FIG. 1 is a block diagram of an image filter processing application according to an embodiment of the present invention, and FIG. 2 is a conceptual diagram of an image filter processing application according to an embodiment of the present invention.

1, an image filter processing application according to an embodiment of the present invention includes an image list providing unit 110, an image loading unit 120, an image converting unit 130, an image filter storing unit 140, A graphical user interface (GUI) providing unit 160, and a server interworking unit 170. Here, the above constituent parts are merely logically distinguished according to functions and roles possessed by the respective constituent parts, and can also be constituted by software codes.

An image filter processing application according to an embodiment of the present invention may be installed and executed in a user's electronic device (e.g., smart phone, tablet PC, notebook, desktop PC, etc.).

2, according to the execution of the image filter processing application according to the embodiment of the present invention, a gallery-type image list is displayed on a specific area of the display screen 10 (i.e., an app screen) (Hereinafter referred to as a filter list display area 30) that is different from the image list display area 20 (hereinafter referred to as a filter list display area 20) Lt; / RTI > The configuration of such an application screen is performed by the GUI providing unit 160 according to a pre-designed application realization method. In the present specification, an image is used as a concept including a moving picture as well as a still image or picture such as a photograph.

The image list to be displayed in the image list display area 20 is provided by the image list providing unit 110. [ The image list provided by the image list providing unit 110 may be a list of images stored in the user terminal in which the application is installed, but the user terminal may be connected to an external server including a communication module In this case, an image list may be provided from an external server. At this time, the external server may be a specific application server providing a photo sharing service, or an application server providing a social network service. Of course, it is obvious that a server that stores images such as photos can be an external server without any limitation.

The image list provided by the image list providing unit 110 is displayed through the image list displaying area 20 by a predetermined number. 2, it is assumed that a total of six images are displayed in the image list display area 20. However, the number of images to be displayed in the image list display area 20 can be variously modified according to an application implementation method Of course. The image list can be displayed on the screen in the form of a gallery by a thumbnail image generally as illustrated in FIG. Of course, it is obvious that a different type of screen display is possible.

In the filter list display area 30, image filters of a specific filter effect applicable to each of the images in the image list are displayed. At this time, the display method can be modified in various ways. In the example of FIG. 2, a case is shown in which a sample in which the filter effect by each image filter is visually distinguished (identified) is displayed on the screen in the form of a thumbnail image. The number of image filters to be displayed on one screen can be set in advance through the filter list display area 30. If it is difficult to display all the image filters through one screen, It is possible to update and display the filters guided through the list display area 30. At this time, the image filter list displayed in the filter list display area 30 is generally a list of filters stored in the image filter storage unit 140, but it may be a filter list downloaded from the external server described above.

2, the image filter display area 30 is separately arranged on the application screen. However, the method of guiding the image filter list in the form of a text menu according to the user's selection without arranging the filter list display area 30 Applicable. Hereinafter, for convenience and concentration of explanation, description will be made on the basis of a screen example of Fig. 2.

 The image conversion unit 130 performs an image conversion process based on the filter effect corresponding to the selection of the specific image filter by the user. The server interworking unit 170 is responsible for interlocking processes such as receiving an image list from an external server or receiving filter information, and registering images to an external server through a communication connection with an external server do. The functions and roles of the respective components are controlled through the controller 150.

Hereinafter, with reference to the flow chart of FIG. 3 and the flowchart of FIG. 7, an image filter processing process according to the application will be described in detail with reference to the components and overall concept of the image filter processing application according to the embodiment of the present invention. . In the description process, the screen examples and application examples of Figs. 4 to 6 and Figs. 8 to 11 will be referred to together.

 3 is a simplified flowchart of an image filter processing application in accordance with an embodiment of the present invention.

