In recent years, mobile phones have made rapid progress in image capability. Through the relay and cooperation of multiple cameras, some flagship mobile phones have been able to achieve full coverage of commonly used shooting focus segments. Huawei's P40 Pro+this year has developed the ability of 10 times periscope optical zoom. In addition to the optimization of image quality by calculation, mobile phones have been able to replace some card machines.

However, the mobile phone is still largely limited by the thickness control of the body, which limits the space for further improvement of the image capability. For example, the image quality of the optical zoom of the mobile phone is still difficult to compare with the professional SLR and micro single camera.

Huawei may not be satisfied with this. Recently, a patent application submitted by Huawei to the European Union Intellectual Property Office (EUIPO) was disclosed. This patent shows that Huawei is trying to improve the imaging quality of mobile phones by connecting external lenses to the rear camera module of mobile phones.

This mobile phone in the patent drawing has a huge camera module, which occupies a large space in the upper half of the mobile phone. There is a bayonet that can be connected to the external lens, which can meet the needs of more professional shooting by connecting the lens of various focal sections. This practice is quite similar to the current interchangeable lens SLR and micro single camera.

However, many patents applied by mobile phone manufacturers often do not end up in mass production products. It remains to be seen how Huawei's mobile phone image will develop in the future.
