Abstract: A method and apparatus for using both D-FDMA and L-FDMA within a same frequency band is provided herein. The proposed technique scatters the sub-carriers of each D-FDMA user to a frequency band utilized by L-FDMA communications without separating the total band into exclusive D-FDMA and L-FDMA sub-bands. The L-FDMA users are assigned to the gap of the D-FDMA sub-carriers. Therefore, frequency diversity gain of D-FDMA by the proposed method is larger than if D-FDMA and L-FDMA sub-bands were created.

Abstract: An ? value in a desired shape in a desired position can be rewritten to a desired value in a desired range. ? value rewriting units for rewriting an ? value showing an opaqueness degree of an image are provided. When the desired position comes, an area setting signal is outputted in a desired shape from an area setting signal generating unit. While the area setting signal is being outputted, in the ? value rewriting unit, an ? value of inputted image data is rewritten to a desired value. The rewriting of the ? value can be dynamically realized independent of software. By preparing a quadrangular area calculating unit and a circular area calculating unit as an area setting signal generating unit, a quadrangular area and a circular area can be set by hardware.
