YCbCr(YCC) to OSA-UCS Converter - Color Space Converter

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.

OSA-UCS color space introduction

Also known as the OSA-UCS color space.There are 3 channels in total,L,range from -10 to 8.j,range from -6 to 12.g,range from -10 to 6.
The OSA-UCS color space was developed by the Optical Society of America in the 1970s with the goal of creating a color space that provided a more uniform appearance than the CIE 1931 XYZ color space.
The OSA-UCS color space, also known as the Optical Society of America Uniform Color Scale.
Colors in the OSA-UCS color space are represented by three parameters: lightness (L), hue (J), and chroma (g).
OSA-UCS is used in the field of visual sciences for the research and precise measurement of color differences due to its uniformity.
The application of the OSA-UCS color space is relatively limited in the commercial sector, primarily because it is more complex to calculate and not as widely used as the CIELAB color space.
