They are named Samsung ISOCELL HP1 and ISOCELL GN5 respectively
Samsung just announced two new mobile CMOS sensors called the HP1 and GN5. Guess how much megapixels the HP1 has?
While Samsung is the first one to make a 108mp sensor, the company is further stepping away from the limits and just said “screw it, here’s a 200mp sensor” still not close to the human eye resolution though. The other is a flagship-grade 50mp sensor with enhanced light sensibility.
Samsung ISOCELL HP1
You may have guessed it but this is the sensor with 200mp resolution! This makes a 48mp sensor look like a 5mp sensor by comparison. This sensor has 0.64µm pixels and the company has claimed that, despite its small size, it can capture a bright enough image even with little to no light. Normally, to achieve getting the brightest out of your image, the lens and the sensor should be big and wide enough and the aperture should also have large values so it can capture enough light. The larger the opening of the lens, the more light can enter. The main purpose of having a ridiculously large megapixel size is to reduce image deterioration when zooming in. This is especially useful in zoom cameras or telephoto cameras where they are used to capture images from far away, similar to a telescope.
The HP1 also features Samsung’s “ChameleonCell” pixel-binning technology. This pixel-binning tech uses a two-by-two, four-by-four or full-sized pixel layout depending on the environment and lighting conditions. Samsung says that it can take a 12.5mp image with a large 2.56µm pixel size and merge them into 16 different pixels, this pixel-binning tech can make us of the large micron pixel size in order to capture light, which is what happened with the other large MP camera sensors like the Samsung HM1 and the Sony IMX 686 sensors.
It can record 8K videos at 30fps. It does this by merging four neighboring pixels and scale them down to 50mp in resolution, eliminating the need for cropping or scaling for the full image resolution.
Samsung ISOCELL GN5
Described by Samsung as “the industry’s first 1.0μm image sensor to integrate Dual Pixel Pro, an all-directional autofocusing technology, that can substantially boost autofocusing capabilities.” The main selling point of this sensor is the aforementioned Dual Pixel Pro autofocusing tech that was also created by Samsung.
This sensor has 50mp of resolution. The way this sensor works is that Samsung has installed two photodiodes within each 1.0µm pixel size vertically or horizontally so that machine learning can identify a pattern in each and every direction of the image. Samsung said that this sensor has 1 million phase-detecting multi-directional photodiodes that cover every area of the sensor ensuring that images remain sharp and high quality regardless of lighting conditions. This also allows for near-instantaneous autofocus capture.
This image sensor also uses Samsung’s proprietary pixel technology called Dual Pixel based on a Front Deep Trench Isolation (FDTI) tech, a technology that prevents electric current leakage on CMOS sensors. According to Samsung FDTI allows each photodiode to absorb and carry more light information and decreasing crosstalk and smudges within the pixel.
Both sensors are now available for smartphone manufacturers to use.
