摘要

PROBLEM TO BE SOLVED: To provide a movement detection method which detects accurate movement in short time and which can improve encoding efficiency. SOLUTION: A step for executing a full search block matching processing and obtaining data for residual (absolute residual sum) processing, a step for executing a residual processing and a step for generating data for residual processing are provided. The residual processing step has a step STg1 selecting a motion vector, a step STg2 setting an area by the selected motion vector and a step STg3 for matching full search blocks by using a setting area. The data generation step for residual processing has a step STh1 searching an inverse area by the obtained motion vector, a step STh2 calculating the addresses of all macro blocks in the inverse area, a step STh2 registering residual processing data, a step STh4 judging whether one screen is terminated or not, a step STh5 judging whether a scene is changed or not and a step STh6 judging whether the processings are terminated or not.
