Method and apparatus for merging data and medium for providing program for merging data

An apparatus for merging a plurality of data, comprising:

• extracting means for extracting at least one of a high-frequency component of first data and a high-frequency component of second data;
• setting means for defining a synthesis area which includes a portion of the first data and a portion of the second data;
• and
• synthesizing means for determining a composite value of the first data and the second data in accordance with at least one of an amount of the high-frequency component of the first data and an amount of the high-frequency component of the second data, wherein the synthesizing means performs a synthesis process in the synthesis area.

A medium for providing a program for merging a plurality of data, the program comprising:

• an extracting step of extracting at least one of a high-frequency component of first data and a high-frequency component of second data;
• a setting step of defining a synthesis area which includes a portion of the first data and a portion of the second data;
• and
• a synthesizing step of determining a composite value of the first data and the second data in accordance with at least one of an amount of the high-frequency component of the first data and an amount of the high-frequency component of the second data, wherein the synthesizing step performs a synthesis process in the synthesis area.
