Samsung unveils a 50MP sensor with the smallest pixels sized 0.64μm

Samsung introduced the smallest 0.64-micrometre (μm)-pixel image sensor, the 50MP Samsung Isocell JN1 for mobile photography. It comes equipped with technologies such as enhanced Isocell 2.0, Smart-ISO and Double Super PDAF.

The small-sized pixels on the new 50MP sensor enhance light sensitivity by around 16% and also bring improvement to phase detection. The latest addition to Samsung’s high-res image sensor lineup is in mass production, the company announced on Wednesday.

The sensor uses Samsung’s four-to-one pixel binning tech called Tetrapixel for low-light photography. It merges four adjacent 0.64μm-pixels into one big 1.28μm-pixel, which quadruples the light sensitivity for brighter 12.5MP photographs.

The new sensor features twice the density of pixels for phase detection, that allow same level of auto-focus performance even in 60% less light. It also comes with enhanced dynamic range as the sensor merges low ISO and high ISO settings to create the final image in mixed light settings. The tech is called Smart ISO.

“Samsung’s advanced pixel technologies have once again pushed boundaries with the utmost precision to develop an image sensor with the industry’s smallest pixel size, yet with powerful performance,” said Duckhyun Chang, executive VP of the sensor business at Samsung Electronics. “The new ISOCELL JN1 at 0.64μm will be able to equip tomorrow’s sleekest smartphones with ultra-high resolution mobile photographs.”
