Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an X-ray tube of an X-ray imaging apparatus having a function of performing imaging on an X-ray film and performing the imaging and X-ray fluoroscopy. The present invention relates to an X-ray control device that controls a high-voltage generator that supplies a tube current, the X-ray tube, and the like in accordance with a designated imaging control condition, and particularly relates to an imaging control condition for an imaging instruction item designated by an inspection request slip. The present invention relates to an X-ray controller configured so that designation can be performed easily.

[0002]

2. Description of the Related Art In a hospital or the like, a examinee requests each examination room to carry out an examination which the doctor deems necessary after receiving a doctor's examination in each department. X-ray imaging is one of them, and a doctor issues an examination request slip in which necessary imaging instruction items (imaging site, imaging method, etc.) are written.

In an examination room (such as a radiology department) for performing X-ray imaging, one or more (usually a plurality of) X-ray imaging devices and an X-ray tube provided in each X-ray imaging device are connected. X-ray high voltage equipment is installed. The X-ray high-voltage device controls the X-ray tube by supplying the X-ray tube voltage and the X-ray tube current to each X-ray tube, and controlling the high-voltage generator and each X-ray tube according to the designated imaging control conditions. It is provided with an X-ray control device and the like for performing radiography.

When the inspection request form issued by the doctor is delivered to the technician such as a radiology department, the technician operates the X-ray controller based on the contents written in the inspection request form, Set the X-ray control conditions that allow the specified X-ray photography to be performed.
Specified as a line controller.

Now, a method of designating the imaging control conditions will be described with reference to FIG. 10 showing an operation panel surface for designating the imaging control conditions in the conventional X-ray controller.

First, the technician selects an X-ray imaging apparatus for performing X-ray imaging of the imaging instruction item instructed by the examination request note, using the technique selection key. Which X-ray imaging device is used is one of the imaging control conditions. Next, the preset selection keys are used to select the shooting conditions such as X-ray tube voltage, X-ray tube current, shooting time, and shooting method. The imaging control conditions specified by this imaging condition and the selection of the X-ray imaging apparatus are set.

In the X-ray control device, for each technique selection key (each X-ray imaging device), there are as many imaging conditions as there are preset selection keys (in the X-ray control device having the operation panel shown in the figure, The number of technique selection keys (6) * the number of preset selection keys (6) = 36 imaging conditions) is stored in advance. Therefore, in the X-ray controller, when the operation method selection key is instructed, the imaging condition group corresponding to the operation method selection key (X-ray imaging apparatus) is read out, and then the preset selection key is instructed. The shooting condition corresponding to the preset selection key designated from the previously read shooting condition group is read.

Then, the X-ray controller controls the high-voltage generator, the X-ray tube and the like according to the imaging control conditions designated as described above to execute the X-ray imaging instructed by the inspection request slip.

[0009]

However, the prior art having such a structure has the following problems. That is, the imaging instruction items instructed by the examination request slip issued by the doctor are usually the imaging region (head, chest,
It is a combination of such things as knees) and shooting methods (simple shooting, tomography on film, etc.). Therefore, the technician replaces the imaging region and imaging method instructed in the inspection request slip, selects which X-ray imaging device to use with the operative method selection key, and the X-ray imaging according to the imaging region and imaging method. The shooting condition for performing the shooting has to be selected with the preset selection key, and there is a problem that it is difficult for an unskilled technician to specify the shooting control condition.

Further, what kind of photographing condition is set in each preset selection key of each X-ray photographing apparatus is as follows.
The X-ray control device installed in each examination room of each hospital differs. Therefore, an engineer unfamiliar with the operation of a predetermined X-ray control device does not know the contents of the imaging conditions for each preset selection key for each X-ray imaging device set in the X-ray control device. In order to make the selection smoothly, the technician must be familiar with the operation of the X-ray controller. Inexperienced engineers
The preset selection keys are sequentially selected, and the shooting conditions set in the preset selection keys are displayed on the operation panel (see FIG. 10).
The operability is extremely poor because it is necessary to specify the shooting conditions while displaying them on the upper part of the shooting condition display area (see the above) to check the shooting conditions. Moreover, an unskilled technician has no judgment as to whether the imaging conditions for performing X-ray imaging according to the contents instructed by the inspection request form are the imaging conditions displayed in the imaging condition display portion. .

