Samsung is currently manufacturing the ISOCELL series of CMOS sensors that cover a variety of products ranging from 10MP to 100MP, of which 108 million pixel HM1 and HM2 sensors are used by several smartphones. Now, as per the latest info, the company officially unveiled the ISOCELL 2.0 technology, representing a further step in the manufacture of mobile phone CMOS sensors.
Back in 2013, Samsung introduced the ISOCELL technology for the first time that sets up a physical shielding layer between pixels. Compared with traditional BSI structure pixels, crosstalk is reduced by 30%, and the amount of light is increased by 20%, ensuring image quality. And, the ISOCELL technology has come to the 2.0 era, there are two key improvements that can further increase the amount of light.
However, the first technology uses new materials to replace the metal shielding layer between the previous pixels, which reflects a higher amount of light, reduces brightness loss, and improves the sensitivity of the sensor, and reduces noise.
On the other hand, the second technology adds a new shielding layer between the color filters to further improve the light reflectivity, while reducing the crosstalk between adjacent pixels of different colors. It can also greatly increase the amount of light entering the edge pixels of the sensor and reduce the vignetting phenomenon.
As per the demo photos released by Samsung, the schematic diagram shows that Samsung’s ISOCELL 2.0 technology still uses the traditional Bayer array. Moreover, the sensor using the new technology has a very fine shooting effect in dark light, with a rich dynamic range, natural colors, and high resolution.
Apart from this, Samsung launched a 50-megapixel GN2 sensor on February 23, 2021. The latest ISOCELL GN2 measures 1/1.12 inches, supports ISO Pro and Dual Pixel Pro (dual pixel enhancement) technology and can record 8K video or 4K 120fps video. Several reports suggest that Xiaomi’s upcoming Mi 11 Pro and Mi 11 Ultra will be released first and will monopolize the sensor in the short term.
