The application program 200 transmits the area attribute information 250 including the attribute information and the area information generated as described above to the operating system 210.
To the image display device 110 via the
The display attribute of the moving image display screen 812 is changed to high contrast by the specific area display attribute conversion unit 113 of 0 to display the display data.

Area attribute information 2 generated as described above
Several expression formats are conceivable for the 50 area information as follows.

FIG. 9 is a diagram showing an outline of area information of a single display area according to the present embodiment. As shown in FIG. 9, the area information of a single display area indicates the relationship between the window A displayed on the image display device 110 and changing the display attribute and the input synchronization signal. Generally, an image signal output from the information processing apparatus 100 is a predetermined period (a so-called back porch period) from the trailing edge of the horizontal and vertical synchronization signals.
Image display is started after (THFP, TVFP period in the figure).
The display period (THD, TVD period in the figure) is determined by the display resolution.

For example, a video graphic adapter (Vi
The image signal of the video graphic adapter (VGA) specification has 640 dots horizontally and 480 lines vertically, and the maximum value of the coordinate axes (X, Y) on the display screen of FIG. 9 is (640, 480). Here, one dot is one cycle of a clock signal (a so-called dot clock) used on the information processing apparatus 100 side to generate an image signal.

As described above, in order to accurately know the start position (x0, y0) and end position (x1, y1) of the rectangular window A on the image display device 110, the information processing device 100
From the side, it can be seen that it is necessary to transmit at least the information of the horizontal and vertical back porch periods, the information of the display resolution, the dot clock frequency or cycle, and the above-mentioned window start position coordinates and end position coordinates.

The case where the absolute area information of the rectangular window A is transmitted has been described above. However, the start position (x0, y0), the number of dots in the horizontal window display period, and the vertical window display The position of the window A can be similarly specified by the number of lines in the period.

Further, as the area information of the window, the reference position is set to two-dimensional XY coordinates (0, 0) with reference to the trailing edges of the horizontal and vertical synchronization signals, and the number of dots and the number of lines from this point to the start of the window It is also possible to specify the start position and specify the window in the same manner as described above.

Further, instead of defining each of the above information by the number of dots and the number of lines, the information may be defined by the ratio to one horizontal scanning period or one vertical scanning period. For example, the area information of the window is from x1% to x2% of one horizontal scanning period with respect to the trailing edge of the horizontal synchronization signal.
From the trailing edge of the vertical synchronizing signal, it can be defined as y1 percent to y2 percent of one vertical cycle. When the window area information is defined by the ratio of the horizontal and vertical scanning periods, there is no need to know the dot clock frequency or the period information on the image display device 110 side.

FIG. 9 shows window area information for changing the display attribute of a single window portion, but it is also conceivable to change the display attribute of a plurality of windows.

FIG. 10 is a diagram showing an outline of area information of a plurality of display areas according to the present embodiment. As shown in FIG. 10, the area information of the plurality of display areas shows an example in which the display attributes of the windows A and B having no overlap are changed. In this case, the area information of the window A shown in FIG. In addition to the information, the area information of the window B is displayed on the image display device 11.
By sending the information to 0, the area information of a plurality of display areas can be sent.

As described above, in the image display system of the present embodiment, the area information of the window to be added is further defined, and the area information of a plurality of non-overlapping windows is replaced by the area information of a required number of windows. By giving the image display device 110, the display attributes of a plurality of windows can be changed.

FIG. 11 is a diagram showing an outline of area information having a shape other than a rectangle according to the present embodiment. As shown in FIG. 11, the area information of a shape other than a rectangle indicates a method of defining the area information when changing the display attribute of a window area of a shape other than a rectangle. In this case, the area information is as follows. Looks like

First, for a polygonal area such as window B, each point information of the polygon is defined. For example, n
The coordinates of the n points are defined in the polygon, and the coordinates (x1, y1), (x
2, x2),..., (Xm, ym) are defined.

For a circular or elliptical area such as the window C, information on the center coordinates (x0, y0), the horizontal diameter xc, and the vertical diameter yc is defined.
Further, the shape information indicating the shape of each of the above-mentioned area information is also specified prior to the above-mentioned area information.

FIG. 12 is a diagram showing an outline of area information formed by a plurality of overlapping display areas according to the present embodiment.
As shown in FIG. 12, in the area information formed by a plurality of overlapping display areas, there are a plurality of windows, and a method of defining the area information when each of the windows overlaps each other. In this case, the display attributes can be changed when the windows overlap.

FIG. 12A shows a case where the window B is displayed on the top surface, and FIG. 12B shows a case where the window B is partially hidden below the window A. Hereinafter, for the sake of brevity, the window A is a window having a normal display attribute, and a description will be given on the subject of appropriately displaying a window B whose display attribute has been changed on the window A on the display screen.

