The Korean company officially announced a new generation of ISOCELL GN1 sensor, that can integrate dual-pixel focusing and Tetracell pixel clump technology.
The new sensor, named ISOCELL GN1, is the first model in the ISOCELL series to offer both dual-pixel focusing technology and tetra cell pixel aggregation. The old-style pixel sensor models such as GM1 (48MP), GW1 (64MP), HMX, and HM1 (108MP) only have the traditional PDAF focus but cannot integrate dual-pixel. This is also one reason for the disappointing AF performance of the Galaxy S20 Ultra with ISOCELL HM1.
50 megapixels specialized in low light and Dual Pixel architecture
The GN1 is the first ISOCELL sensor to integrate a dual-pixel focus with Tetracell
However, with GN1, Samsung immediately integrated dual pixels together with pixel aggregation, such as the IMX689 sensor that Sony developed specifically for Oppo Find X2 Pro. According to Samsung, the sensor will take impressive underexposed photos thanks to Tetracell, which combines 4 pixels in one, while still offering a focusing speed that reaches the level of a DSLR thanks to Dual Pixel.
“ISOCELL GN1 is a guarantee of incredible image quality under all circumstances,” claims the Executive Vice President of Samsung Sensor. In addition to successfully integrating dual pixel focus into a pixel sensor, Samsung also promises a new algorithm that can process the light information from each diode on the sensor and then output the image at 100MP resolution.
The new sensor has a resolution of 50MP, almost half of the 108MP sensor of the Galaxy S20 Ultra
In terms of specifications, the GN1 sensor has a resolution of 50MP (8,160×6,144) at a size of 1 / 1.3 inches. The pixel is 1.2 microns in size, and when they are 2.4 microns together, the resolution is reduced from 50MP to 12.5MP, improving sensitivity for better images in low light conditions. 8K video can be recorded at 30 fps, 1080p @ 240 fps. Other technologies include Smart ISO, real-time HDR, and EIS.
Samsung says the sensor will begin mass production this month. It is not clear which smartphone company will use it first, nor is it clear whether the Galaxy Note 20 will use the new GN1 sensor immediately. Earlier rumors say that Samsung’s next flagship will still use the same camera configuration as the Galaxy S20 Ultra, i.e. a 108MP sensor without dual pixel.
