Further, in step S4, it is conceivable that the data of the secondary image for a plurality of pages can be obtained. In this case, the job control unit 41 causes the communication device 6 or the image forming device 2 to execute the image output process corresponding to all of the secondary images for a plurality of pages.

On the other hand, it is also conceivable that the color processing copy mode is selected as the operation mode. In this case, the job control unit 41 causes the image forming apparatus 2 to execute the printing process based on the data of the secondary image as the image output process. As a result, the secondary image is formed on the sheet 92.

As shown above, the color specifying unit 43 specifies the color of the color-designated image g1 included in the reference image g0 read from the reference document 9b by the scanning reader 1b as the designated color (S2).

Further, the image processing unit 44 performs predetermined processing on the designated color portion in the primary image read from the target document 9a by the fixed reading device 1f. As a result, the image processing unit 44 generates the data of the secondary image after processing (S4).

In the present application example, the job control unit 41 causes the document transport device 1d and the fixed scanning device 1f to sequentially read the images of the reference document 9b and the target document 9a on the document tray 1c in the color processing control.

Then, the color specifying unit 43 determines that a part of the plurality of documents 91 sequentially conveyed by the document conveying device 1d that satisfies the predetermined reference condition is the reference document 9b, and is conveyed following the reference document 9b. Others are determined to be the target manuscript 9a.

For example, it is conceivable that the color specifying unit 43 detects the predetermined specific mark M0 from the images read from each of the originals 91, thereby determining that the original 91 capable of detecting the specific mark M0 is the reference document 9b. Be done. In this case, the reference condition is that the image read from the document 91 includes the specific mark M0.

In this application example, it is conceivable that a plurality of documents 91 on the document tray 1c include a plurality of reference documents 9b and at least the same number of target documents 9a as the reference documents 9b. In this case, each time the color specifying unit 43 determines that the document 91 is the reference document 9b, the color specifying unit 43 uses the designated color as the color of the color-designated image g1 included in the image of the document 91 determined to be the reference document 9b. Update to.

Then, the image processing unit 44 executes the process of performing the designated processing on the updated portion of the designated color in the primary image read from the target document 9a, which is the subsequent document 91.

Even when this application example is adopted, even if the designated color to be image-processed differs depending on the content of the target document 9a, the designated color can be easily set.

[Fifth application example]
In the first embodiment or the second embodiment, it is conceivable that the target manuscript 9a and the reference manuscript 9b are stacked and placed on the manuscript tray 1c. In this case, the target manuscripts 9a are stacked on the manuscript tray 1c in the order in which the corresponding reference manuscripts 9b are read first.

In this application example, the color specifying unit 43 determines that the manuscript 91 conveyed in a predetermined order is the reference manuscript 9b, and determines that the other manuscript 91 is the target manuscript 9a. For example, it is conceivable that the predetermined order is the first page.
