A 1st control data to designate a contour of a photographic picture and a 2nd control data to synthesize the character picture and the photographic picture are stored in a control memory 17. A contour designation circuit 19 applies contour control to the photographic picture data (resolution 100dpi) in the memory 16 according to the 1st control data (resolution 100dpi) for designating contour in the memory 17. A selector 21 selects an output data in the memory 15 and an output data in the memory 16 and outputs the selected data according to the 2nd control data for controlling character/photograph synthesis in the memory 17. |
