SOLUTION: In an image processor 1, an application program transforms the coordinate data of the mouse cursor displayed on a monitor 16 into the coordinate data of the monitor 3 side in response to an event request issued by an operating system, and transfers the external bit map data to a video memory 19 according to the coordinate data. In such a case, the coordinate data of the mouse cursor displayed on the monitor 16 are transformed into the coordinate data of the monitor 3 side according to the coordinate transformation data relating the coordinates between the monitors 3, 16, and the image of the mouse cursor is displayed on the monitor 3 by the exclusive external bit map data of the monitor 3 according to the coordinate data.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device, for example, a display screen for displaying an image to be processed by applying it to an editing device for adding a title or the like to an image reproduced by a video tape recorder or the like. According to the correlation of the coordinates with the operation display screen and the display screen for the operation, the display target having the almost same shape as the display screen for the operation is displayed on the display screen for the processing object by the dedicated image data, thereby improving the visibility and the operation. By effectively avoiding the deterioration of sex, a mouse cursor or the like can be simply displayed on the image to be processed to improve usability.

[0002]

2. Description of the Related Art Conventionally, some editing apparatuses of this type are connected to a computer and a title or the like is created by the computer. Such an editing device has a monitor for displaying an image to be processed and a monitor for displaying an object for operation, etc., and operates the mouse or the like while checking the image to be processed to operate the mouse. By clicking a desired object on the screen, the required processing can be selected.

[0003]

By the way, in this type of editing apparatus, if a menu, a cursor and the like similar to the operation display screen can be displayed on the image to be processed, the usability is improved accordingly. It is considered possible.

In this case, a method is conceivable in which bitmap data such as an object and a cursor to be displayed on the operation display screen is directly transferred to the video memory and is superimposed and displayed on the image to be processed. However, a monitor that displays the video signal output from the video tape recorder, etc.
Since the scanning frequency, number of scanning lines, resolution, color development, etc. are different from those of a monitor that is normally connected to a computer, it becomes difficult to visually confirm the objects, cursors, etc. displayed on the image to be processed, and in the end visibility There is a problem of deterioration.

As a similar technique, a method of overlaying an image to be processed on the display screen side for operation by an overlay structure and arranging an object or the like on this image can be considered. However, in the case of this method, the image to be processed is confirmed on the display image side for operation, and in the end,
The image to be processed is displayed with a resolution, color development, etc. different from the actual one, and there is a problem that the visibility of the image on the process side deteriorates.

On the other hand, a dedicated GUI (Graphical Us
er Interface) can be considered. In this case, it is also possible to create bitmap data for a dedicated object, cursor, etc. for the image to be processed. However, this method has a problem that the configuration of the application program becomes complicated. Therefore, it takes time to develop the application program, and the processing procedure becomes complicated. Also, the objects displayed on the operation display screen,
Even if the processing content or the like for the operation is different between the cursor and the like and the dedicated object or the cursor, it cannot be completely prevented, and eventually the operability may be deteriorated.

Regarding the display screens for operation and processing, by connecting the display areas of the object and the cursor, a dedicated GUI common to these two display screens is provided.
However, in this case, it is not practical because a dedicated display system is required.

The present invention has been made in consideration of the above points, and it is possible to effectively avoid deterioration of visibility and operability, and to display an object having the same shape as the display screen for operation as a display screen for processing. The present invention intends to propose an image display device that can be easily displayed on the screen.

[0009]

In order to solve such a problem, in the present invention, the coordinate data of the display target displayed on the first monitor is converted into the coordinate data of the second monitor in accordance with the coordinate association. An image corresponding to the display target of the first monitor is displayed on the second monitor from the image data for the second monitor according to the converted coordinate data.

