Adopting the company’s Nonacell and Smart-ISO technologies, the 1/1.33” image sensor packs 108-million 0.8μm pixels. Nonacell is an enhanced version of the Tetracell technology launched in 2017, 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 colour 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 dramatically reduces crosstalk and minimizes optical loss as well as light reflection.
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. In challenging mixed-light environments for photo-taking, the HM1’s real-time HDR technology optimizes exposures, producing more natural looking videos and still photographs.
By assigning the most appropriate exposure lengths to each pixel, the HM1 is able to capture scenes in multiple exposures simultaneously, generating HDR images in real-time for both preview and capture modes. 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.
What’s more, 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.
