DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an image display apparatus 10 according to an embodiment of the present invention.
[0018]
The image display device 10 includes a CPU 11, a video controller 12, a main memory 13, and a hard disk 14. The CPU 11 performs overall control of the image display device 10 by executing a program stored in a storage device such as the hard disk 14 or ROM using hardware resources such as the main memory 13. In the present embodiment, the storage device of the image display device 10 is described as an example of a hard disk, but a memory such as a flash memory or a compact flash (R) may be used as the storage device. . The video controller 12 includes a video chip 20 and a video memory 22, and outputs image data stored in the video memory 22 to a display 30 connected via an interface 23.
[0019]
In this specification, the image includes all information output from the video controller 12 and displayed on the display 30. Therefore, not only a still image such as a JPEG or BMP file displayed on the display 30 but also a character displayed on the display 30 is included in the image. Therefore, an image displayed by a JPEG, BMP file or the like is particularly distinguished as a still image. A moving image displayed on the display 30 is also included in the image referred to in this specification.
[0020]
The image output by the image display device 10 has a three-layer structure including layers 1 to 3 as shown in FIG. In this embodiment, layer 1 that is the backmost layer is a layer that displays a live video, and layer 2 that is positioned in front of the backmost layer is a layer that displays characters and still images. Layer 3 that is the front layer is a layer that displays scroll characters. Here, when the transparency setting is not performed for each layer, a front side image is displayed on the display 30 in a portion where the display areas overlap.
[0021]
By synthesizing and displaying the image having such a layer structure, for example, a division display screen as shown in FIG. 3C is displayed on the display 30. Here, the division display screen refers to a screen composed of a plurality of partial display areas, as shown in FIG.
[0022]
FIG. 3 is a diagram schematically showing the layer structure. FIG. 3A is a memory map of the register 21 and the video memory 22 included in the video chip 20. The register 21 stores the display position and size data of each layer.
[0023]
In the video memory 22, a layer 1 image region 221, a layer 2 image region 222, a layer 3 image region 223, and a scroll character region 224 are mapped.
[0024]
FIG. 3B is a diagram virtually showing the display state of each layer based on the display position and size data of the layer stored in the register 21 and the image data of each layer stored in the video memory 22. It is.
[0025]
In the example of FIG. 3A, based on the data set in the register 21, the partial display area in the upper right part of the screen is secured for layer 1, the entire display area is secured for layer 2, and the screen for layer 3 is A lower partial display area is secured. Here, the entire display area indicates not the entire display area of the display 30 but the entire display area of the section display screen displayed on the display 30 by the image display device 10.
[0026]
FIG. 3C shows a screen image in which the images of these three layers are combined and displayed. In layer 2, transparency is set in an area that overlaps the partial display area of layer 1 on the rearmost layer. Therefore, the rearmost layer 1 is also displayed on the combined section display screen. The foremost layer 3 is displayed so as to hide the lower area of layer 2.
[0027]
As described above, the image display device 10 according to the present embodiment can output various segmented display screens segmented by the partial display area by setting the display position and size of each layer in the register 21. is there. The display contents can be determined by setting the contents of the image to be displayed on each layer and the background / transparency setting information in the video memory 22.
[0028]
Information of each layer stored in the register 21 and the video memory 22 is determined by the segment display setting data 41 stored in the hard disk 14. The hard disk 14 stores a plurality of segment display setting data 41 in order to display a plurality of various segment display screens on the display 30.
[0029]
FIG. 4 is a diagram showing a list of file names of the category display setting data 41. As shown in FIG. As shown in the figure, in this embodiment, the section display setting data 41 is an HTML file. Each segment display setting data 41 includes display position information (x, y coordinates), size information (width and height), background color setting information, and transparency setting information of the three layers constituting each display image. It is.
[0030]
The CPU 11 reads the segment display setting data 41 according to a predetermined program, interprets the contents of the segment display setting data 41, and sends a drawing instruction to the video chip 20. The video chip 20 writes the display position and size data of each layer in the register 21 according to this drawing instruction, and also writes the image data of each layer in the video memory 22.
