At their Future Imaging Technology launch event, OPPO has just shown off a number of enhancements and breakthroughs when it comes to smartphone imaging technology focused on upgrades to sensors, modules, and algorithms. The innovations include OPPO’s next-generation RGBW sensor, OPPO’s 85-200mm continuous optical zoom, OPPO’s Five-axis OIS technology, and OPPO’s next-generation under-screen camera. Below is a breakdown of each of the new features OPPO fans can expect to arrive on future handsets in the future. 

A new and improved RGBW sensor

OPPO’s new RGBW sensor significantly improves light sensitivity by introducing additional white sub-pixels (the ‘W’ in the RGBW abbreviation),  DTI technology, and OPPO’s self-developed 4-in-1 pixel algorithm.

OPPO RGBW sensor configurationAll of these combined is said to offer improved low-light capture with the new sensor capturing 60% more light than previous sensors while reducing noise in the picture up to 35%. With this sensor, users should expect clearer and brighter images in low-light conditions. Here’s a sample of the sensor in action below on an extremely low-lit scene:

The upgraded sensor is also said to offer improved colour performance. This is done by the increased horsepower on the device being used by the new sensor to maximise the amount of data it pulls from the new white sub-pixels. OPPO’s own 4-in-1 algorithm also boosts the sensor’s colour performance, helping to keep colour inaccuracy in check. The new sensor will also result in improvements to photo and video portraits with skin, texture and contrast all getting a bump in overall quality. This new sensor will be making its way to new OPPO products before the end of this year. 

New ‘Super Smooth Zoom’ modules

OPPO’s showed off their new 85-200mm ‘zoom’ module which delivers continuous optical zoom so you can get some super smooth zoom when shooting videos or photos. The below GIF showcases the new module in action.

The module avoids problems like jumping, white balance inaccuracy, and colour bias OPPO says people experience when using conventional multi-camera zoom systems. The module redesigns the hardware of the existing structural module, with advancements including: 

  • Adoption of G+P (glass + plastic) lens technology with two ultra-thin, high-precision aspheric glass lenses to boost optical effects such as minimising stray light.
  • A tunnel magnetoresistance sensor (TMR sensor) to allow the lenses within the camera module to move with increased stability and precision.
  • An upgraded guiding shaft motor to increase the dynamic tilt which the lens system can be moved at, supporting continuous optical zoom at higher magnifications.

New Five-Axis OIS

The new OPPO five-axis OIS should result in much clearer snapshots as it gathers and analyses movement data from the phone’s built in gyroscope and then uses algorithms to break it down into respective components. The data is passed to the lens and image sensor, which are driven by ball-bearing motors and shape memory alloys.

When the amplitude of the movement dedicated by the phone is fairly intense, it will use its new sensor-shift OIS, similar to what Apple introduced with last year’s iPhone 12 Pro Max. The OIS will also include horizontal shifting (x), vertical shifting (y), and rolling – together with algorithm compensation, to achieve five-axis stabilisation.

All of this allows a maximum stabilisation 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 is also said to improve stability, clarity, and colour performance, increasing the vibration compensation performance by up to 65%. The OPPO Five-axis OIS will start making its way into OPPO products from the start of next year, Q1 2022.

New OPPO algorithm will allow for next-generation Under Screen Camera (USC) breakthroughs.

Finally, OPPO showcased its next-generation under-screen camera solution for future smartphones. The new and improved pixel geometry will allow for a 400-PPI high-quality display in the above the in-screen display, significantly higher PPI then what’s being achieved by Samsung’s Galaxy Fold3 implementation of its under-display camera tech.

OPPO is achieving this by using transparent wiring and a new design which, together, provides clear display quality with a smoother, more seamless look overall. OPPO’s proprietary screen technology enables each pixel circuit to drive only 1 pixel. Combined with OPPO’s algorithmic compensation technology, this allows the screen brightness to be controlled with a deviation of about 2%, and an improved screen lifespan of up to 50%.

OPPO’s Research Institute has also developed a series of imaging AI algorithms including diffraction reduction, anti-condensation, HDR and AWB, to optimise imaging quality of the under-screen camera. By training its AI diffraction reduction model using tens of thousands of images to control problems caused by light diffraction, users can capture clearer, more natural images.

This new USC technology should be making its way to OPPO handsets from the start of 2022 onwards. You can watch the full presentation below:
