Device) 21.
The image data input to the special area extraction data editing unit 15 is compared by the image comparison circuit 16 with the specific pattern stored in the specific pattern storage memory 17 and the input image data. Recognize
The area determination circuit 18 recognizes the data area of the specific area to be edited by the image data editing circuit 19. The image data editing circuit 19 outputs the data in the specific area without editing during normal printing in accordance with the instruction of the printing mode switching means 20.

When the instruction of the print mode switching means 20 is erasure, data in which the data in the specific area is set to the null state is output. When the instruction of the printing mode switching means 20 is special, data obtained by adding editing such as color tone correction and shading correction to the data in the specific area is output.
The specific pattern file can have a function of editing from an external personal computer (external device), and can also be added from input image data from a digital copying machine. For this reason, a display device for displaying the contents and displaying the display selection screen 21 on which the use can be selected is attached to the copying machine main body.
As described above, since the digital copying machine main body has the specific pattern file selection display screen, the contents can be easily confirmed, and the pattern file can be easily selected and changed.

According to the present invention, the specific pattern adding means for adding the specific pattern from the input image data from the digital copying machine to the specific pattern file recorded in the specific pattern storage memory 17 is provided.
According to such a configuration, it is possible to add a specific pattern from the input image data from the digital copying machine to the specific pattern file recorded in the specific pattern storage memory 17, so that more various specific patterns can be used. Is possible.
Further, the digital copying machine A according to the present invention records the edited image data in the area in the external recording medium drive 22 so that the data after editing the presentation material on the paper medium can be electronically stored as necessary. Can be saved and re-edited as a file.

FIG. 3 is a flowchart for explaining the data flow in the specific area extraction data editing unit. Referring to FIGS. 2 and 3, image data is input to image comparison circuit 16 of specific area extraction data editing unit 15 (S1).
The specific pattern stored in the specific pattern storage memory 17 is input to the image comparison circuit 16 (S2). The specific pattern stored in the specific pattern storage memory 17 is compared with the image data to recognize whether the specific pattern exists and where it exists (S3).
If the specific pattern exists, the area determination circuit 18 recognizes the data area of the specific area to be edited by the image data editing circuit 19 (S4). The image data editing circuit 19 selects and outputs the output data in accordance with the instruction from the print mode switching means 20 (S5).
The print mode switching mechanism 20 has the following three instructions. That is, during normal printing (S6), the data in the specific area is output without being edited. When the instruction of the print mode switching means 20 is erasure (S7), data obtained by setting the data in the specific area to the null state is output.
When the instruction of the print mode switching means 20 is special (S8), data obtained by editing the specific area data, such as color tone correction and shading correction, is output. Therefore, printing is performed for each mode (S9).

FIG. 4 is a diagram showing an example of a specific pattern used in the present invention. FIG. 5 is a diagram showing an example of area specification of a specific area pattern to be recognized. FIG. 6 is a diagram showing printing results for each mode.
When the specific area extraction data editing unit 15 (FIG. 2) is installed in the digital copying machine A (FIG. 1), the specific pattern storage memory 17 (FIG. 1) stores characters, symbols, and lines as shown in FIG. , A specific pattern consisting of shading, texture, gradation, etc. is stored.
This makes it possible to recognize (a) to (f) of the specific area pattern shown in FIG. FIG. 5A shows another print portion 23a and a specific area pattern 23b surrounded by a line. FIG. 5B shows another print portion 23a and a specific area pattern 23b surrounded by characters.
