Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus used for an apparatus or a system for processing a digital image obtained by radiography such as X-rays.
The present invention relates to an image processing system, an image processing method, and a computer-readable storage medium storing processing steps for executing the image processing method and the image processing method.

2. Description of the Related Art Conventionally, for example, in radiography using medical X-rays, the intensity distribution of X-rays transmitted through the human body is converted into the fluorescence distribution of a fluorescent substance and directly projected onto a silver halide film, and the silver halide film is subjected to the same. It has a long history of developing.

[0003] In recent years, the intensity distribution of X-rays transmitted through a human body has been compared with the above-mentioned conventional technique by using electric signals (X-rays) of X-ray images.
Line image signals), and digitizing them to form digital images (X-ray digital images). As a method of acquiring an X-ray image signal, a method of forming a latent image of an X-ray intensity distribution on a stimulable phosphor as energy and reading out the energy as an X-ray image signal, or a method of obtaining a fluorescent distribution of the phosphor by X-rays is performed. There are a method of directly reading out as an X-ray image signal, a method of directly reading out an X-ray intensity distribution without using a phosphor, and the like.

[0004] By using the X-ray digital image, filing efficiency, practical use of remote diagnosis, medical treatment technology, and improvement of medical treatment efficiency can be achieved. Also, X
By digitizing the line image signal, various image processing becomes possible, and the image diagnosis method is also changing.

Under the above-mentioned background of the related art, for example, Japanese Unexamined Patent Publication No. 09-098970 discloses a large screen 2
An X-ray imaging apparatus using a two-dimensional solid-state imaging device has been proposed. According to this X-ray imaging apparatus, it is possible to acquire an X-ray digital image larger than a generally used film.

Further, in order to provide a large-screen two-dimensional solid-state image pickup device to the apparatus as in the above-mentioned X-ray photographing apparatus, large-scale equipment is required, and each generally used film of various sizes is required. It is also difficult to provide a two-dimensional solid-state imaging device having a size corresponding to
Only one type of two-dimensional solid-state imaging device is provided, and a necessary image area is digitally cut out from an X-ray image signal obtained from the two-dimensional solid-state imaging device after photographing.

An X-ray imaging apparatus equipped with a large-screen two-dimensional solid-state imaging device as described above originally realizes a filmless image diagnosis environment. Film output is often required.

On the other hand, DICOM (Digital I / O) is a standard protocol for transferring medical image information developed recently.
message Communication in Med
icine), the X-ray digital image data is
An imaging system that transfers images to laser imagers having various film sizes, such as 1 inch × 14 inches and 14 inches × 17 inches, so that the laser imagers can print out an X-ray digital image on film. is there. There is also an imaging system configured to transfer X-ray digital image data to not only one type (one manufacturer) of laser imagers but also a plurality of types (multiple manufacturers) of laser imagers.

Under the above-mentioned background of the related art, Japanese Patent Application Laid-Open No. 2000-115514 proposed by the present applicant has been proposed.
No. and Japanese Patent Application No. Hei 11-346224,
Images of various sizes acquired by a large-sized X-ray detector for a large-screen two-dimensional solid-state imaging device can be life-sized printed on an appropriate film, or multi-format output is possible. For example, JP-A-200
In No. 0-115514, for example, 11-inch × 14-inch and 14-inch × 17-inch, etc. are selected according to various film sizes, and an appropriate size is selected according to a portion to be output of an image, and an image on the film is appropriately selected. And output.
Japanese Patent Application No. 11-346224 has a means for accurately arranging a plurality of images in the above-described various film sizes, and has a function of outputting a plurality of images to one film.

[0010]

However, the conventional X-ray imaging apparatus as described above has the following problems.

First, for example, from the standpoint of primary screening and reducing the load of doctors interpreting X-ray images, it may be required to realize not only life size printing but also reduced printing.

[0012] "Realization of life size printing" here
For example, when the pixel size of the X-ray detector is 160 μm and the spatial resolution of the laser imager is 80 μm, if the image data is enlarged twice, life size output can be performed. means. Also,
"Realization of reduced printing" means that, under the above-mentioned conditions, the image data is printed out at least one time and smaller than two times.

[0013] In the above-mentioned "realization of reduced printing", "1 or more times" means that the amount of data transferred (sub-sampling) by a normal laser imager is reduced (sub-sampling) according to a standard such as FDA. This is because it has not been recognized. However, there is no limitation as long as the standard permits.

