: Modern cameras and smartphones are designed to process 4:2:0 data quickly, allowing for rapid burst shooting and smooth video recording. Limitations and Trade-offs
: Platforms like YouTube and Netflix use 4:2:0 to minimize the bandwidth required for high-definition playback. 4-2.jpg
Chroma subsampling is a technique that reduces the resolution of color information (chroma) while maintaining the full resolution of brightness information (luma). The 4:2:0 scheme is highly efficient because it records only a quarter of the original color data. This is achieved by sampling color for every 2x2 block of pixels rather than for every individual pixel. The Biological Basis : Modern cameras and smartphones are designed to
