Description

Presentation document editing device capable of efficiently updating thumbnail images and its operation method {PRESENTATION DOCUMENT EDITING APPARATUS CAPABLE OF EFFICIENTLY UPDATING THUMBNAIL IMAGES AND OPERATING METHOD THEREOF}

The present invention relates to a technique for efficiently performing update processing of a thumbnail image of a presentation document.

Recently, as computers, smartphones, tablet PCs, and the like are widely used, various kinds of electronic document-related programs for reading, creating, and editing electronic documents using such terminal devices have been released.

These electronic document related programs include word processors that support the creation and editing of basic documents, data entry, arithmetic operations, spreadsheets to assist with data management, and presentation programs to assist presenters.

Among the above-mentioned electronic document related programs, the presentation program is a program that assists the terminal device to create a presentation document suitable for use by the user. The user can insert various objects such as shapes and tables on the presentation document. It provides a function to enable it.

Usually, when a presentation document is loaded in the terminal, the presentation document is displayed on the screen as shown in FIG. That is, the screen on which the presentation document is displayed is divided into a body display area 210 and a thumbnail image display area 220 as shown in FIG. 2, and the present text selected by the user is displayed in the body display area 210. The body of the slide page is displayed, and the thumbnail image display area 220 displays thumbnail images 230 of the plurality of slide pages constituting the presentation document.

In this case, when the user selects a thumbnail image of a specific slide page among the thumbnail images 230 of the plurality of slide pages displayed in the thumbnail image display area 220, the body page displays the slide page selected by the user. Will be displayed. This allows the user to quickly move to the desired slide page simply by selecting the thumbnail image.

In general, when thumbnail images 230 displayed on the thumbnail image display area 220 are changed in the corresponding slide page due to the user action associated with document editing being applied, each thumbnail is displayed in response to the change of the slide page. The image is also updated.

However, in the technique of updating the thumbnail image of the existing presentation document editing technology, a single thread is used for editing the presentation document without the scheduling of user action and update of the thumbnail image. There was a problem that the efficiency of thumbnail image update operation is reduced in that it was randomly processed.

For example, when a change occurs in a slide page as a user action for editing is applied to a specific slide page from a user, the existing presentation document editing technology changes the slide page regardless of whether additional user actions are authorized from the user. Since the update processing of the thumbnail image is performed for the user, even if the user grants an additional user action for editing the document, the additional user action may not be reflected in the presentation document until the update processing of the thumbnail image is completed. .

In general, in creating a presentation document, a user often authorizes a user action for editing a document several times in succession rather than only once. As a result, even if the user has not completed the approval of a series of user actions on the presentation document, if the user cannot approve the continuous user actions due to the update processing of the thumbnail image, the flow of creating the presentation document is increased. This break may cause inconvenience to the user.

In particular, recently, a document collaboration system has been introduced to allow multiple users to co-edit a presentation document. In this document collaboration system, a presentation document is provided because a plurality of users authorize user actions on the presentation document. If a particular user has a difficulty in approving a user action due to the update processing on the thumbnail image of the document, efficient document collaboration may be difficult.

Therefore, there is a need for a technique for supporting a thumbnail image of a presentation document that can be efficiently updated without interrupting the processing of a series of user actions authorized by a user in relation to the presentation document editing technique.

The present invention enables an efficient updating of a thumbnail image for a presentation document without interrupting the processing of a series of user actions applied by the user, thereby allowing a user to edit a presentation document. SUMMARY An apparatus for editing a presentation document capable of efficiently updating an image and a method of operating the same are provided.

As shown in FIG. 2, when the presentation document is loaded, the display area separator 112 may divide the screen into a body display area 210 and a thumbnail image display area 220, and the slide display unit 113 may include a text. A first slide page, which is any page selected by the user among the plurality of slide pages, is displayed on the display area 210, and the plurality of thumbnail images 230 are displayed on the thumbnail image display area 220. I can display it.

The update target storage unit 114 updates the thumbnail image with identification information on the changed slide page whenever a change occurs in the plurality of slide pages due to a user action for editing the presentation document from the user. The identification information of the target slide page is sequentially stored in the memory.

Here, the user action refers to an action for instructing execution of a command for editing the presentation document, such as inserting or modifying text, a figure, an image, or the like into the presentation document. When a change occurs in the plurality of slide pages as an action is applied, whenever the change occurs, identification information about the changed slide page may be sequentially stored in the memory. In addition, the identification information for the slide page means information for identifying each slide page, and the page number assigned to each slide page may correspond to this.

For example, when the slide page 1, the slide page 2, and the slide page 3 are sequentially changed due to the user action being applied, the update target storage unit 114 identifies the identification information of each of the slide page 1, the slide page 2, and the slide page 3. May be sequentially stored on the memory.

The event generator 115 checks whether the user enters an idle state in which the user action is no longer authorized by the user, and when it is determined that the user enters the idle state, generates an thumbnail update event.

