1. the bit rate control method merging vision perception characteristic, it is characterised in that comprise the following steps:

  • The first step;

    carry out GOP layer bit rate and control to initialize;

    Second step;

    carry out frame layer rate control initialization, it is judged that present frame fnWhether is I frame, the most then coding I frame, then entersEnter the 7th step;

    If it is not, then enter the 3rd step;

    3rd step;

    first, according to present frame fnLuminance component and reference frame fn-1Luminance component, calculate in present frame eachThe luminance mean value of LCUWherein, N is the number of LCU in current encoded frame, and then calculates in present frameThe brightness impression right to know weight L of each LCUi(i=0,1,2L N-1);
