Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an image processing apparatus and method for appropriately controlling an image size when outputting.

[0002]

2. Description of the Related Art In X-ray photography for medical diagnosis, a film screen system combining an intensifying screen and an X-ray photographic film is generally used. According to this method,
X-rays that have passed through the subject contain internal information of the subject, which is converted into visible light in proportion to the intensity of the X-rays by the intensifying screen, exposing the X-ray photographic film, and forming an X-ray image on the film I do.

In recent years, X-rays have been converted to X-rays by phosphors.
The light is converted into visible light proportional to the intensity of the line, which is converted into an electric signal using a photoelectric conversion element.
X-ray digital imaging devices that perform digital conversion by D conversion have begun to be used.

[0004]

However, the sensor area of an X-ray digital imaging apparatus may be larger than a film screen system in some cases. For example, such as CXDI (trademark) manufactured by Canon Inc.
7 inch (43 cm) square. On the other hand, commercially available film sizes are only predetermined sizes such as 14 × 17 inches, 14 × 14 inches, and 10 × 12 inches. Therefore, when printing on a commercially available film, there is a problem as to which area is cut out from a 17-inch square image and which film is put out.

[0005] On the other hand, many commercially available image viewers often have a predetermined image size, and in particular, the maximum size is often determined. For example, in a commercially available diagnostic viewer, 2048x2048 pixels is the largest image size that can be accepted. Therefore, even in the case of outputting for a purpose other than the film, the same problem as that of the film occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to provide a plurality of output sizes determined in advance according to a portion to be output of an image to be output. An object of the present invention is to make it possible to select and output an output size, and to appropriately output an image to an existing medium or a viewer without losing information.

[0007]

The image processing apparatus of the present invention for achieving the above object has, for example, the following arrangement. That is, an area to be output from the image represented by the image data is specified as an output image, and an acquisition unit that acquires the size of the output image, and a preset area based on the size of the output image acquired by the acquisition unit. Selecting means for selecting one image output size from among a plurality of types of image output sizes, and arrangement determining means for determining the arrangement of the output image in an output area having the image output size selected by the selecting means. A display unit for displaying based on the arrangement state determined by the arrangement determination unit; and an instruction to change the arrangement state displayed by the display unit, changing an arrangement state of the output image in the output area. Changing means.

Further, according to the present invention, there is provided an image processing method realized by the above image processing apparatus.

According to the present invention, there is provided a storage medium for storing a control program for causing a computer to implement the image processing method.

[0010]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. In the following embodiment, an embodiment in which the image processing apparatus of the present invention is applied to an X-ray image reading apparatus will be described.

FIG. 1 is a block diagram showing the configuration of the X-ray image reading device. The operator places the subject 100 to be photographed between the solid-state imaging device 101 and the X-ray tube 102. Next, a part to be imaged is selected using a user interface (consisting of the display IF unit 119, the display 120, the keyboard and the mouse 121). By this operation, the arrangement mode of the subject, that is, whether to perform PA (emission from the back to the front) shooting or AP
The image reading control unit 113 applies a voltage to the solid-state imaging device 101 using the solid-state imaging device driving control signal, and simultaneously instructs whether to perform imaging (emitted from the front surface to the back surface). Prepare for the image to be entered at any time.

Next, the operator moves the X-ray tube 102 to an appropriate distance with respect to the solid-state imaging device 101. At this time, the distance (distance signal) between the solid-state imaging device 101 and the X-ray tube 102 is input to the image reading control unit 113 using the distance measuring unit 106.

Next, the operator uses the aperture instruction unit 108 to input X
The aperture of the line is adjusted so that the target part of the subject to be photographed is included. Aperture signal 1 from aperture instruction unit 108
Are transmitted to the image reading control unit 113, the aperture signal 2, the X-ray generator control unit 109, and the aperture signal 3, and the opening and closing of the X-ray aperture 105 are controlled. This X-ray aperture 105
It is a rectangle, and it is possible to adjust the opening and closing amounts in both the vertical and horizontal directions. The X-ray aperture 105
Is properly illuminating the site of the subject 100,
It can be adjusted using lamp light.

