During the 2021 OPPO Future Imaging Technology event, the company unveiled a series of breakthrough technologies in the area of smartphone image capture and processing, focusing on the comprehensive enhancement of sensors, modules and algorithms.
Among the innovative technologies, OPPO presented: a new generation RGBW sensor, a smooth 85-200mm optical zoom, five-axis optical stabilization technology (OIS) and the next generation of the camera hidden under the screen (USC) supported by proprietary AI algorithms. Thanks to these technologies, OPPO has achieved a leap forward in the field of recording and image processing technologies in smartphones, incl. in the area of photosensitivity, the possibility of zooming, stabilization or research on the shape of the product.
New generation RGBW sensor with increased photosensitivity and better colour reproduction
The new generation of OPPO RGBW sensor introduces additional white sub-pixels (W), breakthrough DTI technology and the 4-in-1 pixel algorithm developed by OPPO. All this significantly improves the sensor's response to light - it allows you to capture 60% more light than the previous generation sensors, while reducing noise up to 35% for clearer and brighter images in low light conditions.
OPPO's patented 4-in-1 pixel algorithm helps increase the sensor's color performance by preventing problems such as color inaccuracy and moiré patterns. In turn, the DTI pixel isolation technology, implemented in the new sensor, effectively prevents sub-pixel crosstalk and improves image quality. The new sensor will be commercially available in OPPO products from the fourth quarter of 2021.
OPPO 85-200mm optical zoom
Another innovation is the smooth lossless optical zoom that redesigns the basic structural module at the hardware level. P For the first time, G+P (glass+plastic) lens technology has been applied, introducing two ultra-thin high-precision glass aspherical lenses that greatly enhance optical effects. The tunnel magneto-resistive sensor (TMR sensor) allows the lenses in the camera module to move with greater stability and precision, while the newly upgraded guide system increases the dynamic tilt at which the lens assembly can be moved, which significantly affects the lossless optical zoom handling at higher magnifications.
The above innovative OPPO solutions support lossless optical zoom at equivalent focal lengths from 85mm to 200mm, capturing clear photos no matter what the magnification is, from close-up and close-up portraits to distant landscapes, without the need for cropping.
Five-axis optical stabilization system (OIS)
The new five-axis OIS from OPPO enables the system processor to collect motion data from the gyroscope, which is then analyzed and decomposed into appropriate components using algorithms. This data is then transferred to two moving parts: the lens and the image sensor. When there is little object movement, images are mainly stabilized by lens shift OIS. However, when the amplitude of the movement is relatively large, OIS with sensor shift will also be used - so as to obtain stabilization in five spatial axes. The five-axis OIS OPPO will be launched on the market in OPPO products from the first quarter of 2022.
The camera hidden under the screen and the AI imaging algorithms supporting it
OPPO also unveiled a new generation of its Under-Screen Camera (USC). Through the use of transparent cabling and a new design, a much better display quality and a smoother visual experience are achieved, and the innovative pixel geometry provides a display quality of 400 PPI in the area above the USC camera. Additionally, a number of AI imaging algorithms - including diffraction reduction, anti-condensation, HDR and AWB - have been developed to optimize the imaging quality of the camera hidden under the screen.
