Description
Technical Field
The invention relates to the field of computers, in particular to a picture display method and device.
Background
Generally, a picture player provides a preview interface in a user interface of the picture player, so that a user can browse pictures and switch between a previous picture and a next picture according to picture preview information in a preview list displayed in the preview interface. When a user opens a picture to be watched through a picture player, the process of decoding the picture and the process of loading the picture preview information of all pictures in the directory where the picture is located into the preview list are operated concurrently through different threads, but the completion time of the two threads is difficult to be completely consistent. In order to ensure that the preview interface can be called and operated normally after the pictures are displayed, the picture player usually displays the pictures selected by the user after the preview list is generated.
Since the time required for generating the preview list is related to the number of pictures in the directory where the pictures to be viewed by the user are located, and the time required for generating the preview list is longer as the number of pictures in the directory is larger, when the number of pictures stored in the storage device is larger, after the user clicks the pictures to be viewed, the display interface of the picture player is in a loading state (i.e., a loading state) for a longer period of time, and the pictures clicked by the user and the preview list are not displayed until the preview list is generated, so that the time required for the user to wait is longer, and the user experience is poor.

Detailed Description
The method for synchronously displaying the picture preview list and the pictures provided by the embodiment of the invention is realized by a picture player, wherein the picture player refers to an application program for displaying the pictures and is installed in terminal equipment with a display function, such as an intelligent television, an intelligent mobile phone, a tablet computer or a notebook computer.
Fig. 1 exemplarily shows a user interface of a picture player, which includes a menu bar, a preview region, and a picture display region. The menu bar is used for providing a picture display function or a picture processing function for a user to select, for example, functions of picture enlargement, picture reduction, picture rotation and the like, and the functions can be provided by adopting a menu control or a control in an icon form. The preview area is used to display preview information of the picture, such as displaying a thumbnail of the picture. The picture display area is used for displaying the decoded picture.
Fig. 2 exemplarily shows a flow of a picture display method in an embodiment of the present invention, which includes the following steps:
step 201: and decoding data corresponding to the first picture based on the request for displaying the first picture, and loading picture preview information of the N pictures into a first preview list when the number of the pictures in the directory where the first picture is located is not less than a first threshold value.
The first threshold is the number of pictures corresponding to the picture preview information loaded within the decoding duration of a single picture, the size of N is equal to the first threshold, and the first preview list at least comprises the preview information of the first picture.
Specifically, when a user double-clicks a first picture in a file directory through a mouse, an operating system in the terminal device generates a request for displaying the first picture according to the user operation behavior, and sends the request to a picture player in the terminal device. In the process, if the picture player is not started, the picture player is started first. Of course, double clicking through a mouse is only an example of one user operation behavior, and the user operation behavior for triggering the display of the picture is not limited in the embodiment of the present application.
It should be noted that, in the embodiment of the present invention, the sequence of the decoding process of the first picture and the generation process of the first preview list (loading the picture preview information of the N pictures to the first preview list) is not limited. Optionally, the first thread decodes data corresponding to the first picture according to the request for displaying the first picture, and the second thread loads picture preview information of the N pictures to the first preview list when the number of pictures in the directory where the first picture is located is not less than the first threshold, where the first thread and the second thread are executed in parallel.
Specifically, the picture player acquires the encoded data of the first picture from the memory of the terminal device according to the request for displaying the first picture, and decodes the encoded data of the first picture, so that the picture player can display the first picture in the picture display area in the user interface.
Specifically, the picture preview information at least includes a thumbnail of the picture, and may further include one or more of a picture name, a picture type, a picture size, a shooting time of the picture, and a resolution of the picture. The preview list may include picture preview information for one or more pictures. The preview list may specifically be a storage area in the memory of the terminal device. And loading the picture preview information to a first preview list, namely, acquiring the picture preview information in the data corresponding to the picture to be loaded from a memory of the terminal equipment, and storing the acquired picture preview information in a corresponding storage area in a memory of the terminal equipment.
The N pictures in the first preview list may include a first picture, m pictures located before the first picture, and N pictures located after the first picture, where m + N is N-1, and m and N are integers greater than or equal to 1. If the first picture is the first picture in the file directory, the N pictures included in the first preview list include: the first picture and N-1 pictures behind the first picture. And if the first picture is the last picture in the file directory, the N pictures in the first preview list comprise the first picture and N-1 pictures before the first picture. The values of m and n can be determined according to preset values and by combining the number of pictures in the file directory and the position of the first picture in the directory.
