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

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.

Also known as the HSI color space.There are 3 channels in total,hue,range from 0 to 360.saturation,range from 0 to 100.intensity,range from 0 to 255.

Origin: The HSI color space was designed to better match the color perception characteristics of the human eye, suitable for processing color-related information.

Primary Names: HSI, which includes H (Hue), S (Saturation), and I (Intensity) as the three color channels.

Typically expressed as a triplet, for example: hsi(120°, 0.5, 0.75) represents a green hue with medium saturation and high brightness.

Usage Scope: Extensively used in image processing and analysis, such as color segmentation, edge detection, target tracking, etc.

Additionally, HSI can be converted to and from RGB, and while similar to HSV and HSL, in HSI, I (Intensity) represents the overall brightness of the color.
