The interface section 2 receives the image reading signal from the central control section 1 and inputs it to the scanner 14 connected to the interface section 2. The scanner 14 receives the image reading signal from the interface unit 2 and reads the image. The scanner 14 is realized by, for example, a contact image sensor, irradiates a document placed at a predetermined position with light, detects light reflected from the document surface, and reads the image by converting it into an electric signal.

The image editing section 5 comprises an editing control section 3 and an editing storage section 4, and electric signals of an image read by the scanner 14 are stored in the editing storage section 4 as image data. The edit control unit 3 receives a command from the central control unit 1 and performs reference point setting, image rotation processing, and enlargement / reduction processing.

In the first embodiment, the case where the original 17 is divided into four and read will be described, but the original 17 is not necessarily divided into four.
It is not necessary to divide it, and the number of divisions may be arbitrarily determined depending on the maximum reading range of the scanner 14 and the size of the document 17.

FIG. 2 is a diagram showing the setting state of the original reading range of the original 17 in the first embodiment of the present invention, and FIG.
FIG. 6 is a diagram showing areas 1 to 4 set on a document. Manuscript 1
7 is, for example, a virtual dividing line 18 connecting the midpoint portion e of the corner portions a and b and the midpoint portion f of the corner portions c and d, and the midpoint portion g of the corner portions a and c.
And an imaginary dividing line 19 that connects the midpoints h of the corners b and d are equally divided into four areas, that is, area 1, area 2, area 3 and area 4, and read.

The original 17 does not necessarily have to be equally divided, and thus the virtual dividing line 18 does not necessarily have to be a line connecting the midpoint portion e and the midpoint portion f. That is,
A line connecting an arbitrary point between the corners a and b and an arbitrary point between the corners c and d may be the virtual dividing line 18. Similarly, for the virtual dividing line 19, a line connecting an arbitrary point between the corners a and c and an arbitrary point between the corners b and d may be used as the virtual dividing line 19. Further, in the present embodiment, an example in which the document 17 is divided into four is described, so that
Although the virtual dividing lines 18 and 19 of the book are set, the number of virtual dividing lines is not limited to this, and an arbitrary number of virtual dividing numbers is set depending on the dividing number of the document 17.

When the enlargement reading mode is set in the central control unit 1 by the key operation of the keyboard 10 and an instruction to read an image is issued from the central control unit 1 via the interface unit 2, the scanner 14 causes the scanner 14 to display the image in the area 1. Start reading.
The read image data is stored in the edit storage unit 4 of the image editing unit 5.
Memorized in.

The image of the area 1 read by the scanner 14 is displayed on the display unit 15, and first, the editing control unit 3 of the image editing unit 5 sets a reference point for combining the images later. Two reference points are set on a virtual dividing line where the divided areas of the original 17 are in contact with each other. That is, the reference point setting position 20 is located on the midpoint portion e of the corners a and b of the document 17, and the reference point setting position 2 is located on the midpoint portion g of the corners a and c.
1 is the reference point setting position 23 on the midpoint h of the corners b and d.
However, the reference point setting position 24 is on the midpoint f of the corners c and d,
A reference point setting position 22 is provided on an intersection point w of a virtual dividing line 18 connecting the middle points e and f and a virtual dividing line 19 connecting the middle points g and h. The reference point is set, for example, by moving the cursor to the reference point setting position on the image displayed on the display unit 15 by operating the keyboard 10, and is set every time the image in the areas 1 to 4 is read. On the image of the area 1, a reference point 25 is set at the reference point setting position 20, a reference point 26 is set at the reference point setting position 21, and a reference point 27 is set at the reference point setting position 22.

In the vicinity of the edge of the read document, the read image is distorted due to, for example, a document placement error or a variation in the read signal. Therefore, the scanner 14 reads a range exceeding the size of the read document. Therefore, for region 1,
Range set as area 1, that is, corners a, e, w, g
The range beyond the range surrounded by, that is, corners a, k,
The range surrounded by v and q is read. This is region 2
Since the same applies to No. 4, the areas in which the respective areas overlap each other are read. Reference points are areas 1 to 4
Since it is provided at a position serving as a reference for synthesizing the images up to, it is sufficient that the areas are in contact with each other or overlap each other. Therefore, the reference point may be set at any position within a range where the regions 1 to 4 overlap each other, that is, as long as it is a portion shown by a diagonal line in FIG.

