BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for facilitating confirmation and selection of a window being displayed in a multi-window display.

[0002]

2. Description of the Related Art FIG. 4 shows an example of a conventional multi-window display. FIG. 4 shows an example in which the number of windows is two (P1, P2).
The selection menu of the mark is attached. In the case where the screen (a) in the figure is the screen before the selection, when the mark m1 is selected, the entire window P1 becomes visible as shown in the figure (b). When the mark m2 is selected, FIG. In Figure 4, it looks like two windows, but actually it is P1 or P2.
There may be a third window P3 hidden underneath. This may be the case in a device having a function of moving the position of the window or a function of changing the window size. In such a case, the entire window being displayed cannot be grasped. Further, since the selection menus m1 and m2 are physically separated from each other, the selection operation is not quick.

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art to facilitate the selection of windows, and the window being displayed without hiding the selection menu even if the window is freely moved. It is an object of the present invention to provide a multi-window display device for the purpose of being able to grasp at a glance the number of

SUMMARY OF THE INVENTION According to the present invention, in an apparatus for displaying a window pattern consisting of a plurality of windows, image data for each window in which a frame of a different color is attached to each window and the color of the frame are provided. And a window pattern ROM that stores data relating to a selection menu composed of the same color mark array, and image data for each window transferred from the window pattern ROM and data relating to the selection menu. A display image memory that is stored for display
A multi-window having a CPU for controlling the window pattern ROM and a display image memory, and when selecting an arbitrary window from the window pattern, a mark having the same color as the window is selected from the selection menu. A display device is provided.

[0005]

[Function] Each window frame is given a different color. Then, marks having the same color as the window frame corresponding to each window are collected and displayed as a selection menu at a position separated from the windows. The image data of this window and the data of the selection menu are RO for the window pattern.
It is stored in M. Therefore, the window selected by the external operation and the mark of the same color as the frame color are CP
Under the control of U, it is read from the ROM, transferred to the display image memory, and displayed on the display.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A multi-window display device according to the present invention will be described below with reference to the drawings. 1 is a block diagram of an essential part showing an embodiment of a multi-window display device according to the present invention, FIG. 2 is a block diagram of an essential part showing another embodiment, and FIG. 3 is an example of a display image for explaining the present invention. FIG. In FIG. 1, 1 is an input unit for performing operations such as window selection, 2 is a CPU for controlling the window pattern ROM 3 and display image memory 4, and 3 is a window pattern for storing image data of windows and selection menu data. ROM, 4 is a window pattern R
The display image memory 5 for storing the image data transferred from the OM 3 and displaying it on the display is an interface for coping with external input. Further, in FIG. 2, 6 is an input unit for selecting a window and changing the color and size of the window frame, 7 is a CPU, 8 is a window pattern ROM for storing image data of each window, and 9 is Window pattern system RAM for storing window parameters (window frame and selection menu color, window frame size), image data and selection menu data according to the parameters, and 10 for storing the window pattern system RAM RAM
It is a display image memory for storing the image data transferred from the device and displaying it on the display.

Next, the operation of the present invention will be described. First, FIG. 1 will be described. L1 in the figure is the control signal line,
L2 is a data line. ROM for window pattern
3 stores image data of each window and selection menu data. FIG. 3A shows a display example before the window is selected. As shown, there are three windows P1, P2, and P3, of which P3 is below (behind) P1 and hidden. Then, different colors are given to the frames (S1, S2, S3) of each window. Also, the selection menus (m1, m2, m3) corresponding to the three windows are displayed at positions separate from the windows as illustrated. Then, the same color as the frame of the corresponding window is given to each of m1, m2, and m3 that compose the selection menu. In this example, S1 corresponds to m1, S2 corresponds to m2, and S3 corresponds to m3.

Here, if a desired item (for example, m2) is selected from the selection menu (m1, m2, m3) by the input unit 1, a window (P2) having a frame of the same color as that color is selected. [FIG. 3 (b)]. Similarly, if P3 hidden under P1 is desired to be displayed, selecting m3 will display it as shown in FIG. Specifically, based on the signal from the input unit 1, the CPU 2 uses the L1 line to perform the window pattern RO.
The stored data is read from M3, and the data is transferred to the display image memory 4 by the L2 line and stored. The display image memory 4 outputs the stored data so that it can be displayed on a display monitor.

The present invention can be applied to window display of external input (claim 2). In this case, the external input captures the image via the interface (I / F) 5,
A frame with one color and a selection menu are assigned to the captured image. This allocation is controlled by the CPU 2. Thereby, when the mark of the assigned color is selected from the selection menu, the external input window is selected. Next, FIG. 2 will be described. In the case of FIG. 1, the window pattern and the selection menu data are fixed. On the other hand, in the case of FIG. 2, the color of the window frame and the selection menu is changed, or the size of the window is changed. For this purpose, a window pattern system RAM 9 is provided. The parameters of the window being displayed (the color of the window frame and the selection menu, the size of the window frame) are written in the system RAM 9 by the CPU 7 when the window is read. Then, when the parameters are changed by the input unit 6, they are rewritten at any time. Since the CPU 7 manages all the parameters of each window, the colors of the window frame and the selection menu do not overlap.

[0010]

As described above, according to the present invention, in the multi-window display, the selection menu in which the frame of each multi-window is provided with a dedicated color and the marks of the same color are arranged is provided in the window. Since it is provided at a position different from that of the above, when selecting a window, the window can be selected by designating a mark of the same color as the frame from the selection menu. This makes it easy to select a window, the selection menu is not hidden even if the window is moved freely, and the number of windows being displayed can be easily confirmed. It contributes to the function improvement.