[0031]
As described above, it is possible to display one section display screen by using one section display setting data 41. However, the image display apparatus 10 is a schedule data for automatically switching the section display screen as time passes. 42 is provided. The schedule data 42 includes regular schedule data 421 and interrupt schedule data 422, and is stored in the hard disk 14.
[0032]
FIG. 5 is a diagram showing an example of the contents of the steady schedule data 421. As shown in FIG. In the figure, [main01], [main02]... [Main05] represent the display order of the division display screen. In the example shown in the figure, in the initial screen, the screen 001. Using an html file, screen001. The section display screen displayed based on the html file is displayed for 60 seconds. Next, screen 004. Using the html file, screen004. The section display screen displayed based on the html file is displayed for 120 seconds. Next, the screen 002. Using the html file, screen002. The segment display screen displayed based on the html file is displayed for 240 seconds. In this way, the division display screen displayed on the display 30 is sequentially switched.
[0033]
Such switching control is executed by the CPU 11 reading the schedule data 42 according to a predetermined program. The CPU 11 sequentially reads and interprets the corresponding category display setting data 41 according to the description contents of the read steady schedule data 421 and sends a drawing instruction to the video chip 20. Then, the video chip 20 performs update processing of the register 21 and the video memory 22.
[0034]
FIG. 6 is a diagram showing the contents of the interrupt schedule data 422 used when the interrupt screen display becomes necessary. The case where the interrupt screen is required is a case where the initial processing of the video chip 20 is necessary and it is determined that the image displayed on the display is disturbed. When an interrupt screen is required, the CPU 11 reads the interrupt schedule data 422. Then, the CPU 11 performs control to interrupt the schedule described in the steady schedule data 421 and display the interrupt screen.
[0035]
In the figure, as the segment display setting data 41 for generating the interrupt screen, screen010. html is specified. If an interrupt screen is required, screen010. The interruption screen is displayed for 20 seconds in accordance with the html file, and then the screen transition control is performed by returning to the schedule described in the steady schedule data 421.
[0036]
The case where the initial processing of the video chip 20 is necessary will be specifically described. As shown in FIG. 3A, when various types of information are set in the register 21 and the video memory 22 in accordance with instructions from the CPU 11, the video chip 20 outputs image data to the display 30 based on these information. . Here, when the contents of the video memory 22 are changed, the video chip 20 can reflect the changed contents on the display 30 in real time. However, when the display position or size of each layer is changed, the video chip 20 must change the contents of the register 21, that is, perform the initial process, and change the area of the corresponding layer secured in the video memory 22. I must. Therefore, for the layer in which the size or the display position is changed during that period, display switching on the display 30 cannot be performed in real time. During the initial process, the output image to the display 30 is disturbed, so in this embodiment, the interrupt screen is displayed as described above.
[0037]
In the present embodiment, as the interrupt screen, a screen including the layer 2 in which the size of the layer is the entire display area, the layer 2 in which the transparency setting is not performed, and the layer 3 in which the transparency setting is performed on the entire layer is used. To do. By using a screen having such a layer configuration as an interrupt screen, layer 2 is displayed on the entire display 30. As a result, the display on the display is not affected while the layer display position change and the size change are performed for layer 1 and layer 3.
[0038]
As described above, in the present embodiment, the size of layer 2 of the interrupt screen is set as the entire display area, but layer 2 of the interrupt screen only needs to have an area that can completely hide the partial display area of layer 1, The entire display area is not necessarily required.
[0039]
In this embodiment, layer 2 sandwiched between layer 1 and layer 3 is used as an interrupt screen, but the foreground layer may be used as the interrupt screen. In this case, if all the partial display areas of the other layers are hidden by the foreground layer, there is no need to transparently set the other layers.
[0040]
That is, according to the present invention, the display on the display 30 is arranged by displaying the layer without the change of the display area in front of the layer with the change of the display area. Alternatively, the display on the display 30 is adjusted by transparently setting the layer whose display area has been changed.
