[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing apparatus and an image editing method for designating an arbitrary area on a document and performing processing such as extraction and deletion.

[0002]

2. Description of the Related Art For example, various image processing apparatuses are capable of extracting only an image of a desired area from an original image without cutting and pasting the original, or editing an image in which only the image of the area is erased. Is required. In response to this request, Japanese Patent Laid-Open No. 62-159570 discloses a trimming mode in which an area is extracted by editing an image by specifying an arbitrary area of the original image using a marker on the original, and the area. An image processing device for editing is disclosed. Further, Japanese Patent Application Laid-Open No. 63-43944 discloses an image editing apparatus having area setting means using a memory.

[0003]

By the way, in the former case of the above-mentioned prior art, when a marker is designated on a document, if the information such as characters on the document is the same as or very close to the density of the marker, the marker area can be detected accurately. I can't do it. In addition, the marker itself remains on the document, and the reusability is poor. Furthermore, even if the marker area is accurately detected, if density correction is performed to prevent the marker from being output on the copy, information with low density of the document information may not be output on the copy, or the other way around. If the density is corrected, the marker is output on the copy and is not stable.

In order to solve this, it is possible to copy the original once and specify a mark on the copy.
In this case, since the copy is a generation copy, the quality of the output image based on this copy deteriorates.

The latter is a method for solving these problems.
In the latter case, similarly to the case where the original image is read and stored in the storage unit, a copy output is performed, a marker is designated in the copy output and read again, marker area detection processing is performed, and at the same time, the original image is stored in the storage unit. The information is read and only the image information inside or outside the area detected by the marker area detection processing is output as an image as an edited result. In this case, if you want to change the processing method of the area designated by the marker, or the original If the specified area is misaligned due to the set position deviation, etc., and the desired information is missing, specify the processing method again or correct the document setting position and specify the marker. It is necessary to perform the reading operation of the copied original,
Even so, if there was a gap in the area, it would have to be redone and it would be annoying.

The present invention has been made in view of the above-mentioned problems of the prior art, and has been made in order to solve this problem. An object of the present invention is to read by reinserting a document or refill a marker area even if a designated area is displaced. An object of the present invention is to provide an image editing apparatus and an image editing method that can easily obtain a desired edited image without requiring an operation such as re-insertion by.

[0007]

By calculating the sum,
The edited image shown in is obtained.

By the way, in the embodiment, as described above,
It is necessary to read each of the two originals at the time of image editing, but there is a variation in the reading position accuracy of the reading device, and there is a quality of the designated position when writing in the area designation. Area is not always extracted. For example, if the extraction area shifts upward,
If the upper part of the extracted image is missing as shown in (a) and the extracted region is shifted to the right, the left part of the extracted image will be missing as shown in FIG. 4 (b). As described above, conventionally, in such a case, it is necessary to redo the image editing from the beginning, and the correction work of the image editing has been very complicated.

In the embodiment, by inputting the correction direction and the correction amount on the operation display device 4 and operating the re-editing key, the image editing can be easily corrected. For example, when the upper part of the designated area is missing by 2 mm as shown in FIG. 4A, the area correction key 16 of the operation display device 4 shown in FIG. While inputting, the display unit 19 is monitored and the direction and the correction amount set by the input of the key 18 are set so as to satisfy a predetermined condition (upward 2 mm). When the re-editing key 17 is pressed after the correction is set under a predetermined condition, a re-editing command is input from the system control device 5 to the edit control device 14 of the image editing device 2 and the recording device 3. A correction signal indicating the correction direction and the correction amount is also input to 14.

With this correction signal, the editing control device 14 causes the sub-operation address management circuit 11 of the second storage means 9 to send an address value corresponding to 2 mm to the sub-operation address management circuit 11 of the second storage means 9 in step S9 of the flowchart shown in FIG. (Ad)
Is set, and the correction direction is confirmed in step S10. In this case, since the correction is performed upward, it is confirmed that the correction value is set to 2 mm upward in step S11. After this setting, the process proceeds to step S15, and reading from the first storage means 6 and the second storage means 9 is started at the same time.
By this reading, the image information RVD1 is read from the first storage means 6 from the leading edge of the original image, and the area information RVD2 is read from the second storage means 9 to the upper side.
It is read from the position shifted by mm.

Next, in step S16, it is determined whether the conversion processing is additional processing. In this case, since the conversion processing is conversion processing, the image information RVD1 and the second information read from the first storage means 6 in step S17. The logical product with the area information RVD2 read from the storage means 6 is calculated.
In this way, the upper chip is corrected and an edited image as shown in FIG. 3C is obtained. If the correction direction is upward, leftward, or rightward, the process proceeds to step 15 through steps S12, S13, and S14 in the flowchart of FIG. 8, and if additional processing is performed, the process proceeds to step S18 to perform additional calculation. Be done.

As described above, according to the above-described embodiment, since the area is designated by the marker and the image is edited, the density of the marker can be freely selected and the original is not marked.
It is possible to reuse the manuscript. Further, when a shift occurs in the edited image, the shift can be easily corrected by using the key 18 of the operation display device 4 to set the correction direction and the rational charge without redone image editing again. be able to.

In the above embodiment, the case where the area information is shifted to correct the positional deviation of the edited image has been described, but the present invention is not limited to the embodiment, and the image information is shifted to edit the edited image. It is also possible to correct the position shift of.

[0022]

As described above, according to the present invention,
