1 is a flowchart illustrating a method for displaying a preview image according to an embodiment. Referring to FIG. 1, an apparatus for displaying a preview image according to an embodiment (hereinafter referred to as a'display apparatus') receives at least one preview image corresponding to link information (110). The display device may be implemented by one or more software modules, one or more hardware modules, or various combinations thereof.

In one embodiment, at least one preview image corresponding to the link information may be included in metadata for preview information of a universal resource locator (URL). Here, the'metadata for preview information of URL' corresponds to an open graph tag based on the open graph protocol, which is one of the notation methods of metadata constituting the substance of the preview screen. can do. Meta data for the preview information of the URL is generated by, for example, a web browser or a web server, and the preview information of the URL is displayed through an open application program interface (API) of the display device. It may be information that is returned as requested. Meta data about the preview information of the URL may include, for example, a preview image such as an image representing the URL in addition to text such as a title and a description indicating the URL. At this time, the preview image corresponding to the link information may correspond to a static image or a dynamic image. Further, the number of preview images corresponding to the link information may be singular or plural. Hereinafter, the preview image may refer to at least one preview image.

The display device according to an embodiment may support, for example, an open API that exposes preview information of a URL generated by a web browser or a web server to a user. The display device may be driven by an application installed on the display device. For example, an application that displays a preview image may be installed on the display device. The application for displaying the preview image may include an application that provides a social networking service or an instant messaging service. The display device according to an embodiment includes, for example, a personal computer (PC), a netbook, a laptop, a personal digital appliance (PDA), a smart phone, a wearable device, and various user display devices performing similar functions. It may apply.

The display device determines a dynamic effect to be added to the preview image (120). In one embodiment, the dynamic effect to be added to the preview image is, for example, an effect of dynamically scaling the preview image within the feed region, and an effect of dynamically transitioning the preview image within the feed region. , The effect of dynamically rotating the preview image within the feed area, the effect of dynamically changing the color property of the preview image within the feed area, and dynamically giving the preview image within the feed area And a special effect, and an effect of dynamically sliding a preview image in the feed area. At this time, the feed area on the screen of the display device may correspond to a certain size and/or a certain location. The size and position of the feed area can be preset. The dynamic effect to be added to the preview image will be described in detail with reference to FIG. 2 below.

In step 120, the display device may acquire characteristics of the preview image and determine a dynamic effect based on the acquired characteristics. The characteristics of the preview image may include characteristics (eg, the number of at least one preview image, etc.) associated with the set of at least one preview image received in step 110. Alternatively, the characteristics of the preview image may include characteristics related to individual preview images (eg, the number of preview images, the resolution of the preview images, the color properties of the preview images, or various combinations thereof). have. The characteristics of the preview image are: whether the preview image is a dynamic image, the size of the preview image (or whether the preview image is a panoramic image), whether the preview image includes a location tag, and whether the preview image is an object (eg For example, it may include whether or not a person, animal, object, etc.) is included.

A method of determining a dynamic effect based on the number of at least one preview image by the display device according to an embodiment will be described in detail with reference to FIG. 3 below.

The dynamic effect may be determined for each preview image based on the characteristics of the preview image, or may be integrally determined for all of the at least one preview image. For example, when the number of preview images is plural, the display device may determine to add a dynamic effect only to some of the preview images among the plurality of preview images, and may apply dynamic effects to all of the plurality of preview images. You may decide to add.

The display device displays a preview image based on the dynamic effect (130 ). At this time, the preview image displayed based on the dynamic effect is an image to which the dynamic effect determined in step 120 is added and may correspond to a dynamic image, not a static image.

For example, the display device may generate a new image by adding a dynamic effect to the preview image, and then display the generated image. As another example, instead of generating a new image, the display device may control the output image to be displayed by adding a dynamic effect to the preview image.

A method of displaying the preview image by the display device will be described in detail with reference to FIG. 4 below.

In one embodiment, by adding various dynamic effects to the preview image corresponding to the static data or by adding additional dynamic effects to the preview image corresponding to the dynamic data, a fun factor is given to the preview image, and the dynamic preview image is added. By providing the user's interest and interest.

2 is a diagram for describing a dynamic effect added to a preview image according to an embodiment. Referring to FIG. 2, screens showing various dynamic effects added to a preview image in a feed area are illustrated.

2(a) is a screen showing an example of an effect of dynamically scaling a preview image. The effect of dynamically scaling corresponds to an effect in which the size of an object seen in the feed area increases (enlarge) or decreases (reduces) as time passes. For example, when a puppy is included in the preview image, the size of the puppy displayed in the feed area may gradually increase or decrease due to a dynamically scaling effect.

At this time, the size of the feed area does not change, and an image displayed in the feed area may be zoomed in or out. While the area of the preview image displayed in the feed area is reduced by the zoom-in effect, objects included in the preview image may be largely displayed. Also, the area of the preview image displayed in the feed area is relatively increased due to the zoom-out effect, while objects included in the preview image may be displayed in a small size.

