Preferred embodiment of the invention

In the related art, a slide application that is more common on a terminal is to display a picture that has already been taken, a slide show with a certain frame rate and different animation effects, and can add background music. However, this method often has two shortcomings. First, the user can only preview all the photos taken, can not customize the selected photos, and can not automatically match the photos according to the photo attributes to automatically select; second, the user I can't control the number of slides and the fit of the music. Sometimes the background music hasn't finished, but the photos have already finished playing. Sometimes there are a lot of slides that haven't finished, but the music is too short.

In order to solve the above problem, an embodiment of the present invention provides a method and apparatus for generating a slideshow on a mobile terminal, so that a user can arbitrarily select a photo while providing an intelligent matching function, that is, automatically matching according to the attribute of the photo selected by the terminal. Automatically selecting photos with the same attributes also improves the user experience.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

First, the first embodiment of the present invention will be described with reference to the accompanying drawings.

The embodiment of the invention provides a slideshow production system. The structure of the system is as shown in FIG. 1 and includes:

Photo selection module 101, the module includes a counter and provides intelligent selection function;

Music selection module 102;

Slideshow production module 103.

The above module constitutes the entire slide production system, and the scheme is described below.

After the user takes a photo, the user can customize the selected photo, and can use the smart matching function to automatically match the photo according to the specific attribute of the selected photo; the customized audio file can be loaded as the playing background, and the music can be selected according to the selected music. The duration and the number of sheets of the selected photo are used to calculate the playback rate, which is the perfect match between the length of the music playback and the length of the slideshow.

After the user takes a photo, start making a slideshow. The terminal can enter the saved photo path from the file manager's entrance when making the slide show. Each time a photo is selected, the counter is incremented by one until the selected photo ends, and the counter accumulates the number of selected photos and sends the slide to the slide. Making a module, the above is the process of manually selecting a photo.

If the user opens the smart selection function before selecting the photo, the system provides two ways of intelligent selection, one is according to the picture taking time, and the other is according to the picture taking place. If the former is selected, after the user selects the first photo, the system automatically extracts the time information in the file attribute, and then automatically searches for the file with the same attribute in the current path, and each time a photo with the same attribute is searched, The system will automatically select and increment the counter until all searches are completed and the final result is sent to the slideshow production module. If you choose to follow the photo location of the picture to intelligently select, because the location attribute needs to open the GPS function before taking pictures, not all photos have this attribute, so the system will extract the file attribute of the first photo to see if there is location information, if The next selection is not performed in sequence, but the photo information selected by the user is also saved effectively, and the counter is also accumulated and sent to the slideshow production module until the first photo of the location attribute appears, and the location is The information is saved and then searched for photos with the same location attribute. Each time one is searched, it is automatically selected, and the counter is incremented by one until the search is completed, and the finally selected photo information and the accumulated number of sheets are sent to the slideshow making module.

After the photo selection is completed, the terminal enters the path of the audio file storage of the file manager to select background music, and the terminal extracts the duration information of the audio file storage, and then stores the information and sends it to the slideshow production module; the slideshow production module According to the number of photos in the counter and the length of the music obtained, the rate of playing the slideshow is calculated as a function, which maximizes the effect of the length of the music and the length of the slideshow.

The first is the photo selection module 101 of the terminal. If the user does not open the smart selection function, the terminal performs manual selection: the system enters the path of the file manager to save the image, and the user selects a valid selection operation, and the counter of the photo selection module is added. First, when the photo selection is completed, The terminal will receive a system trigger signal. At this time, the counter is accumulated and the final accumulated result is saved and sent to the slideshow production module, and the counter is cleared. If the user turns on the smart selection function, the user can select to automatically select according to the photographing time or Automatically select according to the location of the photo. Select to automatically select according to the time of the photo, the terminal will automatically extract the time attribute of the file when the first photo is selected, and then automatically search for the file with the same attribute, the file attribute to be extracted is saved, and then all other file attributes are saved. This byte is compared. If they are the same, the time is the same. The system automatically selects the photo. Each time a valid selection is made, the system will send the photo information to the slideshow production module, and the counter will be incremented until all the photos are automatically selected. At the end, this process is consistent with manual selection. If you choose to automatically select the location according to the location, the terminal will extract the location attribute of the first photo selected. If there is no such property, the photo has no matching features, but it is also a valid selection. The photo will be sent to the slideshow. Make a module and increment the counter to continue selecting the next photo until the first photo with the location attribute appears. At this point, the terminal will extract the location information and automatically search for files with the same attributes. For each search, The photo is tagged and sent to the slideshow production module, and the counter is incremented by one until the search match is completed and the counter is cleared.

