Global smart device brand OPPO today held the 2021 OPPO Future Imaging Technology Launch Event. The company unveiled a series of breakthroughs in smartphone imaging technology focused on upgrades to sensors, modules, and algorithms, enabling users to “capture the beauty in life with ease.”
Among the innovations featured are: OPPO’s next-generation RGBW sensor, the 85-200mm Continuous Optical Zoom, Five-axis OIS technology, and next-generation under-screen camera with a series of proprietary AI algorithms.
The next-generation RGBW sensor enhances light sensitivity with improved color performance. 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.
OPPO’s 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. According to OPPO the new sensor will be commercially released in OPPO products from Q4 2021.
OPPO 85-200mm Continuous Optical Zoom
The new-released module is the 85-200mm Continuous Optical Zoom, which redesigns the underlying structural module at the hardware level:
- It adopts G+P (glass + plastic) lens technology for the first time, introducing two ultra-thin, high-precision aspheric glass lenses to significantly boost 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.
- The newly upgraded guiding shaft motor increases the dynamic tilt at which the lens system can be moved, easily supporting Continuous Optical Zoom at higher magnifications.
OPPO Five-axis OIS Technology
The new 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. The data is then passed to the two moveable components: the lens and the image sensor, which are driven by ball-bearing motors and shape memory alloys, respectively.
For relatively small movements, images are stabilized mainly through lens-shift OIS. While for relatively large movements, sensor-shift OIS will also be utilized – together with algorithm compensation, to achieve stabilization in five-axis of space. According to OPPO, the OPPO Five-axis OIS will be commercially released in OPPO products from Q1 2022.
OPPO Next-gen Under-screen Camera
OPPO also showcased its next-generation under-screen camera solution for future smartphones, ensuring 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-to-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%.
OPPO Next Generation Under-Screen Camera Pixel Array:
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.
