Samsung’s GW1 64MP Sensor Powering Xiaomi's 64MP smartphone imaging

Xiaomi has announced its first 64MP smartphone imaging technology at a global event held in Beijing. Powered by Samsung’s GW1 64MP sensor, the 64MP smartphone technology will first appear on a Redmi smartphone in India in the Q4 of 2019.

Bin Lin, President and co-founder, Xiaomi, took to the stage to announce the 64MP imaging technology alongside Jesuk Lee, Vice President, Head of Sensor Design for Samsung Electronics. The GW1 sensor uses ISOCELL Plus technology to create a pixel-to-pixel barrier to reduce light interference between pixels and consequently improve color reproduction.

The GW1 features smart ISO supported by Dual Conversion Gain (DCG) technology, which intelligently adjusts the ISO sensitivity based on ambient light intensity. It uses low ISO in high-brightness environments, and high ISO in the dark-light environments to achieve the best signal-to-noise ratio for the entire scene.

The GW1 outputs 64MP photos with a resolution of 9248 x 6936 pixels. It comes with support for real-time hardware-supported high dynamic range (HDR) of up to 100-decibels (dB) that provides richer hues. Compared to the dynamic range of a conventional image sensor, which is at around 60dB (while that of the human eye is typically considered to be around 120dB), the GW1 strives to provide true-to-life imagery.

The technology will first appear on a Redmi smartphone in India in Q4 of 2019.
