“The latest 3D image sensor from Infineon and pmdtechnologies enables a new generation of applications”, says Philipp von Schierstaedt, Senior Vice President Infineon Technologies AG. “It aims to create most immersive and smarter AR experiences as well as better photography results with a faster autofocus in low-light conditions or more beautiful night mode portraits based on picture segmentation. This latest chip development is truly setting standards when it comes to improvements of the imager, the driver and processing as well as unprecedented ten meters long range capabilities at lowest power.”

The new chip has been developed to easily integrate into miniaturized camera modules. It can accurately measure depth in short and long range for AR applications, while also offering a low power budget with over 40 percent lower power usage.

The new REAL3 ToF sensor offers a variety of configuration options to provide the flexibility to provide differentiated camera performance in a range of light conditions and use cases while prolonging the battery’s life in mobile devices. The new sensor makes it much simpler to implement applications with features such as real-time augmented reality, long-range scanning, small object reconstruction, fast low power autofocus and picture segmentation. Effects like background blur in videos and pictures from moving scenes can be easily enabled without the need for post-photography processing. These effects are easily implemented in all ambient light conditions.

The devices provide for high-quality 3D depth data capture up to a distance of ten meters, without a loss of resolution in the shorter range. This is ideal for seamless AR applications. Always-on applications, such as mobile AR gaming, also get the benefit of the low power draw required by the new sensor. Applications like 3D scanning for room and object reconstruction or 3D mapping for furniture planning benefit from the sensor’s ability for the doubling of the measuring range compared to current solutions on the market.

Demo kits are available now.