Therefore, in particular, the following problems (1) to (3) can be cited as problems relating to reduced printing.

(1) In general, image data cannot be specified by the reduction ratio at the time of printing, but can be specified only by the number of divisions (1 row, 2 columns, etc.) at the time of printing. That is, the reduction ratio can be specified only by the corresponding format division number.

(2) The fact that “the reduction ratio can be specified only by the corresponding number of format divisions” in the above (1) means that 512 × 512 pixels are always present as in an X-ray CT output image. Is suitable for reproducing a plurality of images having the same image size on one film.
In imaging in which the X-ray irradiation threshold is narrowed to various sizes with a line detector, large and small images to be output are mixed, so that image data having mixed cutout sizes is converted to one film. When arranging them on one film when arranging them on the top, the reproduction magnification is differently reproduced depending on the cutout size, and an image having a different magnification is reproduced on one film, and the cutout size is different. It is not suitable for printing all images at the same magnification.

(3) When image data is transferred to a plurality of laser imagers via a network or the like, the laser imager may have different laser imagers depending on the difference in drawing performance between types (between manufacturers) and especially on the difference in the effective drawing area. The size of the drawing on the film may be different for each imager. In this case, printing at the same reduction rate becomes impossible.

Accordingly, the present invention has been made to eliminate the above-mentioned drawbacks, and has been made capable of outputting an image at a desired reduction ratio and outputting a multi-format image at a desired reduction ratio. And an image processing apparatus, an image processing system, an image processing method, and a processing step for performing the same, which guarantee that an image can be output at a desired reduction ratio even with different types of output devices or systems. It is an object of the present invention to provide a computer-readable storage medium.

<Operations Characteristic of X-Ray Imaging System 100> FIG. 6 shows operations of the imaging system 100 before imaging.

Step S501: The user operates the control device 1
04, information on the subject 102 (patient name and patient ID)
Etc.). Step S502: The user
In the control device 104, information on the imaging region (front of the chest, etc.) of the subject 102 is input.

The information input in steps S501 and S502 is not limited to the case where the information is input in the photographing system 100. For example, the information input through the network 106
RIS (Radology Information)
System) and HIS (Hospital Info)
The system may be configured to be input from an ordering server such as an operation system, or may be configured to be input by a magnetic card, a barcode, or the like.

Step S503: The control device 104 determines whether or not the setting for performing the printer transfer has been made to the photographing system 100.

Step S504: If the result of determination in step S503 is that printer transfer has not been set,
The control device 104 causes the photographing system 100 to transition to a photographable state. After that, the process ends.

Step S505: If the result of determination in step S503 is that printer transfer has been set, the control device 104 determines whether or not the photographing system 100 has been set to perform reduced printing. Specifically, as described above, the magnification setting unit 204 obtains the setting information by the GUI 400 in FIG. Therefore, the control device 104 operates the input unit 406 of the setting information.
The above determination is made based on the information of (input unit for setting whether or not to perform reduced printing).

Step S506: If the result of determination in step S505 is that reduction print has not been set,
The control device 104 sets the same size print (life size print) for the photographing system 100, proceeds to the above-described step S504, and transitions the photographing system 100 to a photographable state. After that, the process ends.

Steps S507 and S508: Step S
If the result of determination in 505 is that reduction printing has been set, the control device 104 performs printing at the specified reduction ratio based on the transfer destination information set for the imaging region input in step S502. It is determined whether or not it is possible. Specifically, as described above, the setting information by the GUI 300 of FIG.
That is, performance information of the transfer destination is obtained. Further, setting information by the GUI 400 of FIG.
That is, information such as the transfer destination and the reduction ratio for each imaging part or imaging technique can be obtained. Then, the reproduction determination unit 205 can reproduce the image based on the information (reduction printing is possible).
Is determined. Therefore, the control device 104
Determines whether or not printing can be performed at the currently set reduction rate based on the performance of the scheduled transfer destination based on the determination result of the reproduction determination unit 205.

Step S509: Steps S507 and S507
If the result of determination in 508 is that printing is not possible, the control device 104 calculates the maximum reduction rate based on the performance information of the transfer destination obtained in steps S507 and S508.

