BusinessWire, BusinessWire: Samsung introduces ISOCELL GN1, a new 50MP sensor with 1.2μm pixels. The ISOCELL GN1 is Samsung’s first image sensor to offer both Dual Pixel and Tetracell technologies.

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,” said Yongin Park, EVP of sensor business at Samsung. “We will continue to introduce image sensor solutions at the cutting-edge that will lead the next trends in mobile photography.

The GN1 auto-focuses with 100 million PDAF agents. 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 AF 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 EIS. The image sensor supports video recording at up to 8K resolution at 30fps.

Samsung ISOCELL GN1 has started mass production this month.
