Samsung has just made the ISOCELL GN2 official, its new sensor with Dual Pixel Pro technology that uses 100 million photodiodes for phase detection focus. It is the successor to the ISOCELL GN1, a sensor introduced in May 2020 and which also specialized in low light photography with Dual Pixel architecture.
With this new generation, they want to reduce energy consumption and get even better photos. The sensor returns to bet on 50 megapixels and has several of the technologies used in larger sensors in the house, such as the ISOCELL HM3.
A new faster and more accurate sensor
The Samsung ISOCELL GN2 is a 50 megapixel sensor with 1.4 micrometer pixels. However, it uses Pixel Binning technology to group four pixels into one, simulate 2.8 μm pixels, and deliver photos with more light. In the same way, is capable of shooting at 100 megapixels.
The GN2 rearranges its pixels to obtain 100 megapixel photos, even if the sensor is 50. This is achieved creating three layers of RGB frames (red, green and blue) 50 megapixels, to later scale and merge those pixels into a high resolution image. Algorithms and AI at the service of the sensor, basically.
In this sensor Samsung highlights both the HDR and the Dual Pixel Pro, to focus faster than its predecessor
Similarly, Samsung highlights its Dual Pixel Pro approach, your latest phase detection focusing solution. Two photodiodes are used for each pixel of the image sensor, achieving 100 million active photodiodes to focus. With this technology Samsung promises to improve focusing both in low light and in motion, where each pixel of the sensor acts as a focusing agent.
Finally, HDR photographs stand out. The GN2 promises greater dynamic range than its predecessor, while reducing energy consumption by 24%, according to Samsung. HDR is also supported by the implementation of Smart ISO and Smart ISO Pro, the technology Samsung uses to combine high and low ISO images to achieve greater dynamic range.
