摘要
The present invention in selecting the prediction mode and block size of video coding, there is provided a prediction mode costing method that can further reduce the visual degradation. The invention relates to a prediction mode cost calculation method used for the prediction mode selected for the video coding, it is divided into a predetermined small area of the residual of the prediction block, and calculates a prediction residual power was the small areas each divided a small region prediction residual power calculation step, and the penalty calculation step of calculating a penalty value based on the value that is determined based on the calculated small region prediction residual power is added to the prediction mode costs the calculated penalty values last for I and a prediction mode cost calculation step of calculating a prediction modes cost.BACKGROUND 1
