Samsung named its new 50-megapixel sensor ISOCELL GN2 Unveiled with better performance in autofocus and HDR than the previous generation.
With the introduction of the ISOCELL GN1 50-megapixel sensor in early 2020, Samsung struck the perfect balance between high megapixels, large pixel size and fast autofocus. The Korean manufacturer now replaces this sensor with the name ISOCELL GN2 Unveiled Like the previous generation, it has 50 megapixels, but has improved the autofocus and HDR performance even more.
ISOCELL GN2 is a 1.12-inch camera sensor with a resolution of 50 megapixels and a pixel size of 1.4 microns. The sensor uses 4-in-1 pixel combination technology (creating 12.5-megapixel images with a pixel size of 2.8 microns) to improve camera performance in low-light environments. It also uses the intelligent mosaic algorithm to capture three 50-megapixel frames (red, green, and blue), creating a 100-megapixel image with more detail.
The new sensor is the first to benefit from Samsung’s new autofocus technology called Dual Pixel Pro, and its speed in autofocus has been significantly improved. For more stability, in addition to horizontal focus, it also uses oblique focus and improves sensor performance when a frame does not have a pattern of vertical changes. This feature provides better focus in low light environments and moving objects compared to the previous generation sensor.
The ISOCELL GN2 also features staggered-HDR, which uses a rolling shutter to capture images at different exposures. Samsung says it uses 24 percent less power than most real-time HDR sensors used in most sensors, but also improves sensor performance in capturing shadows and highlights. This product also has Smart ISO and Smart ISO Pro capabilities to improve light sensitivity and dynamic range.
Samsung’s new 50-megapixel sensor is capable of shooting Full HD video at up to 480 frames per second and 4K video recording at 120 frames per second. Samsung says it has begun mass production of the sensor, and the first handsets will be available this year.
