Chinese smartphone maker Xiaomi on Wednesday showed off its first 64MP smartphone imaging technology at a global event in Beijing, thus making it the first handset player to exhibit the technology. The company also teased a 108MP sensor at the end of the event.

The technology was showcased in the presence of Bin Lin, President and Co-founder of Xiaomi and Jesuk Lee, Vice President, Head of Sensor Design for Samsung Electronics.

Powered by Samsung's GW1 64MP sensor, the 64MP smartphone technology will first come with a Redmi smartphone in India in the fourth quarter (Q4) of 2019.

"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 dark-light environments to achieve the best signal-to-noise ratio for the entire scene," the company said in a statement.

According to the company, the GW1 sensor uses ISOCELL Plus technology to create a pixel-to-pixel barrier to reduce light interference between pixels and consequently improve colour reproduction.

The GW1 outputs 64MP photos with a resolution of 9248x6936 pixels and comes with support for real-time hardware-supported high dynamic range (HDR) of up to 100-decibels (dB) that provides richer hues.

With the GW1, Samsung has Sony in its crosshairs. Xiaomi has relied on the Japanese electronics major so far to make its camera sensors. Its bestselling smartphone series, the Redmi Note 7, employs Sony's popular 48MP IMX586 sensor. Interestingly, the same Sony sensor has also been fitted in the OnePlus 7 Pro — a premium flagship that is priced more than four times the price of a base Redmi Note 7S.

Another Chinese handset maker, Realme, owned by the BBK Corporation, is also set to launch a 64MP camera phone using the same Samsung sensor. Realme CEO Madhav Sheth recently changed his Twitter name to Madhav '5' Quad. There are speculations of the new smartphone being named the Realme 5 (the predecessor of this is currently called Realme 3) as Chinese consider the number four inauspicious. Realme has previously posted the camera samples of the smartphone.

Realme's current flagship, the Realme X, also uses the 48MP Sony IMX586 sensor.

With details about Samsung's 64MP sensor out in the open, it's now the question of who'll launch it first.
