Samsung's 108-Megapixel ISOCELL Bright HM1 Sensor with Nonacell Technology Debuts with Flagship Galaxy S20 Ultra Smartphone
Samsung Electronics has introduced its next-generation 108-megapixel image sensor, Samsung ISOCELL Bright HM1. Using a range of light-enhancing technologies from Nonacell to Smart-ISO and real-time HDR, the new 108MP sensor produces brighter and more detailed stills and crystal-clear 8K videos at 24fps even under extreme lighting conditions.
HM1 108MP sensor: Nonacell, Smart-ISO, & Real-time HDR
Sized at 1/1.33", the 108MP sensor has a pixel pitch of a mere 0.8μm. Samsung builds on the Tetracell technology that it introduced in 2017, which merges four adjacent pixels to form a single large pixel, to improve low-light performance. Nonacell uses a three-by-three pixel structure, merging 9 adjacent 0.8μm pixels to mimic a single 2.4μm pixel, more than doubling Tetracell's light absorption.

As the number of adjoined cells increase, so does color interference, making pixel-binning more challenging. HM1 adopts Samsung’s ISOCELL Plus technology to reduce crosstalk and minimize optical loss as well as light reflection, making Nonacell a reality.
Beyond Nonacell, the HM1 sensor also incorporates several other advanced technologies: Smart-ISO and Real-time HDR adjusts ISO and HDR modes automatically to produce cleaner photos with higher dynamic range.
With 108 megapixels, the sensor supports up to 3x lossless zoom at 12MP without upscaling.

Galaxy S20 Ultra: The New Flagship
The 108MP ISOCELL Bright HM1 sensor debuts with Samsung's latest flagship smartphone, the Galaxy S20 Ultra. It features a total of five cameras, including a rear quad-camera setup.
Here, the 108MP sensor is paired with an f/1.8 lens with 79-degree angle of view (26mm full-frame equivalent) and phase-detect autofocus. It is complemented by an ultra-wide 12MP camera with f/2.2 lens at 120-degree angle of view (12mm full-frame equivalent), a telephoto 48MP camera with optical image stabilization, phase-detect autofocus, and a f/3.5 lens at 24-degree angle of view (100mm full-frame equivalent).
