Recently, camera modules in smartphones have evolved rapidly. All major players have adopted dual cameras. Now, with the Phab2Pro, Lenovo is the first to choose a different approach. As augmented reality plays a bigger part in consumer life, Lenovo is integrating a 3D Time-of-Flight (ToF) camera. The module features three cameras: one with high resolution, a global shutter motion detector and a Near Infra-Red (NIR) sensor.

The Lenovo Phab2Pro brings totally new functionality based on the Google Tango Project. This project, a collaboration including Infineon, pmd and Sunny Optical, has developed 3D ToF sensors for consumer applications.

The Phab2Pro implements this technology using a tri-camera sensor. The subsystem features a 16 megapixel resolution CMOS image sensor (CIS) from Samsung, a VGA resolution CIS with global shutter technology from Omnivision, and a 38 kilopixel resolution 3D Image Sensor from the collaboration between Infineon and pmd integrated into a subsystem with a NIR vertical-cavity surface-emitting laser (VCSEL).

To provide the 3D scene, the tri-camera’s high-resolution camera supplies the texture and the global shutter camera supplies the motion-tracking. Finally, the ToF sensor supplies the depth perception at a high rate thanks to the VCSEL emitter, which gives the phone the ability to understand space and motion quickly, like a human.

The report includes technology and cost analysis of the 3D ToF sensor and technology analyses of the two other modules. These analyses provide the technical intelligence necessary to understand this technology.
