<p>PURPOSE:To enable a composition processing even when a generated area includes or overlaps with other areas by deciding the overlap of plural areas determined by an area generation part by an area determination part. CONSTITUTION:A command from an input deice 1 is decoded by the command decoding part 4 of a composition processor 3 and stored in a command decoded data storage part 5. A composition command processing part 6 performs the composition processing part according to the storage contents and the area generation part 10 of a processing execution part 10 determines an area where original data is to be displayed. Then the area decision part 14 decides the overlap of plural areas automatically. Then when there is the overlap, the processing part 6 divides an area which does not overlap and performs composition until no free area comes to exist, thus enabling the composition even when the generated area includes or overlaps with other areas.</p> |
