Abstract
The invention discloses a method for displaying nine multimedia file thumbnails on each page through an automobile data recorder to achieve a rapid file previewing effect.According to the basic scheme, files are previewed on a file previewing interface in a 3*3 grid mode, an upper key and a lower key are pressed transiently to switch the files one by one, and the upper key and the lower key are pressed for a long time to switch the files in a page turning mode.The specific implementation method includes the steps that 3*3 grids are drawn on the interface; the automobile data recorder acquires file names of nine multimedia files needing to be displayed currently from a database, the nine thumbnails are generated through the first frame I of a video file or images of an image file, then the 3*3 grids are sequentially filled with the nine thumbnails one by one, and the nine thumbnails are displayed on a screen; then the upper key and the lower key are pressed transiently to switch the files one by one, and the upper key and the lower key are pressed for a long time to switch the files in the page turning mode.Thus, a user can preview multiple files on one page, and the rapid previewing effect can be achieved by switching nine files at a time.
Description
Technical field
The present invention relates to field of filesystems, particularly to a kind of method of rapid preview multimedia file on drive recorder.
Background technology
At present, the real-time imaging in drive recorder energy registration of vehicle driving process, provide scene of a traffic accident voucher for car owner, it has also become the indispensable selection of increasing car owner's trip.Increasing along with memory space, multimedia file also gets more and more, and at present on the market, drive recorder button is less, and what mostly adopt is the single page mode that shows a file, and this method is very slow when preview file.When file has up to a hundred, some file of user's preview, it may be necessary to by up to a hundred buttons, Consumer's Experience is excessively poor.
Summary of the invention
In order to overcome the deficiency that existing drive recorder previewing file method is too slow, Consumer's Experience is not good, the method that a kind of drive recorder each page provided by the present invention shows nine multimedia file thumbnails, reach the effect of rapid preview file.
The technical solution adopted for the present invention to solve the technical problems is: draw the grid of 3x3 on interface；Drive recorder obtains the filename of nine media files currently shown from data base, first I frame of video file or the picture of picture file is utilized to generate nine hypertonic sketch maps, then nine hypertonic sketch maps are filled in 3x3 grid in order one by one, and are shown on screen；Subsequently, switch file by short in turn by upper and lower button, long by upper and lower button page turning switching file.
The invention has the beneficial effects as follows: user on one page can nine files of preview, and can once switch nine files by the mode of page turning.Than existing method, it is greatly accelerated file switch speed, is really achieved the effect of rapid preview file.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the flow chart of the present invention, concisely illustrates the flow process of drive recorder display multimedia file thumbnail.
Fig. 2 is the button operation on drive recorder of the present invention.
Detailed description of the invention
Concrete, the detailed example of the present invention is presented herein below, and described example is only the actually used example of the present invention, and non-limiting ability example.
The invention provides a kind of method that drive recorder shows multiple multimedia file thumbnail, drive recorder all can have both direction key: on directionkeys under (201) and directionkeys (202), the present invention is exactly the function that make use of the two direction key to achieve file rapid preview.It is embodied as step to include:
(1) when drive recorder images or taken pictures, joining in data base by the fileinfo of generation, fileinfo includes the absolute path of file, file size, file type, file creation time.
(2) when entering drive recorder file display interface, by the data in data base by creating time-sequencing, obtaining up-to-date nine file, record current sequence number is 0.
(3), under file interface, background segment is become the preview area of 3x3 grid configuration.
(4) use multimedia interface, obtain the thumbnail of file one by one, be filled into the preview area that file interface is corresponding.
(5) thumbnail generated leaves under current directory, can directly use, it is not necessary to obtain file thumbnail with multimedia interface again during display thumbnail next time.
(6) short switch file in turn by up and down arrow keys (201 or 202), press and determine that key can the currently selected picture of full-screen preview or video file.
(7) length presses (202) under directionkeys, it is possible to page turning downwards, and when downward page turning, serial number is added one by drive recorder, calculates 9 × serial number as file index, if file index value is more than total number of files, then serial number is set to 0 again.
(8) length presses (201) on directionkeys, it is possible to page up, when paging up, serial number is subtracted one by drive recorder, calculating 9 × serial number as file index, if file index value is less than 0, then serial number is set to total number of files again divided by 9.
(9) during page turning, the file being currently displaying can be stopped, emptying the thumbnail having shown that, then show the thumbnail after page turning again.
Claims (4)
1. the method for a drive recorder rapid preview multimedia file a, it is characterised in that interface can show the thumbnail of nine multimedia files, and can rapid page.
2. the method for a kind of drive recorder rapid preview multimedia file according to claim 1, it is characterised in that drive recorder has at least both direction button: on directionkeys, under directionkeys.
3. data can be deleted, add, sorting operation by the method for a kind of drive recorder rapid preview multimedia file according to claim 1, it is characterised in that drive recorder has data base.
4. the method for a kind of drive recorder rapid preview multimedia file according to claim 1 and 2, it is characterised in that length presses up and down arrow keys, it is possible to carry out upper and lower page turning.
