Samsung claims the HM1 sensor is the first image sensor to use Nonacell technology, which is an enhanced version of Tetracell with a 3 x 3 pixel structure. In the HM1, Nonacell merges nine neighboring 0.8 μm pixels to mimic a large 2.4 μm pixel, more than doubling Tetracell’s light absorption.
The HM1 supplements Nonacell with several other pixel technologies that produce vivid and vibrant images by selecting the optimal ISO used in darker settings while low ISOs are better for brighter environments to control light saturation.
The HM1 image sensor allows users to preview and capture full shots and close-ups of the subject at up to three times lossless zoom by the sensor converting the pixels using an embedded hardware IP, rather than having the tasks delegated to the mobile processor. With 108 million pixels, the sensor is also able to produce images up to three times zoom at a 12 MP resolution without upscaling.
Additionally, the sensor supports gyro-based electronic image stabilization (EIS) and Super-PD, an advanced phase detection technology for fast and accurate auto-focus.
