BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing apparatus, such as a digital copying machine or a printer, which digitally processes image information to edit and copy the image.

[0002]

2. Description of the Related Art A conventional digital copying machine has an editing function for editing a required portion by moving a designated portion using an editor board. Further, as another method, there is one having an edit function of moving an image by directly marking an original with a marker pen and further marking a moving destination on the original. In this method, a marker pen that is read lighter than the image density on the original is used to directly mark the original, and the range is specified to perform processing and editing using the marker range specification.

[0003]

In the case of a manuscript full of gaps, if this manuscript is copied, a blank portion without information will be copied together. As a result, the blank portion of the transfer paper was wasted. Further, in the case of the above-mentioned original, the blank space portion can be used as a memo writing space, but if the blank space is in a dispersed position, it may be difficult to use when trying to write a memo.

In order to eliminate the above waste, it is possible to eliminate the waste of transfer paper by preparing a special editing device (editor board) as described above and moving a designated portion. Was expensive, the precision of region designation was poor, and complicated region designation was impossible.

If the editing function using the marker as described above is used as an inexpensive editing function, the image can be processed and edited without requiring a special editing function, but the original is directly marked. It had to be done, so it had the drawback of making the manuscript dirty. Therefore, in order to prevent the original from becoming dirty, a method has been taken in which the original is copied once, and the copy is marked and processed and edited. However, in this case, there are drawbacks that the image quality is deteriorated because copying is performed over two generations until the final copy is obtained for the original, and it becomes a grandchild copy, and the marker range designation is 1 It was designated only in the place.

An object of the present invention is to delete a portion of an original document on which no image information is recorded, reduce the amount of wasted transfer paper, or make an effective use of a blank paper image editing apparatus. To provide.

FIG. 8 is a flow chart showing an example of processing contents in the blank sheet portion deletion mode. This flow is CP
The processing operation of U13 is shown. First, when the power is turned on, the processing mode and the like are initialized (S1). Next, the original is placed on the contact glass 21, and the editing and contents are input from the operation unit 3 (S2), and the start instruction is waited (S3). When the start instruction is given, the contents of the method of handling the blank portion are confirmed (S4). If the blank sheet partial shift mode is not set, the process proceeds to S5. If it is set, the size of the blank image portion to be deleted, the shift direction, etc. are confirmed.

Next, the image editing apparatus activates the scanner section 1 to read an image (S5). The read image data passes through the I / F 12 and the image memory 9, 1
It is stored in 0 (S6). After this, the image memories 9 and 10
The image data stored in is edited and processed based on the result of the editing content designated in advance (S7).

Next, when the automatic change setting of the size of the transfer paper after cutting (ecology mode) is set, the optimum transfer paper size is determined from the overall image size after processing / editing (S8, S9). , I / F the contents of the image memories 9 and 10
The data is returned to the IPU 5 side through 12 and output by the printer unit 2 (S10). Then, on the flowchart, the state returns to the state after the initialization, and the state is in the state of waiting for the input instruction from the operation unit 3. In the present embodiment, all image editing is performed by software processing by the CPU 13, but processing may be performed by dedicated hardware for image editing.

Next, the individual contents of each step will be described. First, the confirmation of how to deal with blank pages will be described. In S4, the content of processing for the blank image portion set in S1 is confirmed. In this embodiment, the setting is LCD
Although the touch keys of the unit 72 are used, other methods can also be used for setting using a combination of operation unit keys called SP mode.

Next, the storage of image data will be described. The scanner unit 1 is activated to read the document information at the same size, and the read data is subjected to a predetermined process in the IPU 5 to output only the black data BLKDT0 to 7. The black data passes through the I / F 12 and the image memory 9, 1
It is input to 0 and stored. The image memory (1) 9 is B
It is a memory of 8 bits per pixel, which is a size capable of storing LDDT 0 to 7 as it is.

Next, editing on the memory will be described. FIG. 9 is a flowchart showing another example of the processing contents in the blank page deletion mode. In this flowchart, the same parts as those in FIG. 8 are designated by the same step numbers. In the present embodiment, when the blank sheet shift mode is set, the shift direction of the blank sheet image portion, whether to shift across pages, and the like are confirmed. In addition, the same processing is performed in the same steps as the steps described above.

FIG. 10 is a flow chart showing a subroutine for editing on the memory. First, the contour tracking in S71 will be described. The input image is raster-scanned on the image memories 9 and 10 to find a pixel to start tracking. Next, in the case of the outer contour line, the tracking pixel is traced counterclockwise from the tracking start pixel, and in the case of the inner contour line, the contour pixel is traced clockwise. Then, the tracking of the contour line of one pixel set is completed by returning to the tracking start pixel again. The above operation is repeatedly executed until there are no untracked contour pixels.

FIG. 11 shows an example in which the contour line of one pixel set is traced, and the direction of the contour line is 0 to 7 as shown in FIG. First, as in the case of the stippling in FIG. 11, the tracking start pixel is searched by raster scanning. For example, if the tracking start pixel is found at the position (i1, j1), the pixel immediately before the raster scan is a white pixel. Yes It is judged to be the outer contour line, and tracking is started counterclockwise from this position.

Next, tracking is started counterclockwise from the direction "4" in FIG. The neighboring pixels are checked counterclockwise from the direction of “4”, and the direction of the pixel found first is set as the direction of the contour line. Next, the tracking center pixel is moved to that pixel, the neighboring pixels are checked counterclockwise from the previous contour line direction (direction of "2"), and this is repeated until the tracking start pixel is reached. By performing such processing, a contour line as shown by the arrow group in FIG. 11 is obtained.

