6 to 7 illustrate an example of arranging objects on a background screen and setting display attributes of a plurality of objects according to the signage content generation method illustrated in FIG. 5.

The user first sets a background image on the blank screen (FIGS. 6A and 6B). Then, the user adds a display area of the text object and the image object to be displayed on the background screen (FIG. 6C). Meanwhile, the display area of the text object and the image object may form different layers. If the display time of the text object and the image object forming different layers overlap, and the display area also overlaps, the object forming the upper layer among the two may be displayed.

Then, the user selects an image object to be displayed in the image object display area, and sets display properties of the selected image object (FIG. 6D). Referring to FIG. 6D, a plurality of image objects are overlapped and displayed in the image object display area. This means that the plurality of image objects have the same display area but different display times.

Then, the user inputs text to be displayed in the text object display area and sets its display attribute (FIG. 7A). Referring to FIG. 7A, a plurality of text objects are overlapped and displayed in the text object display area. This means that a plurality of text objects having the same display area but different display times may be arranged in the same display area.

FIG. 7B illustrates a user interface for setting display attributes of a text object provided by the signage content generating apparatus 100 according to the present invention. Referring to FIG. 7B, it can be seen that the display attribute of the text object may include a font, a size, a color, and a font of the text.

8 is a flowchart illustrating another example of a signage content generation method according to the present invention. Hereinafter, the signage content generation method will be described with reference to necessary drawings.

A user places a first image object and a text object object on a background image in an execution screen of the signage content generating apparatus 100 according to the present invention, and sets display properties for each of the first image object and the text object. (S200).

Then, the signage content generating apparatus 100 converts the text object into a second image object, and replaces the text object with the second image object in the signage content configuration (S210). In this case, the display area of the second image object may be the same as the display area of the text object, and the display time of the second image object may be the same as the display time of the text object.

Then, the signage content generating apparatus 100 generates a third image object by merging the first and second image objects with respect to the overlapping display interval of the first image object and the second image object ( S230). This means that the signage content generating apparatus 100 may simplify or simplify the signage content by merging an image object corresponding to a text object and another image object in the overlapping display section described above.

Then, the signage content generating device 100 automatically sets display properties of the third image object based on the display properties of the first and second image objects (S230), and the first and second devices. The display property of the image object is automatically reset (S240). As a result, the third image object may replace the first and second image objects in the overlapping display section of the first and second image objects.

As described above, according to the signage content generation method, the text object and the image object are merged into one image object. In this case, the type of the object constituting the signage content and the size of the signage content are reduced. Therefore, the hardware and / or software configuration of the signage content playback apparatus 300 according to the present invention, which plays back signage content generated according to the signage content generation method, plays back existing signage content. This can be simplified compared to the configuration of the playback apparatus.

For example, since the signage content generating apparatus 100 converts a text object into an image object, the signage content playing apparatus 300 does not need to perform foreign language recognition, font recognition, or the like on the text object.

In addition, the resource utilization efficiency of the signage content playback device 300 for playing signage content generated according to the signage content generation method may also be increased.

9 and 10 illustrate examples in which a text object and an image object are merged according to the signage content generation method illustrated in FIG. 8.

Referring to FIG. 9, it can be seen that the signage content generating apparatus 100 according to the present invention may generate a new image object by merging a background image and a text object. In the example shown in FIG. 9, even when the text object is merged into a background image and one image, the colors of pixels (hereinafter, referred to as raw pixels) other than the portion where the text is actually displayed remain unchanged. It can be seen that.

In addition, referring to FIG. 10, the signage content generating apparatus 100 may recognize that a new image object may be generated by merging a specific image object and a text object. However, in the example of FIG. 10, when the text object is merged with a specific image object, it can be seen that low-pixels of the text object are transparently processed.

On the other hand, when the image object generated based on the text object is merged with another image object, the signage content generating device 100 in the display area overlapping the display area of the generated image object and the other image object, The generated image object may be displayed on the other image object.

11 is a flowchart illustrating an example of a method of converting a text object into an image object in the signage content generating apparatus 100 according to the present invention. Hereinafter, the conversion method will be described with reference to necessary drawings.

The signage content generating apparatus 100 renders an image corresponding to the display area of the selected text object among the text objects selected by the user and allocated to the text object display area (S211). The image rendered in the memory may have a horizontal X vertical size of the selected text object.

Then, the signage content generating apparatus 100 renders the text included in the text object on the image rendered in the memory (S212). Next, the signage content generating apparatus 100 stores the image object as an image object corresponding to the selected text object (S213).

In the conversion method illustrated in FIG. 11, processing of low-pixels of a text object as transparent pixels is not performed. Therefore, the result of merging the image object generated according to the conversion method with the background image may be as shown in FIG. 9.

12 is a flowchart illustrating a specific example of a method of converting a text object into an image object in the signage content generating apparatus 100 according to the present invention. Hereinafter, the conversion method will be described with reference to necessary drawings.

First, the signage content generating apparatus 100 renders an image of a BMP (bitmap) format having an area occupied by a display area of the selected text on a memory (S214). Then, the signage content generating apparatus 100 renders the text included in the selected text object on the rendered BMP format image (S215).

Next, the signage content generating apparatus 100 converts the image of the BMP format into an image of a portable network graphics (PMG) format and processes the low-pixels as transparent pixels (S216). This is because a process of processing pixels as transparent pixels cannot be performed in an BMP format image. Next, the signage content generating apparatus 100 stores the PNG format image as an image object corresponding to the selected text object (S217).

