Smart device brand Oppo held the 2021 Oppo Future Imaging Technology launch event where it unveiled a series of breakthroughs in smartphone imaging technology focused on upgrades to sensors, modules, and algorithms. The company has been focusing on self-development and optimization of underlying imaging technologies in order to enable users to “capture the beauty in life with ease”.
Innovations
Oppo's next-generation RGBW sensor, the 85-200mm Continuous Optical Zoom, Five-axis OIS technology, and next-generation under-screen camera comes with a series of proprietary AI algorithms.
New Sensor: The next-generation RGBW sensor enhances light sensitivity with improved color performanc--improves light sensitivity by introducing additional white sub-pixels(W), DTI technology, and Oppo’s self-developed 4-in-1 pixel algorithm. As a result of these innovations, the new sensor allows for 60 percent more light to be captured than previous sensors while achieving an up to 35 percent reduction in noise to deliver much clearer and brighter images in low-light conditions.
The 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.
Oppo'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. Also, industry-leading DTI pixel isolation technology on the new sensor effectively prevent sub-pixel crosstalk and improve image quality.
More than just improving low-light photo capturing, the next-generation RGBW sensor is also able to make 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.
New Modules:
OPPO 85-200mm Continuous Optical Zoom supports super smooth zoom, and OPPO Five-axis OIS guarantees clearer snapshots
• 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.
These innovations support Continuous Optical Zoom at equivalent focal lengths between 85mm and 200mm, capturing sharp images at every magnification level, from up close and personal portraits to far-away landscapes, with no need to crop. Users can enjoy a smooth transition throughout the zoom range with image quality comparable to that of a professional camera. This technology avoids common problems like jumping, white balance inaccuracy, or color bias that conventional multi-camera zoom systems may experience.
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. 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.
When the movement is relatively small, images are stabilized mainly through lens-shift OIS – covering horizontal (X) and vertical (Y) shifting. When the amplitude of the movement is relatively large, however, sensor-shift OIS will also be utilized – including horizontal shifting (x), vertical shifting (y), and rolling – together with algorithm compensation, to achieve stabilization in five-axis 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 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.
