Samsung 50MP ISOCELL GN1 image sensor with dual pixel autofocus announced

Samsung 50MP ISOCELL GN1 image sensor's mass production began earlier this month

  • ISOCELL GN1 image sensor is the first from Samsung to offer both Dual Pixel and Tetracell technologies
  • The new Samsung image sensor supports 8K video recording at 30fps

Samsung Electronics has announced a new ISOCELL GN1 50MP image sensor with large 1.2μm-sized pixels. It is the first sensor from the South Korean giant to offer both Dual Pixel and Tetracell technologies. Leveraging on the relatively larger pixel size, the new GN1 sensor improves the performance by combining the elevated light sensitivity for better low-light images and DSLR-level autofocus speed. The new image sensor brings 100 million phase-detection autofocus agents, while the Dual Pixel technology places two photodiodes side-by-side within a single pixel that can receive light from different angles for phase detection. While capturing images, a single-pixel output is created by merging the outputs from the two photodiodes within the pixel, and Samsung provides a software algorithm that takes light information from each photodiode to produce images that are comparable to 100MP resolution.

Tetracell technology is a pixel-merging technique that improves the pixels’ capacity to capture and process more light. It combines four-pixel signals into one, thereby doubling the image sensor’s pixel size to 2.4μm and quadruples the light sensitivity to take brighter 12.5MP photos. The GN1 sensor comes with smart-ISO that 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. The sensor also supports 8K video recording at 30fps. Samsung has begun the mass production of the ISOCELL GN1 sensor this month.


Yongin Park, Executive Vice President — Sensor Business, Samsung Electronics, said, “With innovative pixel technologies, Samsung has been at the forefront of offering high-performance image sensors that closely cater to increasingly diversifying market needs. The ISOCELL GN1 is part of that commitment to deliver stunning images to consumers in any environment. We will continue to introduce image sensor solutions at the cutting-edge that will lead the next trends in mobile photography.”
