Samsung Announces 1.4μm 50Mp ISOCELL GN2 with Faster and More True-to-Life Auto-Focusingby dhiram
Samsung 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.
The 1/1.12-inch ISOCELL GN2 with 50 million 1.4μm-sized pixels on hand, 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.
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. 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.
