Questions about changes in the focal length of the iPhone 16 camera and misalignment of the picture

Switched from SE2 to 16, single camera to dual camera. Today, I found that when switching focusing distance, the picture is out of alignment. Is this a common problem with multiple cameras, a common problem with iPhone16, or a problem with my device?

Anonymous5871 Mar 8, 2025Because these are two cameras, and the positions of the two cameras are destined to be different. So this problem is inevitably unsolvable. It doesn't work if Newton comes, 🐶 I'm afraid the two cameras can be located in the same position, and they won't switch seamlessly because of different focal length and other information, right?

Anonymous6095 Mar 8, 2025It may not be completely unsolvable, but the cost will be very high. This is the solution I came up with 1. Dynamic optical module (refer to revolver), directly and physically change the position of the lens to align it 2. Liquid lens! Since the position of multiple lenses is different, only one lens is used, and the physical curvature is changed by voltage to achieve single-module multi-focal length The above requires physically changing the lens module solution, which may not be able to be done in a short time, but in fact, similar problems also occur on vr headsets. That is, when perspective is achieved, the lens position cannot be on the eye, so the imaging will also be deviated., then the solution is: computational photography! 3D Scene Reprojection! Fast forward to directly let users customize the virtual lens position and design a UI that dynamically adjusts the focal plane

Anonymous861 Mar 8, 2025The two lenses are not in the same position, and there will be the same problem no matter how far away they are, but you can't see the difference in viewing angles between the two lenses after a long distance. It's the same reason as two human eyes. Unless it's a sensor + physical zoom lens. Otherwise, it's useless if Newton comes.

Some Android flagships have too large camera sensors, resulting in too large distance between lenses. This problem will become more serious. Name a telescopic lens phone

Anonymous1096 Mar 9, 2025Parallax in close-range focusing is indeed an inevitable optical problem, because it is not true optical zoom, which is like putting your hands in front of your eyes and simulating it. However, the multi-camera synergy of the 16PM generation has indeed regressed (or the bug of iOS18). The lens position of the multiple generations of Max models I used has not changed, but the color white balance consistency and zoom smoothness of the 16PM multi-camera exposure are not as good as those of the previous generation.
