YCgCo to REC.2100-PQ Converter - Color Space Converter

YCgCo color space introduction

Also known as the YCgCo color space.There are 3 channels in total, Y,range from 0 to 1.Cg,range from -0.5 to 0.5.Co,range from -0.5 to 0.5.
Origin: The YCgCo color space was designed for digital video processing to provide a simple and reversible color transformation method, serving as an approximation of the YCbCr color space.
Primary Names: YCgCo color space, where 'Y' represents the luminance component, 'Cg' stands for the green difference component, and 'Co' represents the red-blue difference component.
Typically expressed as a triplet, for example: YCgCo(0.5, -0.25, 0.25) represents a color with specific luminance and chromatic differences.
Usage Scope: Mainly used in image coding and digital video processing, for example, it is applied in encoding standards such as JPEG XR and H.264/MPEG-4 AVC.
Additionally, due to the simple conversion process of YCgCo, it supports efficient hardware implementation and can be losslessly transformed back to the RGB format.

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.
