Samsung has unveiled the ISOCELL HP3, its latest 200-megapixel camera sensor. The sensor has the industry's smallest pixels at 0.56 microns, 20 percent smaller than the previous biggest. It has autofocus capability in every pixel, binning for better low light capability, and multi-gain ISO. Mass production is set to begin this year, and you'll probably see 200- megapixel phones using the sensor in 2023.