By converting the coordinate data of the display target displayed on the first monitor into the coordinate data of the second monitor according to the association of the coordinates, the coordinates of the mouse cursor set by the operating system can be simplified by the application program. Can be converted to the second monitor side. Also, regarding the display of the object whose position is designated by the application program, the corresponding coordinates on the second monitor side can be easily generated. As a result, if the image corresponding to the display target of the first monitor is displayed on the second monitor by the image data for the second monitor that is, for example, bitmap data, in the application program, simply at the corresponding position,
The corresponding image can be displayed only by expanding the corresponding image data. Therefore, the mouse cursor, the object for event occurrence, etc. can be displayed on the second monitor in association with the first monitor, and the deterioration of operability can be effectively avoided by that amount and the object etc. can be displayed easily. You can Also, by using the dedicated image data, it is possible to effectively avoid deterioration of visibility.

Is output to the monitor 3 from the image processing board 6. Furthermore, the computer 5 has a read-only memory (ROM) 7 when the power is turned on or the reset switch is operated.
And the hard disk drive (H) according to the startup procedure and startup conditions stored in the random access memory (RAM) 8.
The operating program stored in the DD) 10 is started by the central processing unit 9. Further, the computer 5 starts up an application program necessary for image processing on this operating program, and the central processing unit 9 controls the whole operation according to this application program. It should be noted that in this embodiment, depending on the operating program, WINDOWS NT or WINDOWS 95

In this specification, for simplification of description, the operation of the central processing unit 9 on the operating system is mainly performed by the operating system and the operation of the central processing unit 9 on the application program. Will be described using the application program as the main subject of operation.

The interface circuit (I / F) 11 is
When the keyboard 12 and the mouse 13 are operated, the operation result and the operation amount are output to the bus BUS at a predetermined timing. The video memory 14 receives bitmap data, which is image data, via the bus BUS, and stores this bitmap data. Digital-to-analog conversion circuit (D /
A) 15 performs digital-analog conversion processing on the bitmap data stored in the video memory 14 to generate a video signal, and outputs the video signal to the monitor 16. Thereby, in the computer 5, various objects required for operation, a mouse cursor, etc. are displayed on the monitor 16 to form a display screen for operation.

In forming the display screen of the monitor 16, the random access memory 8 holds coordinate data etc. defining a plurality of windows in a part of its area, and selects data relating to the plurality of windows as required. Output. The contents of the video memory 14 are updated by the operating system in accordance with the selected and output data. Therefore, in the computer 5,
A plurality of windows in which various objects are arranged are prepared in advance, and in a state where the plurality of windows are arranged on the display screen of the monitor 16 in an overlapping manner, the upper and lower relationships are switched and displayed.

In this embodiment, the application program first forms a top window when activated by the operating system. Next, this window creates an external GUI area outside management window as a child window, and the entire display screen of the monitor 16 is covered by this external GUI area outside management window. Further, this external GUI area outside management window generates an external GUI area management window as a child window. Furthermore, this external GUI area management window generates a plurality of operation objects as child windows. In this embodiment, windows other than the top window are transparently generated, and as a result, only the top window is displayed on the monitor 16. This state is shown in FIG.

The top window is created in the same manner as a standard window that is transparent to avoid unnatural behavior. That is, in this kind of multitasking operating system, a plurality of programs can be executed at the same time, and application programs can be switched in response to a user operation. When another application program is being executed, this application program can be activated by clicking the corresponding top window of this application program with the mouse. Although it is not impossible to set the top window as the management window described above, in the case of a transparent window, the user cannot recognize this window, and if this application program suddenly becomes active when the user clicks on it. Unnatural behavior cannot be avoided. As a result, windows other than the management window are made child windows of the top window so that these windows do not react to the mouse when this application program is not active.

The interface circuit (I / F) 17 is
The control command issued by the central processing unit 9 is received via the bus BUS, and this control command is output to the video tape recorder (VTR) 2, whereby the operation of the video tape recorder 2 is switched.

