Abstract

PURPOSE:To display an image without displaying clearly a desired image out of superimposed images, by providing a display means which superimposed and displays plural bits of information, and a display control means which moves and displays the image to a position where it is not superimposed on a designated bit of remarked picture information. CONSTITUTION:A display command is outputted and dislayed to an image operating processor 3 at step S3. Next, at step S4,an operating parameter is inputted from a keyboard 5. At step S5 to judge the input data, when the data is decided as the one for the display of a next window, a processing is returned to step S1 again, and the processing is completed when the data representing the completion of the processing is inputted. Meanwhile, when the window positioning on a display picture in an inner direction is selected by the keyboard 5 by the judgement of step S5, the processings following step S6 are executed. At step S7, an inputted new coordinate position is stored, and at step S8, the re-displaying of an inputted coordinate value is performed on an image operating processor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display control method, particularly to a display control method for displaying a plurality of image information in a superimposed manner at the same time.

[Prior Art] A typical example of this type of display control method is a multi-window processing method. In this multi-window, when displaying each image information, each display position is shifted and the sixth
The images are displayed in an overlapping manner as shown in Figure (a).

When the operator wants to view or process a window at the bottom (that is, toward the back of the display screen), the operator shrinks the window at the front as shown in FIG. 6(b). Make the window at the bottom (rear) visible on the display screen, or shift the window in front a little as shown in Figure 6(c) so that the window at the bottom is visible on the display screen. was.

[Problem to be solved by the invention] However, in the former case, not only does it have the disadvantage that it becomes difficult to tell what data is being displayed, but it also returns to its original size after processing. This is unsatisfactory because it requires reversal processing.

In the latter case, the size of the display screen is limited, so when the front window touches the edge, it may not be possible to shift the position any further, and you may not be able to see all the windows below. Yes, it was extremely inconvenient.

The present invention has been made in view of the above-mentioned prior art, and it is an object of the present invention to provide a display control method that makes it possible to clearly display a specified window without changing the size of the window.

[Means for solving the problem] In order to solve this problem, the present invention has the following configuration.

That is, a storage means for individually storing at least two pieces of image information, a display means for displaying the image information in a superimposed manner, and a designation means for specifying one of the displayed image information,
When the specified image information is located in the back direction with respect to the display screen, the image information located in front of the specified image information of interest is moved to a position that does not overlap with the image information of interest. and display control means for displaying.

[Operation] In the configuration of the present invention, when the respective pieces of image information stored in the storage means are superimposed and displayed on the display means, and when the superimposed image information located in the back direction is designated by the designation means, the designated The image information positioned in front of the image information of interest is moved and displayed by the display control means to a position where it does not overlap the image information of interest.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a display control device in this embodiment.

In the figure, numeral 1 is a main memory used for the state of each land and work for each process, and numerals 2a and 2b are window buffers in which image data for each window is stored. 3 is a screen operation processor, and each window buffer 2a.

This is for drawing figures, characters, etc. on 2b. Reference numeral 4 denotes a screen synthesis video control unit that detects the vertical relationship between windows, synthesizes the window buffers 2a and 2b, and displays the result on the CRT 7. A keyboard 5 is used by the operator to enter data for window operations and various processes. A main processor 6 controls the entire device, and operates according to a program stored in an internal memory 6a.

In this embodiment, in order to simplify the explanation, the explanation will be made using two window buffers 2a and 2b, but the number may be three or more. In short, you only need as many buffers as there are windows.

FIG. 2 is an example of a window buffer being synthesized and a window being displayed on the screen. In this embodiment, the number of windows is two, and the view boat displayed on the screen is shown by an inclined portion.

FIG. 3 shows an example of window movement using this embodiment.

Conventionally, the window could not be moved beyond the CRT 7, and the window could only be placed so that the entire portion of the window always existed on the CRT 7, as shown in FIG. 6(C). In this embodiment, there is a world coordinate system as shown in FIG. 4, and windows are allowed to exist at all coordinates. At this time, a certain area of the coordinate system is mapped to the display screen of the CRT 7, and windows that deviate from that area exist but are not displayed on the CRT 7. By controlling the windows in this way, if you want to see the lower side of an overlapping window, you can do so by simply changing the coordinates of the upper window to a position that does not overlap the window.

FIG. 5 is a flowchart of this embodiment. Hereinafter, the above-mentioned operation will be explained according to this flowchart.

First, in step S1, the parameters for each window generation, ie, the coordinates of the window and the size of its area, are input. Next, in step s2, allocation of each window buffer is determined (secured), and in step S3, a display command is output to the image operation processor 3 for display. Next, in step s4, operating parameters are input from the keyboard 5. If it is determined in step S5 that the input data is for displaying the next window, the process returns to step s1, and when data indicating the end of processing is input manually, the input data is processed. end.

Now, in the judgment in step S5, if a window located at the back of the display screen is selected using the keyboard 5 (assuming that this window is already displayed at this time), the processing from step S6 onwards is performed. become.

In step S6, the window number to be moved, in this case the new coordinate position of the window located in front, is input manually. Next, in step S7, the new manually entered coordinate values are stored, and in step S8, the inputted coordinate values are redisplayed on the screen operation processor (FIG. 3).

By doing this, the window displayed on the front side can be moved to a desired position, and the entire window on the back side can be displayed.

As described above, according to this embodiment, it is possible to reliably display the entire desired image among the overlapping images.

Note that the amount of fJiIJ when moving and displaying the window located on the front side depends on the size of the specified window, but the data indicating the size of these windows is stored in the window buffer memory or memory 6a. This is what has been done.

[Effects of the Invention] As explained above, according to the present invention, when a desired image is specified among overlapping images, it is possible to reliably display the entire image.
