Samsung unveils ISOCELL GN2 photo sensor with improved autofocus and low light performance


Digital image sensors areone of the most dynamically developing segments of the high technology market. The ever-growing number of sensors on smartphones and the popularity of digital photography provide high income for manufacturers. The leaders in this industry are Sony, which controls 44% of the market and Samsung is rapidly catching up with the Japanese (32%).

The Korean company has been able in recent yearssignificantly expand the range of digital image sensors, supplying to the market sensors with a resolution from 32 to 108 megapixels. In parallel, there is a constant introduction of new technologies and continuous improvement of sensors. Samsung recently announced the start of mass production of the 50MP ISOCELL GN2 sensor to replace the ISOCELL GN1 sensor released last year.

While maintaining the pixel count, engineersSamsung has been able to achieve significant improvements in photo quality by making significant changes to the sensor. The new ISOCELL GN2 will increase the pixel size to 1.4 microns and the sensor itself to 1 / 1.2 inches. Together with 4-in-1 pixel binning technology, which increases the pixel size to 2.4 microns, the innovation will significantly improve image quality when shooting in low light conditions.


Another innovative step by Samsung wasthe use of a hybrid 100 Mp mode, in which, using the remosaic algorithm, three independent 50 Mp image layers of a frame of green, red and blue colors are created, with their subsequent scaling up to 100 Mp high resolution photos.

Introduced in ISOCELL GN2 sensor also newDual Pixel Pro technology for phase detection autofocus (PDAF). The use of vertical and horizontal pixel separation provides omnidirectional focusing with increased performance and better performance in low-light subjects. The introduction of Dual Pixel Pro greatly improves the tracking of moving subjects.

Shooting performance is also improvedin HDR mode for high contrast scenes with high dynamic range using the shifted HDR function. It captures multiple shots at short, medium and long exposures using the roller shutter, and then takes a high quality shot with a unique balance of highlights and shadows.


Using ISOCELL GN2 Sensors Smart FeaturesISO will allow the camera to operate at both high and low ISO values ​​to quickly create high dynamic range images with minimal motion artifacts. Continuing the implementation of Smart ISO Pro will improve the quality of shooting in extremely low light conditions by shooting and processing multiple frames at high ISO values.

ISOCELL GN2 sensor enables shooting8K, 1080p video at 480fps or 4K at 120fps. Currently, Samsung has already launched mass production of new sensors, but the company does not say on which devices and when exactly the new product will appear. However, there is information that the first ISOCELL GN2 sensor is used by Xiaomi in its future smartphone Mi 11 Ultra.
