Here, it is assumed that the transparency can be linearly designated between 0 and 1 by the transparency designation signal 35. For example, when the transparency is 0, the result is the same as when the window display parallel data 46 is output as it is. Is 0.3, the value of the window display parallel data is combined with the ratio of 70% and the value of the first parallel data at a ratio of 30%, and is output as the superimposed display data 48.
[0034]
FIG. 4 is a block diagram showing the internal configuration of the resolution / frequency conversion unit 47 shown in FIG.

The write control unit 55 generates a write control signal 54 that is a timing signal for writing the resolution-converted data 52 in the window screen storage unit 58 from the resolution-converted synchronization signal 51.
[0036]
The read control unit 57 displays the data of the display screen of the device connected to the sub display data 39 as a window on the display screen of the device connected as the main display data 38. A read control signal 58 for reading data from the window screen storage unit 54 is generated in accordance with the window display position from the first synchronization signal 45 and the display position designation signal 34. The window storage unit 58 stores the display data 52 after resolution conversion for one screen according to the write control signal 54, reads it according to the read control signal 56, and outputs it as window display parallel data 46.
[0037]
FIG. 5 shows a display example of the monitor device 7 in the embodiment of the present invention.
In FIG. 5, a window screen 60 is displayed so as to overlap the main screen 59. The mouse cursor 61 is a mouse cursor in the information processing terminal displayed on the main screen 59. The transparency of the window screen is variable, and when the transparency is increased, the display of the window screen becomes lighter, and the background main screen can be seen instead.
[0038]
In the display of the window screen 60, three properties of position, size, and transparency are used. These properties can be controlled from external devices such as the first PC 4, the second PC 5, and the video output device 6 that are connected by communication signals, and therefore can be indirectly operated by the keyboard 2 and the mouse 3. However, in the present embodiment, when the position or size of the window is changed by dragging the frame portion of the window with the mouse 3, the position information of the mouse cursor and the information on the mouse button pressing status are controlled from the PC side. It is necessary to change the display position signal transmitted to the display unit 29 and output to the display control unit 27 in accordance with the display position of the window in the communication control unit 29.
[0039]
In addition, by transmitting the position information of the mouse cursor to the communication control unit 29, the communication control unit 29 calculates the distance between the mouse cursor and the window, and when the mouse cursor approaches the window, the window control is automatically performed. Increase transparency. This is to make the operation on the main screen smooth by temporarily making the window semi-transparent when the mouse cursor approaches the window.
[0040]
In addition, in an OS (Operating System) that uses windows, a window that is currently valid as a work target is called an active window. Information on the position and size of such rectangular active area is controlled by communication. When the active area and the area of the window screen 60 in FIG. 5 overlap with each other as in the case of the mouse cursor, the transparency of the window screen 60 is automatically increased, It is possible to perform control so as not to hinder the work on the screen 59.
[0041]
In FIG. 2, the voice control unit 28 can individually adjust the volume level of the first voice data 19, the second voice data 20, and the third voice data 21 that are input voice data. At this time, it is also possible to automatically adjust the audio playback level corresponding to the device displayed in the window according to its transparency. In this case, when no display is performed (= transparency is 1), no sound is output, when the transparency is 0.5, the volume level is 0.5, and when the transparency is 0, the volume level is 1 (full gauge). Take control. As a result, for example, as the window display fades out, the corresponding sound can be faded out.
[0042]
In FIG. 3, the signal status data 31 output from the display data monitoring unit 37 is notified to the communication control unit 29, where the communication control unit 29 displays the display in the display control unit 27 according to the change status of the signal status data 31. A control signal is transmitted to the changeover switch 40, the input device signal control unit 26, and the voice control unit 28.
[0043]
For example, when the input signal is interrupted only in the main screen from the state in which the signal is normally input to both the main screen and the window screen, the communication control unit 29 grasps the change from the signal status data 31, and as a countermeasure, The display data displayed on the window screen is switched to the display on the main screen, and at the same time, the keyboard and mouse connection is newly switched to the device displayed on the main screen.
[0044]
Further, when the display data signal for the window is in a sleep state, the window is made semi-transparent, and when the window is cut, control is performed such that the transparency is maximized and the window becomes invisible.
[0045]
As described above, the window display / control device (output data control device) 1 includes means for inputting a plurality of image data (output images) from a plurality of information processing terminals or video output devices 6, and inputs thereof. A means for combining and outputting a plurality of image data in one screen using a main screen and a window screen, and calculating a ratio of displaying the window screen superimposed on the main screen as transparency, and displaying the window screen as transparency And means for performing data communication with the information processing terminal and the video output device.
[0046]
Further, the window display / control device 1 has a function of automatically changing the transparency of the window screen display according to the position of the mouse cursor in the main screen.
[0047]
The window display / control apparatus 1 has a function of automatically changing the transparency of the window screen display according to the position of the active area in the main screen.
[0048]
In addition, the window display / control device 1 depends on a signal state output from a connected device (a device connected to the window display / control device 1 such as the display control unit 27 and the first PC, the second PC, and the video output device 6). It has a function to automatically change the transparency of the window screen display.
[0049]
The window display / control apparatus 1 has a function of adjusting the playback level of the audio output from the corresponding input device according to the transparency of the window screen display.
[0050]
Embodiment 2. FIG.
In this embodiment, a specific operation for changing the transparency of the window will be described.
As an example, a case will be described in which a number of windows are simultaneously displayed on one screen in an OS using a window display used in a personal computer (personal computer) or a workstation.
Of the plurality of displayed windows, the window currently being subjected to the input / output operation is defined as an “active window”.
