Today, Samsung Electronics announced the launch of Samsung ISOCELL GN1. This is a new 50MP image sensor with large pixels of 1.2 μm. ISOCELL GN1 is Samsung’s first image sensor that provides both dual-pixel and Tetracell technology. Due to its relatively large pixel size, GN1 takes the performance of the image sensor to a new level. It combines high sensitivity to stellar low-light photos with DSLR-level autofocus speed. It’s major focus is on improving the dynamic photography experience. According to reports, the Samsung ISOCELL GN1 is already in mass production.
Some manufacturers focus on image quality with ultra-high resolution. However, others choose larger pixels to obtain bright effects in low-light environments. The new Samsung ISOCELL GN1 meets these needs with its Dual Pixel and Tetracell technology.
Samsung ISOCELL GN1 50MP sensor features
The Samsung ISOCELL GN1 supports 100 million phase detection autofocus (PDAF). Samsung’s dual-pixel technology places two photodiodes side by side in a pixel and can receive light from different angles for phase detection. With the help of all the active pixels of the sensor as an auto-focusing agent, even under low light conditions, GN1 can still instantly detect and focus on the desired stationary or moving objects from every corner.

When capturing an image, a single-pixel output is created by combining the outputs of the two photodiodes in the pixel. Samsung also provides a software algorithm that obtains light information from each photodiode to produce an image resolution comparable to 100MP.
For the final low-light photography, GN1 uses Tetracell technology. This is a pixel merging technology that improves the ability of pixels to capture and process more light. By combining the four-pixel signals into one, Tetracell doubled the pixel size of the image sensor to 2.4 μm and increased the photosensitivity by four times to take a brighter 12.5MP photo. With better sensitivity and a powerful autofocus solution, the GN1 can quickly focus on objects even in extremely low-light environments.
In addition to dual pixels and Tetracell technology, GN1 also has Smart-ISO. This technology can intelligently choose the best ISO, real-time HDR (capable of capturing multiple exposure scenes simultaneously), and gyro-based electronic image stabilization (EIS) to take clear images. In order to obtain excellent video quality, the image sensor supports 8K / 30 frames (fps) to record video.
