FIG. 6 shows an example after adjustment, FIG. 6 shows an example in which a shield (book) is placed on a display screen in which video, time, e-mail, and Internet information are overlapped. FIG. 7 shows an example of a display information management table. FIG.
[0008]
In FIG. 1, the display device of the present invention includes a camera sensor 1, a weight sensor 2, an input device 3, a display unit 4, a shielding object position / size determination unit 5, and a display position / size information management unit 6. A display overlap / blank determination unit 7, a display position adjustment / display control unit 8, and an input control unit 9.
[0009]
The camera sensor 1 and the weight sensor 2 are sensors that output position-related information for detecting a position / size where a shield (book) is placed. For example, a total of four camera sensors 1 are provided at four corners on the display screen (desk) of the display device. The camera sensors 1 have a viewing angle from the left end 0 degrees to the right end 90 degrees when viewed from the camera sensor 1 and are shielded. When the object (book) is placed, the angle α from the left end 0 degree to the left end of the shield (book) and the angle β from the left end 0 degree to the right end of the shield (book) are measured. This is output as (related) position related information (α, β). When the shielding object (book) is not placed, the position related information is (0, 0). The weight sensor 2 is provided on the entire surface of the display screen (desk) of the display device so that m × n pieces are provided at equal intervals in m rows × n columns, and when the shield (book) is placed, the shield (book). The position-related information (m, n) is output only from the weight sensor 2 positioned below. When the shielding object (book) is not placed, the position related information is (0, 0).
[0010]
The input device 3 includes a remote controller, a panel, and the like, and performs an input operation of the display device. As shown in FIG. 2, the display unit 4 has a display screen on the surface of the desk, and can display necessary information such as a TV program, Internet information, and time. In the example shown in FIG. 2, the video is displayed on the entire display screen, and the digital time is displayed on the upper left. Since the display unit 4 is composed of a desk, it is naturally possible to work on it, and it is also possible to place books and other objects.
[0011]
The shielding object position / size determination unit 5 detects the position / size of the shielding object (book) based on the position related information input from the camera sensor 1 or the weight sensor 2.
[0012]
When there is an input from the camera sensor 1, position-related information (α, β) of four angles obtained from a total of four camera sensors 1 provided at the four corners is input, a predetermined calculation is performed, and shielding is performed. The position / size information (X, Y; xxy) of the object (book) is output. Here, the position related information (X, Y) is an XY coordinate in which the upper left corner of the display screen (desk) is (0, 0), and represents the XY coordinate of the upper left corner of the shield (book). x × y) represents the horizontal and vertical lengths of the shield (book) (display position in the display information management table (see FIG. 7) of the display position / size information management unit 6 described later (see FIG. 7)). X, Y) and display size (x × y) have the same meaning). FIG. 3 is a diagram representing position / size information (X, Y; xxy) obtained from the example of the book (shielding object) in FIG. In FIG. 3, video and digital time are also displayed, and it can be seen that the position-related information (X, Y) of the shielding object (book), video, and digital time are all (0, 0).
[0013]
When there is an input from the weight sensor 2, the position related information (m, n) is input only from the weight sensor 2 that senses that the shield (book) is placed, and a predetermined calculation is performed. Similarly to the case where there is an input from the camera sensor 1, the position / size information (X, Y; xxy) of the shielding object (book) is output.
[0014]
The purpose is to prevent the shield placed on the desk surface and the window in the display screen from overlapping, and the position / size information (X, Y; xxy) of the shield (book) is Since the accuracy is not required, the shielding object position / size determination unit performs the predetermined calculation by assuming that the shielding object (book) is placed at an oblique position even if it is placed at an oblique position. 5 is configured.
[0015]
When the position related information from both sensors is only (0, 0), information indicating that there is no shielding object is output. The input from both sensors is configured to give priority to one sensor.