Exposure button 110 applies X-ray
Trigger to generate a line. The exposure signal 1 generated from the exposure button 110 is input once to the image reading control unit 113 in the image reading device 111. Image reading control unit 1
In 13, after confirming whether or not the solid-state imaging device 101 is in a state in which the input X-ray can be imaged, based on a state of a drive notification signal from a unit including the solid-state imaging device 101,
An exposure permission signal is generated. The irradiation permission signal turns on the irradiation permission switch 114 and changes the irradiation signal 1 to the irradiation signal 2
Is conducted. For the exposure signal, a switch called an exposure button second switch is used (the exposure button of the X-ray generator is pressed in two steps, and the first step (fast switch) is a switch to the X-ray generator). The second stage (second switch) is for applying X-rays to apply a voltage).

The exposure signal 2 is transmitted to the X-ray generator control unit 109
Is input to The X-ray generator control unit 109 outputs an irradiation signal 3 as soon as preparation for X-ray irradiation is completed, and causes the X-ray tube 102 to generate X-rays. After being exposed, the X-ray transmission lines are input as an image to the solid-state imaging device 101 via the grid 104 and the scintillator 103.

The solid-state imaging device 101 generates an electric signal corresponding to the image, reads out the electric signal, and reads out the electric signal from the A / D converter 10.
The image data is digitized by 7 and transferred to the image reading control unit 113. The image reading control unit 113 is managed by the CPU 112. The CPU 112 also has a RAM 11
5, ROM 116, LAN / IF 117, DISK / I
F118, nonvolatile storage device 122, user IF unit 11
9 is connected via a bus.

In the present embodiment, a hard disk is used as an example of the nonvolatile storage device 122. In addition, the user IF unit 119 includes a display 120
And a keyboard and mouse 121 to provide an interface with the user. An image (digital image) input from the A / D converter 108 to the image reading control unit 113 is temporarily placed on the RAM 115, and the CPU 112 performs various processes described later.

FIG. 2 is a block diagram for explaining the irradiation field area arrangement and the sensor position marking processing. Note that the process shown in FIG. 2 is realized by the CPU 112 executing a control program stored in the ROM 116.

The irradiation field recognition unit 201 performs irradiation field recognition on the photographed image and calculates an irradiation field area. There are several methods for recognizing the irradiation field, and for example, the method proposed in Japanese Patent Application No. 10-243020 by the present applicant can be used. In brief, a first-order difference value of the density value representing each of the three rectangular regions arranged in parallel is calculated between adjacent rectangular regions, and the calculated 1st difference value is calculated.
Calculating means for calculating a secondary difference value from the secondary difference value; calculating area determining means for determining three regions of the square; storage means for storing the secondary difference value calculated by the calculating means; With the configuration including the determination unit that determines one end point of the irradiation region from the secondary difference value stored in the storage unit, the irradiation region is easily and accurately extracted from the radiation image. Irradiation field recognition unit 2
When the irradiation field is recognized by 01, the result (irradiation field area information) is provided to the display image processing unit 202.

The display image processing unit 202 performs image processing based on the photographed image and the irradiation field area information from the irradiation field recognition unit 201 so that the inside of the irradiation field area has an appropriate contrast. , A reduced image for display is generated. Note that this processing is out of the spirit of the present embodiment, and thus will not be described in detail here.

On the other hand, the irradiation field area information indicating the irradiation field recognition result of the irradiation field recognition section 201 is stored in the irradiation field area arrangement calculation section 20.
3 is also provided. The irradiation field area arrangement calculation unit 203 is based on some preset output sizes,
Calculate the arrangement of the irradiation field area. Although the calculation algorithm will be described later, the output of the irradiation field region arrangement calculation unit 203 is arranged so that the irradiation field region of the original captured image is included in the selected output size.

FIG. 3 is a diagram showing an example of the arrangement of the irradiation field area. Here, a large size (35 cm square) output size (film area) is selected, and the irradiation field area is arranged so as to fit within this output size.