Further, the X-ray control apparatus can be preset with the imaging conditions only for the number of preset selection keys for each X-ray imaging apparatus (six in the apparatus of FIG. 10), and the number is limited. is there. Therefore, when X-ray imaging is performed in a certain X-ray imaging apparatus under the imaging conditions equal to or more than the number of preset selection keys, when designating an imaging condition not set in the X-ray controller, the technician is closest to the imaging condition. Select the shooting conditions with the preset selection keys, and then use the adjustment keys (“+” and “-” keys) at the bottom of the operation panel (see FIG. 10).
Therefore, the X-ray tube voltage and the X-ray tube current have to be changed, and the operability is extremely poor.

Further, the contents of the photographing instruction items which can be instructed in the examination request slip are usually different in each hospital. However, the operation panel of the above-mentioned conventional apparatus is common to each hospital, and in the end, each hospital had to specify the photographing control conditions according to the specifications of the apparatus. It has been desired that each hospital can specify the imaging control conditions with good operability for each hospital according to the actual conditions of each hospital. However, the above-mentioned conventional operation panel is composed of a 7-segment display unit such as an LED and a key input unit using sheet keys, and the operation panel having such a configuration is used to manufacture an operation panel as desired for each hospital. Is difficult, and even if possible, the cost is too high to realize.

Further, when the X-ray imaging apparatus is newly connected or the imaging conditions are added or changed afterwards, which technique selection key the newly connected X-ray imaging apparatus corresponds to, With the conventional X-ray control device, it is necessary to remember which preset selection key the added shooting conditions were set to, or the contents of the changed shooting conditions. It is difficult to flexibly deal with additions, changes, etc. of the contents of the shooting instruction items that can be instructed by the request slip.

The present invention has been made in view of the above circumstances, and enables anyone to specify the photographing control condition for the photographing instruction item designated by the inspection request slip by a simple operation. In addition, it is possible to specify the shooting control conditions for each hospital with good operability according to the actual situation of each hospital, and to add the posterior device configuration, shooting conditions, and the contents of shooting instruction items that can be specified in the inspection request slip. It is an object of the present invention to provide an X-ray control device capable of flexibly responding to changes and the like.

An example of the photographing instruction item selection screen displayed on the color liquid crystal display 12 is shown in FIG. This radiographing instruction item selection screen has the same format as the examination request slip used in the hospital in which the X-ray control apparatus 6 is installed.

[0041] This inspection request slip (photographing instruction item selection screen)
In the case of 1, a list of shooting instruction items including a combination of a shooting region and a shooting method is printed (displayed) in the middle of the paper (screen). In the inspection request slip, the doctor selects a desired imaging instruction item (for example, 001. head) from the above list and gives an instruction on the inspection request slip. On the other hand, on the shooting instruction item selection screen, as described later, the technician presses the touch panel 13 to give the same shooting instruction item as the shooting instruction item instructed in the inspection request slip.

“Tomo” in the imaging instruction item on the inspection request note (imaging instruction item selection screen) means tomography, and the imaging site with “Tomo” is X by tomography. The radiography is instructed, and the X-ray radiography by the simple radiography is instructed for the radiographic parts not marked with "Tomo". That is, when an imaging region with “TOMO” is designated, the tomographic imaging stand is used, and in the case of simple imaging, simple imaging is performed X
Which X-ray imaging apparatus 1 of the X-ray imaging apparatus 1 is to be used is predetermined for each hospital depending on the imaging region.

Next, selection of shooting instruction items by the technician using the touch panel 13 will be described. The touch panel 13 has a large number of touch sensors arranged in a grid on a transparent panel, and when a predetermined position on the touch panel 13 is pressed, the touch sensor at the pressed position is turned on.
The position of the touch sensor on the touch panel 13 is detected. This touch panel 13
It is mounted on the display surface of the color liquid crystal display 12.

Further, in the item position memory 28, as shown in FIG. 4, a touch sensor (indicated by vertical and horizontal dotted lines in the drawing) of a virtual frame surrounding each shooting instruction item displayed on the color liquid crystal display 12 is displayed. Position information (for example, x, y coordinates when the surface of the touch panel 13 is the xy plane) and the shooting instruction items are stored in association with each other. For example, (x _i , y _j ) (where i
= M to m + 22, j = n to n + 4), the shooting instruction item “bbb.BB” (for example, “02
8. Foot ”) is associated. Therefore, when the touch panel 13 on the shooting instruction item to be instructed is pressed with a finger or the like, the position information on the touch panel 13 of the touch sensor which is turned on is transferred to the CPU 23 via the touch panel input circuit 24.
Is input to If the CPU 23 searches the item position memory 28 and there is a shooting instruction item corresponding to the input position information, the CPU 23 executes the following process using the shooting instruction item.

