Samsung has been working on its ISOCELL tech for a while now and the new camera technology is ready for primetime – it's used in the main camera of the Samsung Galaxy S5, which is bound to sell in the tens of millions.
What's ISOCELL anyway? It turns out, individual pixels are in actual cells.
Barriers between the pixels reduce the crosstalk between them by 30%, which reduces noise in low-light conditions. An added advantage of the cells is that they improve on the back-side illumination by growing each pixel's light-collecting capacity by 30%, which enhances the dynamic range.
Samsung also claims that the ISOCELL sensors are thinner than traditional BSI sensors, making them more suitable for thin superphones. Watch the video below for a better explanation of how ISOCELL works.
We'll certainly take a few low-light snaps when we get a Samsung Galaxy S5 review unit. It's worth noting that it has a relatively large 1/2.6" sensor - close to the 1/2.5" sensor Nokia uses for the Lumia 1520 and Icon.