FIG. 4 is a diagram for explaining a preset output size. In the present embodiment, five designated sizes are prepared as shown in FIG. 4, and the irradiation field region arrangement calculation unit 203 selects an appropriate one from these output sizes. For example, in FIG. 3, a large size is selected from among the designated sizes. This size is optimal in that a larger film size has many surplus areas (excess areas), and a smaller film size does not cover the irradiation field area.

Returning to FIG. Irradiation field area arrangement calculation unit 20
In 3, it is calculated where the irradiation field area is arranged at the designated size, and the result is calculated based on the display image rotation inversion unit 20.
4 provided. The display image rotation inversion unit 204 performs rotation and inversion of the reduced display image based on the rotation and inversion designated values instructed at the time of shooting. For example, as shown in FIG. 8, when the operator takes an image of a subject with PA (from back to front), in this embodiment, if the operator simply displays a captured image due to the influence of the reading direction of the sensor, it is possible to obtain an image that is normally viewed by a doctor. On the contrary, for example, the heart is displayed on the left side. Therefore, P
In the A shooting, the left and right inversion is required when displaying an image. In addition, the rotation processing is intended to correct the possibility that the image is turned upside down depending on the direction of the subject's head on the bed. In addition, since PA and AP imaging exist in the bed, the reversal process is required for the same reason as described above.

In the display image rotation reversing unit 204,
Regarding the irradiation field area arrangement coordinates, the coordinate system conversion must be performed in consideration of the display reduction ratio, the previous rotation, and the inversion. Then, the result is transmitted to the overlay unit 205.

The overlay unit 205 performs a rectangular overlay display on the reduced, rotated, and inverted irradiation field area arrangement coordinates on the rotated, inverted, reduced display image. Then, the display unit 206
Displayed to This display will be described later with reference to FIG.

If the irradiation field area arrangement calculation unit 203 cannot accommodate the entire irradiation field area even with the maximum output size, it notifies the operator that the irradiation field area exceeds the output size. . In this embodiment,
This warning is issued on the display unit 206. In this case, the operator can perform the following three operations.

(1) Reduce the image inside the irradiation field area,
Keep within the maximum output size. In this case, the output image does not have the life size, and is output smaller than the life size. FIG. 5 is a diagram illustrating a process of reducing the irradiation field. In FIG. 5, a film area 501 indicated by a broken line is relatively large with respect to an irradiation field area 503. That is, in the actual processing, the irradiation field area 503 is reduced so as to fit in the film area 501, so that the film output is smaller than the life size. In addition,
Reference numeral 502 denotes a sensor area, which is an area where the solid-state imaging device 101 can input an image.

(2) The range of the irradiation field area is reduced to a range that can be accommodated in the film area. FIG. 6 is a diagram illustrating a process of reducing the range of the irradiation field region. In this process, as shown in FIG. 6, the portion of the irradiation field area 603 that protrudes from the film area 601 is excluded and output as the exclusion unit 604.

(3) The irradiation field region is limited and designated by the operator. FIG. 7 is a diagram illustrating a process of limiting an irradiation field region by an operator. In this case, the operator uses the mouse
A diagonal vertex of a rectangle to be an irradiation field area is specified. In FIG. 7, the irradiation field region 703 is determined by the operator instructing the positions indicated by two crosses, and is used instead of the irradiation field region obtained by the irradiation field recognition unit 201. That is, when the operator specifies the irradiation field area 703 smaller than the film area 701, the above-described normal processing is performed. In this example, the large-angle size including the irradiation field area 703 is specified. When the size is specified, a size with a small remaining amount is automatically selected.

The change of the arrangement processing as described above is performed by the instruction unit 2
07 (in this case, the mouse and the user IF unit 119) is instructed to the irradiation field area arrangement calculation unit 203, and the above-described exceptional operation is achieved.

