The level of technological advancement of OPPO It is not accidental or spontaneous but the result of research. Nowadays, OPPO has 6 research institutes, 5 research centers and development and dozens of imaging labs around the world, including the new imaging lab in Hyderabad, India, and the imaging lab in Yokohama, Japan, which is responsible for creating a number of self-developed imaging technologies for OPPO found in the Reno series.

OPPO, knows that users are looking for the best cameras on all ranges of smartphones. Therefore, the company aims to allow users to “capture the beauty of life with ease.” Among these innovations OPPO announced an all-new RGBW sensor, a continuous optical zoom, five-axis optical image stabilization and the next-generation under-display camera.
Next-gen RGBW sensor from OPPO
The new next generation RGBW sensor improves sensitivity to light with improved color performance, to ensure better captures with ease with every shot.
More than just improving low-light photo capture, RGBW sensor can also make portraits more expressive both in photos and in video with improvements in skin, texture and contrast. The new sensor will be launched commercially in the products OPPO as of the fourth quarter of 2021.
This, thanks to the technology of OPPO RGBW sensor introduces white sub-pixels (W) devices, the innovative DTI (Deep Trench Isolation) technology, and the 4-in-1 pixel algorithm developed by OPPO. As a result of these innovations, new sensor captures 60% more light than previous sensors and at the same time reduces noise by up to 35% for much clearer and brighter images in low light conditions.
OPPO’s proprietary 4-in-1 pixel algorithm increases sensor color performance, avoiding problems such as color inaccuracy and moire patterns (which is an interference pattern formed by lines). What’s more, OPPO integrates DTI pixel isolation technology, currently an industry leader and DeepSi processing, on the new sensor to avoid sub-pixel crosstalk (which is when one circuit disturbs another), thereby improving image quality.
New Modules: a delicate zoom and more stability
OPPO redesigns the structural module of hardware level cameras, thus The new OPPO 85-200mm lossless continuous optical zoom Supports super smooth zoom, and the five-axis optical image stabilizer of OPPO ensures clearer photos.
These innovations support Lossless continuous optical zoom at impressive focal lengths between 85mm and 200mm, capturing sharp images at all magnification levels, from close and personal portraits to distant landscapes, without the need for cropping.
The new level of technology for smartphones is comparable to a professional camera. This technology avoids common problems such as skipping, inaccuracies in white balance, or color skew that conventional multi-camera zoom systems may experience. At the hardware level, the innovations are:
– Adopt G + P lens technology (glass + plastic)– For the first time integrates two ultra-thin, high-precision aspherical glass lenses to significantly increase optical effects, such as minimizing stray light.
– The innovative application of a tunnel magnetoresistance sensor (TMR sensor) allows the lenses within the camera module to move with more stability and precision.
– Updated guide shaft motor increases dynamic tilt to which the lens system can be moved, easily supporting lossless continuous optical zoom at higher magnifications.
OPPO’s new five-axis optical image stabilizer
New 5-axis optical stabilizer enables impressive night or motion shots, thanks to the patented algorithm technology of OPPO can help to significantly improve color stability, clarity and performance;
Also the image stabilizer increases vibration compensation performance by up to 65%. The new five-axis optical image stabilizer from OPPO, allows the system processor to receive movement data from the gyroscope, analyze it and divide it into its respective components through algorithms.
A) Yes, when the movement is relatively small, images are mainly stabilized via lens shift OIS, covering horizontal (X) and vertical (Y) shift.
Secondly, when the range of motion is relatively large, Sensor offset OIS, including horizontal offset (x), vertical offset (y), and roll, along with algorithm compensation, will also be used to achieve stabilization in five axes of space.
This allows a maximum stabilization angle of ± 3, three times more than traditional OIS technology on mobile devices, while the sensor can also change with an accuracy of 2μm. OPPO’s five-axis OIS will be launched commercially in products OPPO from Q1 of 2022.
New algorithm developed by OPPO
The self-developed algorithms of OPPO they are compatible with the next generation of under-screen cameras to offer the perfect balance between screen and camera quality, not bad huh? Aesthetics and image quality.
OPPO showcased its next-gen under-display camera solution for future smartphones. The innovative pixel geometry guarantees a high-quality 400 PPI display in the camera area below the screen. OPPO managed to control the chromaticity and brightness of the entire screen more precisely, with a deviation of around 2% only and an improved screen life of up to 50%.
This, thanks to the fact that it uses transparent wiring and a new design, the result is much finer viewing quality with a smoother viewing experience. With each pixel circuit driving only 1 pixel (“1-to-1”) on the screen and precise algorithmic compensation technology of OPPO.
In addition, the OPPO Research Institute in the United States has developed a series of image AI algorithms, including diffraction reduction, anti-condensation, HDR and AWB, to optimize better the image quality of the camera below the screen.
Diffraction is the phenomenon of distortion of the light that the camera sensor receives in a distorted way. Thus, OPPO’s AI Diffraction Reduction Model has been trained using tens of thousands of images to control problems caused by diffraction in the light source, allowing users to capture clearer, more natural-looking images.
OPPO’s commitment to imaging technology is reflected in the resultss that have been harvested on this front, as the OPPO Find X3 Pro received the “EISA Best Product Advanced Smartphone 2021-2022” award. This award, granted by the Expert Image and Sound Association (EISA), which brings together the 61 most renowned consumer technology publications in the world.
