Samsung has announced a new 50-megapixel camera sensor designed to ensure that smartphones that use it in the future take better photos. The Isocell GN1 is Samsung’s first sensor with Tetracell pixel binning and dual-pixel autofocus.

In the news: South Korean technology giant Samsung has introduced the Isocell GN1. This 50 MP camera sensor is the first of its kind in the Samsung range.

What preceded? In February of this year, Samsung introduced the Galaxy S20 Ultra. It had an impressive 108-megapixel camera, but many users soon complained. The device appeared to have problems with focusing, so photos are often not sharp.

  • About the same period, competitor came Sony with the IMX700. That is used in the Huawei P40 (Pro) and seems to suffer less from focus problems.
  • The predecessor, the Sony IMX689, can also be seen as a competitor for Samsung. That sensor is used in the OnePlus 8 Pro, among other things.

The details: Reason enough for Samsung to put its developers to work with a better camera sensor on the market. This should ensure better photos in low light and faster autofocus.

  • The Isocell GN1 has a maximum resolution of 50 megapixels with large pixels of 1.2 μm.
  • It is the company’s first camera sensor to feature Tetracell pixel binning and dual-pixel autofocus.
    • The Tetracell technology is a technique that merges pixels to improve the ability of the pixels to more light capture and process. In this way, the pixel size is doubled to 2.4 μm and the light sensitivity is quadrupled.
    • The dual-pixel technology places two photodiodes side by side in a single pixel. So can the sensor detect and focus on a stationary or moving object very quickly and from all angleseven in low light.
    • Via Samsung software, the dual-pixel technology can also be used in reverse. Then you always use both photodiodes in each pixel to have photos on one image resolution comparable to 100 megapixels.
  • In addition, the Isocell GN1 has many other interesting technologies.
    • Smart-ISO determines the ideal ISO value itself.
    • Real-time HDR automatically captures the image in multiple exposures.
    • The electronic image stabilization (EIS) ensures sharp images and videos, even when you are moving.
  • The sensor supports video recordings up to 8K On 30 frames per second (fps).
  • Samsung has already started mass production of the Isocell GN1. It is not clear when and in which device it will be used for the first time.