When the setting of the reference points 25 to 27 is completed, the central control section 1 reads the coordinates of the set reference points 25 to 27, and the edit storage section of the line segment 37 connecting the reference points 25 and 27. 4, the inclination α1 with respect to the x-axis and the length L1 are calculated, and the inclination α2 with respect to the x-axis and the length L2 of the line segment 38 connecting the reference point 26 and the reference point 27 with respect to the x-axis are calculated. After being stored in the image editing unit 5, the image in the area 1 is stored in the intermediate storage unit 7. At this time, the inclinations α1 and α2 are
The tilt formed with the y-axis of the edit storage unit 4 may be obtained. The calculated inclinations α1 and α2 and the lengths L1 and L2 are used for a correction to be described later in order to eliminate the image shift when the images of the region 1 and the region 2 or the region 3 are combined.

Subsequently, the central control unit 1 commands the reading of an image via the interface unit 2, and the scanner 14 starts reading the image of the area 2. The read image data is stored in the edit storage unit 4 of the image editing unit 5.

The image of the area 2 read by the scanner 14 is displayed on the display unit 15 as in the case of the area 1, and the editing control unit 3 of the image editing unit 5 first sets a reference point for combining the images. It On the image of area 2, area 1
In the same manner as in the case of
However, the reference point 29 is set at the reference point setting position 22, and the reference point 30 is set at the reference point setting position 23.

Next, the reference point 2 set by the central controller 1
The coordinates 8 to 30 are read, the inclination α3 and the length L3 of the line segment 39 connecting the reference point 28 and the reference point 29 with the x axis of the edit storage unit 4 are calculated, and the reference point 29 and the reference point are calculated. The inclination α4 of the line segment 40 connecting the lines 30 and the x axis of the edit storage unit 4 and the length L4 are calculated. Subsequently, the slope α1 and the length L1 of the line segment 37 of the region 1 calculated previously and the line segment 3 of the region 2 are calculated.
Both images are corrected based on the inclination α3 of 9 and the length L3. This correction eliminates a parallel shift and a magnification error that occur when the originals are not aligned when the image is read, and prevents a shift in the combined image. , The slope α of the line segment 39 of the region 2
1, α3 and the lengths L1, L3 are processed so as to match. The central control unit 1 calculates the rotation angle θ1 from the inclinations α1 and α3, that is, the angle formed by the line segment 37 and the line segment 39, and inputs it to the edit control unit 3. The edit control unit 3 rotates the image of the region 2 by the input rotation angle θ1 and corrects the parallel displacement with the region 1. Further, in the central control unit 1, the length L1
Then, a magnification A1 = L1 / L3 of the length L3 with reference to the length L1 is calculated from the length L3 and input to the edit control unit 3.
The edit control unit 3 enlarges or reduces the image of the area 2 by the input magnification A1 and corrects the deviation of the magnification from the area 1.

The image of the area 2 for which the correction has been completed is combined with the image of the area 1 and stored in the intermediate storage section 7. That is, in the central control unit 1, the coordinates of the reference point 25 of the area 1 and the area 2
The coordinates of the area 2 are translated so that the coordinates of the reference point 28 of the area 1 match and the coordinates of the reference point 27 of the area 1 and the coordinates of the reference point 29 of the area 2 match.
Memorized in.

Similarly to the area 2, the images of the areas 3 and 4 are read, the reference points are set, the image is edited, and the images of the areas 1 to 4 are combined and stored in the intermediate storage section 7. It The image data stored in the intermediate storage unit 7 is compressed by the data compression / decompression unit 8 and registered in the magneto-optical disk 16 via the interface unit 9.

FIG. 4 is a flow chart showing the operation of the first embodiment. In step a1, the enlarged read mode is set in the central control unit 1 by operating the keys of the keyboard 10, and the central control unit 1 commands the scanner 14 via the interface unit 2 to read an image. Next, in step a2, the image of the area i is read by the scanner 14,
It is input to the edit storage unit 4 of the image editing unit 5. The input image is displayed on the display unit 15, the cursor key 11 of the keyboard 10 is operated in step a3, and the reference point is set in step a4.

In step a5, it is judged whether or not the setting of the reference point is completed. If it is completed, the process proceeds to step a6, and if it is not completed, the process returns to step a3 to continue the setting of the reference point. In step a6, the image editing processing of the read image is performed by the editing control section 3 based on the calculation of the central control section 1. When this process ends, the image is stored in the intermediate storage unit 7 in step a7.

At step a8, it is judged whether or not the reading of the entire area is completed, and if so, step a9.
Go to step a12 if not completed,
The reading of the next area is instructed, and the process returns to step a2 to start reading. In step a9, the registration mode is set in the central control unit 1 by operating the keys of the keyboard 10,
The central control unit 1 instructs the interface unit 9 to register an image. In step a10, identification data is added to the image to be registered, and in step a11, the image data is data-compressed and the magneto-optical disk 16 is added together with the identification data.
And the series of operations is completed.

FIG. 5 shows the area 1 stored in the intermediate storage unit 7.
It is a figure which shows ~ 4. FIG. 5A shows the area 1 and FIG.
(2) shows areas 1 and 2, and FIG.
3 and FIG. 5 (4) are diagrams showing regions 1 to 4. Area 1
In order to synthesize the images of
5 and the reference point 28 of the area 2 are moved in parallel so that the reference point 27 of the area 1 and the reference point 29 of the area 2 coincide with each other. Similarly, for the regions 3 and 4, the coordinates of the newly stored regions are translated in parallel so that the overlapping reference points coincide with each other to synthesize an image, and the images are stored in the intermediate storage unit 7.

As described above, the standard for dividing the original 17 larger than the maximum reading range of the scanner into a size that can be read by the scanner, and combining the read and divided images in the image editing unit 5 with the image. Since the points 25 to 36 are set, and the images read by dividing based on the set reference points 25 to 36 are combined and stored, there is no need to reduce the original, and an image when obtaining a full-scale image The need for pasting is eliminated. Therefore, the time for reducing the size of the original or for adhering the images becomes unnecessary, and the working time efficiency is improved. Further, the image quality is not deteriorated due to the reduction, and the image can be read faithfully.
In addition, paper for reduction is not required, which can reduce costs and make effective use of resources.

The second embodiment will be described below.

This embodiment is similar to the first embodiment and is shown in FIG.
Commonly referred to. The feature of the present embodiment is that the reference points for synthesizing the images after the split input are directly written on the original to read the image, the split input images are synthesized based on the written reference points, and the images are stored. That is what I did.

In this embodiment as well, an example in which the original 45 is divided into four and read in the same manner as in the first embodiment will be described. However, depending on the maximum reading range of the scanner 14 and the size of the original 45, the number of divisions can be arbitrarily set. May be determined.

FIG. 6 is a diagram showing the setting state of the original reading range of the original 45 in the second embodiment of the present invention, and FIG. 7 is a diagram showing areas 1 to 4 set in the original. On the original 45, a reference point such as a “+” sign is set on a straight line parallel to each divided area along the arrangement direction of the areas as an example for synthesizing the divided and read images later. To be done. For example, the reference point setting position 4 is set on the corner a of the document 45.
6, reference point setting position 47 on corner b, reference point setting position 48 on corner c, and reference point setting position 49 on corner d.
However, the reference point setting position 50 is on the midpoint e of the corners a and b,
The reference point setting position 51 is on the midpoint f of the corners c and d, the reference point setting position 52 is on the midpoint g of the corners a and c, the corner b,
The reference point setting position 53 is set on the midpoint h of d.

Since the original 45 is not necessarily divided into equal parts, if the original 45 is not equally divided, the reference point setting position 50 is set to an arbitrary point between the corners a and b. It Similarly, the reference point setting position 51 is an arbitrary point between the corners c and d, the reference point setting position 52 is an arbitrary point between the corners a and c, and further, the reference point setting position 53. Is set at an arbitrary point between the corners b and d. In addition, in the present embodiment, since an example in which the original 45 is divided into four is described,
Although one reference point setting position 50, 51, 52, 53 is set, the number of reference point setting positions is not limited to this, and the original 45
An arbitrary reference point setting position is set according to the number of divisions.

The reference point setting positions 46 to 53 are set in the scanner 1
4 is set in a marginal area that does not hinder the image to be read within the range that can be read by 4, for example, the shaded area shown in FIG. The reference points 54 to 65 are set for each of the divided areas by directly writing on a document with a writing instrument, for example, a pencil, which can be read by the scanner 14 at each reference point setting position.

When the setting of the reference points 54 to 65 is completed, the image is read. When the enlargement reading mode is set in the central control unit 1 by the key operation of the keyboard 10 and the image reading is instructed from the central control unit 1 through the interface unit 2, the scanner 14 starts reading the image in the area 1. . The read image data is stored in the edit storage unit 4 of the image editing unit 5. The read image of the area 1 is displayed on the display unit 15, and the central control unit 1 controls the reference points 54 to 56.
The coordinates of are read. The coordinates are read from the reference points 54 to 5
Is it performed by moving the cursor of the display unit 15 to the position marked with 6 and operating the keyboard 10?
Alternatively, the recognition is performed by automatically obtaining the coordinate position of the reference point such as the "+" symbol.

