Apple’s Periscope Lens Plans Stymied by Samsung Patent: Report

Apple is reportedly hoping to integrate a periscope camera lens system into its iPhones as soon as 2023, but a new report out of Korea alleges that the Silicon Valley giant may have run up against a problem: a Samsung patent.

As some background, “periscope” is the term used to describe a “folded” lens system that can squeeze greater zoom capabilities into the tiny camera arrays found in smartphones by redirecting light sideways through the body of the device via a sequence of lenses and mirrors or prisms. The design is deemed "periscope" because it mimics how a submarine periscope looks and works.

As PetaPixel has reported in the past, such technology is behind the Samsung Galaxy S21 Ultra’s 10x optical zoom, which is considerably more than the iPhone 12 Pro Max’s 2.5x zoom.

Apple has filed multiple patents for "folded" lens type periscope camera designs in the past, including one that was granted as recently as July and another from August that integrates optical image stabilization.

There are varying ways to construct a periscope lens especially when it comes to how a company moves the lens's barrel. According to a report from The Elec, Apple wants to use a ball actuator to move the lens barrel, which is in contrast to the spring actuator that it currently uses on its iPhones. Unfortunately for Apple, Samsung -- who has a technical lead on the technology over Apple -- holds that patent.

Samsung Electro-Mechanics

The Elec explains that Apple was planning to supply folded zoom camera modules from a long-time supplier for the company, LG InnoTek, which procured the ball actuators from Samsung Electro-Mechanics.

If Cupertino have chosen this route, it would have replaced its actuator partners Alps Electric and Mitsumi Electric with Samsung Electro-Mechanics.

Meanwhile, Apple reviewed Jahwa Electronics’ optical image stabilization module factory during the first half of the year.

OIS are conventionally integrated with autofocus actuator to form one module. The integrated module is Jahwa’s main product. Combining it with an image sensor and a board completes a camera module.

However, Jahwa co-developed the OIS technology with Samsung and Samsung Electro-Mechanics, raising concerns that it may not be able to supply them to Apple.

Faced with this issue, Apple will either have to change its entire design to avoid using the patented technology or will have to pay Samsung a fee to license the rights to the patent. Both are of course options for the tech giant, but it is likely not a choice the company was expecting to have to make.

Apple Granted ‘Periscope’ Compact Zoom Lens Patent

The United States Patent and Trademark Office has granted Apple a patent for a compact camera that uses a set of prisms to "fold" light and compress the amount of space needed for a telephoto lens. This type of lens is typically referred to as a "periscope" lens in smartphones.

As some background, “periscope” is the term used to describe a “folded” lens system that can squeeze greater zoom capabilities into the tiny camera arrays found in smartphones by redirecting light sideways through the body of the device via a sequence of lenses and mirrors or prisms. The concept has been used in other smartphones not made by Apple, like the Samsung Galaxy S21 Ultra’s 10x optical zoom.

Earlier this year, famed Apple expert Ming-Chi Kuo said that Apple was at least two years from implementing the technology in its devices, meaning it is highly likely that Apple users will be stuck with low-powered two to three times optical zoom for the next couple of years. Apple has filed multiple patents for a periscope-like lens system in the past, and today's latest is just another added to the stack. One of its patents was filed back in 2015, and yet no iPhone has yet to use the tech.

The patent, reported by Patently Apple and spotted by DPReview, describes a "folded" camera lens that may be used in small form factor cameras, like smartphones. It uses two light folding elements -- in this case, prisms -- and an independent lens system ocated beetween them that includes an aperture stop and lens elements with refactive power mounted in a lens barrel.

The prisms "fold" the optical axis for the camera and reduce the z-height of the system. Inside the stack are one or more refractive lens elements mounted in a lens barrel.

The stages by which the periscope system works.

Somewhat disappointingly, Patently Apple reports that this particular patent only describes an optical zoom of 3x, which isn't much more than the 2.5x optical zoom found on the iPhone 12 Pro Max. Considering that periscope camera systems are capable of considerably more zoom compressed into a tight space -- as mentioned, the Samsung Galaxy S21 Ultra achieves 10x optical zoom with its periscope camera -- 3x zoom feels far short of what consumers would likely expect out of a periscope system in an Apple device. It's one thing to be late to the game -- which Apple already is -- but another to be late as well as worse.

Whatever the case, if Kuo is to be believed, this patent along with the other periscope designs Apple has patented thus far won't see use in a camera system until at least 2023.
