Choong Geun Lee, Vasily G. Moshnyaga, Koji Hashimoto · 2011
This paper presents a simple yet efficient implementation of a camera-based viewer monitoring in system for reducing power consumption of television set. The system keeps TV screen active only if someone is watching it. When nobody is present in front of the camera, the TV is dimmed to save power while keeping the audio ON. Experiments show that the system can reduce the TV power consumption significantly especially when TV set is left ON unwatched.
