Apple applies for new patent and is approved, future iPhone flash will also be able to autofocus

Nowadays, many smart phone manufacturers advertise the camera's night-shot ability, and the chance of using flash to assist in shooting is not high. The flash is often reduced to a flashlight of a mobile phone, which is convenient for users to find objects in dim environments. This situation is expected to change in the future, because Apple has obtained a patent earlier to improve the shortcomings of mobile phone flash and make it more practical.

At present, there are not many parameters that can be adjusted by the mobile phone flash. At most, it can only adjust the brightness, but the range of the fill light is fixed. As a result, there is light in the center part and the other places are quite dim, making the photo look very unnatural.

The patent filed by Apple is called "Light Source Module with Adjustable Focus". Simply put, it is to add a diffuser that can adjust the focal length to the flash. When shooting, it will move in accordance with the lens focal length to expand or reduce the fill light range, so that when shooting There will be more consistent fill light.

If Apple realizes the patent, in the future, when shooting with iPhone, turn on the flash, it will get the effect of auto focus adjustment similar to DSLR camera flash. However, Apple applies for many patents every year, and not all of them will be commercialized. Even if Apple decides to apply it to the iPhone, it is not known when it will be realized.
