Nokia Lumia 920 Camera Module with OIS

The first smartphone's camera module integrating Optical Image Stabilization (OIS) realized with a dual-core 3-axis MEMS gyroscope and a floating lens technology

While Digital Still Cameras commonly use optical image stabilization, it was not included in smartphones. The Nokia Lumia 920 is the first smartphone featuring an OIS function.

To performs Optical Image Stabilization, the camera module includes a floating lens technology which consists in moving the 5-elements lens module in perfect synchronization with the camera movement.

Nokia Lumia 920 – Camera Module with OIS 3Executive Summary• This full reverse costing study has been conducted to provide insight on technology data andmanufacturing cost of the Nokia Lumia 920 camera module.• It is the first smartphones camera module integrating an autofocus actuator with optical imagestabilization (OIS).• The camera module is equipped with a 5-elements "floating lens" module which moves insynchronization with the camera movement.• The camera module integrates a 8.7 megapixel CMOS Image Sensor (CIS) from Sony. The CISfeatures a 1.4µm pixel size and uses a Back-Side Illuminated (BSI) technology.• The camera module is provided in a 12.5mm x 12.5mm x 6.00mm package.• We estimate that Nokia is the prime contractor.
  • 4. © 2013 by SYSTEM PLUS CONSULTING, all rights reserved. Nokia Lumia 920 – Camera Module with OIS 4Whats Surprising in this Device?• The gyroscope integrating in the camera module is used to measure the camera movement (on twoaxes, pitch and yaw), but also handles user-motion recognition (on three axes, roll/pitch/yaw), allowingcost and board space savings of the phone. This two-in-one feature is possible due to the integration of adual-core 3-axis MEMS gyroscope supplied by STMicroelectronics.• Compared to other smartphones which use "off-the-shelf" CMOS Image Sensors for resolutions of 8megapixel and beyond, the camera module of the Nokia Lumia 920 employs a custom oversized 8.7megapixel CIS able to provide true 16:9 and 4:3 formatted aspect ratios.• Most of Nokia previous camera modules used STMicroelectronics and Toshiba as CIS suppliers (ST forlow-end modules and Toshiba for high-end modules). This time, Nokia choose Sony for the CIS of theLumia 920.
