摘要：In this paper, we present a smart image sensor with high-speed and low-intensity ID beacon detection for an augmented reality (AR) system. AR systems are designed to provide an enhanced view of the real world with meaningful information on a computer. Our target AR system uses an optical device with an ID beacon such as a blinking LED. Our sensor architecture simultaneously achieves analog readout for 2-D image capture and high-speed digital readout for ID beacon detection. The pixel circuit has a logarithmic-response photo detector and an adaptivemodulation amplifier to detect the low-intensity ID beacon with a wide range of background illumination. We developed and successfully tested a 128x128 smart sensor. It achieves 20 bytes/ID-frame with a 40 kHz carrier at 30 fps, and less than-10.0 dB signal-to-background ratio (SBR) with more than 40 dB background illumination in robust ID-beacon detection.
