Chrominance refers to the color information in a video signal. It works alongside luminance, which represents brightness. Together, they create a complete color image.
For example, in surveillance systems, chrominance helps distinguish between similar objects by showing differences in color. This improves identification and overall image clarity.
Most video formats separate chrominance and luminance to reduce bandwidth and improve compression. While some loss of color detail may occur, the final image still appears accurate to the human eye.
By understanding chrominance, users can better evaluate video quality and choose equipment that meets their surveillance needs.
