Oppo introduces Super VOOC tech that charges smartphones in 15 minutes, sensor-based image stabilisation

Oppo explained that such technologies's underlying principles are actually quite different from Super VOOC's. Whereas they apply high-voltage fast-charging, Super VOOC Flash Charge relies on a low voltage of 5 volts, staying within standard voltage and temperature levels for smartphone charging and ensuring safety in the long run. This also eliminates the need for a voltage converter, making for a more efficient charging process.

Moreover, Super VOOC's low-voltage charging allows for fast-charging your smartphone while using it. Other fast charging technologies revert to a standard charging speed while the handset is in use, due to temperature spikes caused by the simultaneous quick charging and screen brightening.

Oppo's Super VOOC tech is proprietary and unless they license it to other manufacturers, it will be a mainstay of its own smartphones. The company can pull off its fast charging magic off thanks to an all-new low-voltage pulse-charge system, in combination with a customized battery. The system uses a new algorithm to dynamically regulate the current, ensuring the fastest charging time possible while maintaining current within the battery's safe range. To complete its solution, Oppo redesigned the Super VOOC Flash Charge adapter, cable, and connector with military-grade materials to make them reliable and rugged.

Besides Super VOOC, OPPO showcased a proprietary image stabilization technology called SmartSenor. This is supposed to be a first in world pixel-level OIS (Optical Image Stabilisation) solution. SmartSensor employs a sensor-based 3-axis stabiliser, while most (though not all) lens and motor-based solutions are 2-axis and usually implemented in flagship smartphones only. Oppo's tech takes just 15 milliseconds to achieve "comprehensive" image stabilisation for blur-free shots and shake-less video. According to their expertise, traditional lens-based stabilizers take at least 50 milliseconds to react to camera movements, which means Oppo's solution is about three times faster. It's also touted as more practical and being able to compensate for a greater range of motion.

Moreover, SmartSensor is said to greatly reduce power consumption, which helps avoid lens heating. Traditional lens-based image stabilization modules use an electrically powered voice coil motor, which consumes over 500mW of power with each photo, and quickly heats up when taking photos for extended periods of time, which impacts lens performance and lowers image quality. SmartSensor uses a voltage-driven sensor, which reduces electricity consumption to as low as 10 milliwatts.

Oppo also talked up the SmartSensor’s precision. Traditional lens-based technologies have a precision of 3 to 5 micrometers, while SmartSensor remains precise to a vibration of just 0.3 micrometers. One pixel is about 1 micrometer, which means that SmartSensor makes precise adjustments at scales of less than a third of a pixel. This is why Oppo touts its tech as capable of pixel-level image stabilization.

OPPO did not reveal which smartphones will carry its latest technologies, but they could become staple features of its upcoming, and long in the making Find 9 flagship smartphone. The company is taking its technological research seriously, coming up with ways to make our smartphones even more awesome than they are now.
