1 is a diagram illustrating a structural diagram of a user terminal performing a method for generating a slide show according to an embodiment of the present invention.

The user terminal of the present invention may identify at least one image selected by the user from among the images stored in the storage of the user terminal or stored in the database of the server.

To this end, the user terminal may receive images from the server. A slide show desired by the user may be created using the image identified by the user terminal. The user terminal may include a processor. A processor included in the user terminal may perform the method of generating a slide show of the present invention.

For example, the user terminal may be a smart phone, a tablet PC, or the like. The user may input to the user terminal by selecting at least one image to be included in the slide show from among the images displayed on the user terminal. In this case, the image displayed on the user terminal may be stored in a storage device of the user terminal or may be an image received from a database of the server.

In the present invention, a slide show may mean displaying successive images or slides sequentially according to time. In the slide show, various effects or animations may be added in displaying images. Also, audio may be inserted into the slide show.

A user may edit an image desired by the user through the user terminal of the present invention and create a slideshow in which user desired effects are added by using the edited image.

2 is a flowchart illustrating a method for generating a slide show according to an embodiment of the present invention.

In step 201, the user terminal may identify at least one or more images selected by the user from the storage device of the user terminal or the database of the server.

That is, the user may create a slide show by using an image directly acquired through the camera of the user terminal or an existing image stored in the database of the server. In this case, the server may mean a server of an application executed by the user terminal.

For example, various types of images may be stored in the database of the server. In particular, the database of the server may include images of various kinds of living things or images of domestic and foreign art works depicting diversity of living things.

In step 202, the user terminal may edit the image according to the user's editing command for at least one image.

When the user's edit command is a command for enlarging, reducing, or rotating an image, the user terminal may enlarge, reduce, or rotate the image according to the user's edit command. In addition, when the user's edit name is a command for a screen ratio, the user terminal may modify the image to match the screen ratio determined by the user.

When the user's editing command is a command for inserting text, the user terminal may add text to the image according to the user's editing command. For example, the text may be moved to a position desired by the user within the image through the user's dragging. The user terminal may display the text input by the user.

When the user's editing command is a command for editing text, the user terminal may change any one of font, style, character color, and writing effect of the text according to the user's editing command.

For example, the command for editing the text may be a command for changing the color of a text box including the text, the style of the text box, the font of the text, the size of the text, the color of the text, and the alignment of the text. The user terminal may change the text or text box according to a command for changing the color of the user's text box, the style of the text box, the font of the text, the size of the text, the color of the text, and the alignment of the text.

For example, the command for editing text may be a command for changing a radius of a character, a position of a character, a line spacing, a character spacing, transparency of a character, rotation of a character, and inversion of a character. The user terminal may change the text or text box according to commands for changing the radius of the letters, the position of the letters, the line spacing, the letter spacing, the transparency of the letters, the rotation of the letters, and the inversion of the letters.

When the user's editing command is a command for adding a sticker stored in the storage device of the user terminal or the database of the server, the user terminal may add the sticker according to the user's editing command to the image.

Here, the sticker may be another image stored in the user's terminal. In addition, it may be a basic figure (eg, a rectangle, a circle, a triangle, a heart, etc.) provided from the server's database or other images stored in the server's database. The size, position, angle, and color of the sticker may be determined by a user's manipulation.

When the user's editing command is a command to cut an image or select only a part, the user terminal may select and display only a part of the image according to the user's editing command. Also, when the user's editing command is a command for coloring an image, the user terminal may color the image according to the user's editing command.

When the user's editing command is a command for filtering, the user terminal may process the filtering on the image according to the user's editing command. In the present invention, filtering may mean various transformations of an image.

When the user's editing command is a command to change color tones such as brightness, contrast, saturation, and sharpness of an image, the user terminal may change color tones such as brightness, contrast, saturation, and sharpness of the image according to the user's editing command.

When the user's editing command is a command to perform blur processing on a part of an image, the user terminal may perform blur processing on a part of the image according to the user's editing command. For example, in the present invention, the blur may include a Gaussian blur or a motion blur for a specific area.

In step 203, the user terminal may generate a slide show using the edited image.

