The thumbnails are read from the target (four) buffer and their settings are displayed and/or the thumbnails completed by the instant conversion are set on the screen display. The mobile device capable of quickly displaying the picture comprises the following modules: the initialization module 35 is configured to configure and initialize the last glory buffer of the thumbnail used by the fast display picture and the length of the current screen buffer. The previous screen buffer is used to save a thumbnail of the picture of the last camp buffer. The current screen buffer is used to store the thumbnail of the picture that needs to be buffered on the current screen. The thumbnail buffer module is used to save the picture. Copy or paste the thumbnail of the image corresponding to the index of the picture listed in the current screen buffer into the current screen buffer in the screen buffer or thumbnail file storage area, and/or the non-existent listed in the current screen buffer The screen corresponding to the index in the screen buffer or the thumbnail file storage area is instantly converted; the instant conversion result processing module is used to paste the instant converted thumbnail image into the current screen buffer; and the thumbnail image is read. A module that reads thumbnails from the current screen buffer and sets them on the screen display. The low-cost action splitting using the thumbnail buffering mechanism of the present invention #图片浏201013515 The browser 'whether in the current screen moving selection box or scrolling the picture file column. Table 'all thumbnails on the new screen can be At present, the screen buffer is read, and the display efficiency of the picture is improved. [Embodiment] As shown in Fig. 1, ' is an architectural diagram of a preferred embodiment of a mobile device capable of quickly displaying pictures. The mobile device 1 includes a display screen area 2, a storage body 3. The storage body 3 includes a thumbnail storage area 31 and a quick display picture unit 32. The thumbnail storage area 31 is configured to store a thumbnail of the picture in the mobile device 1. The stored thumbnail source includes: the camera module stores the original picture immediately after taking the picture, and saves the thumbnail of the original picture into the original picture. The thumbnail file storage area 31, or the original picture and its thumbnail image are transmitted into the mobile device 1 through the way of image file transmission, or the original picture is stored in the thumbnail image after being instantaneously converted when the mobile device is browsed. In the file storage area. The quick display picture unit 32 is loaded and run in the picture browser processing program. The quick display unit 32 includes an initialization module 32, a thumbnail buffer module 321, a thumbnail instant conversion result processing module 322, a thumbnail reading module 323 and a space release module 324. The modules described in the present invention are all software-implemented programs. The modular design of the software brings benefits to the modification and shifting of the program in the future. If some functions of the program need to be modified, as long as the module related to the function is modified, other modules not related to the function are not required. Modification; if the modular software system needs to be moved, it only needs to modify the module related to the platform. The initialization module 320 is configured to configure and initialize the number of inflammation 201013515 used by the quick display picture and the required buffer. In the preferred embodiment, the required buffer includes a thumbnail buffer. The . parameters used include the number of thumbnails on the screen, the length of the screen buffer, and the size of the thumbnail icon. The initialization module 320 configures the size of the thumbnail buffer of the thumbnail according to the storage capacity of the action slot 1. In general, the length of the configured thumbnail buffer is the number of thumbnails on the screen plus the number of thumbnails on the top and bottom of the screen. In the preferred embodiment, the number of thumbnails on the screen is 2χ2, the number of thumbnails in one column is 2, and the number of thumbnails in two columns is 2χ2, so the length of the thumbnail buffer is 2χ2+2χ2=8 One. The thumbnail screen buffer is divided into two thumbnail buffers. Because the contents of the previous screen need to be buffered differently from the content that the current screen needs to buffer, but their contents may be partially the same, the thumbnail buffer of the thumbnail is divided into the previous screen buffer and the current screen buffer. . The last screen buffer saves the thumbnail buffer content of the previous screen. The current screen buffer saves the screen thumbnail buffer content and can copy the required thumbnails from the previous screen buffer. The