How do camera systems work?

Multi-camera systems work similarly to the human eye, but with more "eyes" added. Phones have different sensors like 48MP and 12MP because each has a different role. The 48MP sensor is usually used for capturing high resolution and detail, while the 12MP sensor is preferred for wide-angle shots or better performance in night mode. Just like a photographer changes lenses, the phone quickly selects between these cameras to create a single photo. In night mode, auxiliary sensors often kick in alongside the wide-angle and main sensors to improve low-light performance. Some phones also have 2x or 5x zoom lenses, making digital zoom more efficient than optical zoom. Some models even include depth sensors or thermal sensors to add extra layers—like layers of a cake. This way, a single photo achieves both sharpness and balanced lighting.
