OSA-UCS to YDbDr Converter - Color Space Converter

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.

YDbDr color space introduction

Also known as the YDbDr color space.There are 3 channels in total,Y,range from 0 to 1.Db,range from -1.333 to 1.333.Dr,range from -1.333 to 1.333.
Origin: The YDbDr color space was designed for the European SECAM color television system for color encoding in analog television broadcasting.
Primary Names: YDbDr color space, where 'Y' represents the luminance component, 'Db' and 'Dr' respectively represent the blue and red difference components.
Typically expressed as a triplet, for example: YDbDr(0.5, -0.1, 0.9) represents a color with specific luminance and chromaticity differences.
Usage Scope: Primarily used in SECAM standard color television broadcasting, which is a color video standard specific to certain countries and regions.
Additionally, compared to PAL and NTSC, SECAM uses frequency division multiplexing to separate the chrominance components, reducing cross-color interference during color image transmission.
