Fig. 1 is a schematic block diagram of an example computing device 100.
As shown in FIG. 1, in a basic configuration 102, a computing device 100 typically includes a system memory 106 and one or more processors 104. A memory bus 108 may be used for communication between the processor 104 and the system memory 106.
Depending on the desired configuration, the processor 104 may be any type of processing, including but not limited to: a microprocessor (UP), a microcontroller (UC), a digital information processor (DSP), or any combination thereof. The processor 104 may include one or more levels of cache, such as a level one cache 110 and a level two cache 112, a processor core 114, and registers 116. The example processor core 114 may include an Arithmetic Logic Unit (ALU), a Floating Point Unit (FPU), a digital signal processing core (DSP core), or any combination thereof. The example memory controller 118 may be used with the processor 104, or in some implementations the memory controller 118 may be an internal part of the processor 104.
Depending on the desired configuration, system memory 106 may be any type of memory, including but not limited to: volatile memory (such as RAM), non-volatile memory (such as ROM, flash memory, etc.), or any combination thereof. System memory 106 may include an operating system 120, one or more applications 122, and program data 124. In some implementations, the application 122 can be arranged to execute instructions on an operating system with program data 124 by one or more processors 104.
Computing device 100 also includes a storage device 132, storage device 132 including removable storage 136 and non-removable storage 138.
Computing device 100 may also include a storage interface bus 134. The storage interface bus 134 enables communication from the storage devices 132 (e.g., removable storage 136 and non-removable storage 138) to the basic configuration 102 via the bus/interface controller 130. At least a portion of the operating system 120, applications 122, and data 124 may be stored on removable storage 136 and/or non-removable storage 138, and loaded into system memory 106 via storage interface bus 134 and executed by the one or more processors 104 when the computing device 100 is powered on or the applications 122 are to be executed.
Computing device 100 may also include an interface bus 140 that facilitates communication from various interface devices (e.g., output devices 142, peripheral interfaces 144, and communication devices 146) to the basic configuration 102 via the bus/interface controller 130. The example output device 142 includes a graphics processing unit 148 and an audio processing unit 150. They may be configured to facilitate communication with various external devices, such as a display or speakers, via one or more a/V ports 152. Example peripheral interfaces 144 may include a serial interface controller 154 and a parallel interface controller 156, which may be configured to facilitate communication with external devices such as input devices (e.g., keyboard, mouse, pen, voice input device, touch input device) or other peripherals (e.g., printer, scanner, etc.) via one or more I/O ports 158. An example communication device 146 may include a network controller 160, which may be arranged to facilitate communications with one or more other computing devices 162 over a network communication link via one or more communication ports 164.
A network communication link may be one example of a communication medium. Communication media may typically be embodied by computer readable instructions, data structures, program modules, and may include any information delivery media, such as carrier waves or other transport mechanisms, in a modulated data signal. A "modulated data signal" may be a signal that has one or more of its data set or its changes made in a manner that encodes information in the signal. By way of non-limiting example, communication media may include wired media such as a wired network or private-wired network, and various wireless media such as acoustic, Radio Frequency (RF), microwave, Infrared (IR), or other wireless media. The term computer readable media as used herein may include both storage media and communication media.
Computing device 100 may be implemented as a personal computer including both desktop and notebook computer configurations. Of course, computing device 100 may also be implemented as part of a small-form factor portable (or mobile) electronic device such as a cellular telephone, a digital camera, a Personal Digital Assistant (PDA), a personal media player device, a wireless web-watch device, a personal headset, an application specific device, or a hybrid device that include any of the above functions. And may even be implemented as a server, such as a file server, a database server, an application server, a WEB server, and so forth. The embodiments of the present invention are not limited thereto.
In an embodiment according to the invention, the computing device 100 is configured to perform a picture display method 200 according to the invention. Among other things, the application 122 of the computing device 100 includes a plurality of program instructions for executing the picture display method 200 according to the present invention.
Fig. 2 shows a flow diagram of a picture display method 200 according to an embodiment of the invention.
It should be noted that, in the embodiment according to the present invention, one or more applications suitable for displaying pictures reside in the computing device 100, and the applications may load the pictures stored locally in the computing device 100 for presentation, such as a photo album; the application may also request a server to obtain a network picture for presentation, such as various browsers. When the application is used for displaying the pictures, the pictures are previewed in the form of thumbnails initially, namely, the thumbnails corresponding to the multiple pictures are displayed.