That is, the CPU 23 controls the touch panel 1
The shooting control condition corresponding to the shooting instruction item designated in 3 is read from the shooting control condition storage memory 30 and stored in the read condition memory 31. Note that there is a one-to-one relationship between each shooting instruction item on the shooting instruction item selection screen and the shooting control condition stored in the shooting control condition storage memory 30.

Then, the CPU 23 controls the GDC 25 to display the display screen data stored in the photographing control condition display memory 29 and the photographing control conditions stored in the reading condition memory 31 (the photographing instruction designated by the touch panel 13). Based on the shooting control conditions corresponding to the items), a shooting control condition display screen as shown in FIG. 5 is displayed on the color liquid crystal display 12.

This screen is a screen for displaying the photographing control conditions corresponding to the photographing instruction items designated on the touch panel 13. In FIG. 5, an X-ray imaging stand is selected as the X-ray imaging apparatus 1, and the X-ray tube 3 of the X-ray imaging stand 1 is supplied with an X-ray tube voltage of “100 kV” and an X-ray tube current of “100 mA”. , Small focus shooting is selected, photo timer shooting is selected,
It indicates that the X-ray imaging is performed under the imaging control condition in which the density of the photo timer imaging is “0” (intermediate density). Note that the photo timer shooting is performed by the dose detection sensor 4
The X-ray imaging is terminated when the integrated value of the irradiation X-ray dose from is reaching the irradiation X-ray dose for imaging at the specified concentration, while the timer imaging is the X-ray imaging for the set imaging time. Do. Therefore, when the photo timer shooting is selected, it is not necessary to specify the shooting time. In FIG. 5, since the photo timer shooting is selected, the shooting time is not necessary, but the shooting time (100 ms) is displayed as a guide for the shooting time, and the actual X in this case is displayed.
The line shooting does not end at the shooting time.

Then, when instructed by the start switch 14, the CPU 23 inputs the detection data from the dose detection sensor 4 via the input / output unit 32 in accordance with the photographing control conditions stored in the read condition memory 31. The high-voltage generator 5, the switching device 7, and the X-ray tube 3 of the selected X-ray imaging apparatus 1 via the input / output unit 32.
By controlling (focus switching) and the like, the X-ray imaging instructed by the inspection request slip is executed. When the X-ray photographing is completed, the photographing instruction item selection screen is displayed on the color liquid crystal display 12 and the next X
Prepare for line photography.

As described above, according to this embodiment, the photographing control condition corresponding to the photographing instruction item can be designated only by selecting and instructing the same photographing instruction item as the photographing instruction item designated by the inspection request slip. , Anyone can easily specify the shooting control conditions.

In the photographing control condition display screen shown in FIG. 5, by pressing the touch panel at the "+" and "-" portions of the drawing, the X-ray of the photographing control conditions read from the photographing control condition storage memory 30 is displayed. It is possible to finely adjust the tube voltage, the X-ray tube current, the shooting time, and the density at the time of shooting with a photo timer. Therefore, the item position memory 28 stores the position information of each "+" and "-" part at the time of this screen, and when each "+" and "-" part is pressed, C
The PU 23 changes the corresponding shooting condition of the read condition memory 31. In addition, as for the density at the time of photo timer photographing, "0" is an intermediate density, "-" is a low density, and "+" is a high density.

Further, an item such as "cancel" is displayed on the photographing control condition display screen, and the touch panel 1 of the "cancel" part is displayed.
When 3 is pressed, the selected shooting control condition may be canceled and the screen may be returned to the shooting instruction item selection screen.

Further, the photographing control condition display screen is not limited to the format shown in FIG. 5, and may be a screen of any other format. It should be noted that this imaging control condition display screen is a screen that can be used in common in each hospital, so in this embodiment, the same fixed screen format is used in all hospitals. Display screen data for displaying screens of different formats may be created in the photographing control condition display memory 29.

