PURPOSE:To reproduce accurate original image pattern data by dividing the coordinate area of an original image pattern to be restored by the size of an original image pattern restoration coordinate area, setting a decision point which is required for the original image pattern restoration coordinate area for each divided coordinate area, and restoring the original image patterns divisionally. CONSTITUTION:When the original image pattern to be restored in the original image pattern restoration coordinate area 39 is wider than the restoration coordinate area 39, the coordinate area where contour points of contour point data are restored is divided to the size of the original image pattern restoration coordinate area 39. A decision point extracting means 38 sets an extracted coordinate point for each of divided coordinate areas and the original image patterns are restored divisionally to obtain the original image pattern data. Consequently, the accurate original image pattern data can be restored. |
