<p>THAT IS, A HIERARCHICAL CODING OF AN IMAGE DATA IS GENERATED. AN IMAGE DATA OF A SECOND HIERARCHY IS FORMED, HAVING A NUMBER OF PIXELS WHICH IS SMALLER THAN THAT OF AN IMAGE DATA OF A FIRST HIERARCHY. THE IMAGE DATA OF THE SECOND HIERARCHY IS CORRECTED TO GENERATE A CORRECTED DATA. THE IMAGE DATA OF THE FIRST HIERARCHY IS PREDICTED IN ACCORDANCE WITH THE CORRECTED DATA AND A PREDICTED DATA OF THE FIRST HIERARCHY, HAVING A PLURALITY OF PREDICTED PIXELS, IS GENERATED. PREDICTIVE ERROR OF THE PREDICTED DATA OF THE FIRST HIERARCHY IS CALCULATED WITH RESPECT TO THE IMAGE DATA OF THE FIRST HIERARCHY. THE SUITABILITY OF THE CORRECTED DATA IS DETERMINED IN ACCORDANCE WITH THE PREDICTED ERROR. A DIFFERENCE DATA, BETWEEN THE IMAGE DATA OF THE FIRST HIERARCHY AND THE PREDICTED DATA OF THE FIRST HIERARCHY, IS GENERATED IN ACCORDANCE WITH THE DETERMINED SUITABILITY. THE DIFFERENCE DATA HAS A PLURALITY OF DIFFERENCE VALUES. THE CORRECTED DATA AND THE DIFFERENCE DATA ARE OUTPUT AS THE CODED IMAGE DATA.FIGURE 5</p> |