[0051]
FIG. 6 shows a display screen example of this embodiment.
63 is a main screen, and 64 and 65 are window screens. Here, it is assumed that the window screen 65 is the current active window (active screen).
In this case, the distance between the window screen 64 and the window screen 65 as the active window is calculated using the upper left coordinates and the lower right coordinates of each rectangular area (in the case of FIG. 6, the window screen 64 and the window screen). 65 is the interval of opening in the vertical direction).
Therefore, since the window screen 64 and the window screen 65 do not overlap, it is determined that it is not necessary to control the display of the window screen 64 using transparency.
When there is an overlap between the window screen 64 and the window screen 65, the display of the window screen 64 is controlled using transparency.
[0052]
Next, consider a case where the main screen 63 is an active window.
In this case, the area of the active window (main screen 63) overlaps the display areas of the window screen 64 and the window screen 65, and the distance between them becomes “0”. In such a case, control is performed so that the transparency of the window screens 64 and 65 is automatically increased so that the screen of the active window area can be seen.
The control is not to make the display area semi-transparent only when the display area overlaps and the distance is 0, but it can be controlled so that the transparency gradually increases from a certain distance. The “fixed distance” is specified by the user from an external PC (first PC 4, second PC 5, etc.).
FIG. 7 shows an example of a conversion curve that associates distance with transparency.
The correspondence between the distance designated by the user and the transparency is stored in the transparency calculation unit 70.
A similar method is used for automatic control of transparency according to the position of the mouse cursor.
[0053]
An example of a specific method (operation) for realizing the above mechanism will be described.
(1) The coordinates of the mouse cursor are periodically transmitted from the PC to the communication control unit 29. At this time, the coordinates are normalized to values from 0 to 1 in both the vertical direction and the horizontal direction, and transmitted. For example, if the screen resolution of the PC is 1024 × 768 and the position of the mouse cursor is (768, 384), the normalized coordinates are (0.75, 0.5).
(2) In the window display / control apparatus 1, the coordinate information of the display area of the “window screen” is similarly set to (X1, X2, Y1, Y2) = (0.62, 0.95, 0.05, 0. As in 4), the start position and end position of the area in the horizontal and vertical directions are stored.
[0054]
(3) The distance between the mouse cursor and the “window screen” is calculated from the coordinates of the mouse cursor in (1) and the coordinates indicating the area of the window screen in (2). The calculation method is not special, and an algorithm for obtaining a distance between general figures is used.
(4) The transparency of the “window screen” is changed according to the distance obtained in (3). As an example of conversion, a conversion curve as shown in FIG. 7 as an example is used. The example of FIG. 7 shows an example of conversion in which the transparency increases as the distance decreases.
Data for converting the transparency based on FIG. 7 is input in advance by the user and stored in the communication control unit 29.
[0055]
If you want to automatically control the transparency based on the position of the active area instead of the mouse cursor, the coordinate data sent from the PC is not for one point, but for two points such as the upper left and lower right coordinates of the rectangular area. The screen display can be changed by changing the transparency using the same method.
[0056]
Embodiment 3 FIG.
In the first embodiment, the resolution / frequency conversion unit 47 in the display control unit 27 stores the data that does not reflect the transparency of the window in the window storage unit 58, and then the video composition unit 49 specifies the transparency designation. The image is synthesized using the signal 35, but when the image is stored in the window storage unit 58 in the resolution / frequency conversion unit 47, the first parallel data 41 and the transparency designation signal 35 are also input and input. Data that is combined with the first parallel data 41 reflecting the transparency at the time may be stored. In this case, it is not necessary to input the transparency designation signal 35 in the video composition unit 49, and the first parallel data 41 and the window according to the display position designation signal 34 just like the data switching unit 62 in the conventional example of FIG. The display parallel data 46 may be switched and output.
[0057]
Embodiment 4 FIG.
Further, in the first embodiment, one signal of the display position designation signal 34 and the transparency designation signal 35 is individually used in the display control unit 27, but “when the value of the transparency designation signal 35 is 1,” By assuming that it is not a window area, it is possible to omit the display position designation signal.
[0058]
Embodiment 5 FIG.
In the first embodiment, the position information of the mouse cursor and the information on the click state are transmitted from the PC side to the communication control unit 29 in the window display / control device 1, where the positional relationship between the window and the mouse cursor is calculated, The control of each control unit is performed, but conversely, window position data is transmitted from the window display / control device 1 side to the PC side, and the positional relationship between the position of the mouse cursor and the window is set inside the PC. The same effect can be obtained by calculating and transmitting a control command (for example, designation of transparency) to the window display / control apparatus according to the result.
[0059]
【The invention's effect】
As described above, according to the window display / control device of the present invention, the transparency of the window display can be changed even when the output display data of another device is displayed in the window on the main screen. It is possible to confirm both display data on the window screen at the same time.
[0060]
In addition, by adding a function that automatically increases the transparency of the window display when the mouse cursor approaches the window in the main screen, when operating on the main screen in the area hidden in the window in the past Since it is possible to execute an operation that cannot be performed without moving or deleting the window once without performing any operation such as moving or deleting the window, improvement in work efficiency can be expected.
[0061]
It is also possible to expect improvement in work efficiency by adding a function for automatically increasing the transparency of the window depending on the position of the active area (such as the area where the active window is displayed in the window OS) on the main screen.
[0062]
In addition, since the window display can be made translucent by an input signal from a connected device (device connected to the window display / control device 1, such as the display control unit 27, the first PC, the second PC, and the video output device 6), the connection The status of the device can be judged visually.