[0016]
The display position / size information management unit 6 includes a display information management table illustrated in FIG. 7, and display position / size information (X, Y; xx) of each display unit obtained from the display position adjustment / display control unit 8. y) is input and stored in the display information management table, and the display position / size information (X, Y; xxy) of each display unit is output to the display overlap / blank determination unit 7. In the display information management table of FIG. 7, the display position related information (X, Y) and the display size information (xx) are as described above. The importance level information represents the priority of each display unit. The display form information indicates how and where each display unit is displayed. The usage status information indicates whether the display screen is used for display or whether the displayed window is in an active state or an inactive state. The example of FIG. 7 shows the display status of the display screen of FIG. The display screen of FIG. 6 shows a state in which the e-mail information is displayed on the front of the video and the net information obtained from the Internet is displayed after the video and the digital time are displayed. Accordingly, the net information window is currently active, the e-mail information window is inactive, the digital time is displayed in the foreground, and the video is not substantially displayed (in FIG. 6, the video is not displayed). The part that doesn't overlap is displayed, but it's important that you can see everything in the video).
[0017]
The display overlap / blank determination unit 7 receives the position / size information (X, Y; xxy) of the shielding object (book) from the shielding object position / size determination unit 5 and the display position / size information management unit 6. The display position / size information (X, Y; xxy) of each display unit currently displayed is input, and the overlapping part based on the position / size information (X, Y; xxy) is input. Display position adjustment and display control based on the display unit name (digital time, video) overlapping the shield (book) and position / size information (X, Y; xxy) of the shield (book). To the unit 8. When information indicating that there is no shielding object is obtained from the shielding object position / size determination unit 5, only the display position / size information (X, Y; xxy) of each display unit currently displayed is displayed. If there is a blank, information indicating that there is a blank is output to the display position adjustment / display control unit 8.
[0018]
The display position adjustment / display control unit 8 displays the overlapping display unit name (digital time, video) from the display overlap / blank determination unit 7 and the position / size information (X, Y; xxy) of the shield (book). 4), as shown in FIG. 4, the digital time is moved to the upper right corner where it is visible, and the display position and display size of the video are adjusted so that the image is not hidden. Specifically, in the digital time, the size information (xx) is not changed, and only the position related information (0, 0) is changed to the corresponding position related information (X, Y) in the upper right corner. In addition, the video is changed so that the position related information (0, 0) is out of the range of the shielding object (book) so that the entire video is displayed in a reduced size. Along with this change, the size information (x × y) is changed to size information (x ′ × y ′). In this way, by changing and adjusting the position / size information (X, Y; xxy), an image hidden by the shield (book) is displayed. In other words, it is displayed avoiding books.
[0019]
When information indicating that there is a blank is obtained from the display overlap / blank determination unit 7, the display position / size information (X, Y; xxy) of each display unit currently displayed is deleted so as to eliminate the blank. change. Specifically, for example, as shown in FIG. 5, the position-related information (X ′, Y ′) is changed to position-related information (0, 0) so that the video is enlarged and displayed. In accordance with this change, the size information (x ′ × y ′) is changed to size information (x × y). Although the digital time is not changed, it may be returned to the upper left corner. Note that the technique for avoiding the overlap of the display position adjustment / display control unit 8 is also described in the above-mentioned Japanese Patent Application Laid-Open No. 3-269487, and is not described in detail here.
[0020]
The display screen information adjusted by the display position adjustment / display control unit 8 is output to the display unit 4 and displayed. Further, the position / size information (X, Y; xxy) of each display unit after the change is output to the display position / size information management unit 6. Further, based on a display instruction from the input control unit 9, control is performed so that a specific display unit is displayed on the display unit 4. For example, when the information indicating that the digital time is displayed is obtained, the digital time is displayed on the display unit 4, and the information indicating that the digital time is displayed is output to the display position / size information management unit 6. The time usage column in the management table is rewritten to “in use” (other than the usage column is registered). Similarly, when receiving an instruction to read and display e-mail information or net information from the Internet, the e-mail information or net information is displayed on the display unit 4 as well as the mail information or net information in the display information management table. The usage status column is rewritten to “inactive” or “active” (other than the usage status column is registered). When displaying e-mail information or net information, the display position adjustment / display control unit 8 adjusts this display to give priority to display of video. The display position / size information management unit 6 also displays the position / size information (X, Y; xx) of the display unit that is “active” when the usage status column in the display information management table is “active”. y) (and digital time position / size information (X, Y; xxy)) only is output to the display overlap / blank determination unit 7.