More specifically, the calculation of the maximum reduction ratio is performed by the reproducible magnification calculator 207 as follows. First, the pixel size of the image sensor 114 of the X-ray detector 103 is set to Px [μm], the laser imager 107 is set as a transfer destination, and its spatial resolution is set to Py.
When [μm] is set, the relationship of “Px> Py” is generally satisfied. For example, Px = 160
[Μm] and Py = 80 [μm], the life size is obtained by interpolating and expanding the image data acquired by the X-ray detector 103 so that Px / Py times = 160/80 = 2 times. Printing becomes feasible.

In the present embodiment, it is assumed that the relationship “Px / Py ≦ 1” is satisfied, that is, the case where the sub-sampling of the image data obtained in the X-ray imaging system 100 is not considered, Maximum reduction ratio S in this case
Can be calculated from the pixel size of the image sensor 114 by Px and the spatial resolution Py of the transfer destination by the calculation of S = C [Px / Py]. "C []" in the above equation
Indicates that a round-up operation is performed in consideration of a risk that printing cannot be performed due to a calculation error.

In this embodiment, the sub-sampling is not taken into consideration. For example, when the transfer destination is the laser imager 107, the data amount is reduced as a laser imager according to the FDA standard or the like. This is because it has not been done. However, this is not limited if the standard permits.

Step S510: After the processing of step S509, the control device 104 presents to the user information indicating that resetting is to be performed based on the maximum reduction rate S calculated as described above. The presentation to the user here is made by the warning unit 20.
6. As a result, the user resets using the GUI 300 in FIG. 4 or the GUI 400 in FIG. 5 according to the presentation information. So, for example,
Even if the user changes the transfer destination and forgets to reset the reduction ratio for the imaging region, it is possible to reliably prevent erroneous operation. Step S510
After the process of step S50, the control device 104
Then, the process proceeds to step S4, where the image capturing system 100 is shifted to a state in which image capturing is possible. After that, the process ends.

On the other hand, if the result of determination in steps S507 and S508 indicates that printing is possible, control device 104
The process directly proceeds to step S504 described above, and the imaging system 100 is shifted to a state in which imaging is possible. After that, the process ends.

FIG. 7 shows the photographing system 100 after image acquisition.
This shows the operation of.

Step S601: The control device 104
Image cutout position information for the image data of the subject 102 obtained by the / D converter 116 is obtained. The image cutout position here may be obtained by directly using the irradiation field recognition result, or may be obtained by an image cutout position designated by the user.

Step S602: The control device 104 determines whether or not the setting for performing the printer transfer has been made to the photographing system 100.

Step S603: If the result of determination in step S602 is that printer transfer settings have not been made,
The control device 104 causes the imaging system 100 to transition to a printer transfer option change waiting state. After that, the process ends.

Step S604: If the result of determination in step S602 is that printer transfer has been set, the control device 104 specifies the performance information of the transfer destination and the designation of the film and multi-format print specified for the imaging site. Gather information such as presence or absence. Specifically, as described above, the transfer destination performance acquisition unit 202 performs G
The setting information by the UI 300, that is, the performance information of the transfer destination is obtained. Further, information such as the presence / absence of designation of a film and a multi-format print is obtained in the reproduction supplementary information input unit 203. Therefore, the control device 104 collects such information.

Step S605: The control device 104 determines whether or not the photographing system 100 is set to perform reduced printing. Specifically, as described above, the magnification setting unit 204 obtains the setting information by the GUI 400 in FIG. Therefore, the control device 104
Performs the above-described determination based on the information of the setting information input unit 406 (input unit for setting whether or not to perform reduced printing).

Step S606: If the result of determination in step S605 is that reduction print has not been set,
The control device 104 sets the same size print (life size print) for the photographing system 100, proceeds to the above-described step S603, and transitions the photographing system 100 to a printer transfer option change waiting state. After that, the process ends.

In the life size print setting process in step S606, for example, it is determined whether or not life size printing is possible. If life size printing is not possible, a warning is output to that effect. In addition, processing such as determining the size of the image cut-out area is executed, but since the purpose is different from the configuration characteristic of the present invention, detailed description thereof is omitted.

Step S607: If the result of determination in step S605 is that reduction printing has been set, the control device 104 determines whether or not multi-format printing has been designated based on the information obtained in step S604. .

Step S612: If the result of determination in step S607 is that multi-format printing is specified, the control device 104 sets the number of effective pixels of the transfer destination image output destination (film or the like) to a pseudo small value. That is, the control device 104 sets the number of pixels set by the input units 304 and 305 in the GUI 300 of FIG.

