Samsung’s 50MP ISOCELL GN2 Camera Sensor Offers Enhanced Autofocus, HDR


Samsung had unveiled its 50MP ISOCELL GN1 camera sensor last year, providing a perfect balance of high megapixels, large pixel size, and autofocus speed. Today, the company has announced a successor to its first-generation 50MP camera sensor in the form of the ISOCELL GN2. This 50MP sensor offers even faster autofocus and improved HDR performance.

The ISOCELL GN2 is a 1 / 1.12-inch camera sensor with a resolution of 50 MP and pixels of 1.4 μm. Supports 4-in-1 pixel binning (12.5 MP images with 2.8 μm pixels) for impressive low-light performance. The new camera sensor also has the ability to use its smart mosaic algorithm to capture three 50MP frames (red, green, and blue) and create a 100MP image for more detail.

The South Korean tech firm is also unveiling its new autofocus technology called Dual Pixel Pro for the first time with the ISOCELL GN2. The new sensor has 100 million phase detecting agents for ultra-fast focusing. In addition, it uses not only vertical but also diagonal focus for more reliable performance, which helps in conditions where a frame has no pattern changes in the horizontal direction. This results in better focus in low light conditions and on moving subjects compared to the ISOCELL GN1.

The ISOCELL GN2 also features tiered HDR, which ensures that images have a higher dynamic range than HDR in real time. Scenes that have bright and dark areas are captured with rich details and vivid colors, thanks to tiered HDR. The new HDR mechanism also consumes 24% less power compared to real-time HDR. The new camera sensor also features Smart ISO and Smart ISO Pro to improve light sensitivity and dynamic range.

Samsung’s next-generation 50MP camera sensor can also capture Full HD video at up to 480fps and 4K video at up to 120fps. The company has already started mass production of the ISOCELL GN2 camera sensor, and we can expect it on newer smartphones later this year.

Duckhyun Chang, Executive Vice President of Sensor Business at Samsung Electronics, said: “ISOCELL image sensors and their technologies have made great improvements to deliver the quality and performance that one would expect from top-tier programmed cameras. Our new ISOCELL GN2 features Dual Pixel Pro, an innovative all-directional autofocus solution that increases agility in capturing moments as they unfold. By adding Smart ISO Pro and a variety of advanced pixel technologies, GN2 images are more lifelike than ever.
