This is the first sensor to have both Dual Pixel and Tetracell technology along with 1.2μm pixels. That means the sensor is designed to take 4-pixel burst mode into 1, producing 12.5MP images but actually has pixels with a whopping 2.4μm.
According to Yongin Park, the executive vice president of sensor business at Samsung, ISOCELL GN1 is another way for Samsung to provide high-performance image sensors to meet the increasingly diverse needs of the market.
On the other hand, Dual Pixel technology places two photodiodes side by side in a pixel and can receive light from different angles to detect phase. With this technique, even in low light conditions, the GN1 can instantly detect and focus stationary objects or move from any angle. Samsung is also taking advantage of that and offers an algorithm that can retrieve information from each photodiode to produce images with a resolution equivalent to 100 MP.
Samsung has also provided real-time Smart-ISO, HDR and EIS for ISOCELL GN1. This sensor supports 8K video recording at 30fps.
Mass production of new sensors has begun and we will soon see smartphones equipped with ISOCELL GN1.