Among the edited images, the image stored in the user terminal and the image received from the data of the server may have a significant difference in picture quality. Even when there is no user's editing command, the user terminal may generate a slide show by processing an effect to be described later on the edited image.

In this case, when the image quality of the image received from the database of the server is higher than the image quality of the image stored in the user terminal, the user terminal reduces the image quality or applies a blur to the image received from the database of the server to include the image included in the slide show. You can adjust their quality.

In addition, when the image quality of the image received from the database of the server is lower than the image quality of the image stored in the user terminal, the user terminal reduces the image quality or applies blur to the image stored in the user terminal to improve the image quality of the images included in the slide show. Can be adjusted.

If the user sets in advance, the user terminal only adjusts the color tones such as brightness, contrast, saturation and sharpness of the selected images, such as brightness, contrast, saturation, and sharpness of the selected images, or filters the images stored in the user terminal. can be emphasized.

Also, when the ratio of the background and the object included in the image is different, a sense of heterogeneity may occur for each slide. Accordingly, the user terminal may correct the ratio of the object included in the image stored in the user terminal and the image received from the server data among the selected images.

The user terminal determines which of the edited image is the ratio of the object size to the total area of the image specified by the user, the ratio of the object size to the total area in one of the edited images, and the average ratio of the object size to the total area of the edited images. You can modify the proportions of the edited image according to one.

For example, if the user determines a ratio such that the size of the object occupies 30%-40% of the total area, the user terminal determines the size of the object included in the edited images from 30%-40% of the total area of each image. You can enlarge or reduce the size of the object in each image to occupy a %.

The user terminal may set a time interval between slides of the slide show according to the total playback time of the slide show and the number of edited images specified by the user. For example, when the total time is set to 10 seconds and the number of edited images is 10, the edited images in the slide show are switched once per second. That is, the total playback time of the slide show designated by the user may correspond to the sum of the time intervals of each image.

The user terminal may set the time interval of the edited images according to a user's command. When the user selects specific images from among the edited images, the user terminal may set the time interval of the selected specific images to be longer than the time interval of other images.

For example, the user terminal may set the time interval between images stored in the user terminal in the slide show longer than the time interval of images selected from the database of the server.

The user terminal may add the audio data selected by the user to the slide show. The added audio data is played together when the slide show is played. Here, the audio data may include a music file.

When the user terminal creates a slide show through the edited images, various animation effects may be added according to the user's selection in displaying the images. For example, when an image is switched in a slide show, a motion of an object included in the image moving in a specific direction may be added.

For example, the user terminal may add a specific animation effect only when images stored in the user terminal among the edited images are displayed in a slide show.

For example, the edited images may include objects such as animals or insects. In generating the slide show, the user terminal may add a specific animation effect only when an object included in the edited image changes. In addition, the user terminal may add a specific animation effect only when a specific object preset by the user appears.

The user terminal may extract an object included in the edited image. When the user terminal creates a slide show using data on the motion of the same object included in the edited image in the database of the server, an animation effect in which the object moves may be added.

As an example, the user terminal may add the moving animation of the object through augmented reality to the slide show based on the object and data obtained from the database of the server.

For example, when an object such as a frog is included in the edited image, the user terminal extracts the shape of the object from the edited image, and uses the shape of the object extracted from the database of the server to obtain data on the movement of the object. can be obtained Then, the user terminal may add an animation of the object moving when the object of the edited image appears in the slide show based on the acquired data.

As another example, the user terminal may extract an object from the edited image and obtain information about the object by using the shape of the object in the database of the server. When the user terminal displays the slide show, information on the object may be displayed on a part of the screen.

For example, when a frog is included in the edited image, the user terminal may extract the shape of the frog from the edited image, and obtain information about the frog using the shape of the frog extracted from the database of the server.

Then, when the frog is displayed in the slide show, the user terminal may provide information about the frog (eg, life span, food, type, etc.) in the form of a hyperlink or text to a part of the screen. In this case, the user terminal may extract and recognize the object from the image by using a technique such as a neural network, deep learning, or machine learning.

In the present invention, the user terminal may arrange the edited images according to the order specified by the user and generate a slide show suitable for the total playback time specified by the user. The slide show may proceed according to a user's input or may be performed without a user's input.
