Samsung Galaxy S9 Release Date Could Include This Newly Announced ISOCELL Sensor

As Apple, Samsung and (perhaps, surprisingly) Google battle to claim the top spot in smartphone imaging, we've been left with lenses jutting out of the device, or in the case of the Note 8, a thicker phone.

The South Korean company's new image sensors are catering to demands for "sleeker smartphones" with "high resolution image sensors in small chip packages".

This image of Samsung Electronics Co.'s ISOCELL Fast 2L9 image sensor was released by the company October 11, 2017.

The two new ISOCELL image sensors: 1.28-micron 12-megapixel ISOCELL Fast 2L9 with Dual Pixel technology, and ultra-small 24-megapixel ISOCELL Slim 2X7 with Tetracell technology are targeted at smartphones available across different price categories, and with slimmer profile. Samsung promises this is all possible in low light too, vowing that it'll keep your next (presumably Galaxy-branded) smartphone bump-free, while also delivering "bokeh" depth of focus effects with just a single lens. Each pixel contains two photodiodes instead of one for better object detection and tracking. It has a pixel size of 0.9 micrometers, which Samsung said is the first in the industry to be smaller than 1 micrometer. With 12 million focus detecting pixels, the sensor is able to quickly focus on small still objects as well as 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.

In addition, the small 0.9μm pixel size enables a 24Mp image sensor to be fitted in a thinner camera module, allowing premium smartphones to offer high-resolution cameras in a very slim and elegant design. Tetracell applies one colour filter per four pixels, allowing brighter pictures in dark environments, as well as a re-mosaic algorithm that allows more accurate pictures in bright environments. No, this isn't a dual sensor. Back in 2012, Sony announced it would focus on three major sectors - games, mobile and image sensors - and posted record-high quarterly profits in the first fiscal quarter that ended in June this year, on the back of robust image sensor sales.
