The 200MP sensor called Samsung Isocell HP3 comes with the industry’s smallest individual pixels, which usually will not be something to brag about, but cramming 200 million pixels on a smartphone-sized sensor does include some never-before seen engineering, and the end result promises to bring a small revolution.
Of course, those of you interested in photography will know that there are all sorts of issues as individual pixels get smaller, or basically microscopic in the case of such a high-res sensor. A super tiny pixel gets less light and this results in poor low-light performance, but worry not as there is an industry solution for this which is to bundle multiple pixels into one.
So the HP3 sensor can bundle 4 pixels into 1 and give you 50MP images, or even 4 blocks of 4 pixels, or a total of 16 pixels into one kind of “superpixel”, and that will produce 12.5MP photos. In the case of the new HP3 sensor, we also have Super QPD technology, which means every single pixel has auto-focus capabilities, plus there is one lens over every block of 4 pixels, which work together to ensure faster auto focusing.
