Oppo today new technologies in the field of cameras. The improvements are mainly focused on sensors, camera modules and algorithms.
Oppo said he has focused on optimizing imaging technology, which will allow users to “capture the beauty of life with ease.”
Innovations include Next-generation RGBW sensor, 85-200mm progressive optical zoom, five-axis OIS technology and the next generation of under-display cameras.
Next generation RGBW sensor
OPPO’s next-generation RGBW sensor significantly improves light sensitivity, introducing additional white sub-pixels (W), innovative DTI technology and OPPO’s self-developed 4-in-1 pixel algorithm.
As a result, the new sensor capture 60% more light than previous sensors at the same time reduces noise by up to 35%, allowing for much clearer and brighter images in low light conditions.
The next-generation RGBW sensor is produced using state-of-the-art manufacturing and processing technology, increasing the level of computing power needed to run complex algorithms and maximizing the amount of data extracted via the sensor’s white pixels.
OPPO’s proprietary 4-in-1 pixel algorithm helps to substantially improve sensor color performance by preventing defects or inaccuracies in color patterns. In addition, DTI pixel isolation technology and DeepSi processing on the new sensor effectively prevents subpixel interference and improves image quality.
Not only is capturing photos in low light conditions improved, but also The latest generation RGBW sensor makes portraits more expressive in photos and videos through improvements in skin, texture and contrast.
The new sensor will be available in OPPO products marketed from the fourth quarter of 2021.
85-200mm progressive optical zoom
The 85-200mm progressive optical zoom module represents a redesign of the structural module at the hardware level.
first adopt G + P lens technology (glass + plastic), introducing two ultra-thin, high-precision glass lenses to significantly enhance optical effects and minimize dead light.
The innovative application of a magnetoresistance sensor (TMR sensor) allows the camera module lenses to work with greater stability and precision.
The guide axis motor increases the dynamic tilt with which the lens system can be moved, allowing progressive optical zoom at higher magnifications.
These innovations support the progressive optical zoom at equivalent focal lengths between 85 and 200 mm, get sharp images at all zoom magnification levels, from close-up portraits to distant landscapes, without the need for cropping and retouching.
Users will be able to receive a smooth transition across the entire optical zoom range with image quality comparable to that of a professional camera. In addition, this technology prevents common issues such as level skip, inaccurate white balance, or distorted colors that can appear on systems with cameras at different zoom levels.
Five-Axis Optical Stabilization
Another novelty is the five-axis OIS that allows the processor to receive movement data from the gyroscope, analyze it and divide it into their respective parts using algorithms and then pass this data to the lens and image sensor, which are managed by ball bearing motors and shape memory alloys, respectively.
When movement is relatively small, images are stabilized by the OIS lens shift, which covers the horizontal (X) and vertical (Y) shift.
Although, when the movement is relatively large, the displacement of the OIS sensor will be used additionally, which includes horizontal shift (X), vertical shift (Y) and wobble, thus achieving five-axis stabilization along with the compensation algorithm.
This allows for a maximum stabilization angle ± 3º, three times more than traditional OIS technology in mobile devices, while the sensor can also change with an accuracy of 2μm.
For night or moving photos, OPPO’s proprietary algorithm technology will significantly improve color stability, clarity, and performance; increasing vibration compensation by up to 65%.
OPPO’s five-axis ISO will be available in the products that OPPO will market from the first quarter of 2022.
Next generation of under the screen cameras
Also new is the next generation of under-screen cameras that new smartphones will bring.
The innovative pixel geometry offers a 400 dpi high quality display in the area where the camera is located below the screen.
With transparent cabling and a new design, the result is much better viewing quality with a smoother viewing experience.
With pixel circuitry that handles only 1 pixel (“1 to 1”) on the screen and OPPO compensation algorithm technology, the chromaticity and brightness of the entire screen are more precisely controlled., with a deviation of only about 2% and an improvement in screen life of up to 50%.
Furthermore, the Research Institute of OPPO en EE. UU. It has developed a series of image artificial intelligence algorithms, which include diffraction reduction, anti-condensation, HDR and AWB, to improve the image quality of the camera under the screen.
The OPPO AI diffraction reduction model has been tested using tens of thousands of images to analyze problems caused by diffraction in the light source, making it possible for users to obtain clearer, more natural-looking images in the future.
