Also in this case, if the graphic data and the image data are not associated with each other in step S506 (S506: No), the graphic data is drawn based on the graphic attribute value (S508). ), The graphic data is displayed on the display unit 407 (S504). When the input from the operator is an instruction input for associating the graphic data and the image data using the instruction input unit 404, the display control unit 405 updates the content of the association table storage unit 406. Then, the graphic data and the image data are associated with each other (S510). Further, the associated image data is combined with the area defined by the “composition attribute” set in the designated graphic data (S507), and the display unit 40 is displayed.
No. 7 is displayed (S504).

When the input from the operator is the instruction input for canceling the association between the graphic data and the image data using the instruction input unit 404, the display control unit 405 causes the association table storage unit Update the contents of 406 (S51
1) Cancel the combination of the graphic data and the image data (S5

The schedule is set (S513) and stored in the schedule storage unit 410 (S514). The specific input method of the schedule, the data structure, etc. will be described later.

The association table storage unit 406 stores information relating to the association between the graphic data and the image data, which is input by the operator through the instruction input unit 404, for example, in the form of a table. However, as a storage method,
The form of the table is not limited, and a method of storing in a database can be used. In correspondence with FIG. 1, it corresponds to a portion of the image data designating unit 104 that holds information regarding association between graphic data and image data.

Graphic data and image data are displayed on the display unit 407 under the control of the display control unit 405. It is the same as the display device 111 of FIG. Figure attribute value input section 4
08 receives an input regarding the change of the graphic attribute from the operator. In correspondence with FIG. 1, graphic attribute value setting means 10
6 corresponds to a portion that receives the input of the graphic attribute value and a portion of the automatic attribute value setting unit 109 that receives the input of the schedule from the operator. Here, the graphic attribute is information indicating the attribute of each graphic data as shown in FIG. 2A, and in the present embodiment, as described above, specifically, the "painting pattern" and the "painting pattern" are used. "Foreground color", "paint background color", "boundary line pattern", "boundary line width", and "boundary line color" can be specified.
It is also possible to specify another attribute value according to the processing content of 05.

Here, the "painting pattern" represents a pattern of the shape of the display area of the image data with respect to the graphic data, and as the attribute value, specifically, "vertical stripes",
It is possible to specify "horizontal stripe", "oblique stripe", "mesh", "lattice", "none", and the like. Of course, the attribute value is not limited to the exemplified values, and other painting patterns can be set.

Further, the "foreground color" means a portion where the image data should be displayed by designating the paint pattern when the "paint pattern" is set to other than "none".
Specify the color when the image data is not displayed. For example, FIG. 3 is an example in which the paint pattern is designated as “oblique stripes”, but the color displayed when the moving image data is not displayed in the shaded portion shown in FIG. This is the specified attribute.

Further, the "paint background color" designates the color of the portion where the image data is not displayed due to the designation of the paint pattern when the "paint pattern" is set to other than "none". For example, in the example of FIG. 3, it is an attribute that specifies the color of the background portion of the moving image data shown in FIG. The “boundary line pattern” is an attribute that specifies the shape of the contour portion of the graphic data. Specifically, "solid line",
It is possible to specify "dotted line", "dashed line", and the like.

The "boundary line width" is an attribute that specifies the width of the boundary line of the graphic data having the attribute specified by the above-mentioned "boundary line pattern". The "border line color" is an attribute that specifies the color of the border line of the graphic data. The composite attribute input unit 409 accepts from the operator, for each piece of graphic data, one of the attribute names of the graphic attributes described above, for example, "foreground color" or "boundary line pattern". In correspondence with FIG. 1, the composite attribute designating means 105
Of these, it corresponds to a portion that receives a designation input of a combined attribute from the operator and a portion of the combined attribute automatic setting unit 110 that receives a setting input of a schedule from the operator.

As the composition attribute input unit 409, specifically, an input device such as a mouse or a keyboard can be used, and it can be shared with the graphic data input unit 401, the graphic attribute value input unit 408 and the like. The attribute name of the graphic attribute input from the composite attribute input unit 409 is stored in the graphic data storage unit 402 with the attribute name “composite attribute”. The schedule storage unit 410 holds the correspondence relationship between the set time and the attribute when the graphic attribute and the composite attribute are automatically changed when the moving image data is reproduced based on the timing of the software timer 4051. In correspondence with FIG. 1, the attribute value automatic setting unit 109 and the combined attribute automatic setting unit 110 correspond to a portion that stores a schedule.

Here, a concrete method of inputting the schedule will be described. The image display control apparatus according to the present embodiment activates the software timer 4051 when displaying graphic data or data in which graphic data and image data are combined on the display unit 407, so that the graphic pattern is displayed after a predetermined time has elapsed. It is possible to automatically change and display attributes and composite attributes. Here, the schedule means data representing a schedule for changing the graphic attribute and the composite attribute.
That is, the position and size of graphic data after a certain time has passed as a schedule, the border width, and the like are specified in advance, so that the position, size, shape, and composite attribute of the area for combining and displaying image data can be changed. It is possible to automatically change the composite area based on the time series.

