LAB(cielab) to YcCbcCrc Converter - Color Space Converter

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.

Also known as the YcCbcCrc color space.There are 3 channels in total,Yc,range from 0 to 1.Cbc,range from -0.5 to 0.5.Crc,range from -0.5 to 0.5.

The YcCbcCrc color space is based on the traditional YCbCr color space, optimized for chrominance components of High Definition Television (HDTV) signals to accommodate video signals of different resolutions during transmission and processing.

YcCbcCrc uses a component representation method similar to YCbCr, usually including a luminance component Yc and two chrominance components Cbc and Crc. The difference lies in the scaling factors for Cbc and Crc, which are adjusted according to different HDTV standards. In 8-bit video signals, the range of values for Yc, Cbc, and Crc may vary depending on the standard.

This color space is primarily used in professional video production and editing, excelling in video compression and broadcast transmission, especially when dealing with high-definition video signals.

YcCbcCrc adapts to higher resolution video signals with different scaling and offset compared to standard YCbCr. This can improve the representation of chrominance signals, particularly during color conversion and color grading processes.
