Samsung announces new 50MP ISOCELL GN2 camera sensor with Dual Pixel Pro


Samsung has just announced its new 50MP camera sensor, called ISOCELL GN2. It follows on from last year’s GN1 and comes with bigger pixels, better power consumption, and all new PDAF technology called Dual Pixel Pro.

The type size of the ISOCELL GN2 sensor is 1 / 1.12 ”, which is the largest in a smartphone and has 1.4 μm pixels for“ exceptionally detailed photographs at normal settings ”. Quality images in a low light environment are achieved with the well-known four-pixel clustering technology, simulating a larger pixel of 2.8 μm.

The new sensor also offers the ability to take 100 MP photos by rearranging the color pixels using a “smart re-mosaic algorithm,” as Samsung puts it. In reality, the 100 MP photos are three 50 MP layers in green, blue, and red, then layered, scaled, and merged to produce the high-resolution photograph.

The new sensor is also Samsung’s first to offer Dual Pixel Pro, the company’s most advanced PDAF solution. Instead of dividing all of the red, green, and blue pixels vertically, this time the green pixels are divided diagonally, so the top and bottom can read phase differences, as well as the left and right sides.

The result should be fast and accurate autofocus in difficult conditions such as a low-light environment or a fast moving object. It should also take into account previous limitations, such as detecting parallel or horizontal stripes, which means that now the ISOCELL GN2 and all future Dual Pixel Pro cameras will get focus lock even faster.

Other specs of the Samsung ISOCELL GN2 include Smart ISO Pro for creating instant HDR images with less motion artifacts and 1080p @ 480 fps or 4K @ 120 fps video recording. The company has confirmed that the sensor is already in mass production.