Also, the same X depending on whether the patient is an adult or a child.
Even when the X-ray image of the same imaged portion is taken by the X-ray image pickup apparatus 1, if the image pickup conditions (X-ray tube voltage, X-ray tube current, etc.) are different, “adult” or “child” is displayed on the image-pickup instruction item selection screen It is possible to select whether or not, and two types of shooting control conditions according to each shooting instruction item are stored in the shooting control condition storage memory 30, one for adults and one for children,
The photographing control condition may be read according to the combination of the selection of "adult" or "child" and the selection of the photographing instruction item. Similarly, even when the imaging condition differs depending on the body type of the patient such as “obesity”, “standard”, or “slim”, it may be added to the selection condition. Of course, the photographing control condition may be designated according to a combination of selection of “adult” or “child”, selection of body type, and selection of photographing instruction item. In addition, if the shooting conditions differ depending on the age and sex, it may be added to the selection conditions in the same manner.

By the way, when the X-ray imaging is instructed by the inspection request slip, the imaging direction may be instructed. For example, an imaged region A (for example, the head) that can be imaged in two directions is instructed as imaged region A (left) and imaged region A (right), or an imaged region B that is imaged in three or more directions (for example, neck region) ), There is a case where an instruction is made such as imaging site B (3 directions), imaging site B (2 directions), imaging site B (1 direction). In such a case, a selection instruction item obtained by adding the shooting direction to the list of shooting instruction items on the shooting instruction item selection screen (for example, shooting region A (left), shooting region A (right), and shooting region B (3 Direction), a photographing region B (two directions), a photographing region B (one direction), and the like) so that the photographing instruction items including the photographing direction can be separately selected and instructed. When two or more imaging directions are designated, the designated imaging directions are predetermined depending on the hospital (for example, if the imaging site B (two directions) is designated, the imaging directions are left and right). In some cases, each imaging direction is individually instructed (for example, imaging region B (front, right), imaging region B (front, left), or the like). In the case of the former, it suffices to provide an item called imaging region B (two directions) in the list of imaging instruction items on the imaging instruction item selection screen,
In the latter case, shooting instruction items corresponding to combinations of shooting directions may be provided.

When two or more directions of photographing are designated, X-ray photographing from the first photographing direction is performed based on the instruction from the start switch 14, and then X-ray film replacement or X-ray photographing apparatus. After adjusting the shooting direction of 1 etc., 2 according to the instruction from the start switch 14.
The X-ray imaging is performed from the imaging direction of the number plane, and the imaging from each imaging direction is performed only once with the start switch 1.
It is usual that the instruction is not performed continuously in accordance with the instruction from 4, but is performed twice or more. Moreover, the imaging conditions (X-ray tube voltage, etc.) may differ depending on the imaging direction.
Therefore, for the imaging instruction items for performing X-ray imaging in two or more directions, the imaging conditions for each imaging direction are stored as a series of imaging control conditions in the imaging control condition storage memory 30 in association with the imaging instruction items. Then, when the shooting instruction item is selected and instructed, a series of shooting control conditions corresponding thereto is read out, and shooting conditions for each shooting direction are displayed in the shooting condition display portion SJ in the middle of the shooting control condition display screen as shown in FIG. Is displayed. Then, when the start switch 14 is first instructed, the X-ray imaging is performed according to the first imaging condition, and when the start switch 14 is subsequently instructed, the X-ray imaging is performed according to the second surface imaging condition. Works like. At this time, on the imaging control condition display screen, a series of X-ray imaging from each imaging direction can be interrupted to return to the imaging instruction item selection screen (for example, after the X-ray imaging from the first imaging direction is completed, 2 It is possible to return to the imaging instruction item selection screen without performing the X-ray imaging from the second imaging direction). Further, it may be configured such that the photographing condition to be controlled can be selected and instructed when the next instruction is given from the start switch 14 from the photographing condition displayed in the photographing condition display portion SJ of the photographing control condition display screen.

In the above embodiment, the image capturing instruction item selection screen has the same format as the inspection request note, but the image capturing instruction item selection screen includes at least a list of image capturing instruction items that can be instructed by the inspection request note. It does not have to be in the same format as the inspection request slip. For example, at some hospitals, the list of shooting instruction items is not printed on the inspection request slip, and only the shooting instruction items requested this time may be written on the inspection request slip and given to the technician. Even if it is, the list of shooting instruction items that can be (or may be) instructed in the inspection request slip is displayed on the shooting instruction item selection screen, and if the shooting instruction items can be selected and instructed, It is possible to specify the shooting control condition based on the instruction with good operability.

