Oppo unveils new smartphone imaging technologies like 85-200mm optical zoom lens and next-generation RGBW image sensor

Chinese smartphone maker Oppo has unveiled several new smartphone imaging technologies during its Future Imaging Technology virtual event yesterday.

Among them are Oppo’s next-generation RGBW image sensor, the 85-200mm continuous optical zoom module, a five-axis optical image stabilisation (OIS) technology, and under-screen camera as well as a series of proprietary artificial intelligence (AI) algorithms.

Oppo’s next-generation RGBW image sensor is said to significantly improve light sensitivity by introducing an additional white (thus adding W into the traditional RGB) sub-pixel and its 4-in-1 pixel algorithm.

Oppo claims that this new image sensor allows for 60 per cent more light to be captured and 35 per cent less noise compared to traditional image sensors. The new image sensor, which will be available in Q4 this year, is also supposed to make portraits more expressive in both photo and video.

In addition, Oppo showcased its 85-200mm optical zoom module. It adopts glass and plastic lens technology with two ultra-thin and high-precision aspheric glass lenses to boost optical effects and minimise stray light.

The use of a tunnel magnetoresistance sensor allows the lenses within the camera module to move with more stability and precision, while a newly upgraded guiding shaft motor increases the dynamic tilt at which the lens system can be moved.

Another new smartphone imaging technology from Oppo is the five-axis OIS that allows the system processor to receive movement data from the gyroscope, analyse 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 – to reduce camera shake.

Finally, Oppo uses a combination of hardware and software to improve its under-screen camera. In terms of hardware, Oppo uses transparent wiring and re-designed circuitry for finer display quality – 400 pixels per inch – with a smoother visual experience.

At the same time, Oppo uses its proprietary AI algorithms to compensate for the diffraction caused by the display on top of the under-screen camera. This technology is expected to be available on Oppo smartphones early next year.