By the way, when the operator shoots the subject with the setting to be shot by PA (from back to front), when deciding the actual direction of the patient, AP (front to back) is inevitably determined according to the patient's condition. In some cases, it may be necessary to take a picture at. In such a case, the left and right reversal processing of the image must be performed after the photographing. Thus, the instruction unit 207 can instruct the display image rotation inversion unit 204 to perform a left-right inversion process or a rotation process (rotation, inversion change). Upon receiving such a rotation / reversal change instruction, the display image rotation / reversal unit 204 rotates and reverses the image according to the instruction, and redisplays the image.

Next, when the operator finally understands the image arrangement, the arrangement calculation is determined. There are two ways to do this. One is that the operator explicitly specifies the instruction unit 207.
There is a case where an instruction is issued from the user and a case where a timeout occurs without an instruction from the operator. In the present embodiment, both are performed, and the timeout time is one minute.

When the arrangement calculation is finalized, the photographed image, the arrangement coordinate determination value, and the rotation inversion determination value are stored in the temporary storage unit 208.
It is stored in the non-volatile storage device 122 (hard disk in this embodiment). Here, the captured image is an A / D converter 1
07, the arrangement coordinate determined value is a relative position of the irradiation field area with respect to the film area,
The rotation inversion determination value is the rotation value and the inversion value of the image determined by the display image rotation inversion unit 204. Then, the photographed image, the arrangement coordinate determination value, and the like are read again and the processing is performed, and the processing is performed in the background.

The reason for performing the processing in the background is that the processing described above is performed in a relatively short time because processing is performed on reduced images and logical calculation is mainly performed. Is 2688x for image processing
This is because it takes time to process the entire captured image as large as 2688 pixels, and it is a problem that the user cannot proceed to the next capture while performing this process. That is, if processing is performed in the background, the operator can quickly shift to the next imaging cycle. Therefore, the processing after the cutout unit 209 described below is executed in the background.

The cutout unit 209 is provided in the nonvolatile storage device 1
The storage device 12
A cutout process is performed based on the arrangement coordinate determination value read out from Step 2. This is a process of trimming the captured image according to the arrangement coordinate determination value. As a result, from the captured image,
A partial image of the irradiation field area is extracted.

Next, the photographed image is subjected to appropriate image processing in the image processing section 210 and adjusted so as to have an optimum contrast when making a diagnosis. Thereafter, it is provided to the sensor position marking unit 211.

The sensor position marking unit 211 is used as a remedy in the case where the designated rotation or reversal designation value is wrong. For example, as a case in which a remedy is necessary, when an operator takes an image of a subject with a setting to be taken with a PA (from back to front), when deciding the actual direction of the patient, it is absolutely necessary according to the patient's medical condition. In the case where the photographing has to be performed at the AP (front to back) and such photographing has been performed, the operator forgets to instruct the display image rotation reversing unit 204 to perform the reversing process. It is possible. In this case, such an image and P
It becomes indistinguishable from the case of shooting normally with A. This is because the film can be observed from both sides.

FIG. 8 is a view for explaining sensor position marking by the sensor position marking section. As shown in FIG. 8, after the clipping process is performed by the clipping unit, the upper left position of the sensor is marked on the upper left of the image indicating the upper left portion of the sensor. Then, even if the rotation is reversed, it is possible to know how the image was captured. In addition, since the marking is performed after the cutting process, the marking does not disappear by the cutting process.

Further, even if the marking information on the upper left position of the sensor is not actually written in the image, it is added to the header of the image data.
It is also possible to add information indicating which side of the image is the upper left corner of the sensor. In this case, especially when the final image is sent to a printer or a viewer, it is necessary for these receivers to read and interpret this header information.

After the sensor position marking is performed as described above, the image data is input to the rotation reversing unit 212. The rotation inversion unit 212 rotates and inverts the image according to the rotation inversion determination value stored in the hard disk. The processed image data is stored in the reduced marking unit 213.
Is input to

As described with reference to FIG. 5, the reduction marking section 213 reduces the irradiation field area and stores it on a film.
When an image is formed with the size reduced to the life size or less, a marking is provided so that the image can be clearly understood. Therefore, the need for such reduced marking is limited to the case where the output medium is a printer or a laser imager.

In this reduction process, many laser imagers have a function of printing the image at a life size or less on the laser imager side without reducing the output image. In the present embodiment, since the image reduction processing depends on such a laser imager, no reduction processing is performed.

