YCbCr (Color Space)
YCbCr is a color space used in digital video and image compression systems, representing color as one luma component (Y) and two chroma components (Cb and Cr). The Y component corresponds to luminance (brightness), while Cb and Cr represent the blue-difference and red-difference chroma information, respectively. By separating luminance from chrominance, YCbCr allows for more efficient compression techniques, as the human eye is more sensitive to changes in brightness than color, enabling reduced bandwidth without significant loss of image quality.