The image processing board 6 is directly connected to the bus BUS of the computer 5, and the interrupt control circuit 18 outputs the synchronizing signal SY output from the video tape recorder 2.
Interrupt the bus BUS at a predetermined cycle based on NC
Output RQ. The video memory 19 uses the interrupt I
The bitmap data output to the bus BUS in response to the RQ is stored, and thus the image data corresponding to the display on the monitor 16 is held.

Digital-analog conversion circuit (D / A) 2
0 sequentially digital-analog converts the image data stored in the video memory 19 at a timing synchronized with the synchronization signal SYNC to generate a video signal S2. Addition circuit 2
2 adds the video signal S2 output from the digital-analog conversion circuit 20 to the video signal S1 output from the video tape recorder 2 and outputs it to the monitor 3.

FIG. 4 is a schematic diagram showing the contents of the hard disk device 10. The central processing unit 9 controls the overall operation of the image processing apparatus 1 by executing the processing program stored in the hard disk device 10. That is, the central processing unit 9 issues a control command to the video tape recorder 2 via the interface circuit 17 to control the operation of the video tape recorder 2. Further, in response to the operation of the keyboard 12 and the mouse 13 detected via the interface circuit 11, the entire operation is switched, and a title or the like to be added to the video signal S1 is created. Further, according to the instruction of the operating system, the bitmap data held or created by the application program is transferred to the video memories 14 and 19, whereby the corresponding images are displayed on the monitors 3 and 16 to improve the usability of the image processing apparatus 1. improves.

Here, this processing program is based on an operating system (OS) of the image processing apparatus 1, an image processing application program operating on the operating system, and an edit list created and executed by the application program. Composed.

The application program executes various processes by using a transparent window provided by the operating system. What is a transparent window?
It is a simple rectangle object that does not always have a part such as a title bar that realizes a special function that draws the image in the background in its own rectangular area.

When the application program creates this window, it creates a plurality of images according to the state it can take and holds them. For example, if this image is a push button, you can reserve two empty bitmaps equal to the window size, and use brushes, pens (these are provided by the operating system) to represent the convex and concave visual effects, respectively. Drawing function). Alternatively, the application program previously stores the pit map data and directly copies this to the empty bitmap.

In this way, the application program creates simple objects such as static controls, push buttons, radio buttons, check boxes, etc., which consist of only one window object. An object including a plurality of functional objects such as a scroll bar, a list box, and a combo box is created by a parent object having a plurality of objects inside and managing mutual functional cooperation. The internal bitmap data is formed of bitmap data provided as a standard by such an operating system, and is expanded in the video memory 14 to form a display screen of the monitor 16.

When a mouse operation or a keyboard operation occurs, the operating system sends a message identifying the event to the application program in response to these operations. This message is the window handle (identifier) by which the message should be processed.
And the accompanying information (mouse coordinates, key code, etc.) according to the type of the message. The application program further transfers this message to the corresponding window according to the window handle, and calls the processing routine associated with the window when the window is created. This processing routine identifies a message, allocates a process to each event such as a mouse button being pressed, released, moved, a keyboard pressed, released, etc., and performs an actual process. In this embodiment, the event handler is composed of these allocated processing routines.

The external bitmap data forms an image of the mouse cursor. Here, the external bitmap data is an image created immediately after the corresponding window is created. This image is created by allocating an empty bitmap in the window plunger and drawing it with a pen and a brush in a specified size, or internal data of the application program (a bitmap called a resource, inside the EXE file at the time of linking). (Stored in) is created by copying. The external bitmap data has the same design as the mouse cursor normally used in the monitor 16, and a dedicated one for the monitor 3 is separately stored internally in the application program (correctly in the GUI library) as a default Is designed to display this.

