Samsung expanded the proposal of ISOCELL sensors for smartphone cameras with the new ISOCELL JN1 model. On this occasion, the South Korean giant held an entire online presentation (very unusual). It is a 1 / 2.76-inch, 50MP (8160x 6144) sensor with only 0.64μm pixels, an industry record. The novelty is about 10% more compact than the previous generation, which will reduce the protruding cameras of modern smartphones.

The previous record also belonged to Samsung’s solution – the 2019 44MP ISOCELL Slim GH1 with 0.7μm pixels.

The second key feature of the new ISOCELL JN1 is support for the second generation of ISOCELL 2.0 technology with a 16% improvement in light sensitivity.

Like previous sensor models, ISOCELL JN1 supports Tetracell binning technology (charge summation from adjacent matrix pixels), compensating for the small size of the photosensitive element. Adjacent pixels are grouped into groups of four to capture more light in low light conditions. In ISOCELL JN1, in low light, pixels are increased to 1.28 microns, while the image resolution is reduced to 12.5 megapixels.

It also claims support for improved phase detection autofocus Double Super PDAF (retains the same level of performance at 60% reduced light level) and Smart-ISO technology for automatically selecting the “correct” light sensitivity value depending on the environment.

In terms of video shooting capabilities, 4K @ 60 fps and FHD @ 240 fps are supported.

Samsung has already started mass production of ISOCELL JN1 sensors, so the first smartphones with them will probably not take long.
