Samsung: New 50 Megapixel Sensor Wants to Improve Cheap Smartphones

Samsung is pushing the boundaries again when it comes to pixel sizes with its latest smartphone camera sensor. The Isocell JN1 holds 50 megapixels in a tiny 1/2.76-inch format for a pixel size of just 0.64 micrometers.

That’s considerably smaller than the 0.7 micrometer pixels seen on its 43.7 megapixel Isocell Slim GH1 sensor released in 2019. “The new 0.64 μm Isocell JN1 will be able to outfit the most stylish smartphones with photos of ultra-high resolution mobile phones,” said Executive Vice President of Electronics at Samsung, Duckhyun Chang.

The small-sized sensor will come in handy for multi-camera setups, allowing smartphone designers to use the sensor for front-facing, ultra-wide, telephoto or standard camera depending on the configuration and resolution required. It will also reduce the thickness of the camera modules by about 10%, Samsung said.

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

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