Apple is exploring a way to connect images from multiple iPhone cameras and selectively control all of those devices at the same time for 360-degree shooting.
Apple continues to explore periscope cameras for the next generation of iPhones. So the latest patent application shows that it aims to use multiple cameras on multiple devices.
This system of generating continuous images from different image sources involves the synchronization of several iPhones. Of course, after that, they will combine images on the same iPhone.
"A photographer, videographer, or other individual may wish to take pictures using multiple imaging devices and combine the images captured by each of the individual devices into one continuous image."
The problem of using multiple devices can simply mean using everyone's camera in the group. However, Apple's patent application also describes how to actually install multiple iPhone options in a way that maximizes 360-degree coverage and minimizes overlap.
Apple describes this physical bracket as an "imaging unit structure." He also stated that his goal is to maintain a fixed camera position relative to other cameras. The idea is that these iPhones or other devices will be "located radially around the central axis of the capture unit."
The purpose of this design is that each chamber should "have an angle of at least 30 degrees with radiation away from the central axis", and they would overlap on the central axis. In general, they "constitute a 360-degree field of vision."
If all the devices have the same iPhone model, this structure means that the image quality produced by each camera is the same. This will make stitching images easier. But Apple noted that the system cannot assume that everyone has the same device.
What are the challenges of this 360-degree shooting technology?
One of the factors that affects the overall image quality is the image resolution. This may be limited by the size and configuration of the image sensor.
Therefore, while "some devices may allow you to capture high-resolution images in a standard format," other devices do not. The difference is not only in resolution. For example, a perfect image FoV (eg 360 degrees) may exceed the FoV of the lens of some devices.
Therefore, most of Apple's patent applications relate to a way to capture large, high-resolution images. And then how to compare and merge the overlapping images to form a single, continuous image.
The purpose of this is to make this combined image represent a single 360-degree lens. It is impossible to distinguish the connection there. For most photos, especially outdoors, changing light means it's best to shoot each part at once to create such a unified image.
So, while the patent application remains as broad as possible, Apple suggests that multiple iPhones can be connected via local Wi-Fi. Regardless of how to connect multiple iPhones. The idea is that one person can run all the cameras at the same time. Apple also offered a way to use the iPad to control all the devices.
