Samsung Introduces 1.2μm 50Mp ISOCELL GN1 With Faster Auto-focusing and Brighter Images

Samsung Introduces 1.2μm 50Mp ISOCELL GN1 With Faster Auto-focusing and Brighter Images

Cameras May 20,2020 0

Samsung Electronics introduced Samsung ISOCELL GN1, a new 50-megapixel (Mp) image sensor with large 1.2μm-sized pixels.

he ISOCELL GN1 is Samsung’s first image sensor to offer both Dual Pixel and Tetracell technologies. Thanks to the relatively larger pixel size, the GN1 promises to bring image sensor performance to a new level with a combination of elevated light sensitivity for stellar low-light photos and DSLR-level auto-focus speeds, optimized for more dynamic picture-taking experiences.

To address various imaging preferences of the users, some smartphone makers put more emphasis on extremely detailed images with ultra-high resolutions, while some choose bigger pixels for bright results in low-light environments. Samsung says that its ISOCELL GN1 fulfills these multiple needs at once with Dual Pixel and Tetracell technologies.

The GN1 brings great auto-focusing with 100 million phase detection auto-focus (PDAF) agents. Samsung’s Dual Pixel technology places two photodiodes side-by-side within a single pixel that can receive light from different angles for phase detection. With all of the sensor’s active pixels working as auto-focusing agents, the GN1 can detect and focus onto a desired still or moving object from every corner in an instant, even in low-light conditions. When capturing images, a single pixel output is created by merging the outputs from the two photodiodes within the pixel. Samsung also provides a software algorithm that takes light information from each photodiode to produce image resolutions comparable to 100Mp.

For low-light photography, the GN1 adopts Tetracell technology, a pixel-merging technique that improves the pixels’ capacity to capture and process more light. By binning four pixel signals into one, Tetracell doubles the image sensor’s pixel size to 2.4μm and quadruples the light sensitivity to take brighter 12.5Mp photographs.

In addition to Dual Pixel and Tetracell technologies, the GN1 comes with Smart-ISO that intelligently selects the optimal ISO, real-time HDR that captures the scene in multiple exposures simultaneously, and gyro-based electronic image stabilization (EIS) that takes sharp images and video even when in motion. For premium video quality, the image sensor supports video recording at up to 8K resolution at 30 frames-per-second (fps).

Samsung ISOCELL GN1 started mass production this month.
