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

REC.2100-PQ color space introduction

Also known as the REC.2100-PQ 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 PQ (Perceptual Quantizer) is one of the HDR standards developed under ITU-R BT.2100, designed to accurately represent a wide range of brightness levels from deep blacks to intense highlights, far exceeding what standard dynamic range (SDR) can offer.
Rec. 2100 PQ color space.
In the Rec. 2100 PQ color space, colors are represented through Red (R), Green (G), and Blue (B) channels, designed based on the human visual system to ensure that each increment in brightness is perceived uniformly.
Rec. 2100 PQ is primarily used in HDR video production and playback that require a wide range of brightness representation.
Rec. 2100 PQ is widely used in professional video production and high-end television playback due to its precision in representing HDR content and uniform perceptual brightness increments.

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.