Steps S608 and S609: After the processing of step S612 or when multi-format printing is not designated by the discrimination of step S607, the control device 104 transmits the performance information of the transfer destination and the information of the X-ray detector 103. Then, based on the number of pixels in the image cutout area indicated by the image cutout position information acquired in step S601, it is determined whether or not printing at the specified reduction ratio is possible. Here, the determination processing in steps S608 and S609 is the same as the determination processing in step S507 shown in FIG. 6 described above.

First, the pixel size of the image data obtained by the X-ray detector 103 is set to Px [μm] and the transfer destination (here,
The pixel size of the laser imager 107) is Py
[Μm], the width and height of the effective pixel area of the image output destination (film) are Wp, Hp, and the width and height of the image cutout area indicated by the image cutout position information acquired in step S601 are Wi, As Hi, the designated reduction ratio is Ss.

For example, Px = 160 [μm], Py = 8
0 [μm], Wp = 4096, Hp = 5120 (film size is 14 × 17), film orientation is landscape (landscape), multi-format 1 line 2
In the case of a row, an area where one image can be drawn (effective pixel area of the film) is an area indicated by a width Wp and a height Hp of Wp = 5120/2 = 2560 Hp = 4096/1 = 4096. Here, for the sake of simplicity, no margin is added between adjacent images.

Ss = 50 [%], Wi = Hi = 2
In the case of 688, the maximum reduction rate calculated from the pixel size Py of the laser imager 107 and the pixel size Px of the X-ray detector 103 is: 2048 × 80 × 100 / (2688 × 160) = 3
8.09 [%], and the result of this calculation is the designated reduction rate Ss = 50
It exceeds [%]. If this is the case,
At the current designated reduction rate and the size of the image cutout area, it is determined that reduced printing is not possible.

Step S610: steps S608, S
If the result of determination in 609 is that printing is not possible, the control device 104 calculates the size of the largest possible image cut-out area at the specified reduction ratio using the information in steps S608 and S609.

More specifically, for example, in steps S608 and S608,
In the case of the conditions described in the example of 609, Px = 16
The size (width Wi ′, height Hi ′) of the maximum image cut-out area when 0 [μm], Py = 80 [μm], and Ss = 50 [%] is such that the currently specified film is vertically long. As a result, there is a lateral limitation. Finally, for the width Wi ′, Wi ′ = 2560 × 80 × 100 / (160 × 50) =
It is calculated by an operation of 2560 pixels. On the other hand, for the height Hi ′, Hi ′ = 4096 × 80 × 100 / (16 g × 50) = 4096> Hi = 2688, and the size of the image cut-out area from the current reduction ratio is not restricted. Become. Therefore, a 14 × 17 landscape, multi-format one row and two columns, 50 [%]
With the reduction ratio of, the size of the image cutout area that can be reduced and printed is Wi '= 2560 Hi' = 2688.

Step S611: After the processing of step S610, the control device 104 outputs information indicating that the image is to be reset according to the size (width Wi ', height Hi') of the image cutout area calculated as described above. To the user. The presentation to the user here is performed by the warning unit 206. As a result, the user resets using the GUI 300 in FIG. 4 or the GUI 400 in FIG. 5 according to the presentation information. After the processing in step S611, the control device 10
In step S603, the process proceeds to step S603, where the imaging system 100 is shifted to a printer transfer option change waiting state. After that, the process ends.

On the other hand, if the result of determination in steps S608 and S609 indicates that printing is possible, control device 104
The process directly proceeds to step S603, and the imaging system 100 is shifted to a printer transfer option change waiting state. After that, the process ends.

FIG. 8 shows the operation of the X-ray imaging system 100 after the imaging of the subject 102 has been completed. For example, one or a plurality of captured images are obtained by one examination of the subject 102, and the following processes are performed on the captured images. Further, the processing is performed by the control device 10
4 is executed by the image arrangement information determining unit 209 realized by the control of FIG.

Steps S701 and S702: When the pre-print processing (main processing) is started (step S701), first, it is determined whether or not the target image data of the subject 102 obtained by the A / D converter 116 is to be reduced and printed. Determine.

Step S703: As a result of the determination in step S702, if reduced printing is not to be performed, life size printing (actual size printing) processing of the target image data is performed (step S703).