As shown in FIG. 5, the coordinate conversion data is the coordinate data (Xg, Yg, KXg, KYg) of the external GUI area Rg set on the display screen of the monitor 3 and the corresponding display screen of the monitor 16. Coordinate data (Xs, Y
s, KXs, KYs) and defines the association of these two regions. Here, the external GUI area Rg is an area in which the mouse cursor K is displayed in correspondence with the display screen of the monitor 16, and is set in advance in a rectangular shape for the entire display screen or a part thereof. Correspondingly, the external GUI management window Rs is allocated to the area on the monitor 16 side.

In doing so, the coordinate conversion data is actually displayed on the monitor 3 and the image display space formed by the video memory 19.
The offset value in the case where the scanning start end side does not match with the area displayed in FIG. 2 and the linear type coefficient for associating the dot pitch between the monitors 3 and 16 are shown. In this embodiment, the offset value and Coefficient is value 0 and value 1
Therefore, the address control of the video memory 19 is executed, and the monitors 3 and 16 having the same dot pitch are applied.

The operating system holds the data of a plurality of windows inside the random access memory 8 by executing these application programs. Here, the data in these windows is composed of coordinate data of the display position, data of the display form, data designating the object to which it belongs, active / inactive identification data, and the operating system is assigned to the monitor 16 at the present time. Hold these data for the window you are in. In addition, the operating system is
The contents of the window are updated according to the keyboard operation, etc.), and the window assigned to the monitor 16 is managed by this. Further, the window assigned to the monitor 16 is switched between display and active to provide a menu screen corresponding to the user's operation.

Of these, the operating system is the external GUI management window Rs for the mouse 13.
And the large-area window W1 arranged in the lower layer, and the mouse cursor is displayed. The external GUI management window Rs manages the mouse 13 in preference to the window W1. In addition, the external GUI
When the mouse cursor K is displayed in the management window Rs, the coordinate data of the mouse cursor display position is converted into coordinate data of the external GUI area Rg by the coordinate conversion data, and the mouse cursor is also displayed on the monitor 3 side. .

That is, when the application program is started up, the operating system causes the internal bitmap data stored in the operating system to be stored in the video memory 1 by the operating system according to the initial setting of the window for managing the mouse cursor.
4 and the mouse cursor K is displayed on the monitor 16.
Is displayed. Then, the application program (FIG. 5) converts the coordinate data of the mouse cursor in the external GUI area management window Rs into the coordinate data on the external GUI area Rg side. At this time, the central processing unit 9
Uses the coordinate conversion data to convert the coordinate data of the external GUI area management window Rs and the external GUI area Rg into a linear function (that is, Xs = A × Xg + B, Ys = C × Yg).
+ D), and the linear data is converted into coordinate data on the external GUI area Rg side by this linear function.

Further, the application program generates bitmap data in the application program in response to the event message of the operating system and transfers it to the video memory 19 according to the generated coordinate data. As a result, the central processing unit 9 generates a video signal S2 in which a mouse cursor having the same shape as that displayed on the monitor 16 is displayed, and this video signal S2 is combined with the video signal S1 from the video tape recorder 2 to monitor. Display in 3. In doing so, the application program converts the coordinate data of the mouse cursor displayed on the monitor 16 by the operating system into coordinate data on the monitor 3 side, and then, as shown in FIG.
The same mouse cursor as the monitor 16 is displayed on the image to be processed by a simple process of transferring the external bitmap data to the video memory 19.

FIG. 1 is a flow chart showing the processing procedure of the central processing unit 9 for moving the mouse cursor displayed in this way. When the movement of the mouse 13 is detected by the operating system, the central processing unit 9 moves from step SP1 to step SP2 and moves the mouse cursor of the monitor 16 by the operating system.

The movement of the mouse 13 is detected on the operating system by managing the window in which the mouse cursor is placed. Further, the movement of the mouse cursor on the monitor 16 updates the coordinate data of the mouse cursor for the data of the corresponding window stored in the operating system, and reads the bitmap data of the mouse cursor stored in the operating system according to the coordinate data. This is executed on the operating system by updating the contents of the video memory 14 with the read bitmap data.