Of the tracing results, only the contour tracing on the outer side is stored in the memory as contour line data. As shown in FIG. 13, the contour line data is formed of a start position (minimum value) and a length (maximum value-minimum value) by taking the minimum value and the maximum value of the contour coordinates. The first line in FIG. 13 shows the contour tracking result in FIG.

In S72 of FIG. 10, image determination is performed based on the contour data. Of the contour data obtained as a result of the contour tracing, depending on the sizes in the X direction and the Y direction (see FIG. 13), whether the inside of the contour is image noise or a character is determined by a predetermined threshold L1. , L2. If the contour data is larger than L2,
The form of the pixel set is determined based on the number of appearances of the data representing the direction of the contour line. This is because a contour line having a large area such as an area varies in the direction of the contour line in FIG. 12, but the contour line like a line shows a strong bias in two specific directions. Therefore, by determining the probability of the contour data in each direction of 0 to 7 and calculating the difference between the maximum value and the minimum value, it is possible to determine whether it is a line figure or an area figure. In the present embodiment, the determination is made by comparing the magnitude of the constant K and Pmax-Pmin (S76). This image determination data is coded as shown in FIG. 14 and registered in the order shown in FIG.

No special processing is performed thereafter on the pixel set recognized as noise. The pixel set recognized as a character is cut out as a character portion in S75 and subjected to pattern matching to be recognized as a character stored in advance. In addition, the pixel group recognized as a line figure is subjected to the belting process (S77).

In the present embodiment, the journal of the Institute of Electronics and Communication Engineers,
April 1985, Vol. J68-D, NO. 4,845
As described in pages 852 to 852, or in Japanese Patent Laid-Open No. 62-286177, a method is used in which contour lines on both sides of a line graphic image are traced to find the center line and approximated as a polygonal line vector. . Perform pattern matching in the vectorized state, detect the direction of the tip of the arrow,
Determines the direction of the vector. Arrows are vectorized from the start and end points of the polygonal line vector.

Next, an area where no image data exists is searched (S79). A portion having no image information is found from the contour line search result of FIG. 13 and is stored in the memory as blank space area data. The blank space area data is composed of the start position and length of the area.

The first line in FIG. 15 shows the area information result of the blank space in FIG. Here, instead of digitizing all areas in which image data does not exist, a certain threshold value is set in advance, and only areas having a size equal to or larger than the numerical value are digitized. The threshold can be set either by its area or the dimension of the axis. The length digitized in FIG. 15 serves as a criterion for determining whether to delete or reduce the area when blank space is deleted or reduced.

After that, the CPU 13 edits the original image on the image memories 9 and 10 in accordance with the editing contents preset by the operation unit 3. Editing related to the present invention
If the blank image portion is found when the mode to erase the blank image portion is set, the size of the area of the portion without the image information is calculated, and the calculation result is based on the preset reference value. If it is large, the area is erased or reduced, and the image data is shifted by the reduced or erased size.

In the present embodiment, all image editing is done by CP.
Although it is performed by software processing by U13, the processing may be performed by dedicated hardware for image editing. The contents of the image memories 9 and 10 after processing and editing are
Via I / F 12, GAVD 6, LED control board 8,
The data is written on the photosensitive drum 35 by the LED and output on the transfer paper (S10 in FIG. 8). Then, in the flowchart, the state after initialization is returned to a state in which it is determined whether or not there is an operation instruction from the operation unit 3.

FIG. 17 is an explanatory diagram showing the contents of the first process in the blank page deletion mode. In the figure, (a) shows an original document, and (b) shows an image-edited and copied document (transfer sheet). The shift direction is the Y axis (this depends on the direction in which the original is placed, the Y axis in this embodiment), and the target blank sheet size is 30 m.
When the copying operation is performed with the transfer paper size being equal to or larger than the original and the space after cutting being 10 mm, the copy original shown in FIG. 17A can be obtained from the original shown in FIG. 17A. That is, as shown in FIG. 9B, the image areas 91, 92, and 93 of the original document shown in FIG. A blank area (area without image information) 94 between areas 92 and 93 is collected at the bottom of the copy document. By doing so, the blank area 94 of the copy original can be effectively used for writing a memo.

FIG. 18 is an explanatory view showing the contents of the second processing in the blank page deletion mode. When the ecology mode is set in the transfer paper size setting, the blank area 94
If it is possible to reduce the size of the transfer paper after cutting, the transfer paper is automatically changed to an appropriate size. That is, when the blank area 94 is removed from the A3 original document shown in FIG.
If the papers 92 and 92 fit on the A4 transfer paper, an A4 copy original is obtained as shown in FIG. In the above embodiment, only the X-axis was processed, but at the same time, the X-axis,
It is also possible to set the Y axis independently. At the same time, since the present copying machine is capable of recognizing characters, it is also possible to automatically determine the shift direction (X axis or Y axis) from the direction of the character after the character string is recognized, and perform the copying operation.

FIG. 19 is an explanatory view showing the third processing contents in the blank sheet portion deletion mode. In this embodiment, there is page-to-page shift, the number of pages is displayed, the shift prohibited area is set, and the Y axis is set to 20 mm. When this setting is performed and a copy operation is performed, FIG.
19B is obtained from the original document of FIG. That is, as shown in FIG.
3 and a blank area 94, a first original document having image areas 92 and 95 and a blank area 94, and a third original document having image area 96 and a blank area 94. If you cut the blank area 94,
The image area portion fits on two sheets of transfer paper, as shown in FIG. However, the image area 95 is divided into a lower portion 95a of the first transfer sheet and an upper portion 95b of the second transfer sheet, and is copied. In addition, as shown in FIG.
The page number "1" is attached to the second transfer sheet, and the page numbers "2" and "3" are attached to the second transfer sheet. Further, a shift inhibition area 97 is provided above and below the transfer sheet.