Step S704: It is determined whether or not this processing has been performed on all the images obtained by the inspection. If the result of this determination is that there is an unprocessed image, the flow returns to step S702 again. The subsequent processing steps are repeatedly executed. On the other hand, when the processing on all the images is completed, the print processing in step S710 is executed.

Step S705: As a result of the discrimination in step S702, if reduced printing is to be performed, it is determined whether or not to perform reduced printing as a multi-format.

Step S706: If the result of determination in step S705 is that it is not multi-format printing, it is set so that only the target image is output on one film. Thereafter, the process proceeds to step S704 described above, and it is determined whether or not this process has been performed on all images obtained by the inspection. If the result of this determination is that there is an unprocessed image, the process returns to step S702 again. The processing steps after the return are repeatedly executed. On the other hand, when the processing on all the images is completed, the print processing in step S710 is executed.

Step S707: If the result of determination in step S705 is that the print is multi-format print, other image data currently designated as reduced print exists, and the number of multi-format divisions for the image data is equal, and It is determined whether a reduction ratio is set for the image data. As a result of this determination, if even one of the above conditions is not satisfied, the process proceeds to step S706 described above, and a setting is made so that only the target image is output to one film. Thereafter, the process proceeds to step S704 described above, and it is determined whether or not this process has been performed on all images obtained by the inspection. If the result of this determination is that there is an unprocessed image, the process returns to step S702 again. The processing steps after the return are repeatedly executed. On the other hand, when the processing on all the images is completed, the print processing in step S710 is executed.

Step S708: If the result of determination in step S707 is that there is another image data satisfying the above conditions, the number of divisions and the reduction ratio of the multi-format for the image data are changed to the multi-format division for the target image data. It is determined whether they are equal to the number and the reduction ratio. If the result of this determination is that the number of divisions and the reduction ratio of the multi-format are not equal, the process proceeds to step S706 described above, and a setting is made so that only the target image is output on one film. Thereafter, the process proceeds to step S704 described above, and it is determined whether or not this process has been performed on all images obtained by the inspection. If the result of this determination is that there is an unprocessed image, the process returns to step S702 again. The processing steps after the return are repeatedly executed. On the other hand, when the processing on all the images is completed, the print processing in step S710 is executed.

Step S709: If the result of the determination in step S708 is that the number of divisions and the reduction ratio of the multi-format with respect to each other are the same, these image data are set to be output on the same film. Thereafter, the process proceeds to step S704 described above, and it is determined whether or not this process has been performed on all images obtained by the inspection. If the result of this determination is that there is an unprocessed image, the process returns to step S702 again. The processing steps after the return are repeatedly executed. On the other hand, when the processing on all the images is completed, the print processing in step S710 is executed.

As described above, in the present processing, when the multi-format is designated, even if the number of divisions is the same, if the reduction ratio is different, a print is output to another film. It is possible to reliably prevent images having different ratios from being mixed, and to surely prevent confusion when the user observes the film.

In the print processing in step S710, processing such as image processing by the image processing unit 208, image arrangement by the image arrangement information determination unit 109, and image transfer to the set transfer destination by the image transfer unit 210 are performed. Regarding the image arrangement, for example, Japanese Patent Application Laid-Open
This can be realized by using -115514 or the like . By using this, it is possible to arrange and print a plurality of image data on one film.

As described above, in the X-ray imaging system 100 of the present embodiment, when the acquired image is printed at a size smaller than the life size print, the reduced print can be performed both before and after the image capture. Is accurately determined, and as a result of the determination, if reduced printing cannot be performed, a warning is accurately output to the user. It is possible to reduce the amount, and even when printing on different films, it is possible to print at the same reduction rate, and it is assured that reproduction at the same size is performed even when follow-up observation is performed. Further, in the case of performing reduced printing and multi-format printing, an image having the same reduction ratio is always printed. For example, when a user observes an image on a film, an image having a different reduction ratio is used. Since there is no danger of contrast, erroneous diagnosis or the like can be reliably prevented.

(Second Embodiment) In the first embodiment, multi-format printing is specified, and each image having the same number of divisions and reduction ratio is output on the same film. However, in reality, it is not necessary to strictly implement the configuration of the first embodiment depending on the relationship between the body position of the subject 102 at the time of imaging and the X-ray source 101 and the like.

