ABSTRACT:
A scene adaptive power control device using a plurality of input images as consecutive input images and controlling a power level of a light source used in displaying the third input image. The scene adaptive power control device including a histogram analysis unit to analyze the second input image and detect a first maximum brightness value of the second input image, a determination unit to detect brightness values matching a first threshold as a predetermined frequency value in the generated histogram and determining a second maximum brightness value, a generation unit generating a power control signal to control the power level of the light source by a value obtained by dividing the second maximum brightness value by the first maximum brightness value, and a compensation unit increasing a brightness of the third input image inversely proportional to the power level of the light source reduced by the power control signal.
