Samsung had recently unveiled its new ISOCELL GN1 50 megapixel image sensor with 1.2μm pixels. What’s notable about this sensor is that it combines both the Tetracell and Dual Pixel technology to bring improved camera performance.

The new ISOCELL GN1 sensor delivers excellent performance that can nearly rival professional grade images in almost any environment, according to Samsung. In other words, it is useful in low light conditions, where it uses the 4:1 pixel binning technology to sharpen images with less noise. Furthermore, it also offers ultra fast autofocus which is apparently just as good as the ones found in DSLR cameras.

The fast autofocus time means that shots can be taken quicker, which is achieved thanks to the Dual Pixel technology. Samsung’s ISOCELL GN1 sensor manages to pull this off through algorithms that enable image quality to be on par with 100 megapixel resolution shots. Notably, the South Korean tech giant stated that higher resolution sensors typically employ 0.8μm pixels, which is smaller than the GN1’s pixels. In other words, the latter has an advantage during night time.

Furthermore, the Samsung GN1 sensor also utilizes ISOCELL Plus, which uses barriers to isolate individual pixels. This enables micro lens to allow more light into the pixel’s photodiodes, which in turn, improves color fidelity and offers more accurate color reproduction as well. The images are captured in 8,160 x 6,144 resolutions while its pixels uses Samsung’s real time HDR to capture better shadows, mid tones, and highlights.

South Korean giant Samsung has today announced its new 50-megapixel image sensor named Samsung ISOCELL GN1, making it the company’s first camera sensor to come with both Dual Pixel and Tetracell technologies.

The new Samsung ISOCELL GN1 is a 1/1.31-inch sensor that offers 1.2μm-sized pixels. It comes with 100 million phase-detection auto-focus (PDAF) agents. With both Dual Pixel and Tetracell technologies, the company seems to be prioritising high-resolution images and fast autofocus speed for smartphone users.

The sensor has Tetracell technology for 4-in-1 pixel binning, while the in-house ISOCELL Plus technology is said to keep pixel cross-talk in check, minimize optical loss, and produce more detailed images.

There’s also something called Smart-ISO which present to reduce noise and enhance the dynamic range. Other features include Real-time HDR, gyro-based image stabilization, 8K/30fps recording, and 400fps video at 1080p without autofocus and 240fps with autofocus support.

Samsung GN1 is capable of producing images up to 100MP resolution, thanks to the pixel binning technology. Explaining the working, Samsung says that Dual Pixel technology places two photodiodes side-by-side within a single pixel that can receive light from different angles for phase detection. With active pixels working as auto-focusing agents, the sensor can detect and focus onto a desired still or moving object from every corner in an instant, even in low-light conditions.

The camera sensor seems to be a rival the 48-megapixel Sony IMX689 image sensor which is present in several flagship smartphones such as OnePlus 8 Pro and OPPO Find X2 Pro. It remains to be seen if the company uses this sensor for its upcoming Note-series devices or the foldable smartphones.

The ISOCELL GN1 from Samsung will enter into mass production later this month so we expect smartphones packed with this new camera sensor to be available in the market from the second half of this year.