When the number of shooting instruction items is large and the shooting instruction item selection screen cannot be configured with one screen, the shooting instruction item selection screen is configured with two or more screens, and the "next screen",
Items such as the “previous screen” may be displayed on the shooting instruction item selection screen so that switching of the screen can be instructed by the touch panel 13.

By the way, the number and contents of the photographing instruction items which can be designated by the examination request slip, the contents of the photographing control conditions, etc. are different in each hospital. Therefore, the data stored in the item selection screen display memory 27, the item position memory 28, and the imaging control condition storage memory 30 are different for each hospital. In the second embodiment, which will be described later, each data stored in the item selection screen display memory 27, the item position memory 28, and the imaging control condition storage memory 30 is stored in the X-ray controller 6.
Although it is configured so that it can be created / changed by, the creation of data according to each hospital in the item selection screen display memory 27, the item position memory 28, and the imaging control condition storage memory 30 (RO
The writing of data to M or the like) can be performed by a personal computer (personal computer), a workstation, or the like regardless of the device configuration of the X-ray controller 6. Therefore, the manufacturer stores the item selection screen display memory 27 and the item position memory 2 that store data according to the hospital's request.
8. It is also possible to create the imaging control condition storage memory 30 by a personal computer or the like, attach the memories 27, 28, 30 to the X-ray control device 6 and deliver the device 6 to the hospital. Therefore, also in this embodiment, the imaging instruction item selection screen can be displayed as desired according to the actual situation of each hospital.

In the above embodiment, the selection instructing means is constituted by the touch panel 13, but the selection instructing means may be constituted by a pointing device such as a mouse, a joystick with a push button, a keyboard or the like. When a mouse is used, an item is selected and instructed by an arrow on the screen, so that the CPU 23 recognizes the instructed item as in the case of the touch panel 13. When using a joystick or keyboard with a push button, select the desired item by swinging the joystick or operating the cursor keys on the keyboard to displace the highlighted items, and then press the joystick push button or keyboard. The return key or the like may be pressed to indicate the selected item.

Further, although the display means is constituted by the color liquid crystal display 12 in the above embodiment, the display means may be constituted by a monitor television, a CRT, an EL (Electro.Luminesence) display unit or the like. Further, the display means only needs to be able to display at least each shooting instruction item so that the technician can identify it. Therefore, if such a display can be displayed in characters or graphics (pictures, diagrams, etc.), it is possible to display the characters or graphics. Any one is possible. Further, display means without a color display function may be used.

Next, the configuration of the second embodiment of the present invention is shown in FIG.
This will be described with reference to FIG. As described above, the apparatus of the second embodiment is characterized in that the X-ray controller 6 can create and change the imaging instruction item selection screen and the imaging control conditions.

That is, as shown in FIG. 7, in the second embodiment, in the device configuration of the first embodiment, the setting device input circuit 41, the mode selection switch 42, and the condition setting screen display memory 43 are the CPU bus lines. 22 and a setting device 44 such as a keyboard or a mouse is connected to the setting device input circuit 41.
It is detachably connected to the (microcomputer 11). Further, the program memory 21 separately stores a shooting instruction item selection screen and a program for creating / changing shooting control conditions, and the item position memory 28 stores selection items on a shooting control condition setting screen described later. Position information corresponding to the display position is separately stored. further,
As described above, the item selection screen display memory 27, the item position memory 28, and the shooting control condition storage memory 30 are the CPU.
It is composed of a rewritable EEPROM. The other structure is the same as that of the first embodiment, so the same reference numerals as those in FIG. 2 are given and the detailed description thereof is omitted.

The mode selection switch 42 is configured to switch, for example, a screen creation mode, a condition setting mode, a normal mode, etc., and the selected mode is the CPU 2
3, and the CPU 23 executes processing according to each mode.

The normal mode is a mode for specifying the photographing control conditions described in the first embodiment. In this mode, the setting device 44 does not create or change the photographing instruction item selection screen or the photographing control conditions. Since it is unnecessary, the setter 44 is removed from the microcomputer 11 (this X-ray controller 6). Since the details of the operation in the normal mode have been performed in the first embodiment, the description thereof will be omitted here.

The screen creation mode is a mode for creating (changing) the shooting instruction item selection screen, and the condition setting mode is a mode for creating (changing) shooting control conditions. When these modes are selected, the shooting instruction item selection screen and shooting control conditions are created (changed).