The zoomed-in area or the zoomed-out area of the preview image may be determined, for example, by a cropping window cropping at least a portion of the preview image. The cropping window will be described in detail with reference to FIG. 4 below.

2(b) is a screen showing an example of an effect of dynamically transitioning a preview image. The transition effect may correspond to the effect of moving the position of the region in the preview image shown in the feed region. For example, suppose that the cropping window has a size corresponding to at least a portion of the preview image. In this case, the preview image may be gradually moved and viewed in a preset feed area according to a location where the cropping window moves in the preview image. According to an embodiment, the cropping window may be moved automatically or manually by a user input.

2(c) is a screen showing an example of an effect of dynamically rotating a preview image. The rotation effect may correspond to an effect in which the preview image viewed in the preset feed area gradually rotates over time.

2(d) is a screen illustrating an example of an effect of dynamically changing a color attribute of a preview image. Color properties may include, for example, color, brightness, and saturation. Brightness and saturation can be further subdivided, for example, tint, shade, tone, and the like.

The color is also referred to as a'hue', and represents pure colors (primary colors), such as yellow, green, and red. When the color tone is measured in degrees, it can be expressed from 0 to 359 degrees. Brightness represents the light and dark degree of color. Saturation represents the sharpness of a color. Saturation is also referred to as'saturation', which indicates the richness and lightness of color.

Tint corresponds to the result of mixing white with pure color. Shades are shaded, and correspond to the mixing result of adding black to pure colors. The tone represents the result of a mixture of pure colors and grayscale colors.

The effect of dynamically changing the color properties of the preview image can be, for example, gradually changing the color of the preview image from color to black and white, or from black and white to color, or the tone, tint, or color of the preview image. It may include an effect of gradually changing the shade and the like.

For example, if the preview image is called a lion image, and the effect of dynamically changing a lion image's color property is added to the lion image, the color, tone, or shade of a portion of the lion image gradually changes, or Alternatively, the lion image in color may be gradually changed to a black and white lion image.

2(e) is a screen showing an example of a special effect dynamically applied to a preview image. The special effects may include, for example, effects such as dynamic images, patterns and sparkles, gradations, and lights expressed by overlapping on the preview image.

For example, suppose that the preview image is an image of a road. When a special effect (glitter effect) is dynamically applied to an image of the road portion, a star overlaps the sky region in the image of the road portion and may be expressed. At this time, after any one of the stars twinkles, the twinkling effect may have a dynamic movement, such as stars in different positions sequentially.

2(f) is a screen illustrating an example of an effect of dynamically sliding a preview image. The sliding effect can be added, for example, when the number of preview images is plural. The sliding effect may correspond to an effect in which a plurality of preview images are sequentially moved to the left or right at regular time intervals, thereby gradually changing the preview image shown to the user in a preset feed area of the screen.

2(f) illustrates an example in which a plurality of preview images are cyclically displayed by a slide effect, and the size of the individual preview images may be adjusted to fit the size of the feed area of the display device. In this case, a plurality of preview images may not be simultaneously displayed in the feed area. Instead, one preview image may be displayed in the feed area by a slide effect, or only a portion of the two preview images may be displayed.

Although not shown in the drawings, various dynamic effects may be added according to characteristics of the preview image. For example, when the preview image includes a location tag, information on the corresponding location may be provided as a dynamic effect on the preview image. Alternatively, when the size of the preview image is larger than the threshold size, a slide effect may be added to the preview image. Alternatively, when the size of the preview image is smaller than the threshold size, a zoom-in effect may be added to the preview image. Alternatively, when the preview image includes an object, a cropping window may be positioned around the object, or a specific effect on the object may be provided as a dynamic effect.

According to an embodiment, the display device may first display a preview image to which a dynamic effect is not added, and then add a dynamic effect to the preview image when a predetermined condition related to the preview image is satisfied.

For example, the display device may determine whether to add a dynamic effect to the preview image based on whether the preview image has approached a predetermined location on the screen. If the preview image has not approached a predetermined location on the screen, the display device may display the preview image to which no dynamic effect is added. When the preview image approaches a predetermined location on the screen, the display device may add a dynamic effect to the preview image. After the predetermined condition related to the preview image is satisfied, if the condition is not satisfied again, the display device removes the dynamic effect added to the preview image and displays a preview image to which the dynamic effect is not added. can do.

In addition to the above-described examples, conditions for adding dynamic effects may be variously set, for example, whether or not a user inputs a preview image.

FIG. 3 is a diagram for describing a method of determining an operation effect based on the number of preview images according to an embodiment. Referring to FIG. 3, screens showing dynamic effects determined based on the number of preview images are illustrated. The display device according to an embodiment may determine that the added dynamic effect varies according to the number of preview images.

3(a) shows an example of a dynamic effect determined when the number of preview images is singular. The display device according to an embodiment, for example, when the number of preview images is singular, previews a scaling effect (eg, at least one of a zoom-in effect or a zoom-out effect) on the singular preview image. You can decide to add it to the view image. When the number of preview images is singular, the display device may add an effect of gradually zooming in or out of the preview image to the preview image.

