OPPO held an online future imaging technology launch event to provide some camera related announcements, after unveiling its next generation under-screen selfie camera earlier this month.
The company is known for demonstrating its camera technology in a prototype long before it was brought to the market.
The company was the first to feature periscope telephoto and underscreen cameras, for example, both of which are increasingly popular across high-end devices.
And the new announcement concerns a telephoto lens with a continuous optical zoom. Unlike the telephoto periscope lenses in use today, the lens elements move across the 85-200mm magnification range which means images should be sharp at every focal length without the need for digital zoom or cropping.
Vivo announced a similar product to its Apex 2020. But the range was more limited, roughly 130-195 millimeters.
The OPPO unit starts at 85mm, which is a common focal length for portrait images, making it even more versatile. The company notes that using a single camera across more focal lengths ensures more consistent performance in terms of color and white balance as well.
But the company does not say when this camera could be shipped via a commercial device.
The next announcement is about a 5-axis optical image stabilization system that uses lens shift and sensor shift techniques as well as motion data from a phone's gyroscope.
Lens shifting is used for more gradual stabilization, while sensor shifting is applied for more dramatic situations. It includes the ability to rotate the sensor as well as along the X and Y axes.
The company says this allows for three times better stability than you can achieve with regular OIS camera modules, which is also what Vivo says about gimbal-style systems shipped since last year.
Contrary to the zoom lens, Oppo confirms the time frame for the release of the OIS system, as it begins appearing on its phones in the first quarter of 2022.
The company's latest major announcement concerns a new image sensor that uses the RGBW sub-pixel format. Which adds extra white sub-pixels for what the company claims is a 60 percent increase in light sensitivity.
The company acknowledges that previous attempts at RGBW sensors have had their limitations. But she believes the new effort should make a huge difference because of more advanced manufacturing processes and improved demystification algorithms.
And the sensor will be available soon, too. The company says it appears in phones shipped in the fourth quarter of 2021.
