YCgCo to xvYCC Converter - Color Space Converter

Also known as the YCgCo color space.There are 3 channels in total, Y,range from 0 to 1.Cg,range from -0.5 to 0.5.Co,range from -0.5 to 0.5.

Origin: The YCgCo color space was designed for digital video processing to provide a simple and reversible color transformation method, serving as an approximation of the YCbCr color space.

Primary Names: YCgCo color space, where 'Y' represents the luminance component, 'Cg' stands for the green difference component, and 'Co' represents the red-blue difference component.

Typically expressed as a triplet, for example: YCgCo(0.5, -0.25, 0.25) represents a color with specific luminance and chromatic differences.

Usage Scope: Mainly used in image coding and digital video processing, for example, it is applied in encoding standards such as JPEG XR and H.264/MPEG-4 AVC.

Additionally, due to the simple conversion process of YCgCo, it supports efficient hardware implementation and can be losslessly transformed back to the RGB format.

Also known as the xvYCC color space.There are 3 channels in total,Y,range from 0 to 255.Cb,range from 0 to 255.Cr,range from 0 to 255.

xvYCC was developed by Sony and standardized by the International Electrotechnical Commission (IEC) in 2005. It is an expansion over the standard YCbCr color space, designed to support a wider range of colors for high-definition video.

The main name is xvYCC, also known as IEC 61966-2-4 or extended-gamut YCC.

Similar to YCbCr, xvYCC is typically expressed as three component values (Y, Cb, Cr). However, xvYCC uses a signaling method that enables it to represent a broader range of colors. This includes values for Cb and Cr that, unlike YCbCr, can exceed the nominal range of video levels, going below 16 or above 235 in 8-bit terms.

xvYCC is used primarily in high-definition video formats and devices such as Blu-ray players, digital cameras, and HDTVs that support HDMI 1.3 or higher. It allows for more vivid and accurate color representation on capable devices.

xvYCC can display a wider range of color values than sRGB by allowing values that fall outside the typical RGB gamut. It achieves this by using the same color encoding method as YCbCr but permits values in the signaling that exceed the range of the BT.601 or BT.709 color spaces.
