An LED-based BLU architecture has enabled local dimming, which can produce higher power saving than global dimming in LCD-based devices. However, existing local dimming techniques have not considered human visual system-awareness much. In this paper, we propose a novel local dimming technique using an object-based approach for both good human visuality and high power saving. We utilize prevalent colors of individual objects in a given image to do initial dimming, and then enhance the image using a proper fidelity threshold to reduce visible artifacts. Experimental results show that the proposed technique achieves power saving up to 12 and 5.5 times higher than a prior human visual system-aware global dimming approach and a well-designed local dimming one, respectively. |
