description A video coding apparatus comprises a motion prediction unit configured to perform motion prediction for a plurality of coding unit sizes of an original image serving as the picture of an input video signal and evaluate results obtained by the motion prediction for the coding unit sizes so as to supply a first evaluation value; a merge mode evaluation unit configured to evaluate each of merge candidates on a coding unit of the merge size determined by a merge size determination unit so as to supply a second evaluation value of each of the merge candidates; and an inter-prediction mode determination unit configured to determine a mode used for coding on the basis of the second evaluation value obtained by the merge mode evaluation unit and the first evaluation value of the coding unit sizes.
