Samsung today has announced a brand-new flagship sensor in the form of the ISOCELL GN1. The new sensor is seemingly a follow-up to the 108MP ISOCELL HMX and HM1 sensors that we’ve seen employed by Xiaomi devices and the Galaxy S20 Ultra.
The big changes in the new GN1 is that it uses are different optical formula to the existing larger megapixel sensors. It’s only a bit less than half the resolution at a maximum of 50 megapixels, however the per-pixel pitch grows from 0.8µm to 1.2µm.
It seems that Samsung’s main rationale to grow to a larger pixel pitch wasn’t just the per-pixel increased light gathering ability, but rather the enablement to re-introduce full sensor dual-pixel phase-detection. The existing 108MP sensors that have been out...
