"Combining 9 pixels into one to capture": Samsung Electronics unveils 108-megapixel image sensor HM1
Published2020.02.12 17:01Synthesizing 9 pixels into 1 to expand the light-receiving area
Enhanced zoom function, no loss in image quality even at 3x magnification
On the 12th, Samsung Electronics launched the next-generation mobile image sensor, 'ISOCELL Bright HM1'.
The ISOCELL Bright HM1 is a product that implements 108 million small pixels measuring 0.8㎛ (micrometers) in a 1/1.33-inch size and features 'Nonacell' technology, which provides good sensitivity, the degree to which the image sensor responds to light.
Nonacell is an image sensor technology that makes nine adjacent pixels function as one pixel, enabling brighter images in dark conditions and more detailed images in bright conditions depending on the shooting environment.
As the number of pixels to be merged increases, color interference between adjacent pixels becomes more sensitive, so while it is theoretically possible, it is not easy to implement in practice.
Samsung Electronics prevented interference, light loss, and scattering between adjacent pixels that can occur with the implementation of Nonacell by applying 'ISOCELL Plus,' a patented technology for creating separation membranes between pixels.

The ISOCELL Bright HM1, utilizing Nonacell technology, enables high-sensitivity shooting in dark environments by using small 0.8㎛ (micrometer) pixels as if they were large 2.4㎛ pixels. Compared to 'Tetracell,' which uses four pixels, it can capture more than twice as much light.
The preview function using enhanced image zoom is also noteworthy. With 108 megapixels, the ISOCELL Bright HM1 allows you to view the captured image without loss of quality even when zooming in on the subject up to 3 times (12 megapixels).
In addition, it is equipped with image sensor technologies such as Smart ISO, Real-time HDR (High Dynamic Range), and Electronic Image Stabilization (EIS), enabling clear shooting in various environments.
Not only image performance but also video performance has been enhanced. The ISOCELL Bright HM1 is capable of shooting video at 24 frames per second at a maximum resolution of 8K (7680x4320).
The ISOCELL Bright HM1 is currently in mass production and was installed in the Galaxy S20 Ultra unveiled on this day.