Connect to

The configuration of the characteristic part of the apparatus of the second embodiment will be described in detail below, together with the operations of the operator (for example, an engineer) in the screen creating mode and the condition setting mode.

First, the case where the screen creation mode is selected will be described. In this mode, the operator
To operate the shooting instruction item selection screen. At this time, the character information is set from the keyboard, and the ruled line is set by operating the cursor keys or mouse of the keyboard. When a special character such as a pictogram is used on the screen, the character pattern is registered in the Kanji memory 35. When coloring the screen, the coloring information is set from the setting device 44. The screen being created is displayed on the color liquid crystal display 12 in real time.

Information (signal) from the setting device 44 is given to the CPU 23 via the setting device input circuit 41. CPU2
3 controls the GDC 25 to create the image information being created in the video memory 34 in real time according to the setting from the setting device 44 and display it on the color liquid crystal display 12. If there are kanji or special characters on the display screen, they are read from the kanji memory 35. When the coloring information is set, the information is set in the color palette 26, and the screen displayed on the color liquid crystal display 12 is colored according to the coloring information.

As described above, for example, when the shooting instruction condition selection screen as shown in FIG. 3 is created, the operator instructs the setting device 44 to end the screen creation. As a result, the display screen data for displaying the created shooting instruction item selection screen is written in the item selection screen display memory 27. Then, position information of the touch panel 13 is created according to the display position of each selection instruction item on the created screen.

The position information is created based on the correspondence between the display position of each shooting instruction item on the created shooting instruction item selection screen and the position information on the touch panel 13, for example, as shown in FIG. BB ”is (x _i , y _j )
(However, data corresponding to position information of i = m to m + 22, j = n to n + 4) is set from the setter 44 for each selection instruction item, and the data is written to the item position memory 28 via the CPU 23. Alternatively, the position information may be created by the following method.

That is, for example, as shown in FIG. 8, by operating the setting device 44 (the cursor key of the keyboard or the mouse), each of the shooting instruction item selection screens displayed on the color liquid crystal display device 12 is displayed. A ruled line is drawn so that the selection instruction item is surrounded by a frame. The area 51 surrounded by this frame is an instruction area for each shooting instruction item in the normal mode (a selection instruction item in the area 51 is instructed by pressing anywhere in the area 51).

When the operator completes the creation of the frame, the operator terminates it with the setter 44. As a result, the CPU 23
Calculates position information of the touch panel 13 corresponding to the area 51 in each frame. The correspondence between the position of each display dot on the screen of the color liquid crystal display 12 and the position information of the touch panel 13 is determined when the touch panel 13 is attached to the color liquid crystal display 12. Therefore, if the touch panel 13 is attached to a predetermined position of the color liquid crystal display 12, the correspondence between the position of each display dot and the position information of the touch panel 13 is determined. Remember. When a frame is created on the screen of the color liquid crystal display 12, the display dots included in the area 51 within the frame are determined. Therefore, the position information of the touch panel 13 corresponding to the display dots included in the area 51 in each frame is obtained. As a result, each frame is numbered, and the area 5
The position information of the touch panel 13 corresponding to 1 is written in the item position memory 28. For example, in FIG. 4, “bb
b. In a frame surrounded by “BB” (for example, this frame is referred to as a frame number 1), the position information of the frame number 1 is (x _i ,
y _j ) (however, i = m to m + 22, j = n to n + 4)
Is stored in the item position memory 28. On the other hand, as will be described later, if the shooting control conditions are stored in the shooting control condition storage memory 30 so as to correspond to the respective frame numbers, somewhere in the area 51 within the frame surrounding the shooting instruction item to be selected and instructed. When is pressed, the frame number of the frame including the pressed part can be known from the storage data of the item position memory 28, and the shooting control condition corresponding to the frame number is read from the shooting control condition storage memory 30. If issued, the shooting control condition for the shooting instruction item designated on the touch panel 13 can be read.
As a result, the creation of the position information of the touch panel 13 according to the display position of each selection instruction item on the created screen is completed.

In the above configuration, the shooting instruction item selection screen and the position information to be stored in the item position memory 28 are created continuously in the screen creation mode. (For example, the screen creation mode and the position information creation mode) may be configured to be performed independently.

Next, the case where the condition creation mode is selected will be described. When this mode is selected, the photographing instruction item selection screen is displayed on the color liquid crystal display 12 based on the display screen data stored in the item selection screen display memory 27.
