With the ISOCELL GN1 sensor, Samsung’s priority is a high resolution and fast autofocus.
Samsung today unveiled the new 50-megapixel sensor called ISOCELL GN1. It is Samsung’s first dual-pixel autofocus sensor and tetracell combination, offering higher performance and better image quality in low light.
The pixel size is 1.2μm, almost as much as a conventional camera sensor offers. The main competitor to this sensor is the Sony IMX689, which is found in phones like the Oppo Find X2 Pro and has a 48-megapixel 1.22μm size.
Normally the Samsung sensor will capture 12.5-megapixel photos with four pixels combined into a single one. The advent of the dual-pixel autofocus is valuable because Samsung has failed in this space.
The Galaxy S20 Ultra, which has a 108-megapixel sensor without dual-pixel technology, has suffered from autofocus performance. Samsung says it is testing a solution even though it has not yet implemented it.
