Samsung Announces its next-generation 108-megapixel image sensor – Samsung ISOCELL Bright HM1

Samsung today announced its next-generation 108-megapixel (Mp) image sensor, Samsung ISOCELL Bright HM1. With a spectrum of light-enhancing technologies spanning from Nonacell and Smart-ISO to real-time HDR, ISOCELL Bright HM1 allows brighter and more detailed 108Mp photographs and crystal-clear 8K videos at 24 frames per second (fps), even under extreme lighting conditions.

At a 1/1.33” scale with 108-million 0.8μm pixels, Samsung  ISOCELL Bright HM1 features the industry’s first state-of-the-art 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.

For ultimate results under any lighting condition, the HM1 supplements Nonacell with several other advanced pixel technologies. For example, the HM1’s Smart-ISO technology produces vivid and vibrant images by intelligently selecting the optimal ISO. High ISOs are used in darker settings while low ISOs are better for brighter environments to control light saturation. For sharper results, the HM1 supports a gyro-based electronic image stabilization (EIS) and Super-PD, an advanced phase detection technology for fast and accurate auto-focus.

The HM1 allows users to preview and capture full shots and close-ups of the subject at up to 3x lossless zoom, preserving the quality of the image. This is made possible by the sensor directly converting the pixels using an embedded hardware IP, rather than having the task delegated to the mobile processor. With 108-million pixels, the sensor is also able to produce images up to 3x zoom at a 12Mp resolution without upscaling.
