A Closer Look at Oppo’s Retractable Smartphone Camera

Last week, Oppo teased that it would be releasing a smartphone that featured a retractable, telescoping camera. While the company has not officially announced it yet, it has revealed more information on the coming device.

The company recently hosted its annual Inno Day event where it announced a few new products through the digital experience, including the new MariSilicon X mobile neural processing unit that it claims will dramatically improve image quality in its 2022 devices.

On top of the new processing power, Oppo's retractable smartphone camera appears to be adding hardware advancements into the equation. The company has published a video about it along with six major features that come with it. Typically, retractable lenses on compact cameras usually allow an optic to have variable focal lengths or at least allow a lens with multiple elements to make itself more compact when not in use. That benefit is on full display here, as the company has managed to pack the larger camera system into an 8.26mm phone (a measurement reported by GSMArena) without a particularly large camera bump. When not in use, the lens pulls back to be flush with the thin phone body

In Oppo's case, the camera will not have a variable focal length but instead will feature a 52mm equivalent lens (which the company classifies as 2x optical zoom) when extended. Behind the lens is a large 1/1.56-inch Sony IMX766 sensor which will likely capture more detail compared to a standard telephoto module. The actual optical system is also touted by the company as providing actual telephoto bokeh.

Oppo says the lens system will support optical image stabilization (OIS) as well as autofocus (AF) but does not go into more detail about the focusing performance that can be expected, as the demonstration looks to be pretty strongly focused on the hardware.

One of the more impressive features Oppo demonstrated is the ability for the phone to sense if it has been dropped and automatically retract the lens to prevent damage. The company claims that it is able to fully retract the lens back into the smartphone body in just 0.6 seconds. On top of all of this, the company says it will remain splash and dust resistant but did not go into specific details on how robust that resistance would be.

Oppo is expected to announce a new Find X flagship mobile device that also includes the company's new NPU in the first quarter of 2022, but it did not hint if the retractable smartphone camera would be part of that device or a separate launch. Whatever the case, the design is clearly more than a prototype and it will likely find its way into a consumer device by next year.

Oppo Teases a Telescoping, Retractable Smartphone Camera

Oppo has published a short video that teases a coming smartphone that will feature a telescoping, retractable camera with a design that is reminiscent of compact point and shoots.

A telescoping, retractable lens design usually allows an optic to have variable focal lengths or at least allow a lens with multiple elements to make itself more compact when not in use. Whatever the case, improved performance is all but assured to be a goal from Oppo with this design.

It should also be noted that the module is quite large, which hints at either a larger image sensor, larger and higher-quality optics, or both.

Most pop-ups are annoying…

But not our self-developed retractable camera! 😉

Earlier this month, Oppo announced that it would be one of the first smartphone manufacturers to feature the Qualcomm Snapdragon 8 Gen 1 processer in its devices and planned to make it available in the first quarter of 2022.

“Oppo maintains close ties with Qualcomm Technologies, and we have brought several 5G smartphones powered by flagship Snapdragon mobile platforms to the market this year, including the Find X3 series and Reno6 series," Scott Zhang, Oppo Vice President of Overseas Sales says. "It is our pleasure to witness the launch of a new generation of Snapdragon 8 Mobile Platform. We believe it will bring immense improvements and powerful performance on the next generation of flagship smartphones.”

The announcement of the feature is without many confirmed details, as Oppo plans to fully reveal the smartphone and camera on December 14 at its Inno Day event, which takes place in Shenzhen, China on December 14 and 15. Inno World, where the smartphone is likely to make an appearance, is a virtual stage that takes place during its Inno Day, which is the company's platform for showcasing its coming products and technologies since 2019.

Last year, Oppo showcased three conceptual products at Inno Day, including a rollable smartphone. For 2021, OPPO says it is digitalizing the launch event and exhibitions and transforming the conventional event into an entertaining and interactive world of virtual experiences.

Since Oppo plans to unveil the phone next week and it has already said that it will integrate Qualcomm's new processor into a device for sale in quarter one of 2022, it's not much of a leap to assume these devices will be one and the same. While speculation, it is all likely to become clear on December 14.

Vivo Designed a Pop-Up Multi-Zoom Telescoping Smartphone Camera

Chinese smartphone manufacturer Vivo has recently published schematics for a pyramid-like smartphone camera design that stacks multiple lenses on top of each other in a unique telescoping camera mechanism.

According to documentation on the design, Vivo wanted to try and get over a challenging hump: smartphones currently only support a small number of multiple-zoom options. This new method would enable it to make a larger zoom range possible within the small chassis of a smartphone and offer what appears to be at least four zoom options.

Unlike other pop-up camera designs that have been either patented or even implemented in the past, Vivo's choice here wouldn't be to have the cameras act as a selfie camera, but instead point towards the back of the camera and operate as the full main camera array for the system. The benefits of this design are twofold. First, the phone can be slim and seamless all around and would not require a camera bump because the cameras would not be visible unless activated. Second, multiple cameras could be hidden on top of each other and potentially overlap, which would allow Vivo multiple different focal lengths of increasing zoom factor in this one system.

The patent also notes that the front-facing selfie camera would be an under-display type, which means this particular option would feature a set of cameras that use technology that is already on the bleeding edge before the pyramid-like telescoping system is considered. In short, Vivo is trying a lot of unproven ideas in one device. Curiously, a pop-up camera has been one solution to providing a seamless display to a smartphone and once under-display tech has been advanced to a certain point, many would think that the pop-up design would no longer be necessary. Clearly, Vivo disagrees.

According to renders and explanations from LetsGoDigital, Vivo's telescoping camera could be extended in four steps, and one camera lens extends at a time. The bottom lens would always pop up when the camera app is activated and the other lenses would appear as they are requested through the app software.

As mentioned, the lenses could potentially overlap and allow for multiple different optical zoom arrangements in the same camera and while Vivo doesn't specify exactly how much optical zoom can be expected here, the company does say it would be considerably more than any current system using a periscope lens design.

As is the case with any pop-up or removable system in a smartphone, the major issue that Vivo would run into is durability. Not only would this design require a set of moving parts that, at any number of points, could fail, but the entire pyramid-like system could also easily be snapped off if not retracted correctly.

Even though this design has its flaws which make it unlikely to come to market, Vivo is showing that it is not afraid to imagine different possibilities other manufacturers would be quick to disregard. Earlier this year, Vivo also patented a smartphone that includes a tiny quadcopter drone that slides out from the main body of the device, detaches, and can fly away to allow for better selfie photos. Compared to that, a telescoping camera system seems far more likely.