The time length required for decoding a single picture by the picture player (i.e. the decoding time length of a single picture) may be determined by factors such as the encoding format of the picture, the decoding mode of the picture player, and the hardware configuration of the terminal device (e.g. the memory size and the processor speed). Since the decoding mode of the picture player is generally fixed, and the hardware configuration of the terminal device is also fixed, the time length required for the picture player to decode a single picture mainly depends on the coding format of the picture. In a specific embodiment, the decoding duration of a single picture of the picture player is the longest duration of time spent on decoding pictures in various encoding formats.
The time length required for the picture player to load the preview information of a single picture (the loading time length of the preview information of a single picture) is determined by the size of the preview information of a picture to be loaded. The type of the picture preview information loaded by the picture player is usually preset, so that the time length required for loading the preview information of a single picture can be obtained by pre-calculation, and therefore the time length required for loading the preview information of a single picture can be preset.
If the decoding duration of a single picture is TdPreview information of a single pictureHas a loading duration of TcIf the number of pictures corresponding to the picture preview information loaded by the picture player within the decoding duration of a single picture is equal to
In specific implementation, the picture player may pre-configure the decoding duration of a single picture and the loading duration of the preview information of the single picture to determine the first threshold, or pre-configure the number of pictures corresponding to the preview information of the pictures that are loaded within the decoding duration of the single picture.
In implementation, if the first threshold is greater than the number of pictures in the directory where the first picture is located, the picture player loads preview information of all pictures in the directory where the first picture is located into the first preview list.
Step 202: and displaying the decoded first picture and part or all of picture preview information included in the first preview list.
And when the picture player displays the decoded first picture, the displayed part of the picture preview information at least comprises preview information of the first picture.
In practice, the picture preview information that the picture player can display at a time is limited by the size of the picture player user interface and/or the screen size of the display device on which the picture player is installed. Therefore, when the number of pictures corresponding to the picture preview information included in the first preview list is small, the picture player displays all the picture preview information in the first preview list, and when the number of pictures corresponding to the picture preview information included in the first preview list is large, the picture player displays part of the picture preview information in the first preview list. For example, when the number of pictures corresponding to the picture preview information included in the first preview list is large, the picture player divides the picture preview information included in the first preview list into a plurality of pages to display, when the user clicks a function button of a previous page or a next page in a preview area of the picture player, the picture player displays the picture preview information included in the corresponding page, and for example, when the user drags a scroll bar in the preview area of the picture player, the picture player displays the remaining picture preview information in the first preview list.
In implementation, if the decoding duration of the first picture is longer than the duration required for generating the first preview list, the picture player displays the decoded first picture and the preview information in the first preview list after determining that the decoding of the first picture is finished, and if the decoding duration of the first picture is shorter than the duration required for generating the first preview list, the picture player displays the decoded first picture and the preview information in the first preview list after determining that the first preview list is generated, so that after the picture player displays the first image, the picture player can be switched to other pictures according to the operation of a user on the displayed picture preview information. And, compared with the prior art, the waiting time for the user to watch the first picture is shorter.
Optionally, if the number of pictures in the directory where the first picture is located is greater than the first threshold, the picture player may load the preview information of the other pictures in the directory except the pictures in the first preview list by, but not limited to, the following two ways after determining the number of pictures corresponding to the picture preview information included in the first preview list:
in the first mode, the picture player loads the preview information of other pictures in the catalog where the first picture is located except the pictures included in the first preview list to the second preview list.
For the first manner, in an example, when the picture player determines that the picture currently displayed in the picture display area is the last picture in the first preview list, the displayed picture preview information is updated, and the updated picture preview information includes the picture preview information in the second preview list and the picture preview information in the first preview list. For example, when the picture player is in an automatic playing mode, that is, a next picture is automatically played at intervals of a set duration according to a set sequence (for example, an arrangement sequence of pictures in a file directory), and when the last picture in the first preview list displayed in the preview area is played, the preview area is updated, so that the preview information of the pictures in the second preview list is added to the preview area. For another example, when the user double-clicks the last picture in the first preview list displayed in the preview area, the picture player may determine that the picture currently displayed in the picture display area is the last picture in the first preview list, and update the preview area, so as to add the picture preview information in the second preview list to the preview area.
In another example, the picture player receives a request for displaying a second picture, and updates the displayed picture preview information if it is determined that the second picture to be currently displayed is not in the first preview list according to the request for displaying the second picture, where the updated picture preview information includes the picture preview information in the second preview list and the picture preview information in the first preview list. For example, after the picture player displays a first picture and a first preview list, the user double-clicks a second picture in a directory where the first picture is located, the picture player receives a request for displaying the second picture, determines that the second picture to be displayed currently is not in the first preview list according to the request for displaying the second picture, and updates a preview area, so that picture preview information in the second preview list is added to the preview area, and picture preview information of all pictures in the directory where the first picture is located is displayed in the preview area.
