Returning to FIG. The display correspondence unit 26 generates a composite video signal such that a video corresponding to each video signal supplied from the association determination unit 24 is displayed in each region associated with the display 2, and Output. In addition, the display corresponding unit 26 arranges the video corresponding to the video signal selected by the user in the region selected by the user according to the operation information from the display region specifying unit 29, and puts it in the region selected by the user. Is generated in the area where the video corresponding to the video signal selected by the user has been displayed (alternately replacing the areas) and output to the display 2 To do.
[0032]
The operation input unit 27 is provided on the screen of the display 2, for example, and includes an input device such as a keyboard and a mouse in addition to a transparent touch panel sensor that transmits the screen, and specifies the position of the display 2 on the screen. The display area replacement operation of the user is detected, and the coordinate information is output to the operation information holding unit 28.
[0033]
Here, the display area replacement operation of the user will be described. The user's display area replacement operation includes a first operation for selecting one of a plurality of video signals (videos) displayed on the screen and a destination area for the selected video signal (video). The second operation. For example, in the state where the video signals a to i are displayed in the areas A to I of the display 2 shown in FIG. 1, the area A where the video of the video signal a is displayed by the first operation is shown. When the area E in which the video signal e is displayed is selected by the second operation, the video of the video signal a is displayed in the area E, and the video of the video signal e is displayed in the area A. The
[0034]
Returning to FIG. The operation information holding unit 28 holds the coordinate information from the operation input unit 27 and outputs it to the display area specifying unit 29. The display area specifying unit 29 specifies which area on the screen of the display 2 corresponds to the coordinate information corresponding to the user's display area replacement operation, and displays the operation information in the display corresponding unit 26, the display area selection frequency. The data is output to the counting unit 30 and the video signal selection frequency counting unit 32.
[0035]
The display area selection frequency counting unit 30 counts the number of times each area is selected based on the coordinate information from the display area specifying unit 29 corresponding to the second operation for selecting the area, The count value for each area is output to the table γ update unit 31.
[0036]
The table γ update unit 31 updates the table γ stored in the table β and γ storage unit 25 based on the information from the display area selection frequency counting unit 30. For example, in the state where the table γ is the initial setting, when the count value for the region E exceeds a predetermined threshold, the display gaze degree index corresponding to the region E is updated to the highest dis1, and so far than the region E. The display gaze degree index corresponding to the regions A, B, C, and D where the display gaze degree index is high is updated to dis2, dis3, dis4, and dis5 by one step.
[0037]
The video signal selection frequency counting unit 32 counts the number of selected video signals based on the coordinate information from the display area specifying unit 29 corresponding to the first operation for selecting the video signal. Then, the count value for the video of each video signal is output to the table α update unit 33.
[0038]
The table α update unit 33 updates the table α stored in the table α storage unit 23 based on information from the video signal selection frequency counting unit 32. For example, in the state where the table α is the initial setting, when the count value for the video of the video signal c exceeds a predetermined threshold, the importance index corresponding to the video of the video signal c is updated to the highest class 1 so far. The importance indexes corresponding to the videos of the video signals a and b, which have a higher importance index than the video of the video signal c, are updated to class 2 and class 3, respectively, one step lower.
[0039]
Next, the operation of the video signal output apparatus 1 will be described with reference to the flowcharts of FIGS.
[0040]
In step S <b> 1, the video signal input unit 21 takes in a plurality of different video signals (for example, video signals a to i) to the video signal output device 1 and outputs them to the importance index association unit 22 and the association determination unit 24. To do.
[0041]
In step S2, the importance index associating unit 22 determines whether or not the table α (FIG. 4) stored in the table α storage unit 23 has been updated from the initial setting state. If it is determined that the table α has not been updated, the process proceeds to step S3.
[0042]
In step S <b> 3, the importance index associating unit 22 acquires the initially set table α from the table α storage unit 23. Next, in step S5, the importance index associating unit 22 refers to the acquired table α, and associates the importance signals indicating priority with the video signals a to i from the video signal input unit 21, The information is output to the association determination unit 24. That is, this process gives priority to each video signal.
[0043]
In this case, since the table α is in an initial setting state, importance indexes class 1 to 9 are associated with the video signals a to i, respectively.