As described above with reference to FIG. 1, system memory 106 and storage device 132 are included in computing device 100. System memory 106 is a storage device that is relatively fast to access and loses its stored content when the computing device is powered down, and is therefore also referred to as memory. The storage device 132 has a low access speed, but has a large capacity and is a nonvolatile storage device, i.e., data can still be retained without loss after the computing device is powered off, and therefore is also referred to as an external storage device (e.g., a hard disk, etc.) of the computing device. After the computing device 100 is powered up, the contents of the application are typically loaded from the storage device 132 into the system memory 106, and then the processor is utilized to execute the instructions of the application to complete the operation of the application. In addition, the same is true of data (e.g., pictures) in the application, and some data that needs to be retained for a long time or cached for a long time may be stored in the storage device 132. While intermediate data that is needed during application execution (data that is no longer needed at application restart) may be stored in system memory 106 to facilitate the application obtaining such intermediate data at a faster rate.
According to one embodiment, the computing device 100 is adapted to present on its screen a thumbnail corresponding to the first threshold number of pictures. Here, the present invention does not limit the specific numerical value of the first threshold, and the first threshold may be determined according to the size of the area for displaying the picture on the screen and the size of the thumbnail.
As shown in fig. 2, the method 200 begins at step S210.
In step S210, a first threshold number of pictures to be displayed is determined, and the pictures to be displayed, a total of a second threshold number of pictures before and after the pictures to be displayed are loaded to the system memory 106 of the computing device. Here, the loaded picture refers to an original-sized picture. The first threshold number of pictures to be displayed is determined, for example, when the application is started, and the first threshold number of pictures to be displayed is a picture corresponding to a first threshold number of thumbnails currently suitable for being displayed on the screen, and the first threshold number of pictures to be displayed will be displayed in a preview manner in the form of thumbnails. It should be further noted that the second threshold is greater than the first threshold, that is, the number of pictures loaded is greater than the number of pictures to be displayed when the pictures are initially loaded, and the loaded second threshold number of pictures includes not only the first threshold number of pictures to be displayed, but also a plurality of pictures before and after the first threshold number of pictures to be displayed.
In one embodiment, the first threshold is, for example, 20, and the second threshold is, for example, 50, although the invention is not limited to this particular value.
It should be noted that the computing device may display a plurality of pictures arranged based on a predetermined sequence, and the sources of the plurality of pictures are not limited in the present invention, and the pictures may be pictures stored locally in the computing device, or network pictures stored in a network server.
In one embodiment, the storage device 132 of the computing device has stored therein a plurality of original-sized pictures (hereinafter referred to simply as "original pictures"), which are arranged based on a predetermined order, and which are initially adapted to be displayed in thumbnail form on the screen of the computing device. An application in the computing device (an application adapted to display pictures) may then process the original picture by loading one or more original pictures in the storage device 132 into the system memory 106, for example, cropping the original picture to obtain a thumbnail corresponding to the original picture, so as to present a plurality of thumbnails corresponding to the plurality of original pictures on a screen of the computing device.
In one embodiment, prior to loading the original pictures, computing device 100 obtains paths for all original pictures suitable for display in an application of the computing device and stores the paths for all original pictures in system memory 106. In this way, when a picture is loaded, the corresponding original picture may be loaded to system memory 106 based on the picture path in system memory 106.
Subsequently, in step S220, the loaded second threshold number of original pictures are processed so as to generate corresponding second threshold number of thumbnails based on the second threshold number of original pictures. Here, the processing of the original picture is a process of performing cropping processing on the original picture to generate a thumbnail of a predetermined resolution. A first threshold number of thumbnails, including within the second threshold number of thumbnails, corresponding to the first threshold number of pictures to be displayed are then displayed on the screen of the computing device. It should be noted that the generated second threshold number of thumbnails are arranged in the system memory based on the arrangement order of the original pictures, and the presented first threshold number of thumbnails are also presented on the screen based on the arrangement order of the corresponding first threshold number of original pictures. That is, the arrangement order of the thumbnails and the presentation order on the screen are kept consistent with the arrangement order of the original pictures.
According to the embodiment of the present invention, after the second threshold number of original pictures are processed to generate the corresponding second threshold number of thumbnails, step S230 is further executed. In step S230, the generated second threshold number of thumbnails is stored to the storage device 132 of the computing device. Here, by loading the original picture and storing the thumbnail obtained by processing the original picture in the storage device 132 local to the computing device, when the thumbnail needs to be displayed next time, the thumbnail in the storage device 132 can be directly loaded to the system memory 106, and then the thumbnail can be displayed without loading the original picture again and processing the original picture to generate the thumbnail. Therefore, the original pictures are prevented from being loaded in batches and processed every time the thumbnails are displayed, the time for loading and processing the original pictures is saved, and the thumbnail loading and displaying efficiency is improved.
