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

Yordan, 23 February 2021

Samsung has just announced its new 50MP camera sensor, called ISOCELL GN2. It is a follow-up of last year’s GN1 and comes with bigger pixels, better energy consumption and the entirely new PDAF technology called Dual Pixel Pro.

The ISOCELL GN2 sensor's type size is 1/1.12”, which is the largest in a smartphone and has 1.4μm-sized pixels for “exceptionally detailed photographs in regular settings”. Quality images in a low-lit environment are done with the well-known four-pixel-binning technology, simulating a larger 2.8μm pixel.

The new sensor also offers the capability to take 100MP photos through re-arranging the color pixels using “an intelligent re-mosaic algorithm”, as Samsung puts it. In reality, the 100 MP photos are three 50 MP layers in Green, Blue, and Red, and then overlaid, upscaled and merged to produce the high-resolution photograph.

The new sensor is also Samsung’s first to bring Dual Pixel Pro - the company’s most advanced PDAF solution. Instead of splitting all the red, green, and blue pixels vertically, this time, the green pixels are split 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 low-light environment or fast-moving object. It should also address previous limitations, such as detecting parallel or horizontal stripes, meaning now the ISOCELL GN2 and all future Dual Pixel Pro cameras will obtain focus lock even faster.

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