Samsung has been struggling to provide a superior camera experience in its smartphone models. The differences between the current Samsung cameras and the Nokia PureView technology are quite obvious. To offer better products, Samsung has developed ISOCELL – the new image sensors for premium devices.
Through a better control over the absorption of electrons, ISOCELL will provide an increased sensitivity, thus leading to better images in low-light condition – an area where Nokia domination is striking. The ISOCELL technology is a bit complicated, so we will try to make the matter a bit simple. ISOCELL will put a barrier between each pixel, isolating it. Through this isolation, the electrical crosstalk will be reduced and the micro lenses will collect and absorb more photons. The technology will allow Samsung to use much thinner camera modules, keeping at least the same quality of the images. The older BSI technology was pretty limited in terms of low light capabilities. You can see the difference between BSI and ISOCELL on the picture below:
Compared with BSI, the new image sensors will have an increased light absorption by 30%, a better color reproduction, sharpness and rightness, as well as a better dynamic range. The first image sensor to feature this new technology will be S5K4H5YB. It will be an 8 MP sensor with a 1.12 um pixel. According to the information, we should see the ISOCELL image sensor technology in the next Samsung high-end device in Q4 2013 and it could be the Galaxy S5.
ISOCELL is expected to significantly improve the image quality of both smartphones and tablets. With ISOCELL, Samsung shows that it is the most innovative company on the mobile market, and that’s why the Koreans are market leaders.
