OSA-UCS to REC.2100-HLG Converter - Color Space Converter

OSA-UCS color space introduction

Also known as the OSA-UCS color space.There are 3 channels in total, L,range from -10 to 8.j,range from -6 to 12.g,range from -10 to 6.
The OSA-UCS color space was developed by the Optical Society of America in the 1970s with the goal of creating a color space that provided a more uniform appearance than the CIE 1931 XYZ color space.
The OSA-UCS color space, also known as the Optical Society of America Uniform Color Scale.
Colors in the OSA-UCS color space are represented by three parameters: lightness (L), hue (J), and chroma (g).
OSA-UCS is used in the field of visual sciences for the research and precise measurement of color differences due to its uniformity.
The application of the OSA-UCS color space is relatively limited in the commercial sector, primarily because it is more complex to calculate and not as widely used as the CIELAB color space.

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.
