Image sensing is a critical element of a variety of modern technologies — automation, robotics, security systems, medical applications, drones, traffic cameras and driver assistance systems, are just a few examples where image sensing ensures that critical tasks are accomplished without a glitch. Image sensing has seen massive growth in recent years due to its increased application in vision systems for IoT. Embedding the right image sensor technology into IoT end nodes can drive greater accuracy in inspection, depth sensing, object recognition, and tracking.
