krominansi

Krominansi is a term related to the perception and representation of color, specifically the color information within an image or video signal. It is distinct from luminance, which refers to the brightness or intensity of the light. In digital imaging and video compression, the chrominance component carries the color information, while the luminance component carries the brightness information. This separation is a fundamental principle in many color spaces, such as YCbCr, and is exploited in compression techniques because the human eye is generally more sensitive to changes in brightness than to changes in color. Therefore, chrominance information can often be sampled at a lower resolution than luminance without a significant perceived loss of image quality, leading to more efficient data storage and transmission. The term itself is derived from "chroma," meaning color, and "nansi," relating to a quality or state. Understanding chrominance is crucial in fields like digital television broadcasting, image processing, and computer graphics.
