| Abstract: |
Reducing LCD backlight can save power consumption of a portable device, but it also decreases the contrast and brightness of the images. Previous approaches adjust the backlight level frame by frame to reach a specified image quality level but do not optimize it. On the contrary, the proposed method adjusts the backlight to meet the target power level while maintaining the image quality. This is achieved by incorporating brightness compensation and local contrast enhancement depending on the given backlight level. Experimental results show that the proposed algorithm outperforms previous methods. |