Referring to step S110, if a user selects a selection regarding a collective image folder such as a photo gallery (in this case, corresponding to a request for loading an image of a thumbnail image regarding the photos in the gallery) The studying unit 110 provides a list of corresponding thumbnail images, so that the GUI providing unit 160 displays a list of the provided thumbnail images in the image listing display area 20 as much as the number of displayable thumbnail images. At this time, the GUI providing unit 160 may display (or guide) the list of image filters applicable to the respective images in the displayed image list together through the filter list display area 30. That is, the step S110 corresponds to the screen configuration shown in Fig. 2 or the screen configuration shown in Fig. 8 (b) in the picture gallery shown in Fig. 8 (a).

Referring to step S120, when a specific image filter is selected from the screen-displayed image filter list, the image converting unit 130 converts all or part of the image in the image list display area 20 into a corresponding filter effect And performs an image conversion process. Accordingly, in step S130, the converted image to which the specific filter is applied is reflected on the image list and is displayed (i.e., updated display) in the image list display area 30. An example of this is shown in Fig. 4 (a).

4A shows a case where, when the "Black & White" (i.e., the image conversion process to the gray scale image) is selected as the filter effect in the state shown in the screen example of FIG. 2, All six photographic images displayed are filtered. As described above, according to the embodiment of the present invention, when a specific filter in the filter list display area 30 is selected, all the photo images displayed in the image list display area 20 are collectively displayed in accordance with the filter Can be converted.

9 (a) shows a case where the filter effect is applied to all the photographs in a specific photo gallery by selecting the "M-BlueM" filter, and FIG. 9 (b) A filter is selected so that the filter effect is applied to all the pictures in a specific photo gallery.

At this time, the application of the filter effect can be performed only on the images displayed on the current screen. That is, other photo images in the gallery that are not displayed on the current screen may be applied in real time when the future photo images are displayed on the app screen. For example, through the operation of scrolling down the image listing display area 20, a filter effect can be applied in real time when other photographic images in the gallery are displayed on the app screen. In order to display the image in the image list display area 20, a track bar or a scroll bar for displaying the top, bottom, left, and right sides of the screen may be displayed in the image list display area 20 There will be. In accordance with the manipulated degree according to the up, down, left, and right scroll operations, at least one of the strength, saturation, brightness, and contrast of the applied filter can be updated for all thumbnail images of the thumbnail image list displayed on the screen.

Although the case where the filter effect is applied to all the photographic images displayed in the image list display area 20 is exemplified above, it is needless to say that various modifications may be made in accordance with the implementation method of the app.

That is, according to another embodiment, only some photographic images selected by the user may be implemented so that the filter effect by the specific filter is applied. For example, only the photograph image directly selected by the user through the check box 28 as shown in FIG. 4 (b) may be subjected to image conversion at a time. That is, a method in which a check box or a selection button is displayed on each image in the displayed image list, and a filter effect is applied to the selected images in a lump by selecting the check box or a selection button (or, conversely, A method of applying a filter effect may be used).

As an example similar to the above, FIG. 10A also shows an example in which a specific filter is applied only to the photographic image selected through the check box 28 in the photographic gallery. 10B shows a state in which a specific filter is applied to a photo image selected by the user (i.e., a state shown in FIG. 10A). When the user selects another filter again, This is an example of applying a reselected filter to all remaining photo images.

In another related and related manner, when the user's electronic device is equipped with a touch screen, a plurality of images are selected through a specific touch selection action (e.g., double touch, long touch, etc.) There is also a way to do it. Another example of application of the filter effect through the touch selection may be the touch & drag scheme shown in Fig. Referring to FIG. 6, when the specific filter is applied to only a specific image (refer to FIG. 6 (a)) by touching and dragging a specific image filter "Black & White" b).

Referring again to the case of FIG. 4 (a), a "save button" 22, a "registration button" 24, and a "restore button" 26 are illustrated at the bottom of the application screen. Here, the save button 22 may be used to store the filtered image, the register button 24 may be used to register with an external server for the filtered image, and the restore button 26 may be used to store the filtered image It can be used to restore the original image again. Examples of use of the storage button 22, the registration button 24, and the restore button 26 will be described below as examples. It will be appreciated by those of ordinary skill in the art that the case of storage is described below as an example, but the case of registration to an external server and recovery to an original image can also be applied to the present invention. As another example, as shown in FIG. 8B, a method of restoring the original photographic image through the selection of the "Original" item in the image filter list is also possible.