When the mouse cursor of the monitor 16 is moved in this way, the operating system issues a mouse move event in step SP3 and sends an event message to the application program in step SP4.

In the application program, the destination of the mouse cursor is the external GUI area management window Rs.
It is determined whether or not it is within the range, and if a negative result is obtained here, the processing procedure is ended, and the movement of the mouse cursor is stopped on the monitor 3 side. As a result, the application program does not execute window switching processing or the like when the display screen of the monitor 3 is off. On the other hand, when the destination of the mouse cursor is within the external GUI area management window Rs, the application program uses the coordinate conversion data to transfer the mouse cursor coordinate data in the external GUI area management window Rs to the external GUI area. After converting to the coordinate data on the Rg side, the process proceeds to step SP6.

Here, the application program transfers the external bitmap data of the mouse cursor generated in the application program to the video memory 19 based on the coordinate data, and thereby the display position of the mouse cursor K on the monitor 3 is transferred. After the movement, the process moves to step SP7 to end this processing procedure. As a result, the application program converts the mouse cursor coordinate data notified by the operating system into the coordinate data on the monitor 3 side, and then transfers the external bitmap data to the video memory 19 according to the coordinate data by a simple process. , The mouse cursor displayed on the monitor 3 is moved in association with the mouse cursor displayed on the monitor 16.

In the above configuration, when the power is turned on or the reset switch is operated (FIG. 2), in the image processing apparatus 1, the start-up procedure stored in the read-only memory 7 and the random access memory 8, An operating program stored in the hard disk device 10 is started up by the central processing unit 9 according to the start-up condition, and an application program required for image processing is started up on this operating program.

As a result, in the image processing apparatus 1, according to this application program, the data of a plurality of windows allocated to the monitor 16 for operation is the display position of each window, the display form data, the data designating the object to which the window belongs. The internal bitmap data stored in the operating system together with the active and inactive identification data and held in the application program in response to an event message from the operating system is expanded in the video memory 14.
As a result, the initial screen (FIG. 3) is formed on the monitor 16.

In the image processing apparatus 1, when the operating system executes the application program, the coordinate data of the mouse cursor is displayed on the monitor 3 side in accordance with the coordinate conversion data (FIG. 4) showing the association of the coordinates between the monitors 3 and 16. It is converted into coordinate data, and external bitmap data dedicated to the monitor 3 is stored in the video memory 19 according to the coordinate data (FIG. 6). Further, after the bit map data stored in the video memory 19 is converted into the video signal S2 in the digital-analog conversion circuit 20, it is added with the video signal S1 of the video tape recorder 2 in the addition circuit 22 and displayed on the monitor 3. It

As a result, in the image processing apparatus 1, the application program converts the coordinate data of the mouse cursor displayed on the monitor 16 by the operating system into the coordinate data on the monitor 3 side, and then the external bitmap data according to the coordinate data. The same mouse cursor as that of the monitor 16 can be displayed on the image to be processed by a simple process of simply transferring it to the video memory 19.

When the mouse 13 is operated on the initial screen or the like in which the mouse cursor is displayed in this manner, an event is detected by the window managing the mouse 13, and an event processing routine of the application program corresponding to this event is detected. Is called. As a result, by executing this event processing routine in the operating system, the corresponding event processing is executed and the title or the like is added to the video signal S1.

In the operation of the mouse, the image processing apparatus 1 (FIG. 1) responds to the movement of the mouse 13 detected by the operating system through the interface circuit 11 to generate coordinate data of the mouse cursor in the external GUI management window. Are updated, and the contents of the video memory 14 are updated by the internal bitmap data stored in the application program in accordance with the updated coordinate data, whereby the monitor 16 side executes the mouse cursor movement process on the operating system. .

