Samsung unveils new 50 MP ISOCELL GN2 sensor

Samsung has unveiled its brand new camera sensor, the ISOCELL GN2. Today introduced Samsung ISOCELL GN2, a new 50-megapixel (Mp) image sensor with large 1.4-micrometer (μm)-sized pixels. With enhancements to its predecessor, the ISOCELL GN1, the GN2 offers up to 100Mp imaging, improved auto-focusing through Dual Pixel Pro technology, powerful staggered HDR, and vivid results through Smart ISO Pro, regardless of the lighting environment.

“ISOCELL image sensors and its technologies have made vast improvements to deliver the quality and performance one would expect from top-tier prograde cameras,” said Duckhyun Chang, executive vice president of sensor business at Samsung Electronics. “Our new ISOCELL GN2 features Dual Pixel Pro, an innovative all-direction auto-focusing solution that elevates the agility to capture moments as they unfold. Adding on Smart ISO Pro and a variety of advanced pixel technologies, pictures from GN2 are more true-to-life than ever.”

The 1/1.12-inch ISOCELL GN2 is a highly versatile image sensor when it comes to image resolutions. With 50 million 1.4μm-sized pixels on hand, the GN2 offers exceptionally detailed photographs in regular settings. In low-lit environments such as indoors, the sensor can simulate a larger 2.8μm-pixel with four-pixel-binning technology to absorb more light, delivering brighter and sharper images.

The ISOCELL GN2 is Samsung’s first image sensor to offer Dual Pixel Pro, the company’s most advanced phase-detection auto-focus solution yet. By employing two photodiodes within every pixel of the image sensor, Dual Pixel Pro makes use of one hundred million phase detecting agents for ultra-fast auto-focusing. In addition, the solution also offers all-direction focusing by splitting the pixels not only vertically, as with Dual Pixel, but also diagonally. This diagonal cut allows the focusing agents to better recognize the top and bottom of the frame, allowing the sensor to get in focus quickly even when there are no pattern changes in a horizontal direction. Low-light focusing and tracking of moving objects are improved as well, as every pixel of the sensor works as focusing agents.

For taking pictures in mixed-light environments, such as sunsets or indoors with daylight coming through a window, the GN2 increases its dynamic range with a staggered-HDR feature, a time-multiplexed HDR technology that uses rolling shutters over the same pixel arrays to capture multiple frames in short, middle, and long exposures. By maximizing the dynamic range, staggered-HDR ensures rich detail and vivid color in highlights and dark shadows within the scene, making it an ideal solution for shooting high-contrast sights. Staggered-HDR is able to reduce the energy consumption of a sensor by up to 24-percent when compared to the predecessor’s real-time HDR mode, contributing to improved energy efficiency of the overall system.

The GN2 also comes with Smart ISO and Smart ISO Pro. Smart ISO intelligently sets the sensor’s conversion gain, allowing the picture to be taken using an optimal ISO; low ISO for brighter outdoors or high for dimmer indoors. Unlike Smart ISO, which uses readouts from a single ISO per picture, Smart ISO Pro, which uses an intra-scene dual conversion gain (iDCG) solution, takes readouts from both high and low ISO to instantly create high dynamic range images with less motion-artifacts. In addition, 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 and taking mobile night photography to greater heights.

Camera experiences can be more fun and creative with the GN2, where precious moments can be captured more dramatically and everyday events can be turned into short videos. The GN2 supports full-HD videos at 480 frames-per-second (fps) or 4K at 120fps, enabling wider possibilities for mobile video-shooting. Samsung ISOCELL GN2 is currently in mass production.
