to other color spaces for display or printing on different devices.
The Lab color space is extensively used in color measurement and management, particularly important in fields requiring precise color matching and assessment such as digital printing, photography, image analysis, and industrial color testing.
The advantage of the Lab color space lies in its device independence, allowing for consistent and accurate color conversion across different devices and software.

YDbDr color space introduction

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.