That is, when a plurality of images are output on one film in the multi-format printing, a certain width may be provided for the reduction ratio for each image. Thus, for example, when the normally used laser imager is periodically inspected, or when the setting is changed, the maximum reduction rate differs, so when reprinting an image for follow-up observation, etc., The operation of resetting the reduction ratio again for each acquired image can be reduced.

(Third Embodiment) In the first embodiment, the performance information of the transfer destination, the information of the X-ray detector 103, and the step S60 in step S609 of FIG.
Based on the number of pixels in the image cut-out area indicated by the image cut-out position information obtained in step 1, it is determined whether or not printing at the designated reduction ratio is possible. Has been configured to change the size of the image cut-out area by changing the reduction ratio for the user, but the present invention is not limited to this. For example, the configuration may be configured as follows.

For example, as shown in FIG.
As steps after step 09, the following steps S901 to S901 are performed.
It is configured to execute S904. In the flowchart of FIG. 9, steps that execute the same processes as those in the flowchart of FIG. 6 are denoted by the same reference numerals, and detailed description thereof will be omitted.

Step S901: If the result of determination in step S609 is that reduced printing is not possible, the controller 1
In step 04, the user is warned of this, and the subsequent setting request from the user is obtained.

More specifically, for example, as shown in FIG.
The UI 800 is presented to the user. GUI8 of FIG. 10 above
In 00, a button 801 for instructing to change the cutout size while fixing the reduction ratio and a button 802 for instructing to change the reduction ratio while fixing the cutout size are provided. Note that if the cutout size is fixed, a reduction ratio that cannot be realized may be calculated. In this case, the button 802 is set to the operation disabled state.

Steps S902 to S904: control device 1
04 indicates that the user desires using the GUI in FIG.
It is determined whether to optimize the size of the image cut-out area or optimize the reduction ratio (step S902). As a result of the determination in step S902, when optimizing the size of the image cutout area, the control device 104 acquires and sets the size of the maximum image cutout area from the current reduction ratio, and proceeds to the next step S603. . On the other hand, as a result of the determination in step S902, if the reduction ratio is to be optimized, the control device 104
The maximum reduction ratio is obtained and set from the size of the current image cutout area, and the process proceeds to the next step S603.

Therefore, according to the present embodiment, for example, in order to perform follow-up observation, the reduction ratio is not mainly considered, but the size of the image cutout region is mainly considered. In other words, it is possible to cope with the case of observing the external appearance with a film as small as possible.

An object of the present invention is to supply a storage medium storing program codes of software for realizing the functions of the host and the terminal according to the first to third embodiments to a system or an apparatus, and to provide the system or the apparatus with It is needless to say that the present invention is also achieved when the computer (or CPU or MPU) of the apparatus reads out and executes the program code stored in the storage medium.

[0130]

As described above, according to the present invention, when a photographed image (radiation image or the like) is enlarged or reduced for reproduction (print output on a film or the like), an image cut out from the photographed image can be reproduced. In the case of reproduction, it is necessary to accurately determine whether or not the image can be reproduced at the enlargement or reduction magnification or the image cutout size before the reproduction. If the reproduction cannot be performed, an appropriate warning is issued to the user. Since output is performed, useless work such as adjusting the reduction ratio after actual reproduction can be omitted. In addition, since it is configured to determine whether the image can be reproduced based on the performance of the transfer destination or the like, the image can be reproduced at the same reduction rate even when the image is reproduced at a different transfer destination.

Further, when the warning is issued, information such as the reproducible magnification and the image cutout size is presented to the user, so that the user can easily reproduce and obtain the desired magnification and image cutout size. Can be set, the image can be reproduced at the same reduction rate even when the image is reproduced at different transfer destinations, and it can be ensured that the image is reproduced at the same size even when the follow-up observation is performed.

Further, when the same magnification or an image within an arbitrary range is arranged on the same reproduction medium, for example, even if reduced printing and multi-format printing are performed, the same size is required. Since the image having the reduced ratio of is printed out, there is no danger of comparing images having different reduced ratios during observation, and erroneous diagnosis in image diagnosis can be reliably prevented.

Therefore, it is possible to reproduce an image at a desired appropriate magnification and image cutout size, and to reproduce an image of a multi-format or the like at a desired appropriate magnification and image cutout size. It is also possible to reproduce an image at a desired appropriate magnification and image cutout size at the transfer destination.
