When Huawei P30 Pro was launched, one of the main highlights of the device was the 50X Optical Zoom lens it features. Huawei even shared camera samples of the moon reportedly shot using the P30 Pro’s camera. Soon after, moon capture began to trend with other OEMs also claiming their device can capture the moon as well. 
Turns out the technology at play on the P30 Pro’s Quad camera setup is a recently patented one by Huawei. A recent announcement by the State Intellectual Property Office indicates that Hauwei has patented a process called “a method and electronic device for shooting the moon.” The patent application number is 201910134047.X and the application was made on February 22, 2019.

The patent page shows that the technology provides a solution for shooting the moon and the camera setup to achieve this. The camera automatically recognizes the moon in the preview interface and enters the moon shooting mode after recognizing the moon. Thus, the lens is automatically focused on the moon and as such display a clear outline of the moon image in the preview interface.
The sketches accompanying the patent shows that during operation, a multi-frame moon image with clear contours under different exposures is collected. The acquired multi-frame images are processed differently to obtain photos of a clear and bright background including a clear and beautiful moon.
According to Huawei, this method can capture a vivid, crystal-clear moon in normal shooting mode or even when used by non-professional users. This will surely improve the user’s shooting experience. We must add that Huawei seems to be increasing the gap between its flagships’ cameras and those of rivals Huawei currently has the best phone cameras around. The P30 Pro and other Huawei flagship models have consistently maintained the lead atop DXOMark’s phone camera ranking.
