[0031]
Referring back 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 of the associated areas of 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 area selected by the user according to the operation information from the display area specifying unit 29, and shifts the video to the area selected by the user. A video signal corresponding to the video signal selected by the user is generated in the area where the video corresponding to the video signal selected by the user is displayed (the area is alternately replaced) and output to the display 2 I do.
[0032]
The operation input unit 27 is provided, for example, on the screen of the display 2 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 a position on the screen of the display 2. The display area replacement operation by 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 of selecting one of a plurality of video signals (videos) displayed on the screen and a movement destination area of the selected video signal (video). The second operation is For example, in a state where the images of the video signals a to i are displayed in the regions A to I of the display 2 shown in FIG. 1 respectively, the region A in which the image of the video signal a is displayed by the first operation is displayed. When the region E in which the image of the image signal e is displayed is selected by the second operation, the image of the image signal a is displayed in the region E, and the image of the image signal e is displayed in the region A. You.
[0034]
Referring back to FIG. The operation information holding unit 28 holds the coordinate information from the operation input unit 27 and outputs the coordinate information 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 display area replacing operation by the user, and stores the operation information in the display corresponding unit 26, the display area selection frequency. Output to the counting section 30 and the video signal selection frequency counting section 32.
[0035]

[0036]
The table γ updating 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, if the count value for the region E exceeds a predetermined threshold, the display gaze index corresponding to the region E is updated to the highest dis1, and the display gaze index is higher than that of the region E until now. The display gaze index corresponding to the regions A, B, C, and D where the display gaze index is high is updated by one step to dis2, dis3, dis4, and dis5, respectively.
[0037]
The video signal selection frequency counting unit 32 counts the number of each video signal selected based on the coordinate information from the display area specifying unit 29 corresponding to the first operation of selecting the video signal. , And outputs the count value for the video of each video signal to the table α updating unit 33.
[0038]
The table α updating unit 33 updates the table α stored in the table α storage unit 23 based on the information from the video signal selection frequency counting unit 32. For example, when the count value for the video of the video signal c exceeds a predetermined threshold value in the state where the table α is the initial setting, the importance index corresponding to the video of the video signal c is updated to the highest class1, and The importance index corresponding to the video of the video signals a and b whose importance index is higher than that of the video of the video signal c is updated to class2 and class3, respectively, one step lower.
[0039]
Next, the operation of the video signal output device 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) into the video signal output device 1 and outputs the video signals to the importance index association unit 22 and the association determination unit 24. I 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 default state. If it is determined that the table α has not been updated, the process proceeds to step S3.
[0042]
In step S3, the importance index associating unit 22 acquires the default 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 to associate the video signals a to i from the video signal input unit 21 with the priority indexes indicating the priority, The information is output to the association determination unit 24. That is, the priority is given to each video signal by this processing.
[0043]
In this case, since the table α is in the initial setting state, the video signals a to i are associated with importance indexes class1 to class9, 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 a process of directly associating the importance index indicating the importance (priority) of the video signal with the display gaze index indicating the importance (gaze) of the display area, as described above. In addition, since the importance index is associated with the video signal by the table α, the process is to associate the video signal with the display fixation degree.
[0045]
According to the table β, the importance indexes class1 to class9 are associated with the display gaze index dis1 to dis9, respectively. Accordingly, in this case, the display gaze indexes 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 default 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 an initial setting table γ from the table β and γ storage unit 25. Next, in step S10, the association determination unit 24 refers to the acquired table γ to associate the video signals a to i from the video signal input unit 21 with the regions A to I provided in the display 2 and , To the display correspondence unit 26. In addition, this process is a process of directly associating the display gaze index indicating the demand (gaze) with the display area with the display area of the display (setting the priority order), as described above. Since 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, the video signal is eventually displayed in the display area. This is the process of associating.
[0048]
In this case, since the table γ is in the initial setting state, the display gaze indexes dis1 to dis9 are associated with the regions A to I, respectively. Therefore, the areas A to I are associated with the video signals a to i, respectively.