And when the picture player determines that the picture currently displayed in the picture display area is the last picture in the first preview list or determines that the second picture to be currently displayed is not in the first preview list according to the received request for displaying the second picture, updating the displayed picture preview information, so that a user can browse the preview information of all pictures in the directory where the first picture is located, and selecting the pictures in the first preview column and the pictures in the directory where the first picture is located except the pictures in the first preview column for viewing according to the updated picture preview information.
And secondly, the picture player loads the picture preview information of the directory where the first picture is located except the pictures included in the first preview list into a plurality of third preview lists, wherein each third list comprises the preview information of a group of pictures, the number of each group of pictures is not greater than a first threshold value, and the number of the pictures included in the third preview lists is the number of the pictures included in the directory where the first picture is located except the pictures included in the first preview list.
Optionally, the loading of the picture preview information in the plurality of third preview lists may be performed concurrently in a plurality of threads, so as to reduce a time period required for loading the picture preview information in the directory where the first picture is located, except for the pictures included in the first preview list.
In order to save resources of the terminal equipment and reduce the number of threads executed in parallel in the terminal equipment, the number of pictures corresponding to the picture preview information included in each third preview list is as close as possible to the number of pictures corresponding to the picture preview information loaded by the player within the decoding duration of a single picture, so that the number of pictures corresponding to the picture preview information in at most one third preview list in a plurality of third preview lists obtained by the picture player is smaller than the number of pictures corresponding to the picture preview information loaded by the picture player within the decoding duration of a single picture, and the number of pictures corresponding to the picture preview information in other third preview lists is equal to the number of pictures corresponding to the picture preview information loaded by the picture player within the decoding duration of a single picture.
For the second mode, in an example, after the picture player loads the picture preview information of the directory where the first picture is located, except for the pictures included in the first preview list, into the plurality of third preview lists, if it is determined that the currently displayed picture is the last picture in the first preview list, the displayed picture preview information is updated, and the updated picture preview information at least includes the picture preview information in one third preview list and the picture preview information in the first preview list. For example, when the picture player is in an automatic playing mode, that is, a next picture is automatically played at intervals of a set duration according to a set sequence (for example, an arrangement sequence of pictures in a file directory), and when the last picture in a first preview list displayed in a preview area is played, the preview area is updated, so that picture preview information in a third preview including a third picture is added to the preview area, or picture preview information in a third preview including a third picture and picture preview information in a third preview including a fourth picture are added to the preview area, where the third picture is a picture next to the last picture in the first preview list in the file directory, the fourth picture is a picture next to the last picture in the third preview list including the third picture in the file directory, and the picture preview information in each third preview list is arranged in the file directory according to a picture arrangement mode corresponding to the picture preview information in the file directory (e.g., ordering by name of picture, ordering by size of picture, ordering by type of picture, etc.). For another example, when the user clicks the last picture in the first preview list displayed in the preview area, the picture player may determine that the picture currently displayed in the picture display area is the last picture in the first preview list, and update the preview area, so that the picture preview information in the third preview including the third picture is added to the preview area, or the picture preview information in the third preview including the third picture and the picture preview information in the third preview including the fourth picture are added to the preview area.
In another example, the picture player receives a request for displaying a second picture, determines that the second picture is not in the first preview list according to the request for displaying the second picture, determines a third preview list where the second picture is located according to the request for displaying the second picture, and updates the displayed picture preview information, where the updated picture preview information at least includes picture preview information in the third preview list where the second picture is located and picture preview information in the first preview list.
When the picture player determines that the picture currently displayed in the picture display area is the last picture in the first preview list or determines that the second picture to be currently displayed is not in the first preview list according to the received request for displaying the second picture, the picture player updates the displayed picture preview information, the player displays the preview information of the pictures in the first preview list and simultaneously displays the preview information of part or all of the pictures in the catalog where the first picture is positioned except the pictures in the first preview column, so that the user can browse the preview information of the pictures in the first preview list and the preview information of the pictures in the catalog in which the first picture is positioned except the pictures in the first preview list, and selecting the pictures in the first preview column and the pictures in the catalog in which the first pictures are located except the pictures in the first preview column for watching according to the updated picture preview information.
Based on the above technical solution, in the embodiment of the present invention, the picture player decodes data corresponding to the first picture based on the request for displaying the first picture, and when the number of pictures in the directory where the first picture is located is not less than the first threshold, loads the picture preview information of the N pictures into the first preview list, where the first threshold is the number of pictures corresponding to the picture preview information that is loaded within the decoding duration of a single picture, and the size of N is equal to the first threshold, so that the picture player completes the loading of the picture preview information in the first preview list as much as possible within the decoding duration of the first picture, and further the picture player can quickly display the first picture and the picture preview information in the first preview list, thereby improving the efficiency of the picture player for displaying the pictures and the picture preview information, and improving user experience.
