Oppo, the Chinese smartphone behemoth, has unveiled a slew of new camera innovations at its event today. Sensors, modules, and algorithms for smartphone cameras have all been upgraded. According to Oppo, it has been focusing on self-development and optimization of underlying imaging technologies to enable users to “capture the beauty in life with ease.” Oppo’s new RGBW sensor, 5-200mm Continuous Optical Zoom, Five-axis OIS technology, and next-generation under-screen camera with a series of proprietary AI algorithms are among the newly announced camera innovations. Let’s take a look at the Oppo event’s new camera innovation technology.
Oppo has unveiled a new RGBW sensor
At its camera innovation event, Oppo unveiled a new RGBW sensor. According to the manufacturer, the new sensor improves light sensitivity while also improving color performance. Additional white sub-pixels, DTI technology, and Oppo’s self-developed 4-in-1 pixel algorithm help the sensor achieve this. As a result, the new sensor can capture 60 percent more light than previous sensors while also reducing noise by up to 35 percent, resulting in much clearer and brighter images in low-light situations. With improvements to skin, texture, and contrast, the next-generation RGBW sensor can make portraits more expressive in both photo and video. From Q4 2021, the new sensor will be commercially available in Oppo products.
New continuous optical zoom of 85-200mm
Oppo unveiled its new 85-200mm Continuous Optical Zoom module, which uses glass + plastic (G + P) technology, at the camera innovation event. It makes use of two ultra-thin, high-precision aspheric glass lenses to boost optical effects like stray light reduction. A tunnel magnetoresistance sensor (TMR sensor) is also included, which allows the lenses in the camera module to move with greater precision and stability. Finally, the guiding shaft motor has been upgraded, increasing the dynamic tilt at which the lens system can be moved. This makes continuous optical zoom at higher magnifications between 85mm and 200mm much easier to support.
Oppo claims that its new optical zoom technology eliminates issues like jumping, white balance inaccuracy, and color bias that can occur with traditional multi-camera zoom systems.
Optical image stabilization on five axes (OIS)
Oppo has announced the launch of its new Five-axis OIS, which allows the system processor to receive movement data from the gyroscope, analyze it, and break it down into its constituent parts using algorithms. The data is then passed to the two moveable components, the lens and the image sensor, which are both driven by ball-bearing motors and shape memory alloys.
Images are stabilized primarily through lens-shift OIS – which covers both horizontal (X) and vertical (Y) shifting – when the movement is relatively small. When the amplitude of the movement is relatively large, sensor-shift OIS – including horizontal shifting (x), vertical shifting (y), and rolling – will be used in conjunction with algorithm compensation to achieve five-axis space stabilization.
Oppo claims that its five-axis optical image stabilization system is three times better than traditional mobile phone technology. The company claims that it can help improve stability, clarity, and color performance, as well as increase vibration compensation performance by up to 65 percent in the night and motion shots.
Oppo’s algorithm and under-screen camera technology
Finally, the company unveiled its new under-screen camera technology. It makes use of transparent wiring and a new design to provide a much higher display quality and a more fluid visual experience. According to Oppo, the new algorithmic compensation technology precisely controls the chromaticity and brightness of the entire screen, with a deviation of only 2% and a 50% increase in screen lifespan.
A series of imaging AI algorithms have also been developed by the company’s research team. Diffraction reduction, anti-condensation, HDR, and Automatic White Balance are among them (AWB). The algorithms claim to improve the under-screen camera’s imaging quality.
