The advantages over the lens-based OIS are:
- Not only camera yaw and pitch, but also roll is compensated
- Very fast sensor movements, under 15ms time required for image stabilization, said to be 3 times faster than lens-based OIS
- Power consumption as low as 10mW, said to be 50 times lower than lens-based OIS
- High accuracy of of compensation of 0.3um, while lens-based systems are said to be 10 times less accurate
"So why is the SmartSensor just now arriving? Let's have a look at just how difficult it was to bring about this technology.
To achieve three-axis sensor-based stabilization, the image sensor needs to be suspended in a very small space to allow for rotation around a central axis.
Another challenge brought by suspension is signal transmission. The SmartSensor presents the challenge of having to connect over 200 signal wires from the floating sensor to the main board.
This was the key puzzle that OPPO and MEMS Drive solved through years of research."
GSM Arena reports from the MWC 2016 Oppo booth: "Oppo SmartSensor image stabilization can correct up to 1.5° of motion and works on sensors ranging from 1/1.8" (bigger than any phone yet) and 1/3" (typical of mid-range phones). It's also smaller than a typical OIS module, so we may see it in thinner phones." While being a very impressive technology, 1.5deg is somewhat limited range for a high quality OIS.
Apparently, the company that supplied the technology to Oppo is MEMS Drive, based in Pasadena, CA.
