Samsung Introduces New Camera Sensor Combining Dual Pixel and Tetracell Technologies

Samsung has developed and introduced the new ISOCELL GN1 camera sensor to meet the growing needs in smartphone cameras. ISOCELL GN1, Samsung's first sensor with a pixel size of 1.2 micrometers, offers the company's Dual Pixel and Tetracell technologies together.


Accelerating their work on smartphone cameras, Samsung announced the company's first 50-megapixel ISOCELL GN1 sensor with a pixel size of 1.2 micrometers

(μm) . ISOCELL GN1 also stands out as Samsung's first image sensor to offer both Dual Pixel and Tetracell technologies.


Samsung's Dual Pixel and Tetracell technologies promise low-light photos and DSLR-level autofocus speeds optimized for more dynamic photo experiences. The sensor has 100 million phase-sensing pixels on its surface , enabling faster and more accurate autofocus.


Samsung ISOCELL GN1 combines Dual Pixel and Tetracell technologies

Dual Pixel technology places two photodiodes side by side in a single pixel that can receive light from different angles for phase detection. In this way, ISOCELL GN1 can instantly focus a still object from every corner even in low light conditions. When shooting images, a single pixel output is created by combining the outputs from the two photodiodes within the pixel . In addition, the software algorithm receives light information from each photodiode to produce image resolutions comparable to 100 MP.

Tetracell technology is a pixel combining technique that increases the capacity of pixels to capture and process light. Combining four pixel signals, Tetracell quadruples the light sensitivity to take brighter 12.5 MP photos by increasing the pixel size of the image sensor to 2.4 μm. With enhanced light sensitivity combined with a powerful autofocus solution, the GN1 can quickly focus on an object even in extremely low-light environments to achieve brighter and sharper results.


ISOCELL GN1 supports video recording up to 8K resolution at 30 frames per second . Smart-ISO somehow manages optimal ISO, real-time HDR, and gyroscope-based electronic image stabilization (EIS) that captures sharp images and videos on the go, capturing the scene in multiple exposures at the same time. Samsung announced that they started mass production of ISOCELL GN1 this month. So we can expect to see the new sensor on smartphones soon.
