Tango-ready Lenovo Smartphone Uses Tiny 3D camera for Augmented Reality
Based on the Time-of-Flight principle, the REAL3 image sensor from Infineon Technologies (Germany) equips the new Lenovo (Hong Kong) PHAB2 Pro smartphone with a 3-dimensional perception of the surroundings in real-time. Its users have instant access to AR (Augmented Reality) TANGO technology, benefiting from the phone’s motion tracking feature which responds to physical movements, depth perception that measures the distance between objects and area learning capability which enables the device to recall the data recorded from previously visited locations.
The Real3 Sensor
The sensor chip was developed in Graz, Austria, a global Infineon competence center for advanced semiconductor solutions combining analog and digital signal processing with high data rates. It integrates the pixel array, the control circuitry, ADCs and the digital high-speed interface on a single chip. The development was made in co-operation with pmdtechnologies, a worldwide leading provider of the Time-of-Flight (ToF) technology.
This measuring principle involves infrared light. For each of its pixels, the 3D image sensor chip measures the time the light takes to travel from the camera to the object and back again. Each pixel detects the brightness value of the objects. Compared to other technologies, the ToF technology from pmdtechnologies offers the best spatial resolution and highest robustness both mechanically and concerning background light. Yet, it has the lowest current consumption and size. Thus, the camera is currently the smallest 3D-camera worldwide.
Infineon Technologies AG is a world leader in semiconductor solutions that make life easier, safer and greener. Microelectronics from Infineon is the key to a better future. In the 2015 fiscal year (ending September 30), the company reported sales of about Euro 5.8 billion with some 35,400 employees worldwide.