In this case, according to an embodiment of the present invention, the event generator 115 may include a first update target confirmation unit 117 and an idle state confirmation unit 118.

Whenever a user action is applied from the user, the first update target checking unit 117 checks whether identification information of the slide page to be updated is stored in the memory.

When it is determined that one or more pieces of identification information of a slide page to be updated are stored in the memory, the idle state checking unit 118 is within a predetermined first delay time from the time when the last user action is applied. If it is determined whether the user action is additionally received and it is determined that the user action is not further received within the predetermined first delay time, it is determined that the user action has been entered and the occurrence of the thumbnail update event is processed.

For example, when the user actions 1 and 2 are authorized by the user, the first update target checking unit 117 may display the identification information of the slide page to be updated on the memory whenever the user actions 1 and 2 are applied. You can check whether it is stored.

When the user action 2 is authorized, if it is confirmed that the identification information of the slide page is stored in the memory, the idle state checking unit 118 determines the predetermined first delay time from the time when the user action 2 is applied. It is possible to check whether additional user actions are received within a predetermined time period, and if additional user actions are not received from the user until the predetermined first delay time passes, it is determined that the user enters an idle state to generate the thumbnail update event. have.

When the thumbnail update event is generated, the thumbnail image updater 116 extracts identification information of the second slide page stored at the highest point of the identification information of the slide page stored on the memory and the second slide. The thumbnail image for the second slide page is regenerated based on the identification information for the page, and the thumbnail image for the second slide page being displayed on the thumbnail image display area is reproduced for the second slide page.

Extract identification information about the stored second slide page.

When the thumbnail regeneration unit 121 extracts the identification information of the second slide page, the thumbnail regeneration unit 121 regenerates a thumbnail image of the second slide page of the plurality of slide pages based on the identification information of the second slide page. do.

The thumbnail image change processing unit 122 changes the thumbnail image for the second slide page displayed on the thumbnail image display area into a thumbnail image regenerated for the second slide page.

For example, when the identification information of the slide page 1 and the slide page 2 are sequentially stored in the memory, and if the thumbnail update event occurs, the second update target confirmation unit 119 displays the slide page on the memory. You can check again whether the identification information is stored.

Since it is assumed that identification information for slide page 1 and slide page 2 are sequentially stored in the memory, the identification information extracting unit 120 identifies identification information for slide page 1 and slide page 2 stored in the memory. Among them, identification information about slide page 1 stored at the best point may be extracted.

Then, the thumbnail regeneration unit 121 may regenerate a thumbnail image of the slide page 1 of the plurality of slide pages constituting the presentation document based on the identification information of the slide page 1, and the thumbnail image change processing unit 122 changes the thumbnail image for the slide page 1 displayed on the thumbnail image display area into a thumbnail image regenerated for the slide page 1, thereby completing the update processing of the thumbnail image for the slide page 1; can do.

Can raise an event

That is, if no user action is additionally received within the predetermined second delay time from the time when the processing of changing the thumbnail image for the second slide page is completed through the thumbnail image change processing unit 122, the idle state is maintained. As can be seen, the redo control processor 124 may generate the redo event for the redo of the update process of the thumbnail image, so that the second update target confirmation unit 119 is in the memory. If the identification information of the slide page to be updated is stored in the identification information extraction unit 120, the identification information of the slide page of the best view from the memory, if the identification information of the slide page is stored in the memory The thumbnail regeneration unit 121 may extract identification information about the extracted slide page. The thumbnail image can be reproduced on the basis of the image, and the thumbnail image change processing unit 122 performs image change processing based on the regenerated thumbnail image on the thumbnail image display area, thereby continuously performing an update processing operation of the thumbnail image. can do.

However, if the user action is additionally received within the predetermined second delay time from the time when the processing of changing the thumbnail image for the second slide page is completed through the thumbnail image change processing unit 122, the idle state is considered to have ended. As such, the redo control processor 124 may generate an update processing stop event for controlling the update processing of the thumbnail image not to be performed until the thumbnail update event occurs again through the event generator 115. . Thereafter, if the thumbnail update event occurs again through the event generator 115, the thumbnail image updater 116 may perform an update process on the thumbnail image.

The presentation document editing apparatus 110 capable of efficiently updating the thumbnail image according to the present invention described above operates to perform the update process of the thumbnail image when the user action is not in an idle state. However, if a user action is continuously received by the user, since there is no room for idle state, the thumbnail image updating process is not performed, and only identification information of the slide page to be updated can be accumulated in the memory. According to another exemplary embodiment of the present invention, the presentation document editing apparatus 110 capable of efficiently updating the thumbnail image has elapsed from the time when the last update of the thumbnail image has been selected through the event generator 115. In this case, the thumbnail image update event may be generated so that the thumbnail image update process may be performed even if the image is not idle, so that the thumbnail image update process may be performed.
