Samsung ISOCELL GN2 50MP sensor announced with Dual Pixel Pro (AF) technology

Samsung ISOCELL GN2

Samsung is introducing its new camera sensor — the 50MP ISOCELL GN2. This new sensor comes as a direct successor to the ISCOELL GN1, launched last year. In comparison, the successor attains significant improvements when it comes to sensor size and pixel size. The ISOCELL GN2 features a 50MP (1/1.12-inch) image sensor coupled with larger 1.4μm sized pixels. Currently, the ISOCELL GN2 is said to be in mass production, which means we can expect the new sensor to feature in smartphones coming later this year.

Samsung 50MP ISOCELL GN2 — Key features

Firstly, it’s a 50MP sensor, which offers up to 100MP as the predecessor; however, comes with a new Dual Pixel Pro technology. This involves bringing significant improvements on autofocusing: and new features involving staggered HDR coupled with Smart ISO Pro, which ought to bring vivid results regardless of lightning conditions, Samsung implies.

Dual Pixel Pro

New Dual-Pixel Pro-tech from Samsung is said to be a more advanced version of the current PDAF (Phase detection autofocus) solution. This tech involves two photodiodes within every pixel of the image sensor for quicker AF totalling up to one million phase detecting agents utilisation. Besides, the ultra-fast focus delivers all-direction focusing with pixel splitting, both vertically and diagonally.

The ISOCELL GN2 claims to be a versatile image sensor offering detailed photos in regular settings. And, further, in lower lighting conditions, the sensor has the ability to stimulate 2.8μm pixel with four-pixel binning technology; that promises to absorb more light and deliver sharper/brighter images.

100MP Photos

The 100MP photos are created in three layers comprising — 50MP frames in green, red, and blue, which are then rearranged using Samsung’s intelligent re-mosaic algorithm; further upscaled, merged to create the high-resolution image.

Staggered HDR

The staggered HDR feature, on the ISOCELL GN2, claims to increase the dynamic range; using rolling shutters to capture multiple frames in short, middle, and long exposures. The staggered HDR further promises to reduce the energy consumption of a sensor by 24%, Samsung suggests.

Smart ISO and Smart ISO Pro

On the ISOCELL GN2, Smart ISO uses Optimal ISO; meaning low ISO for bright outdoors or higher ISO for low light indoors. Smart ISO Pro, on the other hand, utilises an intra-scene dual conversion gain (aka iDCG) solution. This includes taking readouts from high and low ISO readings that promises to create higher dynamic range images with fewer motion artefacts. The Smart ISO Pro further ought to be helping in taking better night photographs by quickly capturing and processing multiple frames in high ISO; and raising the light sensitivity close to one-million ISO, according to Samsung.

Lastly, when it comes to mobile video shooting, the GN2 sensor supports Full HD recording at 480fps, and 4K recording at 120fps.