In the conversion method illustrated in FIG. 12, unlike the conversion method of FIG. 11, processing of low-pixels of a text object as transparent pixels is performed. Therefore, the result of merging the image object with the background image generated according to the conversion method may be as shown in FIG. 10.

Meanwhile, in the process of converting a text object into an image object in the signage content generating apparatus 100 according to the present invention, the rendered image format is not limited to the BMP format. The format is not limited to the PMG format.

FIG. 13 illustrates a process of converting a text object into an image object according to the object conversion method illustrated in FIG. 12.

The signage content generating apparatus 100 according to the present invention first renders an image of a BMP format corresponding to a display area of a text object on a memory (FIG. 13A). Then, the signage content generating device 100 renders the text "Special" included in the text object on the rendered image (FIG. 13B).

Images in BMP format cannot be processed with transparent pixels. Therefore, the signage content generating apparatus 100 converts the image in the BMP format in which the text is rendered into an image in PNG format, and then processes the low-pixels into transparent pixels (Fig. 13 (c)).

FIG. 14 is a flowchart illustrating an example of a process of setting or resetting display attributes of first to third image objects according to the signage content generation method illustrated in FIG. 8. Hereinafter, the process will be described with reference to necessary drawings.

When the third image object is generated, the signage content generating apparatus 100 according to the present invention includes an area including a display area of a second image object converted from text and a first image object merged with the second image object. Is set as the display area of the third image object (S231). The signage content generating apparatus 100 sets the overlapping display section of the first and second image objects as the display time of the third image object (S232).

Meanwhile, the signage content generating apparatus 100 excludes overlapping display sections of the first and second image objects from the display sections of the first and second image objects (S241). However, the signage content generating apparatus 100 maintains display attributes of the first and second image objects as they are in sections other than the overlapping display sections of the first and second image objects (S242).

When the above-described processes are performed, the third image object becomes an object corresponding to the overlapping display section of the text object and the second image object in the signage content.

FIG. 15 schematically illustrates a process of performing the signage content generating method illustrated in FIG. 8.

The display time of the text object is T1 to T2, the display time of the first image object is T3 to T4, and the overlapping display section of the text object and the first image object is T3 to T4 (Fig. 15 (a), (b)). The signage content generating apparatus 100 converts the text object to generate a second image object (FIG. 15C). The display time of the second image object is the same as the display time of the text object, and the overlapping display period of the second image object and the first image object is T3 to T2.

The first and second image objects are merged by the signage content generating apparatus 100 to generate a third image object, and the display time of the third image object is overlapping display of the first and second image objects. It is a section T3-T2 (FIG. 15 (d)).

FIG. 15E illustrates the configuration of the final signage content generated by the signage content generating apparatus 100. Referring to FIG. Referring to FIG. 15E, in the T1 to T3 sections, the second image object converted into the text object is a third image object in T3 to T2 which is an overlapping display section of the text object and the first image object. In T2 to T4, it can be seen that the first image object composes the signage content.

16 is a flowchart illustrating still another example of a signage content generating method according to the present invention. Hereinafter, the signage content generation method will be described with reference to necessary drawings.

The user places the first and second image object objects on the background image on the execution screen of the signage content generating apparatus 100 according to the present invention, and sets display properties for each of the first and second image objects ( S300).

Then, the signage content generating apparatus 100 generates a third image object by merging the first and second image objects with respect to the overlapping display interval of the first image object and the second image object (S310). ). This means that the signage content generating apparatus 100 may simplify or simplify the signage content by merging a plurality of image objects in the overlapping display section described above.

Then, the signage content generating apparatus 100 automatically sets display properties of the third image object based on the display properties of the first and second image objects (S320), and the first and second devices. The display property of the image object is automatically reset (S330). As a result, the third image object may replace the first and second image objects in the overlapping display section of the first and second image objects.

As described above, according to the signage content generation method, a plurality of image objects are merged into one image object. In this case, the type of the object constituting the signage content and the size of the signage content are reduced. Therefore, the hardware and / or software configuration of the signage content reproducing apparatus 300, which reproduces the signage content generated according to the signage content generation method, as compared to the configuration for reproducing the existing signage content. It can be simple. In addition, the resource utilization efficiency of the signage content reproducing apparatus 300, which reproduces the signage content generated according to the signage content generating method, may also be increased.

FIG. 17 illustrates a process of merging a background image and a specific image object into one image object according to the signage content generation method illustrated in FIG. 16.

Referring to FIG. 17, it can be seen that the signage content generating apparatus 100 according to the present invention may generate a new image object by merging a background image and an image object.

On the other hand, when an image object is merged with a background image, the image object is always displayed on the background image. This is because image objects constituting the signage content are generally placed on a specific background image.

However, when two image objects having different layers that do not include a background image are merged and the two image objects have an overlapping display area, an image object forming an upper layer among the two image objects is included in the overlapping display area. It is preferable that an image corresponding to is displayed.

FIG. 18 is a flowchart illustrating an example of a process of setting or resetting display attributes of first to third image objects according to the signage content generation method illustrated in FIG. 16. Hereinafter, the process will be described with reference to necessary drawings.

When the third image object is generated, the signage content generating apparatus 100 according to the present invention sets an area including display areas of the merged first and second image objects as the display area of the third image object.