Specifically, after determining the first threshold number of pictures to be displayed in step S210, it is first determined whether the storage device 132 includes thumbnails corresponding to the pictures to be displayed, the pictures before the pictures to be displayed, and the pictures after the pictures to be displayed, and if so, the thumbnails in the storage device 132 of the second threshold number of pictures are directly loaded into the system memory 106, without loading and processing the original pictures to generate thumbnails. If not, the original picture needs to be loaded into system memory 106 and processed to generate a thumbnail.
In one embodiment, when storing the thumbnail to the storage device 132, the thumbnail is stored to the storage device by determining the MD5 Value of the picture file corresponding to the thumbnail, and then, using the MD5 Value of the picture file as a key Value and the thumbnail as a Value.
Subsequently, in step S240, in response to a switching operation of the thumbnails by the user, such as a sliding operation, a clicking operation, or the like, a new first threshold number of thumbnails to be displayed is determined based on the switching operation, and the new first threshold number of thumbnails are displayed on the screen of the computing device.
It should be noted that the system memory 106 of the computing device stores the second threshold number of pre-loaded thumbnails, and the first threshold number of thumbnails is initially displayed. When the user switches the thumbnail display, the second threshold number of thumbnails in system memory 106 may include a new first threshold number of thumbnails to be displayed, so that the new first threshold number of thumbnails may be displayed directly.
According to one embodiment, after the respective second threshold number of thumbnails are initially generated (in step S220), the current index value (i.e., the initial index value) corresponding to each thumbnail is also determined based on the arrangement order of the second threshold number of original pictures. Here, the generated arrangement order of the second threshold number of thumbnails is kept consistent with the arrangement order of the original pictures, that is, the thumbnails arranged earlier have smaller index values and thumbnails arranged later have larger index values, based on the predetermined order arrangement.
For example, in a second threshold number of thumbnails arranged based on a predetermined order, the current index value corresponding to the first thumbnail is 1, and the current index value corresponding to the last thumbnail is the second threshold. That is to say, in the initially generated thumbnails with the second threshold, the minimum current index value is 1, the maximum current index value is the second threshold, the value range of the current index value is [1, the second threshold ], and the index value is an integer. In other words, the current index values corresponding to the initially generated second threshold number of thumbnails are {1,2,3, … second threshold }, respectively.
When the first threshold number of thumbnails are displayed on the screen of the computing device, the first threshold number of thumbnails are also displayed based on the size sequence of the current index value corresponding to each thumbnail, namely, the index value corresponding to the thumbnail arranged more front is smaller, and the index value corresponding to the thumbnail arranged more back is larger.
According to one embodiment, when the new first threshold number of thumbnails displayed on the screen of the computing device includes a thumbnail with the smallest current index value, that is, the first thumbnail of the second threshold number of thumbnails initially generated and arranged based on a predetermined order has been presented on the screen, since there is no thumbnail in front of the thumbnail with the smallest index value, in this case, the corresponding original picture is loaded as needed to generate a plurality of thumbnails in front of the thumbnail with the smallest current index value.
Specifically, a second threshold number of original pictures before the original picture corresponding to the thumbnail with the minimum current index value are loaded to the system memory 106 based on the corresponding picture path in the system memory 106, and a new second threshold number of thumbnails before the thumbnail with the minimum current index value are generated based on the newly loaded second threshold number of original pictures, that is, the original pictures are cropped to generate thumbnails with a predetermined resolution. In this way, one or more thumbnails before the thumbnail with the smallest current index value can be displayed on the screen of the computing device based on the switching operation of the thumbnails by the user. It should be noted that, the newly generated second threshold number of thumbnails is also stored in the storage device, so that the thumbnails can be directly loaded from the storage device when the thumbnails are displayed next time.
In one embodiment, when the new first threshold number of thumbnails displayed on the screen of the computing device include thumbnails with the smallest current index value, a second threshold value is added to the current index value of each thumbnail, and new index values are generated, i.e., corresponding new index values are respectively generated for the initially generated second threshold number of thumbnails. It should be understood that the new index value intervals corresponding to the initially generated second threshold number of thumbnails are [1+ second threshold, second threshold x 2], that is, the new index values corresponding to the initially generated second threshold number of thumbnails are {1+ second threshold, 2+ second threshold, 3+ second threshold, … second threshold x 2}, respectively.
