Intelligent ICU Video Disp lay for Multi-Intensity IR Illumination

Abstract

An Intelligent ICU Video Display System for monitoring patients at nighttime is proposed for the next generation ICU environment, wherein infrared light is employed in place of the visible one. However, for simple system with a single light source, patients at different locations may not be illuminated properly due to overexposure/underexposure. To resolve such a problem, a novel IR illuminator is proposed which can emit periodically varying intensity of IR light toward the patients. An effective monitoring system can then be established with multi-channel display of videos of different dynamic range for a single camera. Hopefully our innovation will greatly benefit the ICU healthcare system.