thumbnail content saved by the thumbnail screen buffer includes a thumbnail image, a storage path of the image corresponding to each thumbnail image, and an index of each image. The index of each picture is associated with the storage path of its corresponding picture. The index of the picture is used to identify whether the thumbnail of the previous screen buffer and the current screen buffer belongs to a picture. Referring to Figure 3, Figure 3 (4) is the file list, Figure 3 (Β) is the last screen buffer, and Figure 3 (C) is the current screen buffer. The thumbnails of the two rows of indexes 6, 7, 8, and 9 in Figure 3 (Α) are the inner valleys of the last 201013515 screen, and the two rows of indexes 401, 8, and (7) The corresponding J-slice thumbnail is what the current screen will display. Figure 3(8) shows the contents of the last snippet buffer, and Figure 3(c) shows the contents of the current glory buffer. Figure 3 fA, mi 圃ΙΑ) Figure 3 (B) and Figure 3 (C), the current content of the screen buffer has three rows of indexes 8, 9, iq, the corresponding image thumbnails are present on In the camp buffer, so you can copy it directly from the previous screen buffer. The content of the bottom line is not in the previous screen buffer. Then you need to convert the thumbnail or save it from the thumbnail file. Read out in area 31. The initialization module 320 configures the size of the thumbnail groove in accordance with the capacity of the storage unit 3 of the mobile device i. In the preferred embodiment, a thumbnail of a picture in the following format is stored in the thumbnail storage area: a photo taken by the camera module (a JPG picture having a size exceeding 640×480), and a size is input in the file transfer mode. More than 1024x768 images. There are three sources of the thumbnail: instant conversion, thumbnail file storage area 31 © and thumbnail screen buffer. The thumbnail of the instant conversion refers to the instant conversion of the original image into a thumbnail, which is the slowest of the three methods. The thumbnail image from the thumbnail file storage area means that the thumbnail image is stored in the thumbnail file storage area after the previous instant conversion, or after the camera module takes the photo or the image file is transmitted to the moving device 1 The stored 'but not all of the original pictures have a thumbnail =, therefore, in the case of the mobile device 1 to make the thumbnail of the original picture corresponding to the original picture, the original picture needs to be converted in real time to obtain a thumbnail. The screen buffer from the thumbnail means that the thumbnail is stored in the previous screen buffer, which is the fastest of the three methods. 201013515 The thumbnail buffer module 321 is configured to search whether the thumbnail of the image corresponding to each index in the current screen buffer exists in the previous screen buffer, and the thumbnail of the image corresponding to the index exists on the previous screen. When the buffer is in the buffer, the thumbnail of the image corresponding to the index is pasted into the current screen buffer; when the thumbnail of the image corresponding to the index does not exist in the previous screen buffer, try to save from the thumbnail file. The thumbnail of the picture corresponding to the index is read in the area 31. If the reading is successful, the thumbnail of the picture corresponding to the index is copied and pasted from the thumbnail file storage area 31 I to the current screen buffer; if the thumbnail file is read If the storage area fails, the instant conversion request is transmitted to the picture decoder to perform thumbnail conversion on the picture corresponding to the index. The instant conversion result processing module 322 is configured to paste the converted thumbnail copy into the current screen buffer, and if the converted thumbnail image is a thumbnail image to be displayed on the current screen, the instant conversion result processing The module 322 needs to set the converted thumbnail to be displayed in the display screen area 2. The thumbnail reading module 323 is configured to read a thumbnail image to be displayed from the current screen buffer and set it to be displayed in the display screen area 2; if the thumbnail image is not in the current screen buffer, the The thumbnail image still needs to be converted in real time, and the converted thumbnail image is later set by the instant conversion result processing module to be displayed on the display screen area 2. The space release module 324 is configured to release the parameters configured by the initialization module 320 and initialized and the memory space occupied by the buffer when needed. For example, when it is necessary to reconfigure the length of the thumbnail buffer or the size of the thumbnail file, etc., the space release module 324 can free up space for reconfiguration. 11 201013515 Figure 2 is not a flowchart of the method for quickly displaying pictures in the mobile device of the present invention. Before performing a quick display of the picture, you need to prepare the steps, starting from the initial =32_ and configuring it on the mobile device! Quickly display the picture and the buffer. In the preferred embodiment, the required buffer packet = the honor buffer of the graph. The parameters used include the number of thumbnails on the screen, the length of the screen buffer, and the size of the thumbnail file.纟 Step S2GG in the user's picture file list or in the thin picture. When you want to switch from the current screen to the next screen, the user needs to scroll or re-read the picture file list, as shown in Figure 3(A). Step S202, when the user stops scrolling or stops reading the image slot list, the index of the new image to be displayed is listed on the screen, and the image index displayed on the current screen is displayed for the new image. The image index of the buffered thumbnail is listed in the current f-screen buffer. The list of images in the current camp buffer can be the index of the current picture on the screen, the index of the current list of pictures above and below. Referring to FIG. 3 (A), (B), (C), in the current screen buffer shown in (c), the picture index shown by 403 is located in the previous screen buffer, and the picture index of 4 is shown. Did not appear in the previous screen buffer. In step S204, the thumbnail buffer module 321 checks the thumbnail source of the picture listed in the current screen buffer. That is, according to the image index 'searching the last screen buffer' listed in the current camp Xu area, when the index of the picture is searched in the last screen line, it indicates that the thumbnail of the picture exists on the picture. In the screen buffer, the process proceeds to step S205; when the index of the picture is not found in the last screen buffer 12 201013515 area, the thumbnail file storage area 31 is attempted to be read, if in the thumbnail file storage area 31 Reading the index of the picture, indicating that the thumbnail of the picture to be displayed exists in the thumbnail slot storage area 31 * proceeds to step S206; if the thumbnail file storage area 31 fails to be processed, the instant conversion thumbnail is transmitted The demand proceeds to step S208. In step S205, the thumbnail buffer module 321 copies the thumbnail of the picture from the previous screen buffer according to the index of the picture. © step S206, the thumbnail buffer module 321 copies a thumbnail of the picture from the thumbnail file storage area 31 according to the index of the picture. In step S208, the thumbnail buffer module 321 transmits the request for immediate thumbnail conversion to the picture decoder for thumbnail conversion, and converts the original image into a thumbnail image. The conversion process takes a lot of time, so the conversion thumbnail is not synchronized with the thumbnail buffer mechanism. When a request for immediate conversion to a thumbnail is made for an image, the image corresponding to the next listed image index can be checked immediately. φ Step S210, the thumbnail buffer module 321 pastes the thumbnail of the copy into the current screen buffer, or pastes the converted thumbnail image into the current screen buffer by the thumbnail instant conversion result processing module 322. . Step S212, the thumbnail buffer module 321 determines whether the picture indexes listed in the current screen buffer are all checked, and when there are still picture indexes not checked, returns to step S204, when all the pictures index listed in the current screen buffer are returned. If the check is out of date, the process proceeds to step S214. In step S214, the thumbnail reading module 324 reads the thumbnail from the current screen buffer and sets the read thumbnail to the screen for display. If the thumbnail of the image corresponding to the image index listed in 13 201013515 is not displayed on the screen, the table shows that the thumbnail of the image is being converted. After the conversion is completed, the thumbnail is converted, and the result processing module is converted. 322 then set it to display on the screen. In the use of the mobile device 1, when the length of the thumbnail buffer or the size of the thumbnail file needs to be reconfigured, the space release module 324 can release the parameters and buffers configured and initialized by the initialization module 320. The storage space occupied by the area is reconfigured to reconfigure the length of the thumbnail buffer and the size of the thumbnail file. The above is only the preferred embodiment of the present invention, and has been used in a wide range of applications. Any other equivalent changes or modifications which are not departing from the spirit of the present invention should be included in the following claims. Inside.
