Samsung explains some of the key technologies behind its 108MP ISOCELL Bright HMX image sensorIN August this year, Samsung announced the 108MP ISOCELL Bright HMX image sensor for mobiles and now it is shedding some light on four key technologies it incorporates. With a pixel size of 0.8μm, this sensor can capture images of up to 185 million pixels. This allows you to preserve sharpness even when zooming in on a photo or crop out only what you need. In addition, the sensor expresses textures and colours more clearly in bright environments and absorbs more light in dark environments to make professional-level photographs.

The 108MP ISOCELL Bright HMX incorporates the ISOCELL Plus technology as well. It creates an innovative new material barrier between each pixel, minimizing light loss between pixels and preventing colour bleeding. Compared to previous Back Side Illumination (BSI) sensors, where image quality has degraded due to cross-pixel interference, cross-pixel performance is much better with smaller pixels. In addition, the sensor features Super Phase Detection autofocus which is very fast in autofocusing and helps to capture the subject more clearly even in low light conditions.

Secondly, the 108MP ISOCELL Bright HMX sensor uses the Smart ISO technology which allows it to operate in low-ISO and high-ISO mode. This makes it possible to take clear pictures in very dark environments without disturbing noise. Thirdly, it also uses Tetracell technology, which helps to take brighter pictures in dark environments. Smaller pixels can achieve higher resolutions on smaller sensors, but their ability to absorb light decreases, making it difficult to take bright, clear pictures in dark environments. Tetracell technology relocates pixels according to the light environment and uses four small pixels as if they were one large pixel to increase light absorption. Four 0.8μm pixels are converted to 1.6μm pixels, making the best use of limited light for high-quality images.

Currently, the only three official smartphones that pack the 108MP ISOCELL Bright HMX sensor dubbed Samsung S5KHMX are the following:
