DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing device associated with an input / output device of a facsimile machine, for example.

[0002]

2. Description of the Related Art Conventionally, in an electronic apparatus including a personal computer and a word processor, for example, an image printed on a document is read by using a reading device such as a scanner, and an original image signal is generated and stored. I do.
In this electronic device, an image processing operation is performed in which a part or the whole of an original image represented by a stored original image signal is enlarged or reduced to deform or move.

In this case, when an operator of an electronic device specifies a target area including an image to be transformed and moved in the original image, a coordinate system set on the original image is used to express coordinates by numerical values. Need to represent the target area. This coordinate system is automatically set with respect to the original image represented by the original image signal when the original image signal is generated by, for example, the reading device, so that it is difficult to obtain the position coordinates of the target area from the image of the original. It is.

The above-mentioned electronic apparatus uses a display device having a two-dimensional plane visual display area for designating coordinates representing a target area, and displaying an original image signal in a so-called bitmap display. Display the original image inside.
Further, a so-called cursor that moves in the visual display area in conjunction with an operation device such as a keyboard and a mouse is displayed in the visual display area so as to overlap the original image.
The operator operates the operating device to move the cursor, for example, to overlap and display a point on the boundary of the target area. The electronic device automatically obtains the coordinates of the position where the cursor is displayed, thereby obtaining the coordinates representing the target area.

At present, there is a demand for realizing the same image processing operation as that of the above-mentioned electronic equipment also in a copying machine and a facsimile machine. Copiers and facsimile machines
Since the display device and the operation device described above are not included in many cases, it is difficult to specify the target region using the cursor described above.

As a conventional technique for performing an image processing operation in a copying machine, there is an image processing apparatus disclosed in Japanese Patent Application Laid-Open No. Sho 62-101174. In this image processing apparatus, an image obtained by superimposing a grid-like ruled line on an image to be processed is printed on recording paper in order to specify a target area to be cut out from the image to be processed. The operator grasps the coordinate system set on the image from the ruled line printed on the recording paper, and inputs coordinates representing both ends of the diagonal line of the target area using the numeric keypad. In the image processing apparatus, the operator recognizes the target area based on the coordinates input from the numeric keypad, and prints the image on which the image outside the target area has been deleted on the recording paper again. In this image processing apparatus, since only the target area to be extracted is specified, it is difficult to deform or move the target area.

[0007]

SUMMARY OF THE INVENTION An object of the present invention is to provide an image processing apparatus having no display device for performing bitmap display, and to perform image processing operations including image deformation or movement by designating a target area. It is an object of the present invention to provide an image processing apparatus that can perform the processing.

[0008]

According to the present invention, there is provided an original image signal input means for inputting an original image signal representing an original image, and a coordinate system image in which a coordinate system for determining coordinates in the original image is visually displayed. And a superimposed image signal generating unit that generates a superimposed image signal representing the superimposed image by superimposing the coordinate system image signal representing the superimposed image signal on the original image signal input from the original image signal input unit. In response to the superimposed image signal, a superimposed image printing means for printing the superimposed image on a predetermined recording paper, coordinate input means for inputting a pair of coordinates obtained from the superimposed image printed on the recording paper, and coordinate input An image of the original image included in the target area determined based on one of the pair of coordinates input from the means is moved in a moving area determined based on the other of the pair of coordinates. As an image processing apparatus which comprises a processing means for processing an original image signal inputted from the original image signal input means is moved to. According to the present invention, in the image processing apparatus, when the original image signal is input from the original image signal input means, the superimposed image generating means generates the above-described superimposed image signal and causes the superimposed image to be printed on recording paper. In the superimposed image, since the coordinate system image in which the coordinate system is visually displayed is superimposed on the original image, it is possible to know the coordinates of any coordinate point in the original image simply by looking at the superimposed image. Therefore, when the operator determines the target area and the moving area with reference to the superimposed image printed on the recording paper, the operator can easily know the pair of coordinates for indicating the target and the moving area. . The processing unit moves the image included in the target region in the original image to the moving region by processing the original image signal based on the pair of coordinates input from the coordinate input unit as described above. Accordingly, an image processing operation of moving an image in an original image by designating a target area and a moving area can be performed by an image processing apparatus including only a coordinate input unit having a configuration for inputting a numerical value representing a coordinate. It can be carried out. Therefore, since the coordinate input means can be realized by, for example, a keyboard including only a numeric keypad, for example, coordinate input means combining a display device and a mouse, or coordinate input means combining the display device and a tablet device is used. No need to prepare. Therefore, the structure of the image processing apparatus can be simplified as compared with a conventional image processing apparatus that performs the above-described image processing operation.

The present invention also provides an original image signal input means for inputting an original image signal representing an original image, and an original image on a predetermined recording sheet in response to the original image signal input from the original image signal input means. An original image printing means for printing, and a transparent sheet on which a coordinate system image in which a coordinate system for defining coordinates in the original image is visually displayed are printed, are superimposed on the recording paper on which the original image is printed. The coordinate input means for inputting a pair of coordinates obtained by the above, and the image of the original image included in the target area determined based on any one of the coordinates of the pair of coordinates input from the coordinate input means, Processing means for processing the original image signal input from the original image signal input means so as to be moved to a movement area determined based on the other one of the coordinates. It is a processing apparatus. According to the present invention,
In the image processing apparatus, when an original image signal is input from the original image signal input unit, the original image printing unit prints the original image on a recording sheet. The image processing apparatus is provided with a transparent sheet on which the above-described coordinate system image is printed, and the operator superimposes the transparent sheet on the original image. Thus, the operator can know the coordinates of any coordinate point in the original image. Therefore, when the operator determines the target area and the moving area with reference to the original image printed on the recording paper on which the transparent sheet is superimposed, a pair of coordinates for indicating the target and the moving area are set. Can be easily known.
The processing means processes the original image signal as described above based on the pair of coordinates input from the coordinate input means,
The image included in the target area in the original image is moved to the moving area. Accordingly, an image processing operation of moving an image in an original image by designating a target area and a moving area can be performed by an image processing apparatus including only a coordinate input unit having a configuration for inputting a numerical value representing a coordinate. It can be carried out. therefore,
Since the coordinate input means can be realized by a keyboard including only numeric keys, for example, coordinate input means combining a display device and a mouse, or coordinate input means combining the display device and a tablet device are prepared. No need. Therefore, the structure of the image processing apparatus can be simplified as compared with a conventional image processing apparatus that performs the above-described image processing operation. Further, in the image processing apparatus of the present invention, there is no need to generate a superimposed image as compared with the image processing apparatus of the first aspect. Further, the transparent sheet need not be generated each time a certain original image signal is input, but may be attached to the image processing apparatus in advance. Accordingly, the image processing apparatus of the present invention simplifies the structure by eliminating the superimposed image signal generating means as compared with the image processing apparatus of claim 1, and further performs processing performed inside the image processing apparatus. The operation can be simplified.

[0010] In the present invention, the original image printing means may further print a symbol representing a predetermined reference coordinate point on the recording paper on which the original image is printed, and may print the transparent image on which the coordinate system image is printed. On the sheet, a symbol representing the reference coordinate point is further printed, and the recording sheet on which the original image is printed and the transparent sheet on which the coordinate system image is printed have the same reference coordinate point. It is characterized by being superimposed on. According to the present invention, reference coordinate points are clearly indicated by symbols on the recording paper on which the original image is printed and on the transparent sheet on which the coordinate system image is printed. By superimposing the recording paper and the transparent sheet so that the reference coordinate points match, a coordinate system set in advance on the original image and a coordinate system represented by a coordinate system image printed on the transparent sheet, They can be easily matched without deviation. Therefore, when the operator obtains the above-mentioned pair of coordinates, it is possible to prevent errors in the coordinates.

In the present invention, the shape of the recording paper is selected to be jointly with the shape of the transparent sheet on which the coordinate system image is printed, and the recording paper on which the original image is printed, and the coordinate system image Is superimposed on the transparent sheet on which is printed so that the outer periphery of the transparent sheet coincides with the transparent sheet. According to the invention, the recording paper and the transparent sheet have the same shape. Thereby, by superimposing the recording paper and the transparent sheet so that the outer periphery coincides, a coordinate system set in advance on the original image and a coordinate system represented by a coordinate system image printed on the transparent sheet are represented by: They can be easily matched without deviation. Therefore, when the operator obtains the above-mentioned pair of coordinates, it is possible to prevent errors in the coordinates.
Further, in the image processing apparatus of the present invention, an image other than the original image is not printed on the recording paper as compared with the image processing apparatuses of the first and third aspects. Therefore, the recording paper can be easily diverted to another use using the original image.

Further, according to the present invention, when the target area and the moving area are congruent, the processing means keeps the image included in the target area as it is, and when the target area and the moving area are congruent, When there is no image, the image is deformed at a magnification based on the size of the target area and the moving area. According to the present invention, the processing means of the image processing apparatus described above can move the image included in the target area to the moving area and simultaneously deform the image. At this time, whether or not to deform the image is determined by whether or not the target area and the moving area are congruent, and the magnification when deforming the image depends on the size of the target area and the moving area. It is determined based on. Therefore, the operator can input the presence / absence of movement and deformation of the image included in the target area and the magnification at the time of deformation only by inputting the pair of coordinates. Therefore, the movement and deformation of the image can be easily instructed in the same procedure as when the image is moved.

In the present invention, the magnification based on the size of the target area and the moving area is along each coordinate axis of the target area and the moving area for each direction along each coordinate axis of the coordinate system. It is characterized by being individually determined based on the ratio of the width in the direction. According to the present invention, when the image included in the target area is deformed by the above-described processing means, the magnification is individually determined for each direction along each coordinate axis of the coordinate system. Therefore, it is also possible to perform irregular image deformation such that the magnification in each direction along each coordinate axis is different. Further, since the magnification is determined as described above, the magnification desired by the operator can be easily and reliably determined.

The operation of transmitting an audio signal is similar to the operation of transmitting an image signal. Instead of an original image signal, an audio signal obtained by converting an audio input by a microphone of the handset 3 into an electric signal is used. The difference is that the other actions are equal. The operation of receiving an audio signal is similar to the operation of receiving an image signal, and an audio signal reproduced from a transmission signal by the modem 9 is output as audio from a speaker of the handset 3 or an external speaker provided inside the housing 2. But the other operations are equal.

The numerical value of “9” is drawn such that the value increases in a direction away from the origin. In the following description, the intersection of the line segments 65 and 66 is represented by a numerical value "m" drawn on the left side of one end of the line segment 66.
And a numerical value “n” drawn below one end of the line segment 65, and is expressed as an intersection (m, n).

When the interval between the line segments 66 is larger than the width of a single pixel constituting the original image in the X direction, the numerical value assigned to the line segment 66 and the X coordinate of an arbitrary point on the line segment 66 Does not match. When the interval between the line segments 65 is larger than the width of a single pixel constituting the original image in the Y direction, the line segment 65
Does not match the Y coordinate of an arbitrary point on the line segment 65. A single image is formed from a very large number of pixels, and the interval between graduations on the coordinate axis is often equal to the width of the single pixel in the X and Y directions. In order to make the coordinate system image 61 easy to see, the interval between these line segments 65 and 66 is
It is preferable that the width is larger than the width in the Y and X directions.

FIG. 5 shows a case where only the original image signal to be processed in the image processing operation is given to the printing device 14 and the recording paper 6
FIG. 4 is a schematic diagram illustrating an original image 71 printed on the image No. 2. The original image 71 includes an elliptical image 72. The XY orthogonal coordinate system set for the original image 71 is set such that the vertex 67 of the recording paper 62 is set as the origin, and the X and Y coordinate axes 63 and 64 are parallel to the outer sides 68 and 69 of the recording paper 62. You. Since the original image 71 does not include an image for visually displaying the X and Y coordinate axes 63 and 64, the X and Y coordinate axes 63 and 64 are not printed on the recording paper 62 on which the original image 71 is printed. Therefore, it is difficult for the operator to know the coordinates of any point in the original image 71 only by looking at the original image 71 printed on the recording paper 62.

FIG. 6 is a flowchart for explaining an image processing operation using the facsimile machine 1 described above.
The detailed procedure of the image processing operation will be described with reference to this flowchart.

When starting the image processing operation, the operator first operates the operation mode key 41 and the function key 42 of the operation panel 5 to select the image processing operation. At the same time, a document to be processed is placed on the document table 20 of the automatic document feeder. When the original is placed, step a
The process proceeds from step 1 to step a2.

In step a2, the central processing circuit 7 waits for an instruction to start an image processing operation from the operating device 4, and when instructed, proceeds from step a2 to step a3. The image processing operation is started, for example, by using the operation panel 5
Is designated by an instruction signal generated by the facsimile control circuit 6 when the enlargement / reduction key 37 and the copy key 32 are continuously pressed.

In step a3, the central processing circuit 7 first causes the image input device 11 to sequentially read the originals placed on the original placing table 20, and generates an original image signal for each original. . Next, the central processing circuit 7 causes the output image processing circuit 12 to start an image processing operation. In the output image processing circuit 12, first, the original image signal and the coordinate system image signal are synthesized by the superimposed image signal generation unit 12a so that the coordinate systems match, and a superimposed image signal representing a superimposed image is generated. Next, a superimposed image signal is supplied to the printing device 14 to print the superimposed image on a recording sheet. The recording paper on which the superimposed image is printed
When discharged from the printing device 14, the process proceeds to step a4.

FIG. 7 is a schematic diagram showing a superimposed image 75 printed on the recording paper 62. The superimposed image is an image in which the coordinate system image 61 is superimposed on the original image 71, and includes the line segments 65 and 6.
6 and the elliptical image 72 are both drawn. This superimposed image 75
Is the same as the original image 71. Further, the arrangement of the coordinate system with respect to the recording paper 62 on which the superimposed image 75 is printed is the same as that of the recording paper 62 on which the original image 71 is printed.

Referring back to FIG. In step a4,
The output image processing circuit 12 waits for input of coordinates for determining a target area in the original image including the image to be moved. The operator selects the superimposed image 7 printed on the recording paper 62.
5, a target area including an image to be moved in the original image 71 is determined, and coordinates representing the target area are input. When the coordinates are input, the output image processing circuit 12
The processing unit 12b determines a target area based on the input coordinates. When the target area is determined, the process proceeds to step a5.

In the operation of inputting the coordinates representing the target area by the operator, first, the enlargement / reduction key 37 and the area designation key 34 of the operation panel 5 are continuously pressed. Then
The coordinates are input using the numerical key group 31 of the operation panel 5. For example, when inputting the intersections (1, 3) and (4, 6) successively, each key of the numerical key group 31 is pressed,
"1", "#", "3", "*", "4", "#",
"6" is sequentially input. “#” Is used as a symbol for separating numerical values representing the X and Y coordinates of a single intersection,
“*” Is used as a symbol for separating numerical values representing coordinates of two intersections. When the intersections (1, 3) and (4, 6) are continuously input, the output image processing circuit 12 sets a line segment having both ends of the intersections (1, 3) and (4, 6) as a diagonal line. The rectangular area is determined as the target area 76.

In step a5, the output image processing circuit 12
Waits for input of coordinates for determining a moving area. This moving area is an area in which the image in the target area is to be moved and displayed, and should be set in the output image. However, since the output image and the original image have the same coordinate system, Can be inferred from the image. The operator visually checks the superimposed image 75 printed on the recording paper 62, determines a moving region in the output image, and inputs coordinates representing the moving region. When the coordinates are input, the output image processing circuit 12
Determines the moving area based on the coordinates input by the processing unit 12b. When the movement area is determined, the process proceeds to step a6.

In the coordinate input operation, the operator first presses the area designation key 35 of the operation panel 5 and then inputs the coordinates by using the numerical key group 31 of the operation panel 5. The method of inputting the coordinates and the method of determining the moving area from the input coordinates are the same as those of the target area. For example, when inputting the intersections (1, 3) and (6, 6) successively, each key of the numerical key group 31 is pressed to select "1",
"#", "3", "*", "4", "#", "6" are sequentially input. At this time, the output image processing circuit 12 determines, as the moving area 77, a rectangular area having a diagonal line segment having the intersections (1, 3) and (6, 6) at both ends.

In step a6, the output image processing circuit 12
Examines the magnitude relationship between the target area 76 and the moving area 77 determined in steps a4 and a5 in the processing unit 12b. The magnitude relationship between these areas 76 and 77 can be examined in the X and Y directions by calculating the ratio of the width of the target area 76 and the moving area 77 in the X and Y directions. The width of the target area 76 in the X and Y directions is
If the width is less than the width in the X and Y directions, the process proceeds to step a7 to perform the enlargement movement processing in the X and Y directions. Target area 7
If the width of the moving area 6 in the X and Y directions is equal to or larger than the width of the moving area 77 in the X and Y directions, respectively, the process proceeds to step a8, and the X and Y reducing movement processing is performed.

In step a7, the output image processing circuit 12
Re-introduces the original image signal stored in the memory 13, performs the enlargement movement process, and generates an output image signal. Specifically, the processing unit 12b first obtains the magnification of the image deformation. The magnification is obtained individually in each of the X and Y directions. The magnification in the X direction is determined by the target area 76 and the moving area 7.
7 is the ratio of the width in the X direction, and the magnification in the Y direction is the ratio of the width of the target region 76 and the moving region 77 in the Y direction.
Next, in the original image signal, a target signal portion representing an image to be processed included in the target region 76 is extracted by the extraction unit 12c, and the processing unit 12b performs an interpolation process on the target signal portion to be described later. The target signal portion is processed so that the image included in 76 is enlarged by the magnification in the X and Y directions. Further, the combining unit 12d generates an output image signal so that the image represented by the processed target signal portion is displayed in the moving area. This output image signal is generated by, for example, replacing a signal portion representing a moving region in the signal representing a blank output image with the above-described processed target signal portion.
Alternatively, it is generated by replacing the signal portion representing the moving area in the original image signal with the processed target signal portion described above.

In step a8, the output image processing circuit 12
Re-introduces the original image signal stored in the memory 13, performs a reduction movement process, and generates an output image signal. The reduction movement processing is a processing operation similar to the enlargement movement processing, except that the target signal component is processed so as to reduce the image included in the target area 76 by the magnification in the X and Y directions. Are equal. Further, the operation of processing the target signal component so as to reduce the image can be realized by the same processing operation as the enlarging and moving process if the magnification is represented by a value less than 1. When setting the magnification in this manner, the width of the image included in the target area 76 in one of the X and Y directions is reduced by a processing operation similar to the enlargement movement processing, and the X of the image is reduced. The target signal portion can be processed so that the image is deformed by enlarging the width in any one of the directions Y and Y.

When the output image signal is generated in steps a7 and a8, the process proceeds to step a9. In step a9, the central processing circuit 7 determines whether or not the start key 33 of the operation panel 5 has been pressed. If not, the process returns from step a9 to step a2, and waits for an image processing operation to be instructed again. When the start key 33 is pressed, the process proceeds from step a9 to step a10, in which the central processing circuit 7 supplies the generated output image signal from the output image processing circuit 12 to the printing device 14, and prints it on recording paper. When the recording paper on which the output image is printed is ejected from the printing device 14, the process proceeds from step a10 to step a11, and the processing operation of the flowchart ends.

FIG. 8 shows a case where the intersections (1, 3) and (6, 3) are input in step a4 and the intersections (1, 3) and (6, 6) are input in step a5, as described above. FIG. 3 is a schematic diagram illustrating an output image 81 printed on a recording sheet 62 when an output image signal generated in FIG.
This output image 81 includes an elliptical image 82. The width of the image 82 in the X direction is twice as large as that of the image 72 of the original image 71, and the width in the Y direction is kept as it is. In addition, the center of the image 82 has moved along the X direction from the coordinate point where the center of the image 72 was located. This output image 81
Does not include the line segments 65 and 66.

With reference to FIG. 9, the interpolation method in the enlargement and reduction movement operations in steps a7 and a8 will be described. FIG.
(A) is a diagram showing a target image 91 in which a target signal component extracted from an original image signal is virtually visually displayed. A case will be described as an example where the target image 91 is reduced in the X and Y directions by a factor of 2/3.

First, the processing unit 12b calculates a plurality of line segments parallel to the X and Y coordinate axes 63 and 64 in the same coordinate system as the original image 71 by multiplying the interval between the images of the original image 71 by the reciprocal of the magnification. The grids 92 arranged at intervals obtained as described above are virtually superimposed on the original image. In FIG. 9A, the grid 92 is
It is represented by a two-dot chain line.

Next, a pixel is imagined on a grid point which is an intersection of line segments forming the grid 92, and the brightness of each pixel is obtained. When the grid points overlap the pixels of the target image 91, the brightness of the pixels assumed at the grid points is assumed to be equal to the brightness of the pixels of the target image 91. When the grid point and the pixel of the target image 91 do not overlap, the brightness of the pixel imagined at the grid point is interpolated by arithmetic processing using the brightness of the pixel of the target image 91 located around the grid point. Is done.

For example, the brightness of the pixel imagined at the grid point Q is interpolated by an arithmetic process using the brightness of the pixels P1 to P4 of the target image 91. At this time, the pixels P1 to P4
Among them, when the display color of at least one pixel is black, the pixel imagined at the lattice point Q is also a black pixel. When all the display colors of the pixels P1 to P4 are white, the pixel imagined at the lattice point Q is also a white pixel.

When the brightness of the pixels imagined for all the grid points is determined, the pixels at each grid point are arranged in a matrix at the same interval as the pixel arrangement of the original image. As a result, FIG.
A reduced target image as shown in FIG.
The target signal portion representing the reduced target image is configured by arranging data representing the brightness of the pixels imagined at the lattice points in a state corresponding to the pixel arrangement of the original image.

By such an interpolation method, the target image 9
1 can be reduced to obtain the signal portion. If the magnification is set to 1 or more by the above-mentioned interpolation method, the target image can be enlarged and its signal component can be obtained. Also,
By determining the interval of the line segment of the grid 92 by the magnification in each of the X and Y directions, even when the magnification in the X and Y directions is different,
By deforming the target image, its signal components can be obtained. As the interpolation method, a method other than the above-described method may be used.

In the image processing operation described above, not only the image deformation operation and the image movement operation can be performed simultaneously, but also the image deformation operation and the image movement operation can be performed individually. For example, in step a5 of the flowchart in FIG. 6, the coordinates (5,
When 7) and (7, 10) are input, an output image 84 as shown in FIG. 10 is obtained. At this time, the target area 7
6 and the moving area 77 are congruent, so the output image 84
The image 72 included in the original image 71 is included only while the position where the image is displayed is moved, and the shape is kept as it is.

As described above, when only the image moving operation is performed alone, the target area 76 and the moving area 77 are congruent. At this time, after extracting the target signal portion, the output image processing circuit 12 may generate an output image signal including the extracted target signal portion as it is without performing the interpolation process. At this time, the output image processing circuit 12
Does not perform the interpolation processing, so that the processing amount is reduced. Therefore, the processing amount and processing time of the entire image processing operation can be reduced.

Further, in the above-described image processing operation, when a plurality of moving areas 77 are designated for a single target area,
Not only can the original image 72 be deformed and moved, but also copied. For example, in step a5 of the flowchart in FIG. 6, as a coordinate for determining the movement area 77, a set of intersections (5, 0) and (7, 3) and an intersection (5,
When the combination of (7) and (7, 10) is input, an output image 86 as shown in FIG. 11 is obtained. At this time, since the target area 76 and the moving area 77 are congruent and two, the output image 86 includes the image 72 included in the original image 71.
Are moved and only the displayed position is included. In this case, the output image processing circuit 12 duplicates the extracted target signal portion to prepare two, and generates an output image signal so as to include the two target signal portions. Also, when the shapes of the plurality of target regions 77 are different from the target regions,
If the target signal portion after copying is deformed using the above-described enlargement and reduction movement processing, the image 72 of the original image is simultaneously copied with the image.
Can also be transformed.

Further, in the facsimile apparatus 1 described above, when a plurality of originals are prepared and a plurality of original image signals are generated, the image in the target area of each original image is included in a single output image. It can also be synthesized such that The image processing operation for performing the synthesis is similar to the image processing operation for moving and deforming the image described above, and differs from the operation in the flowchart of FIG. 6 in the following points, and the other operations are the same.

The difference is that the keys operated in steps a2 and a4 are changed from the enlargement / reduction key 37 to the edit key 38.
Is changed to In step a3, the above-described superimposed image signal is generated for each original image signal generated by reading each document, and is printed on recording paper. Therefore, the operator views each of the plurality of superimposed images, and determines the target area 76 for each original image.

When inputting coordinates for determining the target image 76, the operator sets the page designation key 35 following the edit key 38 and the area designation key 34 by a method corresponding to the page of the original image. After pressing, the numerical key group 31 is operated.
As a result, data representing the coordinates in the original image is added to the input coordinates. The page of the original image corresponds to, for example, the number of the original read on the original placing table 20 in order to generate an original image signal representing the original image. Attached.

Further, when performing the enlargement or reduction movement processing in steps a7 and a8, the synthesizing unit 12d regards the movement area 77 as being included in a single output image, and extracts the enlarged or reduced target signal portion. Synthesize all. This synthesizing operation is realized by, for example, replacing all target signal portions processed by the processing unit 12b with signal portions corresponding to the respective moving regions in an output image signal corresponding to a blank output image. Thus, the output image represented by the generated output image signal includes all the images included in the target area 76 in the plurality of original images. Therefore, an editing operation of enlarging or reducing images of a plurality of originals and arranging them in a single output image can be performed by a single image processing operation.

Further, in the facsimile machine 1 described above,
The black-and-white inversion operation of the display color of the original image and the erasing operation outside the area of the original image can be performed. This processing operation is performed by placing a document on the document table 20 and starting the processing operation. After performing the processing operations of steps a3 and a4 in the flowchart of FIG. Operate the instruction keys. Thus, the output image processing circuit 14 processes the original image signal in a state where only the target area 76 is designated. For example, in the black-and-white determination operation, the target area 76
The original image signal is processed so that, of the pixels in the above, a pixel whose display color is white is changed to a black pixel, and a pixel whose display color is black is changed to a white pixel. In addition, for example, in the out-of-region erasing operation, the remaining signal portion other than the target signal portion representing the target region 76 in the original image signal is rewritten to a signal representing a white pixel. As a result, the facsimile apparatus 1 described above can also perform processing operations that can be performed by designating only the target area 76.

Further, when a superimposed image is generated by the above-described image processing operation, not only a predetermined coordinate system image signal is synthesized with an original image signal to generate a superimposed image signal,
Other techniques may be used. For example, the line segments 65 and 66 may be printed by an operation similar to the operation of adding a ruled line to an image in parallel with the operation of causing the printing device 14 to print the original image. For example, when the printing device 14 can store the original image signal in the bitmap system, the line segments 65 and 66 are printed at the same time when the pixel of the predetermined address is printed.
When the printing apparatus 14 stores the encoded original image in a so-called page memory and decodes only the pixels to be printed, the printing apparatus 14 sequentially decodes the original image signal and synchronizes with the operation of printing the pixels. Then, the line segments 65 and 66 are printed periodically. Further, the method of generating and printing the superimposed image is not limited to the above-described method, and any method may be used as long as the method finally obtains the superimposed image of FIG.

The above coordinate system image is not limited to the lattice-like figure shown in FIG. 4, but the coordinate system of the original image is clearly specified so that the operator can recognize the coordinates of an arbitrary point in the original image. Any other figure may be used as long as the figure can be formed. For example, a figure composed of two line segments with scales representing the X and Y coordinate axes 63 and 64 of the coordinate system may be used. In this way, when comparing the coordinate system image with the graphic of only the coordinate axes and the coordinate system image with the lattice-like graphic as described above, the latter is farther from the origin of the coordinate system than the former. The coordinates of the point can be easily and reliably recognized. In the former, the number of line segments superimposed on the image of the original image is smaller in the former than in the latter, and the original image can be easily grasped when viewing the superimposed image.

As described above, in the facsimile apparatus described above,
An image processing operation that moves and deforms at least a part of the original image can be performed. In this image processing operation, the target area 76 and the moving area 77 are determined with reference to the superimposed image 75 printed on the recording paper 62. When each of the regions 76 and 77 is designated, the line segment 6
The coordinates of the intersections of 5, 66 are input using the numerical key group 31. Therefore, each of the regions 76 and 77 can be reliably specified without using a so-called coordinate detection device and a display device capable of displaying a cursor linked to a mouse.
Therefore, the above-described image processing operation can be performed without adding a display device and a coordinate detection device for visually displaying an image signal from the facsimile device 1.

Further, since the superimposed image 75 is generated based on the original image signal generated by reading the original, even when the original and the original image have the above-described misalignment, the overlapped image 75 is surely included in the original image. You can know the coordinates. Therefore, in particular,
It is preferably used in an image processing apparatus having an image input device that reads an original while moving and generates an original image signal.

In the image processing operation of the facsimile apparatus 1 described above, the operator prepares a transparent sheet on which the coordinate system image 61 is printed instead of viewing the recording paper 62 on which the superimposed image 75 is printed. The transparent sheet is superimposed on the recording paper 62 on which the original image 71 is printed and visually observed, and the target area 76
And the moving area 77 may be determined. This transparent sheet is a recording paper 62 on which a coordinate system image 61 shown in FIG.
And the recording paper 62 instead of the recording paper 62
The difference is that a film-shaped transparent sheet having the same light-transmitting property as that of No. 2 is used, and the positional relationship between the coordinate system of the coordinate system image 61 and the transparent sheet is the same. The transparent sheet may be provided in the facsimile machine 1 in advance, and is generated by printing the coordinate system image 61 on a translucent film-like sheet by the printing device 14 when performing an image processing operation. You may.

When performing an image processing operation using the transparent sheet, the transparent sheet is prepared in advance. The image processing operation is a similar operation to the flowchart in FIG. 6. Instead of generating and printing the above-described superimposed image in step a3, an additional image in which an alignment code is added to the original image 71 is generated. Print. This alignment code is the same as the original image 7
A code representing a predetermined reference coordinate point of the coordinate system set to 1. As the reference coordinate point, for example, a coordinate point that overlaps the four corners of the transparent sheet when the recording sheet on which the additional image is printed and the transparent sheet are overlapped so that the coordinate system is coincident is selected. Further, the reference coordinate point may be set to an arbitrary point, and a code representing the reference coordinate point may be printed on both the recording paper on which the original image is printed and the transparent sheet.

When the recording paper on which the additional image is printed is ejected from the printing device 14, the operator refers to the registration code to match the coordinate system between the recording paper and the transparent sheet prepared in advance. To overlap. Thereby, as when visually observing the recording paper on which the above-mentioned superimposed image is printed,
The coordinates in the original image can be known. Therefore, when inputting the coordinates for determining the target area 76 and the moving area 77 in steps a4 and a5, the coordinates of the intersection of the line segments 65 and 66 printed on the transparent sheet are input. Thus, an output image signal can be generated from the original image signal by the same operation as in steps a6 to a11.

Further, when performing the image processing operation using the above-mentioned transparent sheet, instead of generating the above-mentioned additional image and printing it on the recording paper,
Only the original image may be printed. At this time, when the recording paper on which the original image is printed and the transparent sheet are overlapped so that the outer circumferences thereof coincide with each other, the coordinate system of the original image and the coordinate system image can be matched.

When the image processing operation is performed using the transparent sheet as described above, the recording paper on which the original image is printed does not include the line segments forming the coordinate system image. Therefore, the recording paper on which the original image is printed can be diverted to another use. Therefore, the recording paper on which the original image is printed can be effectively used. Further, since it is not necessary to generate a superimposed image signal, the image processing operation can be simplified.

Further, in the facsimile machine 1 described above,
After the original image signal is generated first, processing is performed using the original image signal stored in the memory 13. Therefore, unlike a current image processing apparatus, it is not necessary to read a document a plurality of times. Also, when presenting the operator with the coordinate system of the original image using the superimposed image or using the original image and the transparent sheet, a new image is printed on the recording paper using the original image signal. Therefore, unlike the current image processing apparatus, there is no need to determine the coordinates to be input by referring to the original after being read. For these reasons, the number of times the document is placed on the document placing table 20 of the facsimile apparatus 1 a plurality of times can be reduced, and the labor of the operator can be simplified.

The image processing apparatus according to the present embodiment may be added to apparatuses other than the facsimile apparatus as long as the apparatus has the operating device 4, the image input device 11, and the printing device 14. For example, it may be added to a copying machine. The facsimile machine and the copying machine are already provided with a numerical key group 31 for inputting a telephone number or setting the number of copies in addition to the image input device and the printing device. Therefore, when the image processing apparatus of the present embodiment is added, the image processing apparatus can be formed only by adding the output image processing circuit 12. Therefore, it is possible to easily realize an image processing apparatus capable of performing the image processing operation for performing the deformation and movement of the image as described above.

The output image processing circuit 12 can be replaced with a virtual circuit realized by the arithmetic processing of the central processing circuit 7. Therefore, the facsimile apparatus and the copying machine having the image processing apparatus of the present embodiment can be realized only by adding the program for performing the above-described image processing operation to the conventional facsimile apparatus and the copying machine. Therefore, it can be realized more easily.

[0083]

As described above, according to the present invention, in the image processing apparatus, the original image and the coordinate system image are superimposed, printed, presented to the operator, and the coordinates in the original image are recognized. Further, according to the present invention, the image processing apparatus allows the operator to recognize the coordinates in the original image by superimposing the transparent sheet on which the coordinate system image is printed on the recording paper on which the original image is printed.
Further, in these image processing apparatuses, the operator inputs one coordinate and the other coordinate in the original image, and moves an image in a target area defined by the one coordinate to a moving area defined by the other coordinate. Accordingly, an image processing operation of moving an image in an original image by designating a target area and a moving area can be performed by an image processing apparatus including only a coordinate input unit having a configuration for inputting a numerical value representing a coordinate. It can be carried out. Therefore, the structure of the image processing apparatus can be simplified as compared with a conventional image processing apparatus that performs the above-described image processing operation. Further, when the recording sheet and the transparent sheet are overlapped, it is not necessary to combine the image signals of the original image and the coordinate system image, so that the structure and the processing procedure of the image processing apparatus can be further simplified.

Further, according to the present invention, the recording paper on which the original image is printed and the transparent sheet on which the coordinate system image is printed refer to the symbols representing the reference coordinate points respectively printed. Are superimposed. Thereby, when the operator obtains the above-mentioned pair of coordinates, it is possible to prevent an error in the coordinates.

Further, according to the present invention, the recording paper on which the original image is printed and the transparent sheet on which the coordinate system image is printed are overlapped so that the outer perimeters coincide. Thus, when the operator obtains the pair of coordinates described above, it is possible to prevent a coordinate error. Further, since no image other than the original image is printed on the recording paper, the recording paper can be easily diverted.

Further, according to the present invention, the image included in the target area can be deformed simultaneously with the movement of the image. Further, the operator simply inputs the pair of coordinates, and determines whether or not the image included in the target area is moved and deformed.
In addition, the magnification at the time of deformation can be input at a time.
Therefore, an instruction for moving and deforming the image can be issued by an easy method at the same time as an instruction for moving the image.

Further, according to the present invention, the magnification at which the image included in the target area is deformed is determined individually for each direction along each coordinate axis of the coordinate system. Therefore, it is also possible to perform irregular image deformation such that the magnification in each direction along each coordinate axis is different. Further, the magnification can be easily and reliably determined by the operator from the ratio of the width of the target area to the width of the movement area.

Further, according to the present invention, in the image processing apparatus, a plurality of original image signals are processed, the original image and the coordinate system image are superimposed and printed for each original image signal, and presented to the operator. Then, the coordinates in the original image are recognized. According to the present invention, in the image processing apparatus, a plurality of original image signals are processed, and a transparent sheet on which a coordinate system image is printed is superimposed on recording paper on which the original image is printed for each original image signal. Then, the operator is made to recognize the coordinates in the original image. further,
In these image processing apparatuses, a target signal portion representing a target region is extracted from each original image signal, and a plurality of extracted target signal portions are combined to generate a single output image.
Thus, an image processing operation of synthesizing a plurality of original images by designating a target area and a moving area is performed by an image processing apparatus including only a coordinate input unit having a configuration for inputting numerical values representing coordinates. be able to. Therefore, the image processing apparatus can be simplified as compared with a conventional image processing apparatus that performs the image processing operation. Further, when the recording sheet and the transparent sheet are overlapped, it is not necessary to combine the image signals of the original image and the coordinate system image, so that the structure and the processing procedure of the image processing apparatus can be further simplified.
