BusinessWire, BusinessWire: Samsung introduces its next-generation 108MP sensor, ISOCELL Bright HM1 with a spectrum of light-enhancing technologies spanning from Nonacell and Smart-ISO to real-time HDR. The Bright HM1 can capture 8K videos at 24 fps.

The 1/1.33” format sensor with 0.8μm pixels ISOCELL Bright HM1 features Nonacell technology, which delivers brighter images in low-light settings. In 2017, Samsung introduced Tetracell, a pixel-binning technology with a special two-by-two array that merges four neighboring pixels to work as a single large pixel. Nonacell is an enhanced version of Tetracell with a three-by-three pixel structure. In the HM1, Nonacell merges nine neighboring 0.8μm pixels to mimic a large 2.4μm pixel, more than doubling Tetracell’s light absorption.

As the number of adjoined cells increase, so does color interference, making pixel-binning technologies more challenging, While such difficulties had limited Nonacell to a theory, the HM1 was able to realize the method by adopting Samsung’s ISOCELL Plus technology, which reduces crosstalk and minimizes optical loss as well as light reflection.

The HM1 supplements Nonacell with several other advanced pixel technologies. For example, the HM1’s Smart-ISO technology intelligently selects the optimal ISO. High ISOs are used in darker settings while low ISOs are better for brighter environments to control light saturation.

To capture meaningful moments in our lives, Samsung has been driving innovations in pixel and logic technologies that enable ISOCELL image sensors to take astounding photographs even when lighting conditions aren’t ideal,” said Yongin Park, EVP of the sensor business at Samsung. “By adopting Nonacell and Smart-ISO technologies, the 108Mp ISOCELL Bright HM1 helps take vivid high-resolution pictures across a wide range of lighting environments.

Samsung ISOCELL Bright HM1 is currently in mass production.
