Description of drawings
Below with reference to accompanying drawings specific embodiments of the present invention is described in detail, in the accompanying drawings:
Fig. 1 is the synoptic diagram according to digital album (digital photo frame) of the present invention.
Embodiment
Fig. 1 is the synoptic diagram according to digital album (digital photo frame) of the present invention.
As shown in Figure 1, this digital album (digital photo frame) comprises picture decoding module, image classification module, main control module, tabulation or database, image display.
Under the control of main control module, picture decoding module reading images file is also decoded to it, and the view data that decoding is obtained is imported the image classification module into then.Should be pointed out that described image file can be stored in the internal storage of digital album (digital photo frame), also can be in its outside storage medium.
The image classification module is analyzed (concrete analytic process elaborates below) to view data, and imports the analysis result that draws into the main control module.
The main control module can deposit analysis result in tabulation or the database for standby.In addition, the classifying content choice menus of image is arranged on the user interface, for example " image of selection landscape class shows ", " selecting figure kind's image to show " or the like.Like this, the user can classify and show selection, and user's selection can be delivered to the main control module, from tabulation or database, select certain class image by the main control module, send into image display to be shown to the user after according to classified information the image file of respective class in the storer being decoded then.In this way, realized the function of classifying and showing according to picture material.
Elaborating the classification that image classification module carried out below handles.
At first, the image classification module is divided into some to view data, extracts the visual signature of each piece view data then.Preferably, the visual signature that is extracted comprises color characteristic and textural characteristics.The space distribution attribute of pixel grayscale in zone of textural characteristics reflection.Texture is used its roughness always and is described, and the size of roughness is relevant with the space repetition period of partial structurtes, and the cycle, the big texture texture littler than the cycle looked coarse.Therefore, we can extract the textural characteristics of object with a kind of grey scale difference statistic law.
Then, to go out this video data block according to the feature identification of being extracted be which kind of object of presetting to the image classification module.For example, identifying it at each piece view data is the mountain, is water, is people's skin or wedding gauze kerchief or the like.More particularly, the image classification module is passed through earlier to extract the color characteristic and the textural characteristics of image or reach other visual signature, carries out the preliminary judgement of a classification by the default mapping relations between these visual signatures and the picture material.
Then, the image classification module is according to the classification that the statistic of classification value and the default image classification probability statistics of all images piece go out entire image, for example be landscape according to, personage according to or wedding photography or the like.
Function according to the classification display image of digital album (digital photo frame) of the present invention has been described above.Further, in display image, can also play the multiple file that is associated with classified image according to digital album (digital photo frame) of the present invention.
In this case, described digital album (digital photo frame) also comprises a contingency table, is used to store the related record in path of various files such as music that digital album (digital photo frame) is about to play simultaneously with image, animation, image, literal.Described various file can be stored in the built-in storer of digital album (digital photo frame), also can be stored in the external various storage mediums of digital album (digital photo frame).Preferably, described contingency table is a text, is stored in internal system.Contingency table can manually be generated under the System menu prompting by the user, for example the user can be under menu prompt, manually select to set up related with certain music file in the external storage medium of digital album (digital photo frame) existing certain class image file in the digital album (digital photo frame) internal memory, generate a related record thus, be stored in the contingency table.For example, the image of wedding gauze kerchief class is interrelated with the audio file of " wedding march ", the image of landscape class is interrelated with the audio file of " high mountain and great rivers ".Again or as, animation files such as figure kind's image and glasses, cap, beard is interrelated, the animation file of the image of landscape class and bird, honeybee, butterfly and so on is interrelated.Contingency table also can be generated according to pre-defined rule automatically by system.Such as, the filename of being stored in the systematic search storer, with name is identical but the file that type is different is interrelated.For example, " wedding 2008.jpg " and " wedding 2008.txt " these two files are interrelated.Above-mentioned association all generates an associated record, is stored in the contingency table.Like this, in demonstration that image is classified, the main control module can be controlled the file that the digital album (digital photo frame) broadcast is associated with current shown image by searching contingency table.
Should be pointed out that when described file is animation file described digital album (digital photo frame) also comprises animation file decoder module, people's face/object/person body identification locating module, image overlay module.When needs during according to the image category playing cartoon file, the picture decoding module is decoded to image file and is drawn view data and it is sent into buffer memory A.Human body/object/person face identification locating module is analyzed the view data among the buffer memory A, identifies human body/object/person face wherein and draws its positional information, then the classification and the positional information that identify is passed to the main control module.The main control module according to analyze with animation that classified image is associated in select, and calculate the display position of selected animation data, selection result and the position that calculates are informed the animation decoder module.The animation decoder module is decoded according to selection result and the choice of location animation file that calculates and is drawn animation data, and imports it among the buffer memory B described display position.Then, main control module controls image overlay module is carried out it being outputed to image display after the overlap-add procedure to the view data in two buffer memorys and animation data and is shown.
Should also be noted that when described file was audio file, described digital album (digital photo frame) also should comprise audio decoder module and audio-frequence player device.When needs during according to the image category displaying audio file, the main control module finds the audio file that is associated with current display image by searching contingency table, the control audio decoder module is decoded to it, sends into audio-frequence player device then, plays when showing present image.
In addition, when described file was literal, image or the like, its related playing process was very similar to said method, therefore repeated no more.
Obviously, under the prerequisite that does not depart from true spirit of the present invention and scope, the present invention described here can have many variations.Therefore, the change that all it will be apparent to those skilled in the art that all should be included within the scope that these claims contain.The present invention's scope required for protection is only limited by described claims.
