OPPO unveils new technology for its next-gen under-screen camera

OPPO has introduced a series of breakthroughs in smartphone imaging technology in the 2021 OPPO Future Imaging Technology Launch Event held on Aug. 19. Among the innovations featured on the online event is the Chinese manufacturer’s next-generation under-screen camera with a series of proprietary AI algorithms.

OPPO unveiled the world’s first-ever under-screen camera technology back in 2019 at the MWC event in Shanghai. In last week’s event, the company said its new under-screen camera solution for future smartphones ensures a 400-PPI high-quality display.

Using transparent wiring and a new design, the result is much finer display quality with a smoother visual experience. With each pixel circuit driving only 1 pixel (1:1) in the screen and OPPO’s precise algorithmic compensation technology, the chromaticity and brightness of the entire screen are more precisely controlled, with a deviation of only about 2% and an improved screen lifespan of up to 50%.

In addition, OPPO’s U.S. Research Institute has developed a series of imaging AI algorithms—including diffraction reduction, anti-condensation, HDR, and AWB—to better optimize the imaging quality of the under-screen camera. OPPO’s AI diffraction reduction model has been trained to control problems caused by diffraction at the light source for clearer, more natural-looking images.

Apart from this new breakthrough, OPPO featured other innovations during last week’s event, including its next-generation RGBW sensor, the 85-200mm Continuous Optical Zoom, and Five-axis OIS technology.

Next-generation RGBW sensor

OPPO’s next-generation RGBW sensor is made using advanced manufacturing and processing technology, increasing the level of computing power needed to execute complex algorithms and maximizing the amount of data extracted via the sensor’s white pixels.

The company’s proprietary 4-in-1 pixel algorithm helps to substantially boost the sensor’s color performance, preventing issues such as color inaccuracy and moiré patterns. In addition, industry-leading DTI pixel isolation technology on the new sensor effectively prevents sub-pixel crosstalk and improves image quality.

The new sensor allows for 60% more light to be captured than previous sensors while achieving an up to 35% reduction in noise to deliver much clearer and brighter images in low-light conditions. It also makes portraits more expressive in both photo and video with enhancements to skin, texture, and contrast. The new sensor will be commercially released in OPPO products from Q4 2021.

85-200mm Continuous Optical Zoom

The new 85-200mm Continuous Optical Zoom uses G+P (glass + plastic) lens technology for its two ultra-thin, high-precision aspheric glass lenses to significantly boost optical effects, such as minimizing stray light. Meanwhile, the application of a tunnel magnetoresistance sensor (TMR sensor) allows the lenses within the camera module to move with more stability and precision.

These innovations support Continuous Optical Zoom at equivalent focal lengths between 85mm and 200mm, capturing sharp images from up-close portraits to far-away landscapes without cropping.

Users can enjoy a smooth transition throughout the zoom range with image quality comparable to that of a professional camera. It also avoids common conventional multi-camera zoom systems problems like jumping, white balance inaccuracy, or color bias.

Five-axis OIS

The Five-axis OIS allows the system processor to receive movement data from the gyroscope, analyze it and break it down into its respective components through algorithms.

It allows maximum image stabilization three times more than traditional OIS technology on mobile devices, while the sensor can also shift with a precision of 2μm. For night-time or motion shots, OPPO’s proprietary algorithm technology can help significantly improve stability, clarity, and color performance; increasing the vibration compensation performance by up to 65%. The OPPO Five-axis OIS will be commercially released in OPPO products from Q1 2022.

OPPO is further strengthening its global R&D capacities to meet the ever-changing imaging demands of users worldwide. Among those is the Imaging Lab in Yokohama, Japan, which is responsible for creating a number of OPPO’s self-developed imaging technologies found in the Reno series, including the Reno6 Series which was recently launched in the Philippines.

Moving forward, OPPO will continue to focus on the implementation of self-developed imaging technologies and further strengthen its cooperation with industry partners to provide users with an even better imaging experience.
