ABSTRACT:
Distance d1between the right edges of A1and B2, and distance d2between the right edges of A3and B4are calculated. If data to be embedded is 1, one or a combination of a process for increasing the size of B2in the column direction or decreasing the size of B4in the column and a process for moving the position of B2toward B3or moving the position of B4toward B3is executed to meet d1>d2. If data to be embedded is 0, one or a combination of a process for decreasing the size of B2in the column direction or increasing the size of B4in the column direction, and a process for moving the position of B2toward B1or moving the position of B4toward B5is executed to meet d1<d2.
