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.

Executive Summary
• This full reverse costing study has been conducted to provide insight on technology data and
manufacturing cost of the Nokia Lumia 920 camera module.
• It is the first smartphone's camera module integrating an autofocus actuator with optical image
stabilization (OIS).
• The camera module is equipped with a 5-elements "floating lens" module which moves in
synchronization with the camera movement.
• The camera module integrates a 8.7 megapixel CMOS Image Sensor (CIS) from Sony. The CIS
features 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.

What's Surprising in this Device?
• The gyroscope integrating in the camera module is used to measure the camera movement (on two
axes, pitch and yaw), but also handles user-motion recognition (on three axes, roll/pitch/yaw), allowing
cost and board space savings of the phone. This two-in-one feature is possible due to the integration of a
dual-core 3-axis MEMS gyroscope supplied by STMicroelectronics.
• Compared to other smartphones which use "off-the-shelf" CMOS Image Sensors for resolutions of 8
megapixel and beyond, the camera module of the Nokia Lumia 920 employs a custom oversized 8.7
megapixel 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 for
low-end modules and Toshiba for high-end modules). This time, Nokia choose Sony for the CIS of the
Lumia 920.
