In this paper, we propose a macroblock-based weighted prediction method for multi view video coding. When local illumination change between pictures on the view/temporal directions occurs, the disparity/motion vectors cannot be accurately obtained. We found that bits for residual signal increases and coding efficiency is degraded. So, we propose the prediction method to cope with various illumination change in view/temporal direction. In our experimental results, our proposed method shows 0.1~0.4 ㏈ PSNR gains for various MVC test sequences, compared with JSVM 3.5 without the weighted prediction.
