  • Dual Pixel Pro technology utilizes 100-million phase-detecting photodiodes that perceive phases both vertically and horizontally for faster and more accurate auto-focusing
  • Staggered HDR solution brings richer detail and more vibrant colors than real-time HDR, while reducing energy consumption by up to 24-percent

Samsung Electronics, a world leader in advanced semiconductor technology, 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.

For those who appreciate more detail in photographs or are prone to post-processing such as image cropping, the GN2 offers an option to take pictures in 100Mp resolutions. In 100Mp mode, the GN2 meticulously re-arranges the color pixels using an intelligent re-mosaic algorithm, creating three individual layers of 50Mp frames in green, red and blue. These frames are then up-scaled and merged to produce a single ultra-high 100Mp resolution photograph.

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 the 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 fewer motion-artefacts. 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.

Green pixels are split diagonally so the sensor can detect both vertical and horizontal phases. Canon will do the same in the R1 you have heard it here for the first time

Has canon licensed the dual pixel technology to samsung, or did I misunderstand?

I'm dreaming of a quadpixel or diagonal pixel AF with dualgain (more dr) backside illuminated (less noise) Canon sensor with global shutter ~20-24MP
I will give Canon about 5-7 years, then dynamic range and lowlight performance have to be visually better than my 5d mark iv, which is indeed very good, but maybe just because of the good glass (compared yo smartphones)?
So for me the R5 is a to minimalistic improvement for buying an R body since photography for me is just fun.
I mean the smartphone industry is now developing the image sensor of the future and canon should at least try to keep up with them.
Yes, I know pictures from modern smartphones look gread mostly because of software, the small screen, ...

Even I am confused it has been good 4-5 years since Samsung ia also advertising Dual Pixel AF on their topend phones and all white papers they published talk about same tech as Canon.

Google's line of Pixel smartphones also advertises dual pixel both in the name and technology, but use sensor from Sony. Sony apparently also has a patent on split photodiodes. Given how prominent Sony sensors are in smartphones, there are probably many more out there.

I've never found any explanation how it can be that basically everybody can use DPAF, and yet only Canon does it in ILC.
