In this paper, we propose a synthesized views distortion model based rate control algorithm for the high efficiency video coding HEVC based 3D video compression standard. The major contributions of the paper include the following two aspects. Firstly, we investigate the distortion dependency between the synthesized views and the coded views including texture video and depth maps. Then we propose a synthesized views distortion model for 3D-HEVC, and based on the distortion model an efficient joint bit allocation scheme is proposed. Experimental results show that the proposed rate control algorithm achieves better performance on both the coded texture views and synthesized views. The maximum overall including all coded texture views and all synthesized views performance improvement can be up to 14.4i¾ź% and the average BD-rate gain is 6.9i¾ź%. Moreover, it can accurately control the bitrate to satisfy the total bitrate constraint.