On the other hand, on the monitor 3 side, an event message is sent to the application program by a mouse movement event issued by the operating system in response to the movement of the mouse, whereby the operating system notifies the application program. After the coordinate data of the mouse cursor is converted into the coordinate data on the monitor 3 side, the external bitmap data dedicated to the monitor 3 is stored in the video memory 19 according to the coordinate data (FIG. 5).

As a result, in the image processing apparatus 1, the application program converts the coordinate data of the mouse cursor displayed on the monitor 16 into the coordinate data on the monitor 3 side in response to the event request issued by the operating system. The mouse cursor on the monitor 3 can be moved in synchronization with the display on the monitor 16 by a simple process of transferring the external bitmap data to the video memory 19 according to the data. Therefore, the user can execute the pointing process while confirming the mouse cursor K on the monitor 3.
The usability can be improved accordingly. Further, at this time, since these operations can be performed by using the cursor having the same shape as the monitor 16, it is possible to perform these operations without discomfort and improve usability.

According to the above configuration, the monitor 1 is operated in accordance with the coordinate conversion data that associates the coordinates between the monitors 3 and 16.
The coordinate data of the mouse cursor displayed on 6 is displayed on the monitor 3
It is converted into the coordinate data on the side, and the mouse cursor image is displayed on the monitor 3 by the external bitmap data dedicated to the monitor 3 according to the coordinate data, so that the mouse cursors linked with the monitors 3 and 16 are displayed by a simple application program. It is possible to improve the usability with a simple structure. Therefore, the development period of the application program can be shortened accordingly, and deterioration of operability can be effectively avoided.

(2) Second Embodiment FIG. 7 is a schematic diagram for explaining the operation of the image processing apparatus according to the second embodiment. The image processing apparatus according to this embodiment is the same as that of the first embodiment except that the processing procedure of the central processing unit is partly different, so that the duplicated description will be omitted.

The application program according to this embodiment holds the bitmap data of various objects in addition to the bitmap data of the mouse cursor. Here, the bitmap data of these various objects are formed in a shape that functionally corresponds to the objects provided as standard by the operating system and that is suitable for display on the monitor 3.

In response to this, the central processing unit 9 displays various objects displayed on the monitor 16 on the monitor 3 in addition to the mouse cursor. That is, the central processing unit 9 sets the operation window as the external GUI area management window Rs as shown in FIG. 7 by the application program executing a predetermined processing procedure on the operating system at the time of startup. Specifically, the central processing unit 9 transfers the data of various windows to the random access memory 8 according to the application program, and then issues a drawing request event message to the event handler.

Subsequently, the central processing unit 9 converts the coordinate data of each object G arranged in this window into the coordinate data on the monitor 3 side on the application program, and then the external bit map data corresponding to this coordinate data. Are transferred to the video memory 19. As a result, the central processing unit 9 displays the object G displayed on the monitor 16 at the corresponding display position on the monitor 3.

When the user operates the mouse to select an object with the preset objects displayed on the monitors 3 and 16, an event is notified from the window for managing the mouse. At this time, in the case of an event for switching the display of the monitor 16, the central processing unit 9 executes the processing procedure shown in FIG. 8, and thereby switches the display of the monitor 3 in synchronization with the monitor 16.

That is, the operating system moves from step SP11 to step SP12 to detect an event, and notifies the application program of the occurrence of this event in the following step SP13. This causes the operating system to continue to step SP
At 14, the event handler is activated, and the drawing request event message is issued from the event handler to the corresponding window. Further, the operating system sends the corresponding bitmap data to the video memory 14
, And the display on the monitor 16 is switched accordingly.

Subsequently, the application program moves to step SP15, where the coordinate data of the object assigned to this window is converted into the coordinate data on the monitor 3 side in the same manner as described above for the mouse cursor, and then moves to step SP16. Corresponding external bitmap data is transferred to the video memory 19. As a result, the application program displays the object on the monitor 3 in synchronization with the display on the monitor 16 and then moves to step SP17 to end this processing procedure.

