XYZ(ciexyz,cie1931,XYZ D65) to YIQ Converter - Color Space Converter

XYZ(ciexyz,cie1931,XYZ D65) color space introduction

Also known as the XYZ(ciexyz,cie1931,XYZ D65) color space.There are 3 channels in total, X,range from 0 to 95.045592705167.Y,range from 0 to 100.Z,range from 0 to 108.9057750759878.
Origin: The XYZ color space was defined in 1931 by the International Commission on Illumination (CIE) based on the visual experiments conducted on a large number of observers.
Main Name: CIE 1931 XYZ color space, comprising the X, Y, Z color channels.
Usage: The XYZ color space is primarily used for color measurement, color science, and color conversions. It provides a neutral, device-independent reference for other color spaces, often serving as an intermediate color space for conversions.
Additionally, it's worth noting that the XYZ color space is frequently used as an intermediate step for converting from one device-dependent color space (like sRGB or Adobe RGB) to another. It is closely related to the Lab color space, where XYZ can be converted to Lab, offering a more uniform space for color comparisons and difference measurements.

YIQ color space introduction

Also known as the YIQ color space.There are 3 channels in total,Y,range from 0 to 1.I,range from -0.5957 to 0.5957.Q,range from -0.5226 to 0.5226.
Origin: The YIQ color space was specifically designed for the North American NTSC color television standard to accommodate compatibility between color and monochrome television broadcasts.
Primary Names: YIQ color space, where 'Y' represents the luminance component, 'I' represents the in-phase component, and 'Q' represents the quadrature component.
Typically expressed as a triplet, for example: YIQ(0.5, 0.2, 0.3) represents a color with specific luminance and chromaticity.
Usage Scope: Mainly used in the North American NTSC (National Television System Committee) color television broadcasting system. Although less used in modern digital technology, it played a significant role during the era of analog television.
Additionally, the YIQ color space allows old black and white television receivers to receive and correctly display the luminance signal from color broadcasts without interference from the color information.
