Samsung said publicly on Tuesday that it has begun delivering a brand new mobile image sensor, ISOCELL GN1, to its customers.

The ISOCELL GN1 is a 1.2μm 50MP image sensor with a sensor size of 1/1.3 inches. Samsung said in a statement that the sensor is the first image sensor to support both Dual Pixel and Tetracell technologies.

The GN1 sensor is comparable to the IMX700 sensor released by Sony in February. Samsung ISOCELL GN1 supports 100 million phase detection autofocus (PDAF), bringing a first-class autofocus experience. In terms of low-light photography, GN1 uses Tetracell technology to combine four pixel signals into one, and at the same time double the pixel size of the image sensor to 2.4μm, achieving a four-fold increase in photosensitivity.

Samsung officially stated that ISOCELL GN1 has started mass production this month.
