Samsung Unveils Its New Flagship 200MP ISOCELL HP1, 50MP ISOCELL GN5 Mobile Image Sensors
Cameras are one of the most important aspects of smartphones these days, thus negating the need to carry around another camera. Until now, 100MP was the highest resolution a smartphone camera could handle, but Samsung has now introduced a 200MP image sensor. The company has announced a new line of smartphone camera sensors with higher resolution than any on the market. ISOCELL HP1 200 megapixels (MP) the image sensor has 0.64μm pixels. While the 50-megapixel ISOCELL GN5 uses all Dual Pixel Pro technology with two photodiodes in a single 1.0μm pixel.
Duckhyun Chang, executive vice president of sensor business at Samsung Electronics, said at the launch: “Samsung is pioneering ultra-fine pixel technologies that take high-resolution image sensors to the next level. With the barrier-breaking ISOCELL HP1 and the ultra-fast autofocus ISOCELL GN5, Samsung will continue to lead the trend in next-generation mobile imaging technology.”

The South Korean giant is expected to use the ISOCELL HP1 sensor on the upcoming Samsung Galaxy S22 Ultra, which is capable of supporting 200MP resolution.

It is based on the company’s latest 0.64μm pixels. The newly launched mobile image sensor is designed for low-light photography purposes as it features the all-new ChameleonCell technology. It is a pixel binning technology that uses a two-by-two, four-by-four, or full pixel layout depending on the environment.
In low-light situations, the ISOCELL HP1 reconstructs itself into a 12.5MP image sensor with large 2.56μm pixels by homogenizing 16 adjacent pixels at once. According to Samsung, the all-new 2.56μm pixel is capable of more light absorption and sensitivity, producing brighter and clearer photos indoors or at night.

In well-lit environments or outdoors, the 200 million pixel sensor can capture ultra-high resolution photos on mobile devices. In addition, Samsung’s ISOCELL HP1 is capable of recording 8K videos at 30 frames per second (fps) with minimal field of view loss. This sensor can also combine four adjacent pixels to bring the resolution down to 50MP or 8192 x 6144 for 8K (7680 x 4320) video capture without the need to crop or downscale the full frame resolution.
On the other hand, the 50MP ISOCELL GN5 is the industry’s first 1.0μm image sensor to feature Dual Pixel Pro technology. This technology is an omnidirectional autofocus technology that greatly expands the capabilities of autofocus. This technology places two photodiodes, the smallest in the industry, in each 1.0μm sensor pixel either horizontally or vertically to detect pattern changes in all directions.
Samsung’s ISOCELL GN5 autofocus is faster and produces sharper images in all lighting conditions. This mobile image sensor also uses Samsung’s proprietary pixel technology to apply Front Deep Trench Isolation (FDTI) to the Dual Pixel product. Without being affected by the microscopic size of the photodiode, FDTI allows each photodiode to absorb and store more light information, thereby improving the full photodiode capacity (FWC) and reducing pixel crosstalk.