This will be described in detail. The pixel size of the sensor of this embodiment is 160 microns and 2048
The image when cut out to x2560 pixels is 80
When sending to a micron laser imager, it is sent instructing to complement and magnify the image by a factor of two. Then, the image is complemented and magnified twice by the laser imager and an image of 4096 × 5120 pixels is output. And that case is just life size.

However, if the operator explicitly selects the entire sensor area and prints it, 2688 × 268
It becomes 8. This is because, in an 80-micron printer having a buffer area of 4096 × 5120 in the horizontal and vertical directions, the enlargement ratio of the image is limited by the enlargement ratio in the horizontal direction. That is, 4096/2688 = 1.523, and the maximum enlargement ratio is obtained when the image is complementarily enlarged and printed about 1.523 times. Therefore, transfer is performed with an instruction of 1.523 times enlargement. This is an enlargement process in terms of data, but is smaller than the life size from the point of view of the operator, so it is a life size reduction process.
FIG. 9 is a diagram illustrating an example of the reduced marking. It is.
In FIG. 9, reference numeral 901 denotes a reduction marking, which clearly indicates that the image is reduced. Thereafter, the image is output to the outside by the output unit.

Next, the processing of the irradiation field area arrangement calculation unit 203 will be described. FIG. 10 is a flowchart showing the processing by the irradiation field region arrangement calculation unit.

First, in step S11, irradiation field area information indicating an irradiation field area of a captured image is
Enter from 1. Next, in step S12, the height and width of the recognized irradiation field area are compared. If the vertical direction is longer, the symbol A is vertical and the symbol B is horizontal (step S
13). If the horizontal side is longer, the reverse is true (step S14).

Next, in step S15, the variable I is initialized to 1. This variable I is used when checking a table in which a size designated in advance is recorded. Further, in the present embodiment, the table shown in FIG. 4 is used, but this can be registered in advance as an initial setting by the operator. That is, it is possible for the operator to register a desired designated size.

Next, in step S16, the layout classification is A in the table of FIG. 4 (for example, if the irradiation field area is vertically long, the layout classification is "vertical" in FIG. 4).
From the pixel having the smaller number of pixels in the A direction to I
Select the second size (thus, when processing this step for the first time, the first size is selected). However, at this time, if the number of pixels in the A direction is the same, the pixel is selected from the smaller one in the B direction. The table is arranged in ascending order of the indices when the indices are vertical and horizontal.
Also, when the arrangement classification is vertical, they are arranged in order of horizontal size when the arrangement classification is vertical, and are arranged in order of vertical size when the arrangement classification is horizontal (for example, when A is vertical) In the case where the arrangement classification is vertical), the search is performed in ascending order of the length.The smallest one is "quarter-cut vertically", while the second smallest one is "large-angle" and "half-cut vertically". Considering the number of pixels in the horizontal direction, the second smallest pixel is the “large angle”).

In step S17, it is determined whether the I-th size has been selected in step S16. Step S16 described above and steps S18 to S18 to be described below
In the process in S21, I is used until an appropriate size is obtained.
Are incremented one by one. If the I-th size no longer exists, it indicates that an appropriate size could not be obtained. Therefore, if it is determined in step S17 that the I-th designated size does not exist, the process proceeds to exception processing. For example, in the table of FIG. 4, since there is no fourth one from the smallest in the vertical arrangement, the processing shifts to the exception processing when I = 4. The exception processing is the exception processing described with reference to FIGS.
There are two ways.

On the other hand, if the I-th designated size is selected in step S16, the process proceeds from step S17 to step S18. In step S18, it is determined whether the irradiation field area input in step S11 falls within the selected designated size. If the irradiation field area is within the specified size,
Proceeding to step S22, the coordinates of the designated size are determined such that the center of the selected designated size is the center of the irradiation field recognition area (after obtaining the arrangement coordinates), and this processing ends.

