Abstract
In this paper, we propose an improved dynamic gamma correction method to enhance contrast and image quality for Liquid Crystal Displays (LCD) with Multi-Phosphor White Light Emitting Diodes (MPW LED). In order to reduce the hardware cost and improve the contrast and the edge strength, the proposed gamma correction method uses content-based analysis to reduce computational complexity. Experimental results demonstrate that the proposed gamma correction method has better visual assessment. Absolute Mean Brightness Error (AMBE), contrast enhancement, and similar Edge Loss Rate (ELR) quality are superior to the traditional methods.