In the case of FIG. 12A, since all the area information of the window B is displayed, the processing can be performed in the same manner as in the case of the rectangular window described above. On the other hand, in the case of FIG. 12B, the region information is redefined as the above-described polygon information,
Alternatively, appropriate display of the window B is realized by dividing the window into a plurality of rectangular window areas and redefining the area.

In the case of defining as polygon information, FIG.
In the case where coordinate information of each black point in (b) is created and defined as a plurality of rectangular windows, for example, FIG.
As shown in (b), window B is divided into an upper rectangular window area and a lower rectangular window area to create area information. In this case, the division shown in FIG. 12B is an example, and it goes without saying that the division of the window B can be realized by another division method.

Further, in FIG. 12, when window A is also a window whose display attribute is changed in the same manner as window B, the area of each window is the same as the above-described window area in the case of overlapping of window areas. Can be defined, and the area information of each window is further added to the image display device 11.
It is also possible to convert the area information of each window into three-dimensional coordinates by adding vertical relation information on the display screen of 0. In this case, the window may be converted into three-dimensional coordinates by adding Z-axis information in the direction perpendicular to the display screen to the two-dimensional coordinates of the area information.

When the three-dimensional coordinated area information is sent to the image display device 110, the image display device 110
The specific area display attribute conversion means 113 identifies the vertical relationship between the windows and changes the display attribute of the area displayed on the top layer.

Hereinafter, examples of various information transmitted from the information processing device 100 to the image display device 110 in the image display system of the present embodiment will be described.

Input image signal amplitude (for example, 0.7 V).

Next, a description will be given of a display attribute changing process for reproducing moving image data with high contrast by the application program 200 when the display attribute of the specific area can be changed by the image display device 110 as a result of the initialization process. I do.

FIG. 15 is a flowchart showing a processing procedure of a display attribute changing process of the application program 200 of the present embodiment. As shown in FIG. 15, in the display attribute changing process of the application program 200, when the moving image data is reproduced by the application program 200, an outline of the display attribute changing process of displaying a moving image window for reproducing the moving image data with high contrast is shown. I have.

First, the application program 20 in which the user reproduces the moving image data in the process of step 1501
When 0 is activated, the application program 200 inquires the operating system 210 for a list of files storing moving image data stored on the DVD 104 or the like in the processing of step 1502.

In the processing of step 1511, the operating system 210 opens a file menu by referring to the file on the DVD 104 via the file system driver and the DVD interface.

When a list of files storing moving image data is displayed, in step 1502, the user selects a file of moving image data to be reproduced from the displayed file list.

In the processing of step 1503, when the application program 200 issues a drawing command for displaying the moving image window to the operating system 210 to display the moving image window for displaying the selected moving image data, step 1512 Operating system 210, the operating system 210 instructs the image display device driver 240 to display the moving image window using the area information designated by the drawing instruction, and as a result, the image display device 110
Displays a moving image window.

Subsequently, in the processing of step 1504, the area attribute information generating means 201 of the application program 200 determines whether the moving image window has a high contrast with the area information designated at the time of displaying the moving image window and the execution time. The region attribute information 250 is generated based on the attribute information indicating the contrast value of the moving image data set in advance as a parameter of the moving image data, and a high contrast instruction to increase the contrast of the displayed moving image window is instructed to the operating system 210.

In the processing of step 1513, the display attribute change control means 211 of the operating system 210
When the region attribute information acquiring unit 213 receives the high contrast instruction from the application program 200, the image display device 110 refers to the attribute change flag set in the initialization processing, and the image display device 110 can change the display attribute of the specific region. If there is, the USB device driver 23
The area attribute information 251 is transmitted to 0, and an instruction to increase the contrast is given.

In the process of step 1521, the USB device driver 230 assembles a command packet storing the area attribute information 251 for performing the high contrast so as to conform to the USB protocol, and

Tell 52. The image display device 110 connected to the USB controller 107 receives the command packet addressed to itself via the USB controller 115, extracts the area information and the contrast information, and changes the contrast of the specified moving image window.

In the process of step 1505, the application program 200 reads the moving image data of the selected moving image file via the file system driver and the DVD interface, transfers the read moving image data to the main memory 102, and transfers the moving image data transferred to the main memory 102. The image display device driver 240 and the display controller 1
The moving image is sent to the image display device 110 via the display device 05 and the moving image is reproduced in the moving image window whose display attribute has been changed to the high contrast value for the moving image data.

Next, in the process of step 1506, the application program 200 checks whether or not the moving image data being reproduced has ended. If there is still moving image data to be reproduced, the process returns to step 1505, where the reproduction is performed. If the moving image data to be processed ends, step 1507
Proceed to processing.

When the reproduction of the moving image data is completed,
07, the application program 20
The area attribute information generation unit 201 of area attribute information 25 for returning the display attribute of the moving image window to the default value
0 to the operating system 210
Outputs the default contrast command.