[0041]
FIG. 7 is a diagram illustrating an example of the transition of the category display screen. In the figure, a state is shown in which the six segment display screens SC1 to SC6 transition. Of these, the division display screen SC6 is an interrupt screen, and is therefore referred to as an interrupt screen SC6.
[0042]
The interrupt screen SC6 displays the screen 010.10 described in the interrupt schedule data 422 shown in FIG. It is a screen generated by an html file. On the other hand, the segment display screens SC1 to SC5 are screens generated by the segment display setting data 41 described in the steady schedule data 421 shown in FIG.
[0043]
Then, when the division display screens are sequentially switched according to the steady schedule data 421 shown in FIG. 5, the video chip 20 does not need to perform the initial process during the transition SC1 → SC2 → SC3 → SC4. Alternatively, the initial processing of the video chip 20 is necessary, but the display on the display is not disturbed. Therefore, during the transition SC1 → SC2 → SC3 → SC4, the segment display screen transits according to the steady schedule data 421.
[0044]
On the other hand, the transition SC4 → SC5 is a screen transition that requires the initial processing of the video chip 20 and disturbs the display on the display. Therefore, the interrupt schedule data 422 is read and the interrupt screen SC6 is displayed. As a result, the transition is made from SC4 to SC6 to SC5, but the display on the display 30 is not disturbed during this time.
[0045]
The details of the processing flow of the image display apparatus 10 of the present embodiment described above will be described with reference to the flowcharts of FIGS.
[0046]
FIG. 8 is a flowchart of the main schedule process. The main schedule process is an operation of a predetermined program executed on the CPU 11. First, the CPU 11 reads the steady schedule data 421 (step S1). Then, according to the schedule described in the steady schedule data 421, the division display setting data 41 for the initial screen is read, the division display setting data 41 is interpreted, and a drawing instruction is sent to the video chip 20. In accordance with this instruction, the video chip 20 sets various information in the register 21 and the video memory 22. Then, the video chip 20 outputs the segment display screen data to the display 30 according to the setting contents of the register 21 and the video memory 22. Thereby, an initial screen is displayed on the display 30 (step S2).
[0047]
Next, the CPU 11 determines whether or not the update time of the screen described in the steady schedule data 421 has elapsed (step S3), and if the update time has elapsed (Yes in step S3). Then, it is determined whether or not an interrupt screen needs to be displayed (step S4). Specifically, it is determined whether or not the video chip 20 requires initial processing and the screen transition is disturbed by the display on the display. If the update time has not elapsed (No in step S3), the process of step S3 is executed again after the predetermined time has elapsed.
[0048]
When the interrupt screen needs to be displayed, the CPU 11 reads the interrupt schedule data 422, interprets the interrupt schedule data 422, and sends a drawing instruction to the video chip 20. In accordance with this instruction, the video chip 20 sets various information in the register 21 and the video memory 22. The video chip 20 outputs interrupt screen data to the display 30 in accordance with the setting contents of the register 21 and the video memory 22. As a result, an interrupt screen is displayed on the display 30 (step S2).
[0049]
Next, the CPU 11 reads the segment display setting data 41 for the next screen according to the original schedule described in the steady schedule data 421, interprets the segment display setting data 41, and sends a drawing instruction to the video chip 20. The video chip 20 sets various information in the register 21 and the video memory 22 in accordance with this instruction. Then, the video chip 20 outputs the segment display screen data to the display 30 according to the setting contents of the register 21 and the video memory 22. Thereby, the next screen is displayed on the display 30 (step S6).
[0050]
On the other hand, if it is determined in step S4 that it is not necessary to display the interrupt screen, the CPU 11 executes the next screen display process according to the original schedule described in the steady schedule data 421 (step S6).
[0051]
If the screen displayed in step S6 is the final screen (Yes in step S7), the main schedule process is terminated. If there is a next screen (No in step S7), the process returns to step S3 to repeat the process. Do.
[0052]
In this way, the segment display screen displayed on the display 30 is automatically switched sequentially. When it is determined that the initial processing of the video chip 20 is necessary and the display on the display is disturbed, the interrupt screen is controlled to be inserted. The display on 30 is not disturbed.
