Samsung announces new 50MP ISOCELL GN1 sensor with large pixels and fast focus


Samsung continues to expand modela number of sensors for smartphones and officially announces the launch of the new ISOCELL GN1 photo sensor, optical format 1 / 1.31 ″. The developers note that the sensor has two key advantages: large pixels with a size of 1.2 microns and support for two technologies at once: Dual Pixel and Tetracell.

Using large pixels in the GN1 sensorallows, according to Samsung engineers, to take photography to a whole new level, providing high sensitivity when shooting in low light conditions and ultra-fast autofocus necessary for working with dynamic scenes and comparable to SLR cameras.

Cameras in modern smartphones are developed withhigher resolution, which reduces the actual size of the pixels. The race of megapixels is becoming increasingly intense, so the transition from 64 megapixels to 108 megapixels for Samsung took no more than six months. In the latest flagship Galaxy S20 Ultra, a 108 megapixel sensor was installed, the dimensions of which are two times larger than the 12 megapixel sensor in the iPhone 11 Pro. In the near future, a photo sensor developed by Samsung with a resolution of 150 megapixels may also enter the market, and in the future, work has already been announced on a 600 megapixel sensor.

In the global market for camera sensorssmartphones, the main competitor of Samsung is Sony Corporation, which recently announced the new Sony IMX689 sensor (48 megapixels, 1.22 μm pixel size) already running in the Oppo Find X2 Pro smartphone. The new ISOCELL GN1 sensor (50 megapixels) is the answer to the novelty of Japanese developers. Using the technology of merging four neighboring pixels, known as Tetracell, the GN1 sensor will actually take pictures at a resolution of 12.5 megapixels, and the pixel size will increase to 2.4 microns.

Technology Dual Pixel, which has become one of the mainGN1 provides a solution to the focusing problems that have already appeared on the Galaxy S20 Ultra models, where these features have not been implemented. In the flagship S20 Ultra, developers had to get out of a difficult situation by creating additional software updates.

ISOCELL GN1 sensors will be the fastest amongexisting photosensors automatic phase focusing. Using Dual Pixel technology, two photodiodes are placed in one pixel, receiving light from different angles in a certain phase. This allows the sensor to focus on a stationary or moving object almost instantly, at any angle, even in low light conditions. A software algorithm has also been developed that allows receiving light information from each photodiode and forming a photo in high resolution, similar to 100 megapixels.

ISOCELL GN1 sensor implements supportSmart-ISO technology to automatically adjust the sensitivity depending on the lighting. The sensor allows electronic stabilization and video recording in 8K resolution at a speed of 30 frames / sec. Samsung will start mass production of ISOCELL GN1 sensors this month, and therefore smartphones with a new sensor will soon enter the market.
