DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides input image data in 10. The image display 1i has an image data buffer for storing and a display means for displaying a conversation screen and a reference image along with the main image. 1
do.

(Prior Art) In devices that diagnose using images, such as medical tomographic m-image devices, cathode ray tube display S! (hereinafter referred to as CRT)
Diagnosis is performed by storing the displayed image on film as a still image and observing the film image later. For example, when an X-ray tomographic image is displayed as the main image, the X-ray detector pAfII is displayed superimposed on the main image in order to obtain reference information such as knowing the position of the tomographic image on the subject. , conversations from various diagnostic programs were displayed as essential information over the main image, but this had the disadvantage that part of the main image of the liver buttock was obscured. In order to avoid this, the width or height of the screen is expanded to display conversation screens and reference images so that they do not overlap with the main image. An example of such image display is shown in FIG.

In the figure, 1 is a display screen that displays images obtained by the diagnostic device. 2 is a main image displaying a tomographic image, etc., a conversation screen 3 is displayed on the right side, and a reference image 4 is displayed superimposed on the conversation screen 3 at the bottom. 5 is a grayscale bar that displays the gray level of the image.

(Problems to be solved by the invention) When taking an image as shown in Fig. 5 with an imager,
If the imaging range of the imager is the same as the size of the main image 2 as in the conventional case, the conversation screen 3 and the reference image 4 cannot be shaded. Also, if the imaging range of the imager is made the same as the size of the display screen 1, the size of the main image 2 will become smaller,
There is a drawback that the award is withdrawn even when the reference image 4 is not displayed or when it is not desired to photograph the conversation screen 3 or the reference image 4.

The present invention has been made in view of the point L, and its purpose is to move reference images and conversation screens to arbitrary positions on the main image as necessary in order to enlarge the range photographed by the imager. An object of the present invention is to realize an image display device capable of displaying a main image in the maximum size without obstructing the focused part of the main image.

(Means for Solving the Problems) The present invention that solves the above problems includes an image data buffer that temporarily stores input image data, and a display that displays a conversation screen and a reference image together with the main image. an input means for inputting information such as on/off information of mapping between a conversation screen and a reference image, mapping type and display position trade information, and a main storage means for storing the information from the input means; , a frame management storage means classified into frames into which information regarding the main image, conversation screen, reference image, and mapping are inputted, and controls for writing information from the input means into the main storage means and the frame management storage means. The present invention is characterized by comprising a central control means and a frame control means for displaying at a specified position on the display means based on information from the frame management storage means.

(Operation) The mapping mode and mapping position are input into the main storage means by operating the input means according to the mapping setting sequence, and the conversation screen, the reference image, and the conversation screen and the reference image are mapped through the mapping on/off sequence.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of an embodiment of the present invention.

First, the screen displayed by the apparatus of this embodiment will be explained with reference to FIG. In the figure, the same parts as in FIG. 5 are given the same reference numerals. Reference numeral 11 denotes a first frame for displaying the main image, and the area photographed by the imager is only within the range of this first frame, making it possible to photograph an image of sufficient size. 12 is a second frame for displaying a conversation screen for conversation with the operator, and 13 is a third frame for displaying a reference image, which is displayed superimposed on the first frame 12 at the bottom of the second frame. There is. Reference numeral 14 denotes a fourth array which maps the conversation screen displayed in the second frame 12 into the film to be photographed at a desired time, and allows the fourth array to move freely within the first frame 11. be able to. A fifth frame 15 maps the reference image of the third frame 13 into the first frame 11, and can be moved within the first frame 11 in the same way as the fourth frame 14. In the figure, between the second frame 12 and the third frame 13, the first frame 11, the fourth frame 14. During the fifth frame 15, the frame is ff! If so, the one with the highest number will be displayed with priority. Therefore, for example, if the fourth frame 14 is displayed on the first frame 11 and the fifth frame 15 overlaps a part of the fourth frame 14 as shown in FIG. 2, the fourth frame 14 and the fifth frame 1st of 15 parts
The image in frame 11 is not displayed, and the image in frame 1
In the portion where the fifth frame 15 of No. 4 overlaps, only the reference image is displayed.

Next, the apparatus of the embodiment will be explained with reference to FIG. In the figure, 21 has five sections inside it, and the first to fifth frames shown in FIG. The location is written in the fourth frame.

Each of the fifth frames is a frame management storage section that stores information regarding the conversation screen and reference images, as well as the address of the position on the screen where the mapping is to be displayed, the size of the mapping, and the like. For example, in the fourth frame 14, if the frame is on and the image is off, only the frame remains, and neither the main image nor the conversation screen is displayed within the frame. Reference numeral 22 denotes an input device for inputting information such as image on/off and frame on/off for each frame using a keyboard, and inputting the position of the mapping on the screen, the size of the mapping, etc. using a trackball. Sent to 23. The input device 23 also has a 'Set△rea Move' button and an 'AreaMove' button, and a 'Set Area Move' button.
a Move ``The button is a normal push button switch.'' A,
The "rea Move" button is an alternate type switch whose contacts change each time it is pressed. 24 stores each piece of information sent from the central control unit 23, and the content is sent to the central control based on a request from the input device 22. This is a main storage section that stores data into the frame rate management storage section 21 via the section 23.