 4B shows a state in which all the images in the image list are collectively "Black & White" filtered as in the screen example of FIG. 4A, Is selected. 5 (c), when the storage button 22 is pressed, only a few selected images may be finally stored with the corresponding filter effect applied, as shown in FIG. 5 (d). At this time, images other than the finally selected image may be restored to the original state before the filter effect is applied as shown in FIG. 5 (d).

In this case, the storage method of the image to which the filter effect is applied may be a method of storing the image (i.e., the changed image) subjected to the image conversion processing according to the filter effect. However, in the embodiment of the present invention, It is possible to maintain the image as it is but to associate the filter information (for example, the identification information of the image filter such as the filter name) relating to the filter effect applied to the image.

In the case where an image loading request is received again with respect to the image in which the filter information is stored in association with the filter information, the image converting unit 130 refers to the filter information and displays the converted image on the screen by applying the filter effect to the original image can do.

In addition, when registering (uploading) a corresponding filter-applied image to an external application server according to the selection of the above-described "registration button" 24, the server- Image), but the original image and the filter information applied thereto can be transmitted to the application server.

According to another embodiment, as shown in FIG. 11, it is also possible to implement a method of performing image conversion by applying all applicable filters to a specific photographic image. FIG. 11 is a view for recognizing the touch action as a command for applying all the filters in a case where any one of the photo images in the photo gallery is double-touched, .

According to another embodiment of the present invention, when outputting a photographic image to a screen, a face position of a person in the picture is analyzed, a center point of the screen is designated based on the face position, and a picture is cut out into a square A function of displaying a picture on a screen by applying a filter to the picture may be added.

In addition, by analyzing the image of a photo, it recognizes the type of the photograph and automatically selects a filter suitable for the kind of the photograph (for example, a portrait photograph, a landscape photograph, a food photograph, etc.) Can also be added.

Hereinafter, an embodiment of receiving and processing image list and / or filter information stored in an external application server through an image filter processing application according to an embodiment of the present invention will be described with reference to FIG.

7 is a simplified flow diagram of an image filter processing application in accordance with another embodiment of the present invention.

In step S210, the external application server connected to the communication receives the image list stored in the server and the filter information applied to each image in the image list.

Here, the image list to be received (to be fetched) from the external application server may be directly selected (designated) by the user, but a different method may be used. In one embodiment, when an image list download request is made while a specific filter among a plurality of image filters displayed in the filter list display area 30 is requested, only an image list to which a filter effect according to the selected image filter is applied, The manner in which it is received may be implemented.

In step S220, using the received image list, download is performed for a plurality of images from an external application server.

Accordingly, the image filter processing application can generate and display an application screen as in the screen example of FIG. 2 described above by using the image list information received from the external application server, the filter information applied thereto, and the downloaded image. At this time, as in steps S250 and S260, the image filter processing application 100 applies a filter effect corresponding to the filter information to the downloaded image based on the filter information for each image received from the external application server Real-time image conversion processing, and display it through the image list display area 20 of the app screen.

However, an image filter corresponding to the filter effect applied to the image stored in the external application server may not exist in the self storage unit (i.e., the image filter storage unit 140 in FIG. 1) according to the situation. Accordingly, in this case, the image filter processing application 100 downloads the corresponding image filter from the external application server through the server interlocking unit 160 (steps S230 and S240) Image conversion processing may be performed. At this time, the downloaded image filter may be additionally displayed in the filter list display area 30 of the app screen in the form of a thumbnail image of a sample whose filter effect by the image filter is visually identified.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims And changes may be made without departing from the spirit and scope of the invention.