[0053]
Next, details of the processing in steps S2, S5, and S6 in the flowchart shown in FIG. 8 will be described with reference to FIGS.
[0054]
FIG. 9 is a flowchart of the screen display process, which is a process common to steps S2, S5, and S6. First, the CPU 11 and the video chip 20 perform setting processing for layers 1 to 3 in accordance with the segment display setting data 41 (steps S10 to S30). Specifically, in accordance with an instruction from the CPU 11, the video chip 20 sets the display position and size data of layers 1 to 3 in the register 21, and sets image data to be displayed on the layers 1 to 3 in the video memory 22.
[0055]
Next, the video chip 20 performs layer 1 to layer 3 combining processing according to the setting contents of the register 21 and the video memory 22, and outputs the segment display screen data to the display 30 (step S40).
[0056]
FIG. 10 is a flowchart showing details of the layer 1 setting process (step S10). In the layer 1 setting process, first, the display position and size of the layer are set in the register 21 (step S11). Next, in this embodiment, since layer 1 is a live video display layer, video capture processing is executed at 30 fps (frame per second), and the captured video is sequentially stored in the layer 1 image area of the video memory 22. It is stored in 221 (step S12).
[0057]
FIG. 11 is a flowchart showing details of the layer 2 setting process (step S20). In the layer 2 setting process, first, the display position and size of the layer are set in the register 21 (step S21). Then, background color setting and transparency setting are performed for layer 2 (step S22). For example, a process for transparently setting a portion that displays a live video of layer 1 is performed. In addition, a background color for character display is set.
[0058]
Next, in this embodiment, since layer 2 is a display layer for characters and still images, a process for writing these pieces of information is performed.
[0059]
First, it is determined whether or not the clock display needs to be changed (step S23). Here, since the clock display is updated every minute, when one minute has passed (Yes in step S23), the current time data is written in the clock display position of the layer 2 image area 222 (step S24). ).
[0060]
Next, it is determined whether or not the weather display needs to be changed (step S25). Here, the CPU 11 can receive weather change information from the outside by a predetermined program. If the weather has changed (Yes in step S25), the current weather data is written in the weather display position of the layer 2 image area 222 (step S26).
[0061]
Next, it is determined whether or not the still image (JPEG) needs to be changed (step S27). The change timing of the still image is described in the segment display setting data 41. If the still image needs to be changed (Yes in step S27), the still image data is written in the still image display position of the layer 2 image area 222 (step S28). Through the above process, the layer 2 setting process is performed.
[0062]
FIG. 12 is a flowchart showing details of the layer 3 setting process (step S30). First, the display position and size of the layer are set in the register 21 (step S31). Then, background color setting and transparency setting are performed for layer 2 (step S32).
[0063]
Next, in this embodiment, since the layer 3 is a scroll character display layer, the writing process of these pieces of information is performed.
[0064]
First, it is determined whether or not the scroll character string needs to be changed (step S33). The change timing of the scroll character example is described in the segment display setting data 41. If the scroll character string needs to be changed (Yes in step S33), the changed scroll character string is written in the scroll character area 224 (step S34).
[0065]
Next, the bit block of the scroll character string stored in the scroll character area 224 is transferred to the layer 3 image area 223 (step S35). Then, the display position of the scroll character string in the layer 3 image area 223 is incremented to the left (step S36). The layer 3 setting process is performed by the above process.
[0066]
In this way, when the layer 1 to 3 setting process (steps S10 to S30) is executed and the register 21 and the video memory 22 of the video chip 20 are updated, the composite drawing process (step S40) by the video chip 20 is performed. ) Is executed, and the division display screen is displayed on the display 30.
[0067]
The classification display screen is changed by the processing as described above. Next, the flow of processing will be described using the transition of the segment display screens SC1 → SC2 → SC3 → SC4 among the screen transitions shown in FIG.
[0068]
FIG. 13 is a flowchart regarding the display processing of the division display screen SC2, that is, the transition from SC1 to SC2. On the segment display screen SC1, the live video of layer 1 is not displayed because it is hidden behind the layer 2. However, it is assumed that the same display position and the same size data as the layer 1 on the division display screen SC2 are written in the register 21 as the display position and size of the layer 1. Accordingly, the display position and size of layer 1 are not changed here.