[0049]
In step S11, based on the information from the association determination unit 24, the display correspondence unit 26 generates a composite video signal such that the video corresponding to the video signals a to i is displayed in the associated areas A to I. Generate and output to the display 2. In this case, as shown in FIG. 9, a video corresponding to the video signals a to i is generated as a composite video signal arranged in the areas A to I, and the composite video signal is output to the display 2, and Is 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 S13, the operation input unit 27 outputs the 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 corresponds to the coordinate information corresponding to the first operation of the user, and displays the operation information in the display corresponding unit 26 and the video signal. 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 the video image of each video signal in the table α. Output to the unit 33.
[0052]
In step S14, the display corresponding unit 26 displays, for example, blinks, changes the luminance compared to other images, or selects the image so that the user can easily recognize the image selected by the first operation. Or display a frame around the image.
[0053]
In step S15, the operation input 27 determines whether a second operation for selecting an area 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 S16, the operation input unit 27 outputs the 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 user's second operation corresponds to and displays the operation information on the display corresponding unit 26 and the display area. Output to the selection frequency counting unit 30. Display area selection frequency counting section 30 counts the number of selected areas based on operation information corresponding to the second operation, and outputs a count value for each area to table α updating section 33.
[0055]
In step S17, the display corresponding unit 26 replaces the images of the two regions on the screen according to the coordinate information corresponding to the first and second operations from the display region specifying unit 29 (the first operation A video of the corresponding video signal is displayed in the area corresponding to the second operation, and a 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 S18, the table α updating unit 32 determines whether to update the table α stored in the table α storage unit 23 based on the information from the video signal selection frequency counting unit 32. Specifically, when a count value exceeding a predetermined reference value (for example, 30 times) among the count values corresponding to the images of the image signals a to i appears, it is determined that the table α is updated.
[0057]
If it is determined that the table α should be updated, the process proceeds to step S19. In step S19, the table α updating unit 32 updates the table α. If it is determined in step S18 that the table α is not updated, the processing in step S19 is skipped.
[0058]
In step S20, the table γ updating 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 exceeding a predetermined reference value (for example, 30 times) among the count values corresponding to the regions A to I appears, it is determined that the table γ is updated.
[0059]
If it is determined that the table γ is to be updated, the process proceeds to step S21. In step S21, the table γ updating unit 31 updates the table γ. If it is determined in step S20 that the table γ is not updated, the processing 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 has been updated from the initial setting state, and the process proceeds to step S4. In step S4, the importance index associating unit 22 acquires the updated table α from the table α storage unit 23.
[0061]
Note that the processes in steps S2, S3, and S4 are, after all, processes for obtaining the table α at that time, and therefore, these processes may be simply replaced with one process of “acquiring the table α”.
[0062]
For example, when 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, and i are respectively assigned to the importance index class5. , Class6, class2, class1, class8, class4, class9, class7, and class3. In step S6, the video signals a, b, c, d, e, f, g, h, and i are respectively displayed on the display. It is associated with the gaze 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 S9, the association determination unit 24 obtains the updated table γ from the table β and γ storage units 25.
[0064]
In addition, since the processes of steps S7, S8, and S9 are also processes for acquiring the table γ at that time, these processes can be replaced with one process of simply “acquiring 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, and i are stored in the regions F, I, respectively. , A, E, G, C, D, H, B. Therefore, in the next step S11, a composite video signal as shown in FIG. 12 is displayed on the screen of the display 2. This is the end of the description of the operation of the video signal output device 1.
[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 be allowed to set the update timing arbitrarily.
[0067]
In the above description, the table β is fixed without being updated, but may be arbitrarily updated by the user.
[0068]
Further, 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 even if the number is smaller or larger, the number is larger. Is also good.
[0069]
In the above description, 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 signal a, b, c, d, e, f, g of the table α) is used. , H, i) and the display areas (display areas A, B, C, D, E, F, G, H, I of the table γ) are directly associated in one table, and the video signal is Sorted based on priority and arranged on the table in order from the top.Similarly, the display area is sorted based on the priority and arranged on the table in order from the top. The same operation can be realized even when the regions always correspond in the same order.
[0070]
By doing so, the number of tables can be reduced to one. However, when the three tables of the table α, the table β, and the 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 the table β. When the number of tables is one, the priority of the video signal and the priority of the display area cannot be associated with any 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 display area of the video signal is replaced in response to two operations by the user. can do.
[0072]
Further, the video signal output device to which the present invention is applied automatically updates the tables α and γ based on the operation of the user, so that the more the user uses the table, the more suitable the display is for the user's preference. .
