Modern cameras combine optics with rapid multi-frame capture, scene understanding, and selective processing to produce a polished image before you open the gallery.
A camera pipeline can identify faces, skies, plants, buildings, and other regions before applying adjustments. This lets the phone tune exposure, color, texture, and noise reduction locally instead of treating the entire frame in the same way.
