Sharp’s 5G Smart Phone has video with background photo and video bokeh-effect
Uses Infineon REAL3™ 3D Image Sensor
February 19, 2020 Tokyo (Japan)
With the recent popularity of social networking services it has become common to shoot everyday photos and video and post them on the internet. One technique for efficiently and beautifully capturing images and video, and for making the subject stand out, is the so-called background bokeh-effect.
The Infineon Technologies REAL3™ 3D imaging sensor makes it possible to apply this bokeh-effect in real time on a smart phone, something which has been too difficult to do in the past, making it easy to shoot memorable images and videos. 3D depth sensors fill a critical role in applications that rely on precise 3D image data.
The REAL3™ 3D sensor is a joint development between Infineon Technologies AG and pmdtechnologies, a company with leading-edge specialized technology in software and 3D time-of-flight (ToF) systems. The sensor technology is used in Sharp’s AQUOS R5G smart phone, which goes on sale in Japan in spring, 2020.
Features of the REAL3™ 3D Image Sensor
Highly integrated for various integration: The Infineon 3D single-chip solution is highly integrated and therefore enables smallest ToF camera modules. It can be integrated into small smartphone handsets as well as for multiple applications such as face authentication, Virtual Reality/Augmented Reality and many more. Infineon and pmdtechnologies jointly developed this 3D imager as well as the corresponding algorithm to get a high precision 3D point cloud, which is necessary for such applications.
Uses a precise new measurement method: Previous 3D measurement technology used complex algorithms to compute the distance from the camera to the target object. The REAL3™ 3D Image Sensor is measuring the distance by capturing 940 nm infrared light reflected from the user and scanned objects and uses high-level data processing to achieve precise depth measurements. The needed compute power in the system is much lower, which enables use cases like video bokeh-effect which were not applicable before.
Resistant to sunlight, low power consumption: Patented SBI (suppression of background illumination) technology provides a wide dynamic range of measurement across any lighting situation, from bright sunlight to dimly lit rooms.
Sharp executive officer Yoshiro Nakano says: “Integrating Infineon's 3D image sensor in our smart phone allows for acquiring new information. We expect that applications making the most of distance and shape recognition will increase and that will extend a range of user experiences.”
“We’re very proud about the collaboration with Sharp on a smart phone going on sale in Japan that uses the Infineon REAL3™ 3D Image sensor.” said Andreas Urschitz, Infineon Power Management & Multimarket (PMM) division president. “We want to continue providing solid, highly reliable, energy efficient, and tiny chips to contribute to a wide range of applications. The 3D sensor has great chances for success, and we greatly hope that consumers will enjoy the beautiful new video camera effect it enables.”
The REAL3™ Image Sensor was developed in Graz, Austria, and Dresden and Siegen, Germany. For more information about Infineon’s 3D Image Sensor family products and usage, please see www.infineon.com/real3.
