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

Samsung is once again expanding the boundaries of pixels with its latest smartphone camera sensor. The Isocell JN1 holds 50 megapixels in a small 1 / 2.76-inch format for a pixel size of just 0.64 micrometers. That’s significantly less than the 0.7 micrometer pixels found in its 43.7-megapixel slim Isocell Slim GH1 sensor, released in 2019. “The new 0.64 μm Isocell JN1 will be able to equip the most elegant smartphones of tomorrow with ultra – high resolution mobile photos, “Samsung said. Vice President of Electronics, Duckhyun Chang.

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

0 percent, Samsung said.

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

The new sensor also includes Samsung’s “dual super PD” (phase detection) autofocus with twice the pixel density for phase detection, improving AF efficiency in low light. 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.
