YIQ to lms Converter - Color Space Converter

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.

lms color space introduction

Also known as the lms color space.There are 3 channels in total,long,range from 0 to 100.medium,range from 0 to 100.short,range from 0 to 100.
The LMS color space is based on the response of the human eye's cone cells to color, consisting of the responses from three different types of cone cells which are most responsive to long, medium, and short wavelengths of light respectively.
LMS stands for Long, Medium, and Short wavelengths.
The LMS color space typically uses three coordinates to express colors, corresponding directly to the responses of the cone cells. This space is often used to calculate transformations to other color spaces that are perceptually closer to human vision, such as from RGB.
The LMS color space is primarily used in the fields of biology and vision science, particularly for simulating and understanding human visual perception.
Since LMS is based on physiological characteristics, it is not commonly used for practical applications such as image processing or color printing but serves as a research and theoretical model.
