Immediately two insiders from China reported that Samsung would soon introduce a mobile sensor with a resolution of 200 megapixels, and they will start using it next year – in the new flagship Galaxy S22.
Mobile camera manufacturers have two ways to increase the size of sensors – make pixels larger or increase their number. Samsung is taking the second path so far, as are many other Android smartphone makers. In both cases, the main goal is to get a larger sensor so that more light falls on it and the resulting image is of better quality.
According to rumors, Samsung’s 200MP camera will get 0.64μm pixels – slightly smaller than the 0.8μm pixels in the new 108MP camera from the Galaxy S21 Ultra. But due to the almost doubled resolution, the new camera sensor is physically larger by 15%.
The small pixel size can be compensated for by technology that allows you to combine 4 or 8 pixels into one. That is, you can get photos from 25 or 40 megapixels with great detail and sufficient illumination.
Modern smartphones can already cope with this resolution – the bandwidth of the Exynos 2100 chip in the Galaxy S21 is enough to process a picture from a 200-megapixel camera. Most likely, the new generation of processors will be able to process such images even faster.
