(c) Shutterstock - It is the first smart image sensor jointly featuring auto-exposure for all lighting conditions and 88dB dynamic range, as well as motion detection and feature extraction for event-based functioning, and AI-based object recognition that triggers highly reliable identification. These key features also enable highly reliable decision taking for a few tens of pJ/pixel/frame, which outperforms existing off-the-shelf systems. The pJ/pixel/frame measures the energy spent by each pixel for each single image within a frame of images. A typical implementation requires about 10,000 more energy than µWAI. The autonomous imager is the world's first highly efficient, compact and ultralow-power, smart-awaken system designed for everyday small appliances. It also includes: - Energy efficiency: consuming 10k less than low-power camera plus processor set, - Privacy-compliant, AI-based recognition: nearly human-detection performance (95 percent), - Wide operating lighting sensitivity to ensure accurate recognition in extremely variable conditions, Five-year, always-on CR1025 battery lifetime - 3-6µW operation, which is required for the Internet of Things and can work with a button cell that lasts five years. CEA-Leti's team is working hand-in-hand with an industrial partner to develop specific smart-imager products as we consider extending the technology to other use cases by adapting the recognition engine as IP embedded in various cameras," said Antoine Dupret, industrial partnership manager.
