Samsung Electronics, today introduced Samsung ISOCELL GN2. It is a new 50-MP image sensor with large 1.4-mm (μm)-size pixels. This sensor succeeds the ISOCELL GN1 sensor on many smartphones. Moreover, it integrates a new Dual Pixel Pro technology. GN2 offers up to 100MP imaging and improved auto-focusing through Dual Pixel Pro technology. In addition, it also offers powerful staggered HDR, and vivid results through Smart ISO Pro, regardless of the lighting environment.

Additionally, Samsung says the new staggered HDR feature has reduced energy consumption by up to 24 percent. However, the company says that the ISOCELL GN2 sensor is currently in mass production. There is no confirmation on the launch date as of yet or which smartphone it will integrate into.

The new ISOCELL GN2 sensor from Samsung has a 50-MP image sensor. It also comes with Smart ISO Pro to offer better results in low light conditions. Moreover, the 1/1.12-inch ISOCELL GN2 sensor can simulate a larger 2.8-micron pixel with four pixel-binning technology to absorb more light in low-light conditions. The sensor also offers an option to take pictures in 100-MP resolutions. The 100-MP mode rearranges the color pixels using an intelligent re-mosaic algorithm. This, in turn, creating three individual layers of 50-MP frames in green, red, and blue. These frames are then up-scale and merge to produce a single ultra-high 100-megapixel resolution photograph.

Dual Pixel Pro technology on the Samsung ISOCELL GN2 sensor offers accurate and fast auto-focusing. Samsung also claims that it is the company’s most advanced phase-detection auto-focus solution yet. It offers all-direction focusing by splitting the pixels not only vertically, as with Dual Pixel, but also diagonally. Moreover, Dual Pixel Pro enables improved low-light focusing and tracking of moving objects as well, as every pixel of the sensor works as focusing agents.

Additionally, there is a new staggered HDR feature integrated that uses rolling shutters in ISOCELL GN2. Compared over the same pixel arrays to capture multiple frames in short, middle, and long exposures. By maximizing the dynamic range, staggered HDR is able to offer rich detail and vivid color in highlights. It also adds dark shadows within the scene, the company claims. Samsung says staggered HDR is able to reduce the energy consumption of a sensor by up to 24% when compared to the predecessor’s real-time HDR mode.

Samsung’s new ISOCELL GN2 sensor also has Smart ISO and Smart ISO Pro support to elevate light-sensitive photos. For instance, in extreme low-light, Smart ISO Pro quickly takes and processes multiple frames in high ISO, raising the light sensitivity close to one-million ISOs. The GN2 supports full-HD videos at 480 fps or 4K at 120fps.
