Samsung recently unveiled the Galaxy S20 series and the headliner of the flagships is the Galaxy S20 Ultra. It features a 108MP wide-angle camera, which is an improved version of the sensor previously seen in the Xiaomi Mi Note 10. The South Korean giant has now detailed its 108MP ISOCELL Bright HM1 sensor which features the company’s ‘Nonacell Technology’.

In addition to Nonacell Technology, the 108MP ISOCELL Bright HM1 unit also uses Smart-ISO tech to deliver high-resolution images in all kinds of lighting. It’s a 1/1.3-inch sensor with 0.8μm pixels and F/1.8 aperture, which should allow it to capture sufficient amounts of light. However, compared to phones with bigger 1.4μm pixels, noise can potentially be a concern. That’s where Samsung’s new and improved pixel binning technology that it calls Nonacell comes in, which uses a three-by-three array to replicate a 2.4μm pixel to increase light absorption.