2-5 is an image data buffer that temporarily stores the scan data sent via the main memory 324, and the route of this data is omitted. The addresses of the main image data, conversation screen data, and reference image data written in the image data buffer 25 are written in each frame of the frame management storage section 21 as the location of the image data. Reference numeral 26 denotes a frame control section that synthesizes each frame based on information regarding each frame written in the frame management storage section 21 and causes the display 27 to display the synthesized frame.

Next, the operation of the sequence of "mapping setting, mapping on/off" in the above embodiment will be explained with reference to FIGS. 3 and 4.

When the "SOt Area Move" button on the input device 22 is pressed, the mapping setting program in the central control unit 23 is activated and performs operations as shown in the flowchart of FIG.

Step a: A prompt regarding the configuration mode appears on the display screen in conversational form.

step b The setting mode is entered numerically using the input device 22.

For example, 1; Conversation screen 2: Reference image 3; Conversation screen and reference image Step C A rectangular box-shaped cursor indicating the frame area selected based on the mode information input in step b is placed on the main image 2 of the first frame. will be displayed. For example, in the case of mapping a conversation screen, a box-shaped cursor appears on the display screen 1 in the size of the conversation screen previously stored in the main storage section 24.

Step d: Move the box-shaped cursor to the desired position using the trackball attached to the input device 22.

Step e: After completing the above settings, Re-turn the input device 22.
”Press the key to confirm.

Step f: When a confirmation input is entered in step e, information regarding the set mode and display position is written to the main storage unit 24, and conditions regarding mapping are set.

This completes the condition setting sequence for the mapped image. After the conditions are set in this way, "' A r
When the "ea move" button is pressed, the mapping on/off program in the central control unit 23 is started, and the operation shown in the flowchart in FIG. Area 1ylove
``When you press the button, select one of the conditions. Let's say it turns off first.

Step a: Check whether it is on, confirm that it is off, and proceed to step b.

Step b The fourth frame in the frame management storage section 21. Off information is set in the fifth frame. Therefore, no mapping is performed. , If mapping is not necessary, the first frame of only the main image is photographed in this state. If you need a mapping, use "' A re
Press the "a Move" button again to select the on condition.

Step a Make sure it is on. Since it is on, proceed to step C.

Step C: The designated mode is stored in the main storage unit 24, and the mode set in the mapping setting sequence described above is read.

Step d In this step when the mode specifies the third frame, there is an image in the third frame, but the frame management storage unit

In case 11, that is, when there is no image data in the third frame,
This is a mode setting error, so mapping does not occur.En1
leading to dopa.

Step e In the case of "'Yes", data related to the third frame in the frame management storage section 21 is transferred from the main storage section 24 to the fifth frame in the frame management storage section 21 and written therein.

Step f This is a step when the mode specifies the second frame, and since the conversation screen of the second frame always exists, data related to the conversation screen is transferred from the main storage unit 24 to the frame management storage unit 2.
It is transferred and written to the fourth frame within 1.

Step 9 The mode is set to 111 to capture the second and third frames at the same time.
mode. Similarly to step f, data regarding the conversation screen is transferred from the main memory 24 to the frame management memory 21.
The data is transferred to the fourth frame in the frame and edited.

Step h Similar to step d, if "No", proceed to "End" immediately after the step.

In the case of step i “Yes”, data regarding the reference image is transferred from the main storage unit 24 and written to the fifth frame in the frame management storage unit 21.

When the data of the conversation screen or the reference image is written into the fourth frame or the fifth frame, respectively, by the above sequence, the fourth frame 14 or the fifth frame 1 in FIG.
The conversation screen or reference image will be mapped at position 5. To change the mapping position and mapping mode, use “Set”
This can be easily carried out by pressing the "Area Move" button to perform the mapping setting sequence operation.

Note that there is a separate sequence for writing the image on/off information 9 and the location of the image data in the second and third frames, but this sequence is omitted because it is not part of the scope of the present invention.

As explained above, according to the present embodiment, mapping conditions are first set in the image setting sequence, and selection of whether or not to perform mapping is performed in the mapping on/off sequence. You can now set the mode and choose whether to perform mapping. Therefore, since the photographing range of the imager can be made the same as the image size, the main image on the film does not become smaller, and the conversation screen and the reference image 1 can also be photographed at the same time. Furthermore, since the display position can be set arbitrarily, the area of interest in the main image will not become invisible. Moreover, since there are three modes to choose from: reference image, gold-filled screen, and reference image and conversation screen combination mode, you can take pictures that suit your purpose.

Note that the present invention is not limited to the above embodiments. For example, the trackball attached to the input device may be a joystick, and the setting mode input is not numerical.
Input in other formats is also acceptable.

(Effects of the Invention) As described above in detail, according to the present invention, the conversation screen and the reference image are mapped onto the main image, the display position can be freely moved, and the display screen can be changed using the imager. When shooting, the conversation screen and reference image can now be displayed on top of the main image without interfering with the main image, and the imager's shooting range can now be displayed only within the main image.
The main image can now be displayed at its maximum size, which has a great practical effect.
