Samsung's New 50-Megapixel Camera Sensor Supports Staggered HDR

Samsung today announced a new camera sensor featuring a number of new technologies that will offer improved HDR, low-light performance, and auto-focusing. The ISOCELL GN2 is a 50 megapixel sensor with 1.4-micrometer (μm)-sized pixels. The GN2 supports staggered HDR, which lets a device capture short and long exposures simultaneously, for HDR images with fewer motion artifacts. Staggered HDR can also enable computational HDR for video. Support for staggered HDR sensors is a key feature of Qualcomm's latest flagship chip for phones, the Snapdragon 888. Samsung also claims that staggered HDR is 24% more power-efficient compared to the traditional HDR technique. The GN2 also sports Dual Pixel Pro, an improved auto-focus (AF) system that uses all sensor pixels for focusing. While previous dual-pixel AF systems can only detect pattern changes horizontally, Dual Pixel Pro splits pixel elements diagonally, so it can also use vertical information to lock focus quickly. The GN2 also has Smart ISO Pro, which does for ISO what staggered HDR does for exposure length. The technology "takes readouts from both high and low ISO to instantly create high dynamic range images with less motion-artifacts." It can also take and process multiple high-ISO frames quickly, for an effective maximum ISO of "close to one-million". For video, the GN2 supports full-HD videos at 480 frames-per-second (fps) or 4K at 120fps. The ISOCELL GN2 is already in mass production, meaning it should make its way into phones soon.
