ならないが、この処理は領域処理回路３において行われ
る。As shown in FIG. 2 (a), when the area is designated by two colors,
As shown in FIG. 2B, the area designated by the first area designation color 4 is detected as the area 40 indicated by the left diagonal hatching, and the area designated by the second area designation color 5 is the right. It is detected as a region 50 indicated by diagonal hatching. Therefore, in this case, the area specified by the one area specification color overlaps the area specified by the other area specification color, and it is necessary to decide which area to extract the overlapping area. This processing is performed in the area processing circuit 3.
本実施例では、予め領域指定色４に領域指定色５よりも

領域指定色４により指定された領域を優先的に取り出す
ようにしている。よって、第２図（ｃ）に示すように、
領域40が抽出されることになる。In this embodiment, the area designation color 4 is set to a higher priority than the area designation color 5 in advance, and the area processing circuit 3 preferentially extracts the area designated by the area designation color 4. Therefore, as shown in FIG. 2 (c),
Area 40 will be extracted.
第３図は優先順位を与えるための領域処理回路３の具体
