STMicroelectronics has introduced the world's most advanced six-axis motion-sensor, supporting image stabilisation in smartphones, tablets and digital still cameras. The latest addition to ST's iNEMO range of inertial motion sensors, the LSM6DS3H, combines a 3-axis gyroscope, a 3-axis accelerometer and an ULP processing IC in a SiP solution that offers industry-low power consumption and package size.

Electronic Image Stabilisation (EIS) and Optical Image Stabilisation (OIS) techniques help minimise image blurring caused by camera motion while the snapshot is being captured. Initially developed for professional cameras, these techniques are being increasingly deployed in smartphones and tablets, where blurring is most likely to occur when the user takes a photograph with an outstretched arm.

The LSM6DS3H builds on ST's expertise in designing high-end gyroscopes for OIS and the Company's pioneering role in providing dual-core gyroscopes capable of simultaneously handling both user motion and gesture recognition and camera image stabilisation. The tiny, ultra-low-power MEMS module allows equipment manufacturers to minimise size, system complexity, and cost, while extending battery life in mobile imaging applications, thanks to a power consumption of less than 1mA, compared to the 5mA required by systems that employ two single-function gyroscopes.

"Using smartphones to take photographs and videos at public or private events and sharing the results via social media has become an established part of our life. Very often people use the phone camera with outstretched arms, which can degrade the image quality," said Andrea Onetti, General Manager, Volume MEMS and Analogue Division, STMicroelectronics. "Our multi-function motion sensor sets to minimise blurring in any photo situation while extending battery life because of the ultra-low power consumption."

The LSM6DS3H is available now in volume production at a price of $1.61 in quantities of 1,000 units.
