Abstract
- In this paper, three types of algorithms for LED-TFT -LCD displays' content-aware management are presented. Their aim is to minimize the power consumption of the displays, while simultaneously preserving the quality of the displayed content, utilizing global backlight dimming. The first category of algorithms is developed based on proper camera measurements, while the second is developed via lightmeter measurements. The third category is formed by combining the strengths of the previous two. In contrast to previous approach, these algorithms take into account the different contribution of basic colors to the overall image illuminance and adjust accordingly to accomplish greater resemblance between the original and the processed image. The algorithms were tested assuming various pictures with different color patterns. Our experimental results reveal that a 30% power reduction can be achieved with less than 10% average image distortion.
