LAB(cielab) to REC.2100-HLG 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.

REC.2100-HLG color space introduction

Also known as the REC.2100-HLG color space.There are 3 channels in total,Red,range from 0 to 1.Green,range from 0 to 1.Blue,range from 0 to 1.
Rec. 2100 HLG (Hybrid Log-Gamma) is an HDR standard developed by the BBC and NHK, designed for broadcast television. It supports a wide range of brightness levels for more realistic and dynamic imaging.
Rec. 2100 HLG color space.
In the Rec. 2100 HLG color space, colors are represented through Red (R), Green (G), and Blue (B) channels, adapting to different brightness levels of HDR displays.
Rec. 2100 HLG is primarily used in broadcast television supporting HDR, and it is backward compatible with standard dynamic range (SDR) displays.
The backward compatibility of Rec. 2100 HLG allows the same content to be displayed on both HDR and SDR displays without needing different versions.
