Oppo unveils phone offering five times lossless zoom
CHINESE phone giant Oppo has unveiled what it is describing as a 'ground breaking' five time dual camera zoom to rival the two times zoom on Apple iPhone 7 Plus.
Oppo unveiled the technology at Mobile World Congress (MWC) 2017, saying it offered 5x lossless zoom capability as well as image stabilisation.
The tech giant says it worked for almost a year to develop the periscope-styled dual-camera technology. Currently, more than 50 patents have been filed for this technology.
There's no word on when the phone is expected to be released, but it is tipped to be some time this year.
Sky Li, OPPO Vice President and Managing Director of International Mobile Business, said, "The '5x Dual Camera Zoom' has opened up yet another realm of possibility in terms of smartphone photography and is a reflection of our dedication to delivering on what our customers want and need - to take beautiful and clear pictures".
The Innovation behind the "5x Dual-Camera Zoom"
Oppo says tthe "5x Dual Camera Zoom" technology was inspired by the idea of a periscope on a submarine.
The dual camera utilises wide-angle and telephoto lenses, and the housing for the telephoto lens uses an innovative periscope-style structure.
By shifting the angle of the telephoto lens by 90 degrees, the lens will have the space it needs for a deep zoom.
A periscope-style prism then directs the path of the light entering the camera by 90 degrees, and sends the image through the telephoto lens when the user zooms in on a subject or object.
"This new dual-camera setup helps to keep a smartphone thin. The 3x optical zoom, matched with a proprietary image fusion technology for digital zoom, gives users the industry's first-ever lossless 5x dual camera zoom,'' Oppo said in a statement.
"Thanks to the periscope-style construction, the 5x dual camera module is now only 5.7mm thick, which is 10 percent thinner than a typical 2x optical zoom lens in a smartphone."
Oppo says the other breakthrough is the Optical Image Stabilisation (OIS) solution.
"Typically, when the zoom factor increases in capturing an image, even the slightest vibrations can have a dramatic effect on the clarity of the image.
" Different from other manufacturers who use optical image stabilization on the wide-angle lens, OPPO took a new approach and applied OIS directly to the telephoto lens."
"Through the OIS technology, both the prism and telephoto lens intelligently sense vibrations and compensate in real time.
"The all-new OIS solution can improve the performance of previous generations by 40 per cent, and the prism mechanism dynamically adjusts its angle at precise increments of 0.0025o. This technology ensures images are clear and stable even at full 5x zoom."
"We are definitely putting a stake in the ground in terms of technological breakthroughs for mobile photography,'' Sky Li said.
"The dual cameras with wide-angled and telephoto lens, together with the periscope-style construction, our image fusion technology and the Optical Image Stabilisation, edges mobile photography even closer to what digital cameras are capable of doing.''
So who is Oppo and what do they focus on?
Oppo says it has had a singular focus on being a leader in mobile photography.
In 2012, it started the trend of beautification of selfie pictures.
In 2016, Oppo announced the 'Selfie Expert' F-series, with the flagship F1 Plus model the first device ever to pack a 16 megapixel front camera.
In the same year, Oppo worked with Sony to co-develop the customized 1/2.8-inch IMX398 sensor with a big f/1.7 aperture for its R9s model.
Oppo is now the No. 1 smartphone brand in China with 16.8 percent market share, and the world's fourth best-selling smartphone brand, according to IDC.
It has rapidly expanded globally, totalling 28 global markets, to date.
In Southeast Asia, Oppo has risen to No. 2 in the region in a very short time period, according to IDC.