[0044]
In step S6, the association determination unit 24 acquires the table β (FIG. 5) stored in the table β and γ storage unit 25, and associates the display gaze index with the video signals a to i. This process is directly a process of associating the importance index representing the importance (priority order) of the video signal with the display gaze degree index representing the importance (gaze degree) of the display area. In addition, since the importance index is associated with the video signal according to the table α, it is a process of associating the video signal with the display gaze degree.
[0045]
According to the table β, the importance indexes class1 to 9 are associated with the display gaze index dis1 to dis9, respectively. Accordingly, in this case, display gaze index dis1 to dis9 are associated with the video signals a to i, respectively.
[0046]
In step S7, the association determination unit 24 determines whether or not the table γ (FIG. 6) stored in the table β and γ storage unit 25 has been updated from the initial setting state. If it is determined that it has not been updated, the process proceeds to step S8.
[0047]
In step S <b> 8, the association determination unit 24 acquires the initially set table γ from the table β and γ storage unit 25. Next, in step S <b> 10, the association determination unit 24 refers to the acquired table γ and associates the video signals a to i from the video signal input unit 21 with the areas A to I provided in the display 2. To the display corresponding unit 26. This process is a process that directly associates a display gaze degree index indicating a degree of demand (gaze degree) with the display area (sets a priority) in the display area, but as described above. The display gaze index is associated with the importance index by the table β, and the importance index is further associated with the video signal by the table α. This is the process of associating.
[0048]
In this case, since the table γ is in an initial setting state, the display gazing indices dis1 to dis9 are associated with the areas A to I, respectively. Accordingly, areas A to I are associated with the video signals a to i, respectively.
[0049]
In step S <b> 11, the display correspondence unit 26 generates a composite video signal such that videos corresponding to the video signals a to i are displayed in the associated areas A to I based on information from the association determination unit 24. Generate and output to the display 2. In this case, as shown in FIG. 9, a composite video signal in which videos corresponding to video signals a to i are arranged in areas A to I, respectively, is generated, and the composite video signal is output to the display 2 to correspond. Will be displayed.
[0050]
In step S12 (FIG. 8), the operation input 27 determines whether or not the first operation for selecting the video of the video signal has been input, and waits until it is determined that the first operation has been input. If it is determined that the first operation has been input, the process proceeds to step S13.
[0051]
In step S <b> 13, the operation input unit 27 outputs coordinate information corresponding to the first operation to the display area specifying unit 29 via the operation information holding unit 28. The display area specifying unit 29 specifies which area on the screen of the display 2 the coordinate information corresponding to the first operation of the user corresponds, and displays the operation information as the display corresponding unit 26 and the video signal. The data is output to the selection frequency counting unit 32. The video signal selection frequency counting unit 32 counts the number of video images selected for each video signal based on the operation information corresponding to the first operation, and updates the count value for each video signal video in the table α. To the unit 33.
[0052]
In step S <b> 14, the display corresponding unit 26 is selected, for example, by blinking or changing the luminance as compared with other videos so that the video selected by the first operation can be easily recognized by the user. Display a frame around the video.
[0053]
In step S15, the operation input 27 determines whether or not a second operation for selecting a region has been input, and waits until it is determined that the second operation has been input. If it is determined that the second operation has been input, the process proceeds to step S16.
[0054]
In step S <b> 16, the operation input unit 27 outputs coordinate information corresponding to the second operation to the display area specifying unit 29 via the operation information holding unit 28. The display area specifying unit 29 specifies which area on the screen of the display 2 the coordinate information corresponding to the second operation of the user corresponds, and displays the operation information as the display corresponding unit 26 and the display area. The data is output to the selection frequency counting unit 30. The display region selection frequency counting unit 30 counts the number of selected regions based on the operation information corresponding to the second operation, and outputs the count value for each region to the table α update unit 33.
[0055]
In step S17, the display corresponding unit 26 replaces the images of the two regions on the screen in accordance with the coordinate information corresponding to the first and second operations from the display region specifying unit 29 (for the first operation). The video of the corresponding video signal is displayed in the area corresponding to the second operation, and the video of the video signal corresponding to the second operation is displayed in the area corresponding to the first operation). A signal is generated and output to the display 2.
