摘　　要：目前的视频节能算法在降低能耗的同时难以保证视频的保真度,为此,提出一种具有视频保真特性的有机发光二极管(Organic Light-Emitting Diode, OLED)屏幕节能算法。结合人眼的视觉特性,通过降低蓝色分量强度来减少像素的能耗;颜色处理过程中,根据个体对色彩感知的差异,通过获取的观看反馈来动态调整色差阈值,达到节能和保真的平衡。实验结果表明,在保证视频保真度的同时,采用该算法可降低8.1%的屏幕能耗。With the popularity of smartphones and video applications,the power consumption of screen has become an important constraint factor.Current energy-saving algorithms for video applications cannot effectively keep balance between energy saving and video fidelity.This paper proposes an energy-saving algorithm based on visual characteristics,which reduces screen power consumption by dynamically adjusting the chromatic aberration threshold,while the processed video maintains high fidelity.Experimental results show that the proposed screen energy-saving algorithm reduces the screen power consumption by about 8.1%while ensuring the high fidelity of the video.
