Samsung’s 50MP ISOCELL GN2 camera sensor provides enhanced autofocus, HDR



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

ISOCELL GN2 is a 1 / 1.12-inch camera sensor with 50MP resolution and 1.4 μm pixels. It supports 4-in-1 pixel binding (effectively 12.5 MP images with 2.8 μm pixels) to offer impressive performance in low light conditions. The new camera sensor also has the ability to use its intelligent re-mosaic algorithm to capture three 50 MP frames (red, green and blue) and create a 100 MP image for higher details.

The South Korean technology company is also introducing its new autofocus technology called Dual Pixel Pro for the first time with ISOCELL GN2. The new sensor has hundreds of millions of phase detection means for ultra-fast focusing. Furthermore, it uses not only vertical but also diagonal focusing for more reliable performance, and helps in situations when a frame does not have pattern changes in the horizontal direction. This results in better focusing in low light conditions and on moving objects compared to ISOCELL GN1.

ISOCELL GN2 has also shifted HDR, which ensures that images have a higher dynamic range than HDR in real time. Scenes that have both light and dark areas are captured with rich details and vibrant colors, thanks to offset HDR. The new HDR mechanism also uses 24% lower energy compared to real-time HDR. The new camera sensor also has Smart ISO and Smart ISO Pro for improved light sensitivity and dynamic range.

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

Duckhyun Chang, executive vice president of sensor operations at Samsung Electronics, said: “ISOCELL image sensors and its technologies have made major improvements to deliver the quality and performance one would expect from top quality prograde cameras. Our new ISOCELL GN2 has Dual Pixel Pro, an innovative autofocus solution in all directions that increases the agility to capture moments as they unfold. By adding Smart ISO Pro and a host of advanced pixel technologies, images from GN2 are more real than ever.