According to an embodiment, when the number of preview images is singular, the display device gradually converts the color of the preview image from color to black and white or from black and white to color, or the color, tone, or background of the preview image. You can decide to add a dynamic effect that gradually changes the tone to the preview image. Alternatively, the display device may determine to add a dynamic effect of gradually changing a color attribute of the preview image such as brightness or saturation with time to the preview image. Alternatively, the display device may determine the effect of dynamically transitioning the cropping reference point of the crop window, which crops the preview image on the screen, up, down, left, and right, as a dynamic effect.

3B shows an example of the dynamic effect determined when the number of preview images is plural. The display device according to an embodiment may determine, for example, an effect of sliding a plurality of preview images as a dynamic effect when the number of preview images is plural. When the number of preview images is plural, the display device may generate a live feed view by sliding effects such as moving the plurality of preview images to the left or right according to a preset time interval.

Depending on the embodiment, the user may directly swipe through a plurality of preview images. When a user touches a plurality of preview images for a swipe, the display device may pause or cancel the automatic slide effect added to the plurality of preview images as sensing the user's touch. For example, when pausing or canceling the dynamic effect added to a plurality of preview images, the display device slides and displays a plurality of preview images according to the speed of the user's swipe input, the direction of the swipe input, and the like. It can be done.

According to an embodiment, the display device may determine a dynamic effect based on the resolution of the preview image. For example, when the resolution of the preview image is high, even if the preview image is enlarged, the image quality of the image is not significantly damaged. Accordingly, the display device may determine to add a zoom-in effect when the resolution of the preview image is greater than or equal to a preset level.

Alternatively, the display device may determine a dynamic effect based on the color attribute of the preview image. For example, when the color of the preview image is chromatic, the display device may determine to add an effect of gradually changing the color of the preview image from chromatic to achromatic.

4 is a view for explaining a method of displaying a preview image according to an embodiment. Referring to FIG. 4, cropping windows 410, 420, 4630 and 440 cropping at least a portion of a preview image according to an embodiment are illustrated.

The display device according to an embodiment may determine which dynamic effect to add to the preview image, and dynamically set a cropping window cropping at least a portion of the preview image based on the determined dynamic effect. The display device may display at least a part of the preview image cropped by the cropping window in a preset feed area. As an example, the cropping window may crop the preview image to fit the size of the feed.

Referring to (a) of FIG. 4, according to an embodiment, by shifting the position of the crop window cropping the preview image up, down, left and right according to the cropping reference point, a transition effect is added to the preview image shown in the feed area. The operation is shown. Here, the crop reference point may correspond to, for example, a center point (or center coordinate) of the crop window. More specifically, the display device may crop the preview image to fit the feed, but move the crop reference point without fixing it. For example, the display device according to an exemplary embodiment may first see a top right corner of a preview image corresponding to a crop window 410 at a first position in a feed, and then gradually increase the crop window 420 at a second position. It is possible to give a transition effect such that the center of the corresponding preview image is visible.

Referring to (b) of FIG. 4, an operation of adding a scaling effect to a preview image shown in a feed area by changing a size of a crop window cropping a preview image according to an embodiment is illustrated. The display device according to an embodiment displays the preview image corresponding to the crop window 430 of the first size in the feed, and gradually increases the size of the second image according to an effect of dynamically scaling the preview image. A preview image corresponding to the crop window 440 may be displayed in the feed.

The first sized crop window 430 and the second sized crop window 440 may be respectively displayed in the same sized feed area. In this case, pixels in the first sized crop window 430 may be displayed larger in the feed area than pixels in the second sized crop window 440. For example, for a zoom-out effect, the first sized crop window 430 may be gradually switched to the second sized crop window 440. Alternatively, for the zoom-in effect, the second sized crop window 440 may be gradually switched to the first sized crop window 430.

Even if the preview image corresponding to the link information is singular, dynamic effects may be added through the crop window. In other words, through the dynamic control of the crop window, a single preview image corresponding to the static image can be converted into a dynamic image. By adding a dynamic effect to the preview image corresponding to the link information, it is possible to show an effect of increasing the user's interest.

Even if the number of at least one preview image corresponding to the link information is plural, dynamic effects may be added through the crop window. Further, even when at least one preview image corresponding to the link information includes the dynamic image, additional dynamic effects may be added through the crop window.

Although not illustrated, the display device according to an embodiment includes a communication unit, a processor, and a display. The display device may further include a memory. The communication unit, processor, display, and memory may be connected to each other through a communication bus. The display device may be, for example, a smart phone, a wearable device, or a user device performing the same or similar function.

The communication unit receives a preview image corresponding to the link information. The communication unit may include a communication interface for transmitting and receiving data.

The processor determines the dynamic effect to be added to the preview image. The processor may dynamically set a cropping window cropping at least a portion of the preview image based on the dynamic effect. At this time, the display may be controlled by the processor to display at least a part of the image cropped by the cropping window in a preset feed area.

The processor may acquire characteristics of the preview image and determine a dynamic effect based on the characteristics of the preview image. The display shows a preview image with dynamic effects added.