[0056]
In step S <b> 18, the table α update unit 32 determines whether or not to update the table α stored in the table α storage unit 23 based on information from the video signal selection frequency counting unit 32. Specifically, it is determined that the table α is updated when a count value corresponding to each of the video signals a to i exceeds a predetermined reference value (for example, 30 times).
[0057]
If it is determined to update the table α, the process proceeds to step S19. In step S19, the table α update unit 32 updates the table α. If it is determined in step S18 that the table α is not updated, the process in step S19 is skipped.
[0058]
In step S <b> 20, the table γ update unit 31 determines whether to update the table γ stored in the table β and γ storage unit 25 based on the information from the display area selection frequency counting unit 30. Specifically, when a count value corresponding to each of the areas A to I exceeds a predetermined reference value (for example, 30 times), it is determined that the table γ is updated.
[0059]
If it is determined that the table γ is to be updated, the processing proceeds to step S21. In step S21, the table γ update unit 31 updates the table γ. If it is determined in step S20 that the table γ is not updated, the process in step S21 is skipped. Thereafter, the process returns to step S2, and the subsequent processes are repeated.
[0060]
In the process of step S2 after the process of step S19 or step S21, it is determined that the table α is updated from the initial setting state, and the process proceeds to step S4. In step S <b> 4, the importance index associating unit 22 acquires the updated table α from the table α storage unit 23.
[0061]
Since the processes in steps S2, S3, and S4 are processes for obtaining the table α at that time, these processes may be simply replaced with a single process of “obtaining the table α”.
[0062]
For example, if the updated table α is in the state shown in FIG. 10, in the next step S5, the video signals a, b, c, d, e, f, g, h, i are respectively assigned importance level class 5 , Class6, class2, class1, class8, class4, class9, class7, class3, and in step S6, the video signals a, b, c, d, e, f, g, h, i are respectively displayed. It is associated with the diopter index dis5, dis6, dis2, dis1, dis8, dis4, dis9, dis7, dis3.
[0063]
If it is determined in step S7 that the table γ has been updated from the initial setting, the process proceeds to step S9. In step S <b> 9, the association determination unit 24 acquires the updated table γ from the table β and γ storage unit 25.
[0064]
Since the processes in steps S7, S8, and S9 are also processes for obtaining the table γ at that time, these processes can be replaced with a single process of simply “obtaining the table γ”.
[0065]
For example, when the updated table γ is in the state shown in FIG. 11, in the next step S10, the video signals a, b, c, d, e, f, g, h, i are respectively in the regions F, I. , A, E, G, C, D, H, B. Accordingly, in the next step S11, a composite video signal as shown in FIG. 12 is displayed on the screen of the display 2. Above, description of operation | movement of the video signal output device 1 is complete | finished.
[0066]
In the above description, the tables α and γ are updated by the determination of the table α update unit 33 or the table γ update unit 31, respectively, but the user may arbitrarily set the update timing.
[0067]
In the above description, the table β is fixed without being updated, but may be arbitrarily updated by the user.
[0068]
Furthermore, in the above description, nine types of video signals are input and nine areas are provided on the screen. However, these numbers are arbitrary, and the number is less than that and more than that. Also good.
[0069]
In the above, the video signal is associated with the display area using the table α, the table β, and the table γ, but the video signal (the video signals a, b, c, d, e, f, and g of the table α is used). , H, i) and the display area (display areas A, B, C, D, E, F, G, H, I) of the table γ are directly associated with one table, and the video signal is Sort based on priority and arrange on the table in order from the top. Similarly, display areas are sorted based on the priority and arranged on the table in order from the top to display the video signal. Even if the areas always correspond to those in the same order, the same operation can be realized.
[0070]
By doing in this way, one table can be made. However, when three tables of table α, table β, and table γ are used, the priority of the video signal and the priority of the display area can be associated with an arbitrary relationship by rewriting table β. When the number of tables is one, the priority order of video signals and the priority order of display areas cannot be associated with an arbitrary relationship.
[0071]
As described above, according to the video signal output device to which the present invention is applied, a plurality of video signals can be displayed at the same time, and the video signal display area is replaced in response to the user's two operations. can do.
[0072]
Furthermore, since the video signal output apparatus to which the present invention is applied automatically updates the tables α and γ based on the user's operation, the more the user uses it, the more suitable the user's preference is displayed. .
[0073]
