Samsung’s new 50 megapixel camera sensor has the smallest pixels yet

Samsung is pushing the boundaries of pixel sizes again with its latest smartphone camera sensor. Isocell JN1 fits 50 megapixels in a small 1 / 2.76-inch format for a pixel size of only 0.64 micrometers. It is significantly smaller than the 0.7 micrometer pixels found on its 43.7-megapixel Isocell Slim GH1 sensor, which was released back in 2019. “The new 0.64 μm Isocell JN1 will be able to equip tomorrow’s ultra – high – resolution smartphones with mobile photographers, “said Samsung Director of Electronics, Duckhyun Chang.

The small sensor size will be useful for multi-camera setups and allow smartphone designers to use the sensor for front-facing, ultra-wide, telephoto or standard cameras depending on the setup and resolution required. It will also reduce the thickness of the camera module by about 1

0 percent, Samsung said.

The problem with small pixels is that they cannot collect as much light as larger pixels. So for shooting in low light, the sensor combines four pixels in one, which increases the light four times, while the sensor resolution is reduced to 12.5 megapixels. In addition, it uses Samsung’s new Isocell 2.0 technology, which replaces metal barriers between color filters with a material that reduces light loss, increasing sensitivity up to 16 percent.

The new sensor also includes Samsung’s “dual super PD” (phase detection) autofocus with twice phase detection pixel density, which improves AF performance in low light situations. The new sensor also supports 4K video at 60 fps or full HD at 240 fps. Samsung said the JN1 is now in mass production, so expect it to appear in new smartphones soon.
