Samsung has announced a new image sensor for smartphone cameras with the industry’s smallest pixels. The ISOCELL JN1 is a 50-megapixel sensor with a relatively small 1/2.76-inch format, meaning its pixels are only 0.64μm. For comparison, Samsung broke the record in 2019 with the slightly larger ISOCELL Slim GH1. which is another 50-megapixel sensor with 0.7μm pixels.
Common camera wisdom says that smaller pixels tend to result in worse image quality and higher noise. So why does Samsung do this? As the company said It’s all about form factor versatility. The sensor̵7;s smaller size means it can be used in ultra-wide or telephoto camera modules. which is difficult to design when the size is at a premium. or as a way to reduce the shock height of the main camera
Like other high-resolution camera sensors, the JN1 uses technology. Pixel-binning That combines multiple pixels into one for higher light sensitivity. In this case, Samsung says the sensor will capture 12.5 megapixel images with 1.28μm pixels, and the company also claims a 16% increase in light sensitivity thanks to ISOCELL 2.0 technology.
It’s unusual for Samsung to hold a livestream launch event for this sensor. which you can see here:
Samsung says the JN1 is in mass production. Therefore, it tends to appear in smartphones not too long.
