When a smartphone camera starts boasting more and more pixels, they also start to become bigger and bigger. Just as with a processor, the challenge for imaging sensors is to cram photos of small surfaces without increasing the size of the surface. That is the achievement that Samsung has bragged with new JN1 Isocell which is able to cram 50 million pixels in the size of a 1/2.56 inch format sensor. Whether it is able to take better quality or similar photos such as Samsung 50MP sensors larger, still have to be tested.
There are several analogies between problems faced by sensors and imaging processors when cramming more photodiodes or resistors in the same amount of space or smaller. For digital camera sensors, it means some mild cross between the diode, reducing the quality of the image produced. Samsung discusses this with the next ISOCELL 2.0 gene technology which also increases the amount of light collected by the sensor.
The new technology will be very important in the success of the new Isocell Sensor JN1 CMOS because of its use of 0.64 μm-pixels (micropixels). Cross-talk is even more likely with such small pixels, but also the possibility of decreasing light absorption, where Isocell 2.0 is entered. Samsung also boasts Smart ISO sensor features, shifting between low or high ISO levels depending on brightness settings.
In addition, Isocell JN1 is also equipped with a new Samsung Super PD that uses an oval micro lens to increase the phase-detect phase focus. This sensor is capable of recording 4K at 60 fps but also 240fps is slow-mo but only at FHD resolution. The sensor utilizes four-to-one Tetrapixel sticks to shoot bright 12.5MP images even in low light, effectively changing 0.64 micropixels into a 12.5MP micropixel sensor.
Samsung said that Isocell JN1 is currently in mass production, so the cellphone that bears the sensor should not be far behind. Sensor 1/2,76 inches compatible with 1 / 2.8 inch products so that the sensor can be used almost in any function, from ultra-width to telephoto cameras until the camera is facing a high quality front.
