UVW(cieuvw,cie1964) to REC.2100-PQ Converter - Color Space Converter

UVW(cieuvw,cie1964) color space introduction

Also known as the UVW(cieuvw,cie1964) color space.There are 3 channels in total, U,range from -134 to 224.V,range from -140 to 122.W,range from 0 to 100.
Developed by the CIE in 1964 as an improvement over the CIE 1960 UCS for better perceptual uniformity across different hues and lightness levels.
It is known as the CIE 1964 (U^*, V^*, W^*) color space, and commonly abbreviated as CIE UVW.
The color in the CIE UVW space is represented by three coordinates: (U^*), (V^*), and (W^*). These are calculated from the XYZ coordinates with a series of transformations intended to achieve a more uniform color space, taking into account the luminance factor.
The CIE UVW color space is used in specialized applications that require a uniform measure of color differences, such as in colorimetry research and the development of color standards.
The CIE UVW color space is less commonly used in practical applications today, having been largely replaced by more advanced color spaces like CIELAB and CIELUV, which offer better perceptual uniformity.

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.