[0021]
The input control unit 9 reads out and displays information related to screen display from various information input by an input operation of the input device 3, for example, information indicating that digital time is displayed, or e-mail information or net information from the Internet. This information is determined and output to the display position adjustment / display control unit 8.
[0022]
In the state where “video” and “digital time” of FIG. 2 are displayed, if “book” is placed in the upper left corner, any sensor outputs position related information. The shielding object position / size determination unit 5 detects the position / size where the “book” is placed based on the position related information, and outputs the position / size information of the “book”. The display overlap / blank determination unit 7 determines an overlapped portion based on the position / size information of “book” and the display position / size information of “video” and “digital time” currently displayed, The display unit name (“video” and “digital time”) overlapping “book” and the position / size information of “book” are output. The display position adjustment / display control unit 8 moves the “digital time” from the overlapping display unit name and the “book” position / size information to the upper right corner where it can be seen, as shown in FIG. The “video” is adjusted so as to be reduced and displayed in the lower right direction so that the image is not hidden. In this way, “book” is avoided and displayed. If the “book” is removed in this state, the portion where the “book” is placed on the display screen becomes a blank portion of the display. This is detected and the display position adjustment / display control unit 8 The “video” that has been reduced in size is adjusted so as to be enlarged and displayed in the upper left direction, and then returned to the original as shown in FIG. Note that “digital time” has no inconvenience and is not restored and remains as it is.
[0023]
FIG. 6 shows an example in which a shield (book) is placed on a display screen in which information of display units of “video”, “digital time”, “e-mail information”, and “net information” are overlapped. . That is, as shown in the usage state of the display information management table in FIG. 7, the display unit “dialog” having the highest importance is not used and is not displayed, and the display having the second importance and the third importance is displayed. While the units “video” and “digital time” are being used, the display unit “e-mail information” with the importance level 4 is read out in front of the “video” using the input device 3. In the state where the display unit “net information” having the fourth importance obtained from the Internet is read and displayed, a shield (book) is placed on the display screen. In the situation of FIG. 6, the “net information” window is in an active state, “digital time” is displayed in the upper right corner in the foreground, “video” is not substantially displayed, and the “email information” window is displayed. Is inactive.
[0024]
In the situation of FIG. 6, as shown in FIG. 6, the shielding object (book) is placed in the upper left corner, and the position / size information (X, Y; Even if (x × y) is output, only the position / size information (X, Y; xx y) of the display units of “net information” and “digital time” is overlapped from the display position / size information management unit 6. Since it is output to the blank determination unit 7, the display overlap / blank determination unit 7 determines that there is no display overlap and outputs nothing. Accordingly, the display position adjustment / display control unit 8 makes no adjustment. In the situation of FIG. 6, there is no problem even if the shielding object (book) is placed in the upper left corner, so that there is no inconvenience even if the display position adjustment / display control unit 8 does not make any adjustments.
[0025]
On the other hand, when the shielding object (book) is placed in the upper right corner in the situation of FIG. 6, the position / size information (X, Y; xxy) from the shielding object position / size determination unit 5 and the display position are displayed. The display unit position and size information (X, Y; xxy) of “net information” and “digital time” from the size information management unit 6 are overlapped by the display overlap / blank determination unit 7 Judge and output to that effect. Then, the display position adjustment / display control unit 8 moves the “digital time” from the overlapping display unit name and the “book” position / size information to the upper left corner where it can be seen, and the “net information” Adjust so that the image is reduced and displayed downward so that the image is not hidden. At that time, only the size of the window is reduced without changing the size of the character.
[0026]
Note that the “dialog” must be displayed at the time of a display request, so that it is displayed at the center of the most empty space so that the display is never hidden.
[0027]
【The invention's effect】
As described above, according to the present invention, in the display device in which the surface of the desk on which the work is performed is also used as the display screen, not only the multiple windows in the display screen do not overlap, The effect is that the shield placed on the surface and the window in the display screen do not overlap, in other words, the shield placed on the surface of the desk can be prevented from hiding the window in the display screen. There is.
