The HDR (High Dynamic Range or high dynamic range) image processing in smartphone cameras responds to a "fundamental physical limitation of small-sized CMOS sensors." That is, they are sensors unable to simultaneously capture the ends of light and shadow in a highly contrasting scene. To solve this problem, the operating system uses a real-time algorithm.