Specifically, the graphic attribute value input unit 408 or the composite attribute input unit 409 is used to specify the time at which the attribute should be changed and the graphic attribute or composite attribute after the change. For example, a screen as shown in FIG. 6 is displayed, and the time when the attribute should be changed is designated on the time axis 61, and the figure to be changed, the attribute, and the attribute value after the change are designated. Figure 7
The data structure of the schedule storage unit 410 is shown in FIG. The figure (a) represents the schedule regarding a graphic attribute, and the figure (b) represents the schedule regarding a synthetic attribute. As shown in the figure, the schedule should be changed at the time when the attribute should be changed (the part represented by "t =" in the figure), the designation of the graphic data ("rectangle 92" in the example of the figure), and the change. It consists of specifying attributes. Here, t is the software timer 40.
51 is a time unit time.

When the schedule is set as described above and the time set by the software timer 4051 has arrived, the display controller 40
5 is changed to the attribute set in the schedule stored in the schedule management unit 410, and the display unit 407
Change the display form of image data and graphic data on the screen.

The operation of the image display control apparatus according to the embodiment of the present invention configured as above will be described with reference to a concrete example. The image data management unit 103
In advance, the still image data 1 as shown in FIG.
44 and moving image data 145 are stored.
FIG. 8 is a flowchart showing the operation of the image display control device according to the present embodiment. In the description of this flowchart, the operation of the entire image display control device in the present embodiment will be described with reference to the functional block diagram of FIG. First, rectangular graphic data is created by input from the graphic data input means 101 (step S).
801, S802). This is from the keyboard "rectangle,
40, 30, 200, 150 ”, or the like, or after the figure shape is specified using a pointing device such as a mouse, the position and size of the figure may be specified by dragging and input. .

Various values as shown in FIG. 2A are set as initial values of the graphic attributes of the created graphic data (step S803), and then stored in the graphic data management unit 102 ( Step S804). This graphic is displayed on the display device 111 as a rectangle 91 in FIG. 9A (step S811). The initial values of these graphic attributes can be changed using the graphic attribute value setting means 106 (steps S801 and S80).
5). In this embodiment, a table as shown in FIGS. 2A to 2D is displayed on the display device 111, and the reverse display cursor 21 as shown in FIG. The attribute type is specified and the value to be set is input. Besides using the cursor, it is also possible to use the mouse pointer to directly specify the type of attribute to be set.

As a result, the graphic attribute of the rectangle 91 created earlier is changed to each value as shown in FIG. 2B, and the attribute data of the rectangle 91 stored in the graphic data management unit 102 is changed ( Step S806). At this point, the rectangle 91 and the still image data 144 or the moving image data 145 are not yet associated with each other. That is, since the “composite image” attribute of the rectangle 91 is “none” (step S809), the rectangle 91 is redrawn on the display device 111 as a rectangle 92 in FIG. 9A (step S815, S811).

The composition attribute designating means 105 is shown in FIG.
One of the attribute values shown in (a) can be designated (steps S801 and S807). For example, like the attribute value setting by the graphic attribute value setting means 106,
Using the table as shown in FIG. 2A, the "composite attribute" is designated by using the cursor, and one of the attribute types is designated.

In this embodiment, as shown in FIG. 2A, the "composite attribute" is already set to "background color" as the initial value when the rectangle 91 is created. Change to "view" (Fig. 2 (b)). As a result, the value of the "composite attribute" of the rectangle 92 stored in the graphic data management unit 102 is also changed (step S808).
Even at this point, the rectangle 92 and the still image data 144,
Since the moving image data 145 has not been associated (step S809), the display is updated in steps S815 and S811, but the actual display remains the rectangle 92 of FIG. 9A and remains unchanged.

The above steps are repeated, and FIG.
As shown in (b), in addition to the rectangle 92 created above, an ellipse 93 and a closed curve 94 are created, their graphic attribute values are changed, and "composite attributes" are designated. FIG. 2C shows an ellipse 9
3 is a set value of the graphic attribute for 3 and FIG. 2D is a set value of the graphic attribute for the closed curve 94. Next, the image data designating unit 104 designates the ellipse 93 and inputs the identifier of the moving image data 145 to associate the ellipse 93 with the moving image data 145 (steps S801 and S8).
12). As a result, "moving image 145" is set as the attribute value of the "composite image" of the ellipse 93 stored in the graphic data management unit 102.

In the ellipse 93, as shown in FIG.
Since the “background color” is specified as the value of the “composite attribute”, the image combining unit 107 sets the ellipse 93 as the image combining area.
Image composition is performed as shown in FIG. 10A using the entire background portion of (step S810), and the moving image 145 is displayed on the entire elliptical background portion (step S811). At this time, the moving image 145 is enlarged or reduced so that it has the same size as the rectangular area surrounding the ellipse 93.

