Your next iPhone could have swappable camera lenses, based on a patent application published last week.
The improved camera system would include a digital imaging subsystem and an optical-axis lens, covered by a removable back panel, a first for an Apple phone.
The patent app was first reported by AppleInsider.
The patent drawings depict an iPhone-like structure. New optical options would allow users to reconfigure or even replace the lens depending on the photo opportunity, a process more closely resembling high-end digital cameras with features like supplementary lenses and filters, optical zoom, and optical image stabilisation.
"As the quality of digital images that can be obtained with highly compact devices increases, there is increasing demand for sophisticated features," the application said.
Apple did not immediately respond to request for comment.
While a camera's digital imaging subsystem is usually encased within the device for protection, the company said in its patent that it would be "desirable to provide a structure for a compact device that allows the end user to reconfigure the optical arrangement of the device while retaining the benefits of assembling the device using a pre-assembled digital imaging subsystem."
In other words, the iDevice would allow users to open the back panel without disrupting the digital imaging subsystem to change the lens or take black and white photos at low light levels.
One embodiment of potential camera product is a close-up lens that reduces the minimum focal distance, allowing extreme macro photography. According to the patent application, Apple could also be working to include better shutter speeds, providing better control of image exposure. A panel with two lenses built-in at opposite ends isn't out of the question, judging by one of the patent's drawings. To swap from a telephoto lens to a different filter, just flip the panel upside down.