In the processing of step 1514, the display attribute change control means 211 of the operating system 210
Upon receiving a default contrast command from the application program 200 by the area attribute information acquisition unit 213, the area attribute information 251 for performing default contrast is transmitted to the USB device driver 230,
Instructs the display attribute of the video window to default contrast to return to the default value.

In the processing of step 1522, the USB device driver 230 executes the area attribute information 2 for performing the above-mentioned default contrast so as to conform to the USB protocol.
A command packet storing 51 is assembled, and the packet is sent to the USB controller 107 to return the contrast of the specified moving image window to a default value.

When the application program 200 sends a command to close the moving image window to the application program 200 in the processing of step 1508, the operating system 210 erases the moving image window in the processing of step 1515, and
0 ends the process of reproducing the moving image data.

In the above description, the attribute information indicating the contrast value of the moving image data corresponds to the application program 2
00 is set in advance as a parameter at the time of execution, but attribute information is stored together with display data in a medium such as a DVD 104 that stores display data such as moving image data, and display data is displayed. At this time, the attribute information stored together with the display data may be read from the medium, and the read attribute information may be used for changing the display attribute of the specific area.

FIG. 16 is a flowchart showing a processing procedure of a display attribute changing process based on the attribute information stored together with the moving image data according to the present embodiment. As shown in FIG. 16, in the display attribute changing process based on the attribute information stored together with the moving image data, when the moving image data is reproduced by the application program 200, the moving image data is reproduced according to the attribute information stored in the medium together with the moving image data.

When a list of files storing moving image data is displayed, in step 1502, the user selects a file of moving image data to be reproduced from the displayed file list.

After the file of the reproduced moving image data is selected, the process proceeds to step 1601 to request the operating system 210 to read the file in order to read the contrast value which is the attribute information of the selected moving image data.

In the processing of step 1602, the contrast value, which is attribute information set in advance in the selected moving image data file, is stored in the operating system 2.
10 and passes the read contrast value to the application program 200.

In the processing of step 1503, when the application program 200 issues a drawing command to display the moving image window to the operating system 210 to display the moving image window for displaying the selected moving image data, step 1512 Operating system 210, the operating system 210 instructs the image display device driver 240 to display the moving image window using the area information designated by the drawing instruction, and as a result, the image display device 110
Displays a moving image window.

Subsequently, in the process of step 1504, the area attribute information generating means 201 of the application program 200 determines the area information designated at the time of displaying the moving picture window and the selection so that the moving picture window has a high contrast. Attribute information 2 based on the attribute information indicating the contrast value of the moving image data read from the read file.
50, and instructs the operating system 210 to perform a high contrast instruction to increase the contrast of the displayed moving image window.

In the process of step 1513, the display attribute change control means 211 of the operating system 210
When the region attribute information acquiring unit 213 receives the high contrast instruction from the application program 200, the image display device 110 refers to the attribute change flag set in the initialization processing, and the image display device 110 can change the display attribute of the specific region. If there is, the USB device driver 23
The area attribute information 251 is transmitted to 0, and an instruction to increase the contrast is given.

In the process of step 1521, the USB device driver 230 assembles a command packet storing the area attribute information 251 for performing the high contrast so as to conform to the USB protocol.
07 to send the packet.

The USB controller 107 converts the received instruction packet into an electric signal,
07 in the image display device 110 connected to the
Tell 52. The image display device 110 connected to the USB controller 107 receives the command packet addressed to itself via the USB controller 115, extracts the area information and the contrast information, and changes the contrast of the specified moving image window.

In the following steps, similarly to the processing described with reference to FIG.
Reproduces the moving image data of the selected moving image file in a moving image window whose display attribute has been changed to a high contrast value for moving image data.

FIG. 17 is a diagram showing an example of a medium storing both moving image attribute information and moving image files according to the present embodiment.

In the processing of step 1802, the display attribute change control means 211 checks whether or not the generated event indicates the movement of the window in which the high contrast is being performed, and the high contrast is being performed. If the window has moved, the process proceeds to step 1805, in which the region attribute information generation unit 212 generates region attribute information 251 using the region information after the movement, and resets the contrast value of the window. It instructs the USB device driver 230.

In the process of step 1811, the USB device driver 230 sets the area attribute information 25 for resetting the contrast value so as to conform to the USB protocol.
The instruction packet storing 1 is assembled, and the packet is sent to the USB controller 107 to reset the contrast.

If the event generated in the processing of step 1802 does not indicate the movement of the window in which the high contrast is being performed, the flow advances to the processing of step 1803, and the display attribute change control means 211 executes the generated event. To see if it indicates a change in the size of the window that is undergoing high contrast.

In the same manner, it is checked whether or not an event relating to a window in which high contrast is performed has occurred. If a specific event has occurred, the process proceeds to step 1805; To end.

As described above, the area attribute information 2
The display attribute of the display screen of the image display device 110 can be updated in accordance with 50, and the display of the window on the display screen can be appropriately performed.
