The S5KGH1 from Samsung is a 43.7-megapixel CMOS image sensor built with the first 0.7-micrometer (μm)-pixel. This image sensor embraces 43.7-million 0.7μm-sized pixels in a super-small package, providing the optimum solution for slim full-display devices. In low-light environments, the sensor makes use of pixel-merging Tetracell technology that enables higher light sensitivity equivalent to that of a 1.4μm-pixel image sensor. It also supports a gyro-based electronic image stabilization (EIS) and a high-performing phase detection auto-focus technology, Super PD, allowing fast and accurate autofocus. In addition, the real-time high dynamic range (HDR) feature delivers more balanced exposure and richer color even in mixed-light environments.
