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

Samsung is pushing the limits of pixel size even further with its latest smartphone photo sensor. the Isocell JN1 fits 50 megapixels into a small 1 / 2.76 inch format for a pixel size of just 0.64 microns. That’s considerably smaller than the 0.7 micron pixels found on its 43.7 megapixel camera. Isocell Slim GH1 sensor released in 2019. “The new 0.64 μm Isocell JN1 will be able to equip tomorrow’s sleekest smartphones with ultra-high-resolution mobile photographs,” said Samsung Electronics executive vice president Duckhyun Chang.

The small size of the sensor will be useful for multi-camera setups, allowing smartphone designers to use the sensor for front, ultra-wide, telephoto, or standard cameras, depending on the configuration and resolution required. It will also reduce the thickness of the camera modules by around 10%, Samsung said.

The problem with tiny pixels is that they can’t collect as much light as larger pixels. So, for low-light shots, the sensor combines four pixels into one, quadrupling the light while reducing the sensor’s resolution to 12.5 megapixels. In addition to that, it uses the new Samsung Isocell 2.0 technology that replaces the metal barriers between color filters with a material that reduces light loss, increasing sensitivity up to 16%.

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