This will be described concretely in consideration of the actual operation by the user. As shown in FIG. 9, the central processing unit 9 moves from step SP21 to step SP22, and the mouse 13 is operated here. , Step SP2
3, the corresponding event handler is activated by the event notification from the operating system, and the external bit map data representing the concave shape of pressing the mouse button, for example, is transferred to the video memory 19, and then step SP
Returning to step 20, the processing procedure is completed.

On the other hand, when the user releases the push button display with the mouse, the same processing procedure is repeated. In this case, in step SP25, the external bitmap data representing the convex shape for releasing the mouse button is obtained. After transferring to the video memory 19, this processing procedure is ended. In addition to the mouse operation, the central processing unit 9 switches the display on the monitor 3 in response to an instruction from an application program or an instruction from the keyboard in the same manner as switching the display on the monitor 16.

10 and 11 show the monitor 16 respectively.
4 is a schematic diagram showing actual display screens of 3 and 3. FIG. In this case, a title bar is displayed at the top of the display screen, a selection menu for objects used for editing is displayed in the center of the display screen along with option buttons, etc., and a processing mode selection menu is displayed in the lower left corner. It is designed to be.

As a result, in the image processing apparatus, the operating object is also displayed by the dedicated bitmap data in the same manner as on the monitor 16 so that the deterioration of the visibility can be effectively avoided. Further, in the application program, the corresponding object can be displayed by a simple process of simply converting the coordinates and transferring the corresponding bitmap data.

According to the second embodiment, not only the mouse cursor but also the object is converted from the coordinate data on the monitor 16 side into the coordinate data on the monitor 3 side, and according to this coordinate data, the external bitmap dedicated to the monitor 3 is used. By displaying the data on the monitor 3, it is possible to effectively avoid the deterioration of the visibility and display a menu screen similar to the monitor 16 on the image to be processed. In addition, a menu screen or the like can be switched and displayed in cooperation with the monitors 3 and 16 by a simple application program. Therefore, with such a simple structure, the usability can be further improved as compared with the first embodiment.

(3) Third Embodiment FIG. 12 is a flowchart showing the processing procedure of the central processing unit of the image processing apparatus according to the third embodiment. In the image processing apparatus according to this embodiment, except for the processing procedure of the central processing unit,
Since the image processing apparatus has the same configuration as that of the above-described embodiment, the duplicated description will be omitted.

When the central processing unit is started, the processing procedure is executed to make each window transparent on the monitor 16 side, thereby displaying the top window described above with reference to FIG. Furthermore, even when the window on the monitor 16 side is switched in response to the mouse operation,
The other windows are made transparent so that the top window of FIG. 3 is continuously displayed.

At this time, regarding this transparent window,
The application program moves from step SP31 to step SP32 to make the external GUI area management window on the monitor 16 side transparent, and then to step SP33.
Then, the coordinate data of the object assigned to the external GUI area management window is converted into coordinate data on the monitor 3 side. Further, the application program moves to step SP34, expands the external bitmap data in the video memory 19 according to the coordinate data, and then moves to step SP35 to end this processing procedure.

In the third embodiment, the monitor 16
With the entire window on the side set transparent, the coordinate data of the mouse cursor and the object is converted into coordinate data of the monitor 3, and the mouse cursor and the object are displayed on the monitor 3 by the external bitmap data dedicated to the monitor 3 according to the coordinate data. By displaying, it is possible to obtain the same effect as that of the second embodiment. Further, the user can visually check the monitor 3 that displays the processing target and execute various operations, thereby further improving the usability.

(4) Other Embodiments In the first embodiment described above, the case where the movement of the mouse cursor is stopped on the monitor 3 side when the mouse comes off the external GUI area management window has been described. However, the present invention is not limited to this, and a so-called mouse capture function may be used to acquire an event message by the mouse and execute this type of processing.
