Today, Time-of-Flight (ToF) systems are among the most innovative technologies offering imaging companies an opportunity to lead the market. Every major player wants to integrate these devices to provide functions such as 3D imaging, proximity sensing, ambient light sensing and gesture recognition. Sony / Softkinetic has been investigating this technology deeply, providing a unique pixel technology to several image sensor manufacturers in three application areas: consumer, automotive and industrial. For industrial applications, Sony/Softkinetic has licensed its technology to Texas Instruments, which is providing ToF imagers for human detection or robot-human interaction.