[0069]
In this transition, first, the transparency setting is performed for the area to be transparent of layer 2, that is, the area overlapping with the partial display area of layer 1 (step S101). Next, layer 2 image data is created. Specifically, clock, weather forecast, and still image data are written in the layer 2 image area 222 (step S102).
[0070]
Further, in the transition from SC1 to SC2, the display position and size of layer 3 are not changed. Finally, composite display processing of layers 1, 2, and 3 is performed (step S103).
[0071]
Thus, in the transition from SC1 to SC2, the display position and size of layer 1 and layer 3 are not changed. In addition, since the layer 2 is fixed to the size of the entire display area, the display position and size of the layer 2 are not changed. Therefore, in the transition from SC1 to SC2, the division of the division display screen that is actually displayed on the display 30 is changed.
[0072]
FIG. 14 is a flowchart relating to the display processing of the division display screen SC3, that is, the transition from SC2 to SC3. On the division display screen SC3, the characters of layer 2 are displayed in the entire area. The display position and size of layer 1 are not changed.
[0073]
In this transition, first, the background color of layer 2 is designated. However, the transparency setting is not performed (step S201). Next, layer 2 image data is created. Specifically, the character data for the entire display area is written in the layer 2 image area 222 (step S202).
[0074]
In the transition from SC2 to SC3, the display position and size of layer 3 are not changed. The entire layer 3 is set to be transparent (step S203). Finally, composite display processing of layers 1, 2, and 3 is performed (step S204).
[0075]
Thus, in the transition from SC2 to SC3, the display position and size of layer 1 and layer 3 are not changed. In addition, since the layer 2 is fixed to the size of the entire display area, the display position and size of the layer 2 are not changed. Therefore, in the transition from SC2 to SC3, the section of the section display screen that is actually displayed on the display 30 is changed, but the initial processing of the video chip 20 is not necessary, so there is no display disturbance.
[0076]
FIG. 15 explains the display processing of the division display screen SC4, that is, the transition from SC3 to SC4.
[0077]
First, the display position and size of layer 1 are changed (step S301). Next, the transparency setting is performed for the area of Layer 2 that is desired to be transmitted, that is, the area that overlaps the partial display area of Layer 1 (step S302). Next, layer 2 image data is created. Specifically, weather forecast and still image data are written in the layer 2 image area 222 (step S303). Further, the display position and size of layer 3 are changed (step S304). Finally, composite display processing of layers 1, 2, and 3 is performed (step S103).
[0078]
Thus, in the transition from SC3 to SC4, the display position and size of layer 1 and layer 3 are changed. However, during the transition process from SC3 to SC4, the character data of layer 2 is displayed in the entire display area. Therefore, in the transition from SC3 to SC4, the initial processing of the video chip 20 is performed, but there is no display disturbance on the display 30.
[0079]
In this way, even when the initial processing of the video chip 20 is necessary, the schedule data 42 is created so as not to disturb the display. That is, when the division display screen SC2 is compared with the division display screen SC4, the display positions and sizes of the layers 1 and 3 are changed. Therefore, when the transition from SC2 to SC4 is executed, display disturbance occurs. Therefore, such a problem is solved by interposing the division display screen SC3 as a display adjustment screen.
[0080]
On the other hand, there is no schedule between the segment display screen SC4 and the segment display screen SC5 corresponding to the segment display screen (display adjustment screen) SC3 for adjusting the display. In such a case, as described above, the interrupt screen SC6 is inserted to arrange the display.
[0081]
As described above, one of the points of the present invention is to automatically insert an interrupt screen when the initial processing of the video chip 20 is required. Thereby, since the display on the display is not disturbed, it is possible to create a schedule without considering the necessity of the initial processing of the video chip. Another point of the present invention is to create schedule data 42 that does not cause disturbance in display even when initial processing of the video chip 20 is required. In this case, the display can be arranged without requiring an interrupt screen.
[0082]
