Samsung has officially unveiled ISOCELL HP1 as the world's first 200-megapixel smartphone camera sensor. It is the highest megapixel resolution sensor that has been released for smartphones. There are a couple of technologies that help it achieve superior camera results. The team further announced ISOCELL GN5 which is a "super-slim" 50-megapixel sensor.
The ISOCELL HP1 is a 200-megapixel camera sensor with a native 0.64μm pixel size. It comes with ChameleonCell pixel-binning technology for improved low-light performance. The tech is able to adapt to the surrounding lighting environment and use a two-by-two, four-by-four, or full pixel layout accordingly.
Samsung says the technology merges 16 neighboring pixels to form a single big-sized pixel i.e. 2.56μm for offering better results in low-light conditions. It is capable of more light absorption and sensitivity, producing brighter and clearer photos indoors or in the evening. The camera works as a 12.5-megapixel sensor in such scenarios but when there is a bright-light outdoor environment, the sensor is 200-megapixels.
The sensor is capable of shooting 8K videos at 30 frames per second with minimum loss in the field of view. It works as a 50-megapixel sensor by merging four neighboring pixels. It helps in recording the video without the need for cropping or scaling down the image resolution.
The ISOCELL GN5 is a super-slim 50-megapixel smartphone camera sensor. It is so slim that the pixel size is just 1.0μm. There is support for Dual Pixel Pro autofocusing technology. It works by placing two photodiodes on either the horizontal or vertical side of the 1.0μm pixel. This results in one million phase-detecting multi-directional photodiodes providing complete sensor coverage for instantaneous autofocusing.
It offers 2x2 pixel binning for clicking better low-light shots at 12.5-megapixels. Another technology implemented in the sensor is called Front Deep Trench Isolation (FDTI). It enables each photodiode to absorb and hold more light information, improving the photodiodes’ full-well capacity (FWC) and decreasing crosstalk within the pixel.