After the photo selection is finished, the system enters the music selection module 102, and the module enters the file manager to find the storage path of the audio file. After the user effectively selects the audio file, the music selection module extracts the duration information of the audio file, and This information is sent to the slideshow creation module 103; after the selection of the picture and music is completed, the system proceeds to the slideshow creation module 103. The slideshow making module 103 calculates a matching play rate by a function according to the received photo number information and the music duration information. If the selected audio file is too short, the calculated play rate is less than a specific value (this value The user can set in advance, if it is not set, it is the default minimum experience value of the system), then the user is prompted that the music is too short, and the music needs to be selected again. At this time, the music selection module 102 is entered again, and the user can re-select an audio file with a longer duration. It is also possible to select one audio file and the previous audio file to play in sequence. If the latter is selected, the slideshow creation module 103 needs to accumulate the first acquired music duration and the second acquired music duration to calculate the playback speed. . After the playback speed is set, the user can select the playback effect. After the above settings are completed, the system will play the selected photos at a certain playback speed with the set music background. At this time, the entire slide is completed.

As shown in FIG. 2, the flowchart of the smart selection of the photo selection module 101 is used to obtain the photo information selected by the terminal and accumulate the number of sheets. The user first chooses to automatically select by time or automatically according to location. If the selection is automatically selected according to time, the first photo is manually selected first, and the terminal tags the information of the photo and counts it, sends it to the slideshow creation module 103, and extracts the time attribute of the file and saves it. Then search all the pictures in sequence, compare the saved time attribute with the same byte of each picture file. If the comparison result is the same, the photo will be automatically selected, and the photo will be tagged and sent to the 103 module, the counter plus One. Repeat the above process until all image searches are completed. After the completion, the system will receive a trigger message. At this time, all files with the same time attribute are automatically selected and the counter is cleared. If the latter is selected, that is, the picture is automatically selected according to the location information, the first photo is manually selected first, and the terminal tags the information of the photo and counts it, and sends it to the slideshow making module 103, and determines whether the file can be extracted. Location information (whether the file contains location information depends on whether the GPS function is turned on when the photo is taken). If it is not extracted, the photo is also a valid selection. According to the process, the information is sent to the C module, and the counter is incremented by one. Select the photo, repeat the above process until the first photo with the location attribute appears, extract the information and save it, search all the images in sequence, compare whether the same byte is consistent, if it is consistent, select it automatically until all the images are compared. All photos with the same location attribute are selected and the counter result is sent to C and cleared.

FIG. 3 is a flow chart of manual selection of the photo selection module 101. The terminal first searches for the image save path through the path of the file manager, and then manually selects the photo, and sends each selected photo to the C module, and the counter adds one after each successful acquisition of the photo of the selected photo. Until the end of the selection, the result is also sent to the slideshow creation module 103 that creates the slideshow, and the slideshow creation module 103 saves the information and clears the counter.

4 is a flow chart of the audio file selection module 102 selecting an audio file in the embodiment of the present invention.

The terminal first searches through the path of the file manager to the storage path of the audio file, and then selects the audio file. After receiving the message of the valid selected file, the terminal sends the file to the slideshow creation module 103, and the time length information of the extracted file is simultaneously sent to the slideshow creation module 103, and the slideshow creation module 103 saves the information after receiving the information.

FIG. 5 is a flow chart of the final slide show module 103 generating a slide show. First select the photo The information acquired by the module 101 and the audio file selection module 102 are extracted separately, and the appropriate playback speed is calculated in the following function calculation manner.

Function one: play speed = music duration (s) / number of photos (张)

The terminal allows the user to set the minimum value of the playback speed in advance. If the user does not set it, the default experience value is used. If the calculated playback speed is less than the minimum value, the system prompts the user to select the music background file again, and can re-select the last selected file again, or on the basis of the last file, re-select and re-enter B. The flow of the module. If the user selects the latter, the system will play the selected files in sequence, and the duration will be accumulated, and the playback speed will be calculated again by the function one above.

The photo information determined by the photo selection module 101, the audio file information determined by the audio file selection module 102, and the entire processing flow of the slide creation module 103 constitute the entire slide production system, and are selected according to the calculated playback speed. The fixed audio file is used as the background to play the selected files in sequence until the photo and music playback ends.
