Samsung Announced 108MP ISOCELL Bright HM1 CMOS

South Korean electronics manufacturer Samsung has launched a new generation of 100MP image sensors the ISOCELL Bright HM1 for Samsung’s latest S20 Ultra smartphone. The new generation of sensors improves the pixel integration technology. It synthesizes 2.4μm large pixels through nine adjacent pixels to increase the amount of incoming light.


Samsung Electronics calls the ISOCELL Bright HM1 ‘the new generation of 108M pixel image sensor’, which can make the picture brighter under low light conditions.

The HM1 uses a new generation of Nonacell technology, which is a pixel merging technology. As said, it can synthesize nine adjacent 0.8μm pixels to simulate a large 2.4μm pixel to improve screen brightness. In 2017, Samsung launched Tetracell technology, which supports the integration of four adjacent pixels. Nonacell is an enhanced version of Tetracell. Previously, the HMX sensor used by Xiaomi CC9 Pro supported four pixels in one and was able to synthesize 1.6μm large pixels.

Samsung Electronics said that as the number of neighboring pixels increases (now nine-in-one), color interference will also increase. So pixel consolidation is more challenging. However, Samsung uses ISOCELL Plus technology, which replaces the metal barrier with new material to reduce interference and minimize light loss and reflection.

In order to take good photos in any light, the ISOCELL Bright HM1 also adds several pixel technologies. Smart-ISO technology can intelligently adjust ISO. High ISO is used in a low light environment, and low ISO is used in brighter environment to control saturation. Real-time HDR technology can optimize exposure in complex environments. And it feels similar to Apple’s Smart HDR. In addition, the HM1 supports EIS (Electronic Image Stabilization) and Super-PD phase detection technology to achieve fast autofocus.

Also, the HM1 supports 3x lossless zoom. And 108MP is enough to generate 3x zoom photos at 12Mp resolution.

In terms of other hardware, the HM1 is 1/1.33 inches in size and has 108 million 0.8 μm pixels. These two points are the same as the previous HMX used by Xiaomi CC9 Pro.

Samsung Electronics said that the ISOCELL Bright HM1 is currently in mass production.
