摘要

AN ENCODING METHOD IN WHICH A PICTURE TYPE IS SEQUENTIALLY SET TO PICTURES OF INPUT IMAGE DATA (D1), THE INPUT IMAGE DATE IS ENCODED WHILE PREDICTING A GENERATED CODE QUANTITY OF EACH PICTURE, AND ENCODED DATA IS GENERATED, THE ENCODING METHOD INCLUDING THE STEPS OF: PREDICTING A ROUGHLY CALCULATED CODE QUANTITY OF THE ENCODED DATA GENERATED FROM THE INPUT IMAGE DATE (D1), AND OUTPUTTING THE ROUGHLY CALCULATED PREDICTED CODE QUANTITY; CALCULATING A TRUE PREDICTED CODE QUANTITY BY CORRECTING THE ROUGHLY CALCULATED PREDICTED CODE QUANTITY BY A CORRECTION COEFFICIENT CORRESPONDING TO THE PICTURE TYPE; ENCODING THE INPUT IMAGE DATA (D1) ON A BASIS OF THE TRUE PREDICTED CODE QUANTITY; AND SETTING THE CORRECTION COEFFICIENT OF THE CORRESPONDING PICTURE TYPE WITH DETECTING AN ACTUAL GENERATED CODE QUANTITY OF THE ENCODED DATA.