Similarly, when the image data designating means 104 associates the rectangle 92 with the still image data 144, the value of the "composite attribute" of the rectangle 92 is "foreground color", so that the stripe portion is As shown in FIG.
The still image data 144 is combined and displayed. Again, the still image 144 is scaled up or down to be the same size as the rectangle 92.

Further, by the image data designating means 104,
It is also possible to cancel the correspondence between the figure and the image data. For example, if the correspondence between the ellipse and the moving image 145 is canceled from the state of FIG. 10B (steps S801 and S81).
3), the composite display using the ellipse background area is canceled (step S814), the value of the ellipse attribute “composite image” stored in the graphic data management unit 102 is reset to “none”, and As shown in 10 (c), the ellipse returns to the initial display state, and only the rectangle and the still image 144 are combined and redrawn (step S811).

Next, from the state of FIG. 10B, the graphic attribute value setting means 106 changes the rectangular "painting pattern" from "oblique stripes" to "vertical stripes" (steps S801 and S8).
05) and the rectangular "painting pattern" attribute value stored in the graphic data management unit 102 is set to "vertical stripes" (step S806). Since the rectangle is associated with the still image 144 (step S809), the image combining area is reset according to the "vertical stripe" that is the new "painting pattern", and the rectangular vertical stripe is formed as shown in FIG. The still image 144 is combined in the area (step S810) and displayed on the display device 111 (step S811).

Similarly, from the state shown in FIG. 10B, when the "painting pattern" of the ellipse is changed from "mesh" to "horizontal stripe" by the graphic attribute value setting means 106, the entire ellipse area is already used for composition. Therefore, the value of the “painting pattern” attribute of the ellipse stored in the graphic data management unit 102 is changed to “horizontal stripe” (step S806), and nothing is actually performed in steps S810 and S811. I can't.

Further, from the state of FIG. 10B, the composite attribute designating means 105 changes the "composite attribute" of the rectangle from "foreground color" to "paint background color" (step S80).
1, S807) and the value of the "composite attribute" of the rectangle stored in the graphic data management unit 102 is changed (step S808). Since the rectangle is associated with the still image 144 (step S809), the image compositing area is reset according to the new "composite attribute" value "painting background color", as shown in FIG. In FIG. 10B, the still image 144 is combined with the part that is not the image combining area (step S810) and displayed on the display device 111.

Here, the automatic attribute value setting unit 109 is shown in FIG.
It is assumed that the schedule as shown in FIG. 7A is set in the combined attribute automatic setting unit 110 as shown in FIG. 7B. In the state of FIG. 11B, t =
When the timekeeping means 108 is activated to 0, the attribute value automatic setting unit 109 instructs the figure attribute value setting means 106 to t = 10.
It is instructed to change the position of the rectangle 92 to (220, 140) and to change the painting pattern to "vertical stripes".
The position of the rectangle 92 is changed along with the change of the image combination area, and the image is redrawn on the display device 111 as shown in FIG.

At t = 11, the automatic attribute value setting unit 109 also instructs the graphic attribute value setting means 106 to change the position of the rectangle 92 to (220, 100) and the painting pattern to "horizontal stripes". Then, the image is redrawn on the display device 111 as shown in FIG. At t = 12, the attribute value automatic setting unit 109 instructs the graphic attribute value setting means 106 to
At the same time as changing the position of the rectangle 92 to (220, 60), the composite attribute automatic setting unit 110 causes the composite attribute designating means 1 to operate.
05 is instructed to set the value of the “composite attribute” to “background”, the rectangle 92 is changed to the position (220, 60), and the image is combined and displayed in the entire rectangle (FIG. 11). (C)).

As described above, according to the present embodiment, the area where the graphic data and the image data are combined and displayed can be designated as the attribute value of the graphic data, and further, these designations can be automatically changed with the passage of time. By doing so
It is possible to easily specify the position and shape of a complicated composite area. It should be noted that in the present embodiment, the image data is enlarged or reduced so as to have the same size as the rectangular area surrounding the graphic data, but the combined display is performed. The image may be combined and displayed by aligning it with the end of the rectangular area surrounding the figure (for example, the upper left edge) or by aligning the center of the image with the center of the rectangular area surrounding the figure.

Further, as shown in FIGS. 12 (a) and 12 (b),
The image data may be distorted and combined according to the shape of the figure. Also, as the schedule to be executed by the attribute value automatic setting unit, an example of changing the "position" and "painting pattern" of the figure was given, but of course other attribute values such as the size of the figure and the thickness of the boundary line You can change it freely.

When the size of the graphic data associated with the image is changed, the size of the image may be dynamically enlarged or reduced according to the size, or the size of the image may not be changed. Alternatively, the visible range of the image may be changed. For example, when the figure is reduced, a part of the image is displayed so that it cannot be seen (FIG. 12C), and when the figure is enlarged, a margin is displayed around the image (FIG. 12).
(D)) is also possible.

The present invention can also be realized by a program, and by recording this on a recording medium such as a floppy disk and transferring it, it can be easily implemented by another independent computer system.