After generating a second threshold number of thumbnails before the thumbnail with the smallest current index value, determining the index value corresponding to each thumbnail (newly generated thumbnail) before the thumbnail with the smallest current index value. Here, the range of the index value corresponding to the newly generated thumbnail is [1, second threshold ], that is, the index values corresponding to the newly generated thumbnails of the second threshold are {1,2,3, … second threshold }, respectively.
According to one embodiment, when a new first threshold number of thumbnails displayed on a screen of a computing device includes a thumbnail with a largest current index value, that is, the last thumbnail in a second threshold number of thumbnails initially generated and arranged based on a predetermined order has been presented on the screen, since there is no thumbnail behind the thumbnail with the largest index value, in this case, the corresponding original pictures are loaded as needed to generate a plurality of thumbnails behind the thumbnail with the largest current index value.
Specifically, based on the corresponding picture path in the system memory 106, the second threshold number of original pictures after the original picture corresponding to the thumbnail with the largest current index value are loaded into the system memory 106, and based on the newly loaded second threshold number of original pictures, new second threshold number of thumbnails after the thumbnail with the largest current index value are generated, that is, the original pictures are subjected to cropping processing to generate thumbnails with a predetermined resolution. In this way, one or more thumbnails subsequent to the thumbnail with the largest current index value may be displayed on the screen of the computing device based on a user's switching operation of the thumbnails. It should be noted that the newly generated second threshold number of thumbnails is also stored in the storage device so that the thumbnails can be loaded directly from the storage device the next time they are displayed. That is, each time a thumbnail is generated, the generated thumbnail is stored in a storage device local to the computing device for the next direct load display.
In one embodiment, after generating a second threshold number of thumbnails following the thumbnail with the largest current index value, the index value corresponding to each thumbnail (newly generated thumbnail) following the thumbnail with the largest current index value is determined. Here, the range of the index values corresponding to the thumbnails subsequent to the thumbnail having the largest current index value is [1+ second threshold, second threshold x 2], that is, the index values corresponding to the newly generated second threshold thumbnails are {1+ second threshold, 2+ second threshold, 3+ second threshold, … second threshold x 2}, respectively.
In an embodiment according to the present invention, each time the second threshold number of original pictures are loaded into the system memory 106 (including the initially loaded second threshold number of original pictures and the subsequently loaded new second threshold number of original pictures), a previous part of the second threshold number of original pictures (e.g., the first 25 pictures) may be loaded based on the first thread, and a subsequent part of the second threshold number of original pictures (e.g., the second 25 pictures) may be loaded based on the second thread. Therefore, the two threads are used for loading a part of original pictures respectively, and the loading efficiency is improved.
In an embodiment according to the present invention, after each time a second threshold number of original pictures are loaded into the system memory 106 and a corresponding second threshold number of thumbnails are generated based on the second threshold number of original pictures, the number of thumbnails currently stored in the system memory 106 is also determined, it is determined whether the number of thumbnails exceeds a predetermined number, and if the number of thumbnails exceeds the predetermined number, the first loaded and generated second threshold number of thumbnails is deleted. Here, the present invention does not limit the specific number of the predetermined number, and the predetermined number may be determined based on the specific configuration of the system memory. In one embodiment, the predetermined number is, for example, 300.
It should be appreciated that the present invention loads or generates only the second threshold number of thumbnails to the system memory at a time, and further controls the total number of thumbnails loaded in the system memory 106 to not exceed the predetermined number, which ensures that the loaded thumbnails do not occupy a large space in the system memory 106, and is beneficial to reducing the memory footprint.
According to the picture display method 200 of the present invention, when displaying a plurality of thumbnails (e.g., a first threshold number), only a second threshold number of pictures, which is greater than the first threshold number, is initially loaded into the system memory, e.g., the second threshold number of original pictures is loaded to generate the corresponding thumbnail. And when the thumbnails in the current system memory cannot meet the display requirement, dynamically loading corresponding original images according to the actual loading requirement based on the switching condition of the thumbnails by the user, and generating new thumbnails with a second threshold value. Therefore, the original pictures are loaded and the thumbnails are generated based on the batch, excessive occupation of a processor and an internal memory caused by loading a large number of all original pictures and generating the thumbnails at one time is avoided, and the thumbnail loading and displaying efficiency is improved.
Further, after the thumbnail is generated each time, the generated thumbnail is stored in a local storage device of the computing device, so that when the thumbnails need to be displayed again, the thumbnails can be directly loaded from the local storage device and displayed without loading the original picture again to generate the thumbnail. Therefore, the original pictures are prevented from being loaded in batch and processed every time the thumbnails are displayed, the time for loading and processing the original pictures is saved, and the efficiency of loading and displaying the thumbnails is further improved.