Next, when the image is read, the rotation angle and the magnification for correcting the parallel deviation and the magnification error caused by the deviation of the alignment of the document are calculated, and the rotation processing and the image of the image based on the calculated values are calculated. Enlargement / reduction processing is performed. Editing is performed so that two predetermined reference points are horizontal or vertical from the read coordinates of the reference points 54 to 56. First, in the central control unit 1, a line segment 68 connecting the reference points 54 and 55 of the area 1 is made parallel to the x axis of the edit storage unit 4, or a line segment 67 connecting the reference points 54 and 56. From the coordinate read so as to be parallel to the y-axis of the edit storage unit 4, that is, the angle formed by the rotation angle θ5, that is, the line segment 68 connecting the x-axis with the reference point 54 as a reference and the reference points 54 and 55, or Y-axis based on reference point 54 and reference point 5
The angle formed by the line segment 67 connecting the lines 4 and 56 is calculated, and the edit control unit 3
To enter. The edit control unit 3 rotates the image about the reference point 54 by the input rotation angle θ5 and corrects the horizontal or vertical shift of the image. Next, the image is cut out so that the reference points 54 to 56 are the three corners in the range of the area 1. Subsequently, the reference points 54 to
From the coordinates of 56, the length L9 of the virtual line 66 connecting the reference points 55 and 56 is calculated and stored in the image editing unit 5.

The image of the cut out area 1 is stored in the intermediate storage unit 7.
Memorized in. At this time, the central control unit 1 stores the reference point 55 of the area 1 so that the reference point 55 coincides with the center of the area of the intermediate storage unit 7 in the x-axis direction and the reference point 56 coincides with the center of the y-axis direction. It

Subsequently, the central control unit 1 commands the reading of an image through the interface unit 2, and the scanner 14 starts reading the image of the area 2. The read image data is stored in the edit storage unit 4 of the image editing unit 5. The read image of the area 2 is displayed on the display unit 15 similarly to the area 1, the coordinates of the reference points 57 to 59 are read by the central control unit 1, and the image rotation processing is performed. Regarding the rotation processing, as in the case of the region 1, the central control unit 1 controls the reference points 57 and 5
A line segment 71 connecting 8 is parallel to the x-axis of the edit storage unit 4, or a line segment 70 connecting the reference points 58 and 59.
The rotation angle θ6 is calculated from the read coordinates of the reference points 57 to 59 so that is parallel to the y-axis of the edit storage unit 4, and is input to the edit control unit 3. The edit control unit 3 rotates the image around the reference point 58 by the input rotation angle θ6 and corrects the horizontal or vertical shift of the image.

Next, the central control unit 1 obtains the length L12 of the virtual line 69 connecting the reference points 57 and 59, and the magnification A5 of the length L12 based on the length L9 obtained in the area 1.
= L9 / L12 is calculated and input to the edit control unit 3. The edit control unit 3 enlarges or reduces the image of the area 2 based on the magnification A5, and corrects the deviation of the magnification from the area 1. The processed image is cut out so that the reference points 57 to 59 are the three corners of the range of the area 2, and is stored in the intermediate storage unit 7. At this time, the central control unit 1 causes the reference point 57 of the area 2 to coincide with the reference point 55 of the area 1, and the reference points 54, 5
5, 57 and 58 are stored so as to be arranged in a straight line.

Similar to the area 2, the images in the areas 3 and 4 are read, rotated, enlarged / reduced and cut out, and stored in the intermediate storage section 7. Area 3 has reference points 56, 6
0 is coincident, and the reference points 54, 56, 60 and 61 are stored so as to be arranged on a straight line, and the area 4 is stored in the reference points 59 and 63.
Alternatively, the reference points 62 and 64 coincide with each other, and the reference points 58 and 5
9, 63, 65 or reference points 61, 62, 64,
65 are stored so as to be arranged in a straight line. Therefore, the images of the areas 1 to 4 stored in the intermediate storage unit 7 are combined and stored. The data stored in the intermediate storage unit 7 is compressed by the data compression / decompression unit 8 and registered in the magneto-optical disk 16 via the interface unit 9.
