Infineon Technologies AG is presenting the fourth generation of its REAL3™ image sensor IRS2771C at Mobile World Congress 2019 in Barcelona, Spain. The 3D Time-of-Flight (ToF) single chip is especially designed to meet the demand for higher resolutions with small lenses.
The wide range of use cases includes secure user authentication like face or hand recognition to unlock the device and confirm payments. In addition, the 3D ToF chip enhances augmented reality, morphing and photo (e.g. bokeh) effects and can be used to scan a room.
Measuring only 4.6 x 5 mm, the image sensor features a 150 k (448 x 336) pixel output that comes close to the HVGA standard resolution. This makes the resolution four times higher than that of most ToF solutions on the market today. The pixel array is highly sensitive to 940 nm infrared light. Uutdoor performance is improved by the patented Suppression of Background Illumination (SBI) circuitry in every pixel. Due to its high level of integration, each IRS2771C image sensor is essentially a miniature single-chip ToF camera. This dramatically reduces the overall bill of materials and the actual size of the camera module without compromising on performance and keeping power consumption to a minimum.
