Samsung unveiled the ISOCELL Bright HMX in August, which is the industry's first mobile image sensor to exceed 100 million pixels and to feature a larger 1/1.33-inch size. Not much was known about the technologies behind the sensor until now. 

One of the key components underpinning the ISOCELL Bright HMX is Samsung's ISOCELL Plus technology which is an advanced pixel isolation technology that minimize optical loss through the use of an innovative new material for the physical barrier between pixels, and prevent each 0.8μm pixel from being contaminated by the colours of the ones adjacent to it. This allows the photodiode to absorb more light and result in superb pixel performance, even with smaller pixel sizes. 

Samsung also incorporated Smart-ISO technology comprising of one low and one high amplification into the ISOCELL Bright HMX, which allows the sensor to intelligently select amplification levels according to how the scene is lit, optimizes light-to-electrical signal conversion and making it more versatile across different lighting conditions. 

Samsung's Tetracell technology aims to address the age-old question in photography of how best to capture brighter photos in low-light conditions with small pixels. Thanks to Tetracell technology, the ISOCELL Bright HMX sensor has an advanced algorithm to rearrange the pixels according to lighting condition, merge clusters of four pixels into single pixels and allow 0.8μm pixels to be transformed into 1.6μm ones. The end result is incredibly high 27MP resolution for great low-light photography. 

There is also phase detection autofocus enabled by Super-PD technology to quickly calculate how far away an object is and automatically optimize focus for the shot. This enables the ISOCELL Bright HMX to capture clear photos with precise focus of both still and moving objects, even in low-light conditions.

The first device to be equipped with the ISOCELL Bright HMX is the Xiaomi Mi Note10, which we managed to get hold of an export set and took for a test run. The upcoming Galaxy S11 series and Galaxy Fold clamshell device are expected to sport the ISOCELL Bright HMX sensor or a variant of it.
