Abstract
Energy consumption in Organic Light Emitting
Diode (OLED) depends on the displayed contents. The power
consumed by an OLED-based display is directly proportional to
the luminance of the image pixels. In this paper, a novel idea
is proposed to generate energy-efficient images, which consume
less power when shown on an OLED-based display. The Blue
color component of an image pixel is the most power-hungry
i.e. it consumes more power as compared to the Red and Green
color components. The main idea is to reduce the intensity of
the blue color to the best possible level so that the overall power
consumption is reduced while maintaining the perceptual quality
of an image. The idea is inspired by the famous “Land Effect”,
which demonstrates that it is possible to generate a full-color
image by using only two color components instead of three.
experiments are performed on the Kodak image database. The
results show that the proposed method is able to reduce the power
consumption by 18% on average and the modified images do not
lose the perceptual quality. Social media platform, where users
scroll over many images, is an ideal application for the proposed
method since it will greatly reduce the power consumption in
mobile phones during surfing social networking applications
