Smartphones To Capture High-Quality Images

Capturing image using Smartphones, Tablets, and Digital Still Cameras made simple with new multi-function motion sensor that handles gesture sensing and image stabilisation simultaneously. The newly launched iNEMOTM range of inertial motion sensors from ST is the industry’s lowest power consumption and smallest package size sensors, as claimed by the company.

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.

According to the press release, the LSM6DS3H sensor combines a 3-axis gyroscope, a 3-axis accelerometer, and an ultra-low-power processing circuit in a System-in-Package (SIP). The sensor leverage 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.

Adding further, these tiny, ultra-low-power MEMS module help manufacturers to minimise size, system complexity, and cost, while extending battery life in mobile imaging applications. The power consumed by sensor is less than 1mA, compared to the 5mA required by systems that employ two single-function gyroscopes, as stated in the release.

The release also mentions that LSM6DS3H is globally available which is priced at US$ 1.61 each, in 1000 unit quantities.

The key technical features of the LSM6DS3H include:

  • Ultra-low power consumption of the motion sensors (0.85mA in normal mode, 0.4mA in low power mode), allowing the gyroscope to be ‘always on’
  • Accelerometer power consumption in low-power mode down to 10 uA, 60 pr cent less compared with the previous-generation 6-axis module (LSM6DS3)
  • Supports both EIS and OIS applications with a choice of I2C or SPI for the primary interface and a dedicated auxiliary SPI interface to the camera module
  • Compact package measuring 2.5mm X 3mm X 0.83mm
  • Accelerometer ODR (Output Data Rate) up to 6.66kHz, Gyroscope ODR up to 3.33kHz
  • Smart FIFO for dynamic data batching and smarter power management: 4kbyte FIFO + 4kbyte flexible (FIFO or programmable)
  • Full-scale acceleration range +/- 2 / +/- 4 / +/- 8 / +/- 16g
  • Full-scale angular rate range +/- 125 / +/- 245 / +/- 500 / +/- 1000 / +/- 2000 dps
  • Supply voltage from 1.71V to 3.6V, independent IOs supply down to 1.62V
  • SPI/I2C serial interface data synchronization feature
  • Embedded temperature sensor
