Improved Contrast Ratio of the Camera Image on the LCD by using Double-exposure Image processing Method

In this paper, we propose the improvement method of the camera images on the liquid crystal display (LCD) regardless of exposure environments. By using a double-exposure method, we could improve camera images with clear recognition. We applied the improvement method on the LCD panel of the mobile phone because LCD is mainly applied to the display device of portable electronic devices. For the,feasibility of the proposed algorithm, we compared simulated camera images with the proposed method to conventional images on the LCD panel. Experimental results are also shown in this paper.
