Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an image display device capable of simultaneously displaying $J images on a display section.

(Prior Art) Conventionally, in an image display device equipped with a multi-window function, a plurality of images can be displayed simultaneously on a display unit.

For example, when performing comparative observation of each displayed image in such an image display device, there is a demand for observing an arbitrary part of each image by moving it to a predetermined position on the display section where it can be easily compared and observed. Conventionally, this request has been responded to as follows.

That is, for example, when two images 17a and 17b are displayed simultaneously on the display unit 17 as shown in FIGS. 4(a) and 4(b), the display position of each image 17a and 17b can be moved as follows. I'm like.

First, by operating the joystick 15 for inputting the movement information of the image 17a, the image 17a is moved to a predetermined position indicated by 17a', and then by operating the joystick 16 for inputting the movement information for the image 17b. Similarly, the image 17b is moved to a predetermined position 17b', and by performing such a moving operation for each image, the display images are moved to predetermined positions 17a' and 17b', respectively.

Therefore, even if it is desired to simultaneously move each displayed image, there is no other way to move the images than to repeat the above operations.

(Problems to be Solved by the Invention) However, in such an operation method, when a plurality of images are displayed, it is required to repeatedly and redundantly perform the same operation on each image. Roughly,
Since each image must be operated individually, there is a problem in that it is difficult to move each image in exactly the same way.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an image display device that can simultaneously move a plurality of images displayed on a display section.

[Structure of the Invention] (Means for Solving the Problem) The structure of the present invention for achieving the above object is an image display capable of simultaneously displaying a plurality of images on the same display section or on a plurality of display sections. In the apparatus, a movement information input means for inputting the movement direction and movement amount of the image displayed on the display unit;
The apparatus further includes a movement control means for simultaneously controlling the movement of each image on the display section according to the input movement information.

Further, the movement control means may control the movement of each image simultaneously or individually according to input movement information.

(Function) The function of the present invention having the above configuration is that each image displayed on the display section is simultaneously moved in an arbitrary direction by inputting movement information of the image from the movement information input means. There is.

(Example) The present invention will be explained below with reference to the drawings.

FIG. 1 is a block diagram schematically showing an embodiment of an image display device.

In the figure, the image display device includes an image memory 2 that stores a plurality of image data, a display memory 4 that temporarily stores an image to be displayed among the stored images, and a display memory 4 that temporarily stores an image to be displayed among the stored images. a display section 7 made of, for example, a CRT, which displays images that have been stored, a keyboard 8 which inputs various other information such as incidental information about the displayed image, and movement information of the image displayed on the display section 7. movement information input means 11 for manually inputting information, and C serving as the center of control for the entire device
The control unit 1 includes a PU and the like. Note that 3 in the figure is an interface for connecting the keyboard 8.

The movement information input means 11 includes an external input section 6 equipped with joysticks 6a to 6C for instructing the moving direction of the image displayed on the display section 7 and the movement m in that direction, and input from the external input section 6. The controller 5 inputs the output, converts it into movement information of each image displayed on the display section 7, and outputs it to the control section 1.

In this embodiment C, among the joysticks 6a to 6C, the joystick 6a and the joystick 6C are configured to input the movement direction and movement amount of each image displayed on the display unit 7, and the remaining joystick 6b The direction and amount of movement for simultaneously moving each image displayed on the display section 7 is input. Further, the amount of movement is manually controlled in accordance with the operation time of each joystick, that is, the time of tilting in the desired direction.

Roughly speaking, when a plurality of images consisting of three or more are displayed on the display unit 7, the correspondence between each displayed image and the joystick is such that each displayed image is displayed in a certain order with respect to the joystick 6a or joystick 6C. It may also be possible to switch by corresponding to

Incidentally, in this embodiment, a joystick is used to input image movement information, but the present invention is not limited to this. For example, various input means such as a trackball, a normal keyboard cursor movement key, or a mouse can be used instead of the joystick. Of course, it can be used.

In addition to controlling the entire device described above, the control unit 1 also controls the movement information outputted from the movement information input means 11.
It functions as a movement control means that simultaneously controls the movement of each image on the display unit 7 according to the input movement information, and also controls the movement of each image simultaneously or individually according to the input movement information. It also has the ability to function as a control means.

Further, the functions of these movement control means are realized based on a program, which is not shown in the flowchart shown in 1', which will be described later.

The operation of the present apparatus having the above-described configuration will be explained with reference to the flowchart shown in FIG.

First, in step 1, the joysticks 6a to 6 are
It is determined whether any of the joysticks C has been operated. Here, if none of the joysticks is operated, the input standby state is maintained until any one of the joysticks is operated. On the other hand, if any joystick is operated here, the process proceeds to step 2.

In step 2, it is determined whether the joystick 6a is used or not. Here, if the operated joystick is 6a, the process proceeds to step 6, and if it is another joystick, the process proceeds to step 3.

In step 6, the read address of the display image corresponding to the joystick 6a from the image memory 2 is converted by the movement RΔX corresponding to the tilt direction, that is, the movement direction of the joystick 6a and the operation time thereof. Then, proceed to step 7.

On the other hand, in step 3, it is determined whether the joystick is 6G or not. Here, if the operated joystick is joystick 6C, the process proceeds to step 5; otherwise, since the operated joystick is 6b, the process proceeds to step 4.

In step 5, the read address of the display image corresponding to the joystick 6C from the image memory 2 is converted based on the moving direction and the moving amount ΔX of the joystick 6C. Then, proceed to step 7.

On the other hand, in step 4, the read addresses from the image memory 2 of the display image corresponding to the joystick 6b, that is, all the displayed images, are converted according to the movement direction of the joystick 6b and the movement port ΔX.

Then, proceed to step 7.

In step 7, the corresponding image data is transferred from the image memory 2 to the display memory 4 based on the read address converted as described above. Then, proceed to step 8.

In step 8, the image data in the display memory 4 is displayed on the display section 7.

In this way, the displayed image is moved to an arbitrary predetermined position.

Next, the operation of the apparatus described above will be explained with reference to FIG.

First, images 7a and 7b are displayed on the display section 7.

In this case, the joystick 6a inputs the movement direction and movement amount of the image 7a, and the joystick 6C inputs the movement direction and movement amount of the image 7b.
The direction and amount of movement are entered, and
The joystick 6b is used to simultaneously input the moving direction and moving mouth of both images 7a and 7b.

By the way, both images displayed on the display unit 7 are shown in FIG.
As shown in , if the same image is an image of the subject's stomach, for example, in this embodiment, both images 7a and 7b can be displayed simultaneously on the display unit 7 by simply operating the joystick 6b up, down, left, and right. It can be moved arbitrarily with just 51 operations. In addition, if the two images are different images or images with different scales, please use the joystick 6a in advance.
.

Operate 6C to move the part to be comparatively observed to a predetermined position on the display section 7 (), then move it to any display position at the same time by simply operating the joystick 6b in the same way as above. You will be able to do so.

Note that 7a' and 7b' in the figure do not show a state in which the images 7a and 7b are simultaneously moved to the right in the figure.

With the image display device having the configuration described in detail above, a plurality of display images can be moved simultaneously in one operation, and the operation can be made extremely easy.

It should be noted that the present invention is not limited to the illustrated embodiments described above, and various modifications can be made within the scope of the invention.

For example, in the embodiments described above, multiple images can be displayed on the same display section and these images can be moved simultaneously or individually. One image may be displayed on the display and each of these images may be moved simultaneously or individually.
