Samsung's latest imaging sensors may rid smartphones of camera bumps

Likely ideal as a mid-range rear-facing camera sensor, it will enable features like bokeh effects and will apply improvements to quick focus and low light photography. Samsung's two new sensors were designed smaller but with high resolution, the company said.

Image sensors are chips that change visual imformation gathered through lenses into digital signals to be displayed on screen.

Before Samsung announced the Galaxy Note 8 and its first ever dual camera system, it prepared the road by launching its imaging sensors into a distinct and marketable brand of its own: Samsung ISOCELL. Samsung's recent announcement does not detail whether it's new camera sensors would include additional features for use with biometrics.

The ISOCELL Fast 2L9 and Slim 2X7 are created to be slim and offer good performance in low-light conditions.


The ISOCELL Slim 2X7 sensor, on the other hand, is being marketed as the first sensor in the industry to have the pixel size below 1.0 micron.

This image of Samsung Electronics Co.'s ISOCELL Fast 2L9 image sensor was released by the company October 11, 2017. The technology employs two photodiodes in each and every pixel of the sensor instead of only one.

"With 12 million focus detecting pixels, the sensor is able to not only quickly focus on small still objects, but also lock on and track moving objects without losing focus, even in low-light environments". The Slim 2X7 has a 24-megapixel configuration with Tetra Cell technology.

Talking about Tetracell technology, Samsung says that the tech allows the sensor to take brighter low-light images. "This enables consumers to use the same front camera to take photos in various lighting conditions", explains Samsung. Even with that tiny pixel size, this sensor can give smartphone cameras a high color fidelity, and allows those phones to cram in a 24 MP image sensor inside a thin casing. The world's No. 1 semiconductor by sales said in a conference call with analysts in April that the company would convert part of its DRAM production line in Hwaseong, Gyeonggi plant into one devoted to Cmos image sensor manufacturing.
