LAB(cielab) to YCbCr(YCC) Converter - Color Space Converter

LAB(cielab) color space introduction

Also known as the LAB(cielab) color space.There are 3 channels in total, lightness,range from 0 to 100.a,range from -100 to 100.b,range from -100 to 100.
Defined by the International Commission on Illumination (CIE) in 1976, as an improvement and extension of the CIE XYZ color space, designed to be a closer approximation to human visual non-linearity.
Commonly known as CIELAB color space, abbreviated as L*a*b* or Lab.
Lab colors are typically represented by three coordinates: L* for lightness, a* for green to red chromaticity, and b* for blue to yellow chromaticity. They can be algorithmically converted to other color spaces for display or printing on different devices.
The Lab color space is extensively used in color measurement and management, particularly important in fields requiring precise color matching and assessment such as digital printing, photography, image analysis, and industrial color testing.
The advantage of the Lab color space lies in its device independence, allowing for consistent and accurate color conversion across different devices and software.

YCbCr(YCC) color space introduction

Also known as the YCbCr(YCC) color space.There are 3 channels in total,Y,range from 16 to 235.Cb,range from 16 to 240.Cr,range from 16 to 240.
The YCbCr color space was specifically designed for digital television and video compression standards like MPEG and JPEG, aiming to minimize data size while maintaining high-quality imagery during the compression process.
The primary name is YCbCr. It is often confused with YUV, although they are technically different.
The YCbCr color space is typically used in a digital format, expressed as a combination of three component values, like (Y, Cb, Cr). For 8-bit video signals, these components typically range from 16 to 235 for Y, and 16 to 240 for Cb and Cr.
YCbCr is predominantly used in digital video capture, processing, storage, and transmission. It forms the core color space for television broadcasting, DVD videos, and image compression standards such as JPEG.
In the YCbCr color space, Y represents the luminance component, while Cb and Cr represent the chrominance components of blue and red, separated from the Y component, allowing chroma subsampling to reduce data amount. As the human eye is more sensitive to luminance than to chrominance, this separation usually doesn't affect the viewing experience.
