Samsung has ad a new image sensor for smartphone cameras which he says has the smallest pixels in the industry. The ISOCELL JN1 is a 50 megapixel sensor with a relatively small aspect ratio of 1 / 2.76 inch, which means its pixels are only 0.64m. For comparison, Samsung had already broken records in 2019 with the slightly larger ISOCELL Slim GH1, another 50 megapixel sensor with 0.7 µm pixels.
Conventional camera wisdom says that smaller pixels usually result in poorer image quality with higher noise, so why is Samsung doing this? According to the company, it’s all about the versatility of the form factor. The smaller size of the sensor means it can be used in ultra-wide or telephoto camera modules – which are difficult to design when size is everything – or as a way to reduce the height of the main camera bump.
As with other high-resolution camera sensors, the JN1 will use pixel clustering technology that combines multiple pixels into one for higher light sensitivity. In this case, Samsung claims that the sensor will capture 12.5 megapixel photos with the pixel equivalent of 1.28 µm, and the company also claims a 16% increase in light sensitivity with its ISOCELL 2.0 technology. .
Exceptionally, Samsung even hosted a full live launch event for this sensor, which you can watch here:
Samsung says the JN1 is currently in mass production, so it’s likely to appear in smartphones before too long.
