Abstract:
In order to realize the energy saving of the backlight in liquid crystal display (LCD) with approximate image quality,a human visual characteristics guided backlight luminance scaling method is proposed for power minimization. Image histogram clipping and extension steps are firstly established based on the luminance consistency theory. Dark and bright regions of the image are weighted respectively based on the human visual threshold property and then the histogram is clipped to the restricted range. To com...
