Samsung ISOCELL GN1 50 MP image sensor announced with faster auto

Samsung ISOCELL GN1 50 MP image sensor announced with faster auto”

As is the norm on high-end phone sensors nowadays, Samsung has applied some smart algorithms to the hardware as well, which it claims can match the detail and quality of photographs taken on a 100-megapixel sensor.

Well, we didn't have to wait long as the Korean giant has today announced its new 50MP ISOCELL GN1 sensor. The first is Samsung's Dual Pixel technology, where two light-converting photodiodes are packed into a single pixel: that means light can be captured from more angles, and should mean the subjects of your photos snap into focus sooner. Samsung employs every pixel in its sensor to act as the auto-focusing agent (two in one pixel), making it possible for the camera to focus on subjects nearly instantly.

The new ISOCELL GN1 is a 50MP sensor with 1.2μm pixel size, marginally smaller than the 1.22μm pixel size of Sony's 48MP IMX689 sensor. The company just unveiled its latest creation: a 50MP image sensor with bigger pixels, "DSLR-Level" autofocus performance, and better low-light chops. Sometimes it's not all about the megapixels (though Samsung has a 108 MP sensor too, as found in the Galaxy S20 Ultra).

The sensor has Tetracell technology for 4-in-1 pixel binning, while the in-house ISOCELL Plus technology is said to keep pixel cross-talk in check, minimize optical loss, and produce more detailed images. The image sensor's pixel size is doubled to 2.4μm while the light sensitivity is quadrupled, as per the blog post.

The adroit mix of high resolution and fast autofocus speed seems Samsung's strategy with the ISOCELL GN1.

Additionally, the ability to capture more light combined with the dual-pixel AF technology allows the sensor to process and capture objects quickly even in low-light environments. Other features include Real-time HDR, gyro-based image stabilization, 8K/30fps recording, and 400fps video at 1080p without autofocus and 240fps with autofocus support.

According to Yongin Park, executive vice president of sensor business at Samsung Electronics, the company has been at the forefront of offering high-performance image sensors.
