Taking a significant shot at standalone cameras, Samsung Electronics has announced the 108 megapixel (Mp) ISOCELL Bright HMX – the first mobile image sensor in the industry to go beyond 100 million pixels.

The ISOCELL Bright HMX is a one-of-a-kind mobile image sensor and is the result of close collaboration between Xiaomi and Samsung. With this latest addition to the family of ISOCELL Bright HMX image sensors, Samsung will expand its 0.8μm image sensor offerings from its recently announced ultra-high 64Mp to 108Mp, a resolution equivalent to that of a high-end DSLR camera.

The ISOCELL Bright HMX uses over 100 million effective pixels to produce extremely sharp photographs rich in detail. Further the sensor produces exceptional photos even in extreme lighting conditions, a key issue for many smartphone manufacturers.

Being the first mobile image sensor to adopt a large 1/1.33-inch size, the HMX can absorb more light in low-lit settings than smaller sensors and its pixel-merging Tetracell technology allows the sensor to imitate big-pixel sensors, producing brighter 27 Mp images.

In bright environments, the Smart-ISO, a mechanism that intelligently selects the level of amplifier gains according to the illumination of the environment for optimal light-to-electric signal conversion, switches to a low ISO to improve pixel saturation and produce vivid photographs. The mechanism uses a high ISO in darker settings that helps reduce noise, resulting in clearer pictures. For advanced filming, the HMX supports video recording without losses in field-of-view at resolutions up to 6K (6016 x 3384) 30-frames-per-second (fps).
