Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, when there are a plurality of images to be displayed and observed in an image workstation or the like, selects these images in order or randomly, and particularly displays the image once displayed and the image still displayed. The present invention relates to an image display method suitable for selecting and displaying a desired image while going back and forth between non-existing images.

[0002]

2. Description of the Related Art Conventionally, the following method has been used as an image display method adopted when there are a plurality of images to be displayed or observed in an image workstation or the like. That is, first, a plurality of images to be displayed are selected and displayed collectively on one screen of the image display device. In this case, a plurality of windows displaying images are sequentially displayed while shifting their positions little by little. The operator moves the window of the image that he or she wants to see most to a position on the screen where it is easy to see, displays the image by using a mouse or the like, and observes it.

[0003]

In the conventional image display method as described above, windows for displaying a plurality of images are overlapped with each other, so that one window other than the image of the window in the foreground is displayed. The entire image could not be observed. Therefore, move the desired window to a position on the screen where it is easy to see, as described above, and
Alternatively, after once converting it into an icon (pictogram) and selecting the icon with a mouse or the like, the entire image is displayed and observed, but such an operation is troublesome. Also,
The multiple display in which the windows were shifted little by little made the whole screen hard to see due to the crowded screen. These problems occur especially when the number of windows (images) displayed in one screen increases, and when the images are randomly selected from the foreground windows and displayed in random order, the images are displayed once. The more frequently the user selects and displays a desired image while going back and forth between the displayed image and the image that has not been displayed yet, the more remarkable it becomes.

An object of the present invention is to display and observe the whole image of a desired image one by one in a simple operation and in an easy-to-see screen display environment even when there are a plurality of images to be displayed and observed. In particular, when the images are randomly selected and displayed instead of the default order, the desired image can be switched back and forth between the image once displayed and the image not yet displayed. An object of the present invention is to provide an image display method capable of exerting a remarkable effect as the frequency of selecting and displaying is increased.

[0005]

When there are a plurality of images to be displayed and observed, those images are arranged in order,
Alternatively, in the image display method of randomly selecting and displaying, the image selection window data is written to the display memory for writing the image information to be displayed on the image display device, and the image selection window is displayed at a specific position. When the display of one image data is selected through the image selection window when the image data is not written in the display memory, the image data is written in the display memory to display an image, When display of other image data is selected through the image selection window while image data is being written in the display memory, the reference memory is prepared separately from the display memory. The image data written in the display memory is transferred and the transferred image data is converted to an icon. When the icon data that can specify is written in the display memory and then the other image data is written in the display memory to display an image, and the display of the iconized image data is selected via the icon. After transferring the image data written in the display memory to the reference memory and writing the icon data capable of specifying the image data in the display memory to iconify the transferred image data. This is achieved by writing the iconified image data in the display memory and displaying the image.

In the above-described method of the present invention, the images displayed on the image display device are 1 image, 1 image selection window, and 0.
Alternatively, there are one or more icons, and image selection can be performed only by looking at the image selection window and the icon. As a result, even when there are a plurality of images to be displayed and observed, it is possible to display and observe the entire image of a desired image one by one with a simple operation and in an easy-to-see screen display environment.