On the other hand, if the irradiation field area does not fit within the designated size, the flow advances to step S19 to calculate the protruding margin. FIG. 11 is a diagram illustrating the margin calculation in the present embodiment. In general, in irradiation field recognition, irradiation field boundaries are ambiguous, and an area effective for diagnosis is relatively located at the center of an image. For this reason, even if the vicinity of the irradiation field region is slightly excluded, it is considered that an area effective for diagnosis is not excluded. Therefore, as shown in FIG.
If the vertical and horizontal protruding portions (margins) with respect to the film size (specified size) fall within predetermined ranges, the irradiation field area may be set to be equal to the horizontal or vertical size of the specified size. Judge. This is also applied to the case where the image protrudes only horizontally and the case where the image protrudes only vertically. In the present embodiment, in step S19, the size of the protruding portion is calculated,
In step S20, it is determined whether or not the size is within 5% of the length of the film in the protruding direction (the length of the film in the vertical direction if it is vertical, and the length of the film in the horizontal direction if it is horizontal). If it is within 5%, the process proceeds to step S23, in which the irradiation field area is narrowed from the irradiation field recognition calculation result so as to enter the designated size. Thereafter, the process proceeds to step S22, where the arrangement coordinates are determined.

In step S20, the size of the protruding margin is 5% of the film length in the protruding direction.
If it exceeds, the process proceeds to step S21, in which the variable I is incremented by one to check the next designated size, and then returns to step S16.

As described above, the irradiation field region calculation unit 203 selects an appropriate designated size for output based on the recognized irradiation field region, and selects the designated designation of the irradiation field region. Determine the placement position for the size.

FIG. 12 is a diagram for explaining a display method on the display unit 206. FIG. 12A shows a state in which reduced images of the irradiation field area frame 1001, the film frame 1002, and the sensor area (all image areas) 1003 are overlaid on the basis of the calculated arrangement and displayed. FIGS. 12B and 12C show the irradiation field region frame 100.
1. The reduced images of the sensor area 1003 and the output image area frame 1004 are displayed in an overlay manner. The output image region frame 1004 indicates the output image region determined in the irradiation field region arrangement calculation described with reference to FIG. In FIGS. 12B and 12C, the film frame is not shown. In the system according to the present embodiment, any one of (a), (b), and (c) can be selected as a display mode.

As described above, according to the present invention, an effective portion of an image is output in an appropriate size in a commercially available film having a predetermined size or a commercially available image viewer having a predetermined maximum receiving size. This makes it possible to form an image on an existing medium or viewer without losing information. As a result, there is no need for a custom film, printer, or custom image viewer, so that the economic effect for the user is great.

In the present embodiment, in order to make the implementation easier and to simplify the description, the realization by software has been described. However, in the case of higher-speed processing, the implementation is performed by hardware. This does not impair the purpose of the present invention.

Even if the present invention is applied to a system including a plurality of devices (for example, a host computer, an interface device, a reader, a printer, etc.), an apparatus (for example, a copying machine, a facsimile machine) comprising one device Device).

Another object of the present invention is to provide a storage medium storing a program code of software for realizing the functions of the above-described embodiments to a system or apparatus, and to provide a computer (or CPU) of the system or apparatus.
And MPU) read and execute the program code stored in the storage medium.

In this case, the program code itself read from the storage medium realizes the function of the above-described embodiment, and the storage medium storing the program code constitutes the present invention.

As a storage medium for supplying the program code, for example, a floppy disk, hard disk, optical disk, magneto-optical disk, CD-ROM, CD
-R, a magnetic tape, a nonvolatile memory card, a ROM, or the like can be used.

When the computer executes the readout program code, not only the functions of the above-described embodiment are realized, but also the OS (Operating System) running on the computer based on the instruction of the program code. ) May perform some or all of the actual processing, and the processing may realize the functions of the above-described embodiments.

Further, after the program code read from the storage medium is written into a memory provided in a function expansion board inserted into the computer or a function expansion unit connected to the computer, based on the instruction of the program code, It goes without saying that the CPU included in the function expansion board or the function expansion unit performs part or all of the actual processing, and the processing realizes the functions of the above-described embodiments.
