Samsung is expected to launch "Hexa²pixel" sensor with a resolution of 450MP
The term "Hexa²pixel" was trademarked by Samsung, which the paperwork describes as "image sensors for photographic devices." This was discovered by GalaxyClub initially, and now Ice Universe, a leakster, has posted about the trademark, hinting at the sensor's resolution.
According to the leaker, this sensor will be capable of 36-in-1 pixel binning (a group of 6x6 pixels combined into one), which is far greater than what Tetracell and Nonapixel are capable of (2x2 and 3x3, respectively). If we assume that the goal is 12MP image output (as was the case with the previous two), we may calculate the resolution. It comes out to 432MP; however, it may also be rounded to 450 MP. Regardless, it will more than double the resolution of Samsung's 200MP sensors, such as ISOCELL HP1 and HP3. It has a 1/1.22" (0.64 µm pixels) size.)
Both HP sensors feature “Tetra²pixel” color filters, which enable them to perform 4x4 and 2x2 pixel binning for 12MP and 50MP outputs, respectively. Given the name of the new sensor's "²," it will most likely have two output modes. 6x6 and 3x3 are possibilities. If so, it will be able to produce 12MP and 48MP resolution images, respectively. Binning would be required because even if the sensor is big enough, cramming that many pixels into a small area would make them seem insignificant.
Some leaks claimed that Samsung is working on sensors with resolutions as high as 600MP (with an enormous 1/0.57" optical format), so this Hexa²pixel sensor might represent just the beginning of what's to come in the next few years.
