Taking advantage of Fujifilm’s collaboration, Samsung has developed the new ISOCELL Plus technology, which can be used both in the smartphones and in digital cameras. To explain the advantages it is necessary to start from the foundations, ie from the types of sensors supplied with smartphones: FSI, with front lighting, and BSI, with backlighting.
The ISOCELL Plus technology, just like the previous one, uses BSI sensors thanks to which it is possible to capture more light for the same scene. The problem of the onset of photographic noise when the light instead of going on the single photodiode affected more than one at a time was reduced in 2013 with ISOCELL, isolating the photodiodes with a physical barrier and focusing the photons with a microlens.
With ISOCELL Plus from Samsung, a new material is used to make the metal grid that separates the pixels, which limits the absorption or reflection of light, a factor that mortifies the advantages of BSI backlit sensors.
With the collaboration of Fujifilm, in this way it was possible to increase the color fidelity and light sensitivity by 15%, thus allowing the use of smaller pixels for the same yield. And with more compact pixels you can push on the resolution.
