Samsung has announced a new 50MP camera sensor called the ISOCELL GN1. It is a 1/1.3 camera sensor with 50MP resolution and has larger pixels. The size of the sensor is actually slightly bigger than the 108MP ISOCELL HM1 used in the Galaxy S20 Ultra.
It is the first sensor to feature both dual-pixel autofocus and Tetracell (4-in-1) pixel binning. Dual-pixel autofocus technology was first used in Galaxy S7 by Samsung. This means the image sensor uses 100% of pixels in the sensor for autofocus.
Samsung says that the ISOCELL GN1’s native pixel size of 1.2μm can be turned into 2.4μm pixels using Tetracell technology. According to Samsung, the new sensor uses Tetracell technology by binning 4 pixels in 1 and hence outputting 12.5MP still images with 2.4μm pixels for improved low-light photography.
Samsung also says the 50MP sensor can capture pictures that are comparable to its 100MP cameras.
The 50MP ISOCELL GN1 camera sensor comes with a faster autofocus mechanism that focuses on an object quickly even in the extreme low-light environment to deliver both brighter and sharper results.
The camera sensor supports 8K 30fps video recording. It can also record 1080p videos 240fps (with autofocus) and 400fps (without autofocus). It includes Smart ISO, gyro-based EIS.
Samsung has made it clear that its new 50MP ISOCELL GN1 camera sensor has already gone into mass production this month. It is unknown when we will see the new phones utilizing the new camera sensor. Meanwhile, there are speculations on Samsung to be working on 150MP and even higher 250MP and 600MP camera sensors as well.
