On an average television utilization per day is around 5 hours and it almost costs around Rs. 50 per day. Sometimes the television will running idle without any viewer. The objective of this idea is to reduce this wastage of television power consumption. Method: In this idea, we used face detection and eye ball detection using image processing for automatic television turn ON and turn OFF by using camera for detecting the viewer. The pupil detection in open CV software is used for our problem. The camera detects the face and then detects eye ball and continuously monitors the movement of eye ball. When the face and pupil is detected continuously for some time, by using a relay camera makes television unit ON and camera makes television unit OFF when pupil is not detected. This is developed for efficient utilization of television power.

INTRODUCTION Television is the medium for transmission of moving images in monochrome or color, in 2D or 3D with sound. In 1920s black & white televisions were started but were popular after the world war-II. In 1960s, color televisions has started and evolved to digital television in late 1990s. Now a days, high definition & smart TVs were emerging with advanced features.Many times power of a television is wasted when a viewer is sleeping without switching off the TV or forgets to switch off and left the room. This cannot be understood by a television to go into sleep mode, so the TV will be running and wasting the power of a television set. The aim of this paper is to make television smart enough to understand whether the viewer is available and viewing or not. If no person is viewing the television and it is idle, the camera will identify and turn-off the television set. If viewer is available before TV, then it will be turned ON without any intervention of the viewer. By using face detection [1] & eye ball detection [1, 2, 3], the system identifies the viewer and his eye ball for some time interval and then takes a decision whether viewer is available.
