Research Abstract

We have studied fundamental technologies for security cloths, which detect and alert to potential dangers in the surroundings, based on thin and compact compound-eye imaging systems using image sensor technologies. We designed a low-voltage and low-power-dissipation CMOS image sensors with pulse-width-modulation photosensors and built-in micro-controllers. We also developed a smooth and edge-preserving depth estimation scheme from the distributed images captured by the compound-eye ultra-compact cameras.
