In yet another embodiment of the present invention, described digital image display device also comprises main control unit, is used for going out according to described positional information calculation the display position of described animation data.
The present invention discerns the location by the target body in the logarithmic code image (can be in human body, object, the people's face one or more), correspondingly select suitable animation file to handle, finally add some animated contents to digital image targetedly, make it seem more lively.
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 shows according to image display of the present invention;
People's face that Fig. 2 shows in the digital image detects, and
Fig. 3 shows the human detection in the digital image.
Embodiment
The present invention proposes a kind of digital image display device, profile and position thereof by analyzing and discerning people's face, human body or object in the photo when showing photo, and some animations that can on photo, superpose, it is more lively that image is shown.For example, at superpose the on the face animation of some beards growth of people, the bird of a jump of stack on people's shoulder, some honeybees that dance in the air and butterfly etc. superpose on the flower on the photo.
Fig. 1 is according to digital image display device of the present invention.Preferably, described digital image display device can be a DPF.
As shown in Figure 1, this digital image display device comprises: picture decoding module, buffer memory BUFFERA, buffer memory BUFFER B, animation decoding unit, people's face/human body/object identification and locating module, main control unit, image overlay module, image display.
Under the control of main control unit, the picture decoding module reads the image file in the memory and it is decoded, and the view data that decoding is drawn is placed on buffer memory buffer A then.People's face/human body/object identification and locating module are analyzed the view data in the buffer memory, identify people's face, human body and the object in the view data and calculate their positions, then the classification information and the positional information thereof of the people's face, human body and the object that identify are passed to main control unit.Main control unit is selected suitable animation file according to above-mentioned analysis result from animation file, perhaps select/list to be fit to a plurality of animation file tabulations of target.Described tabulation can be predefined tabulation in the memory, also can be the tabulation that main control unit generates according to analysis result.Main control unit also goes out the animation needs according to the positional information calculation that obtains and where is presented at.Then, main control unit is passed to the animation decoding unit with the indication of described selection and position.According to these indications, the animation decoding unit selects suitable animation file to decode, and the animation decoded result of each frame is all outputed to corresponding assigned address among the Buffer B, by the image overlay module image in A, the B buffer memory is done to output to image after the overlap-add procedure and show output module, for demonstration.Like this, just can show dynamic animation effect on the static photo, make photo lively more and active.
Wherein, people's face/human body/object identification and locating module can detect, discern and locate some predefined targets such as people's face, human body, flower, sky etc.For example, people's face detects and can adopt at present most popular detection algorithm based on statistics, (testing result is seen Fig. 2 as the AdaBoost algorithm, wherein, square frame among Fig. 2 is detected people's face position), human detection can adopt the method (testing result is seen Fig. 3, wherein, has demonstrated the manikin that adopts human body modeling method to set up in the right part of flg) of people's volume modeling; Target such as flower, sky also can utilize texture of their uniquenesses and color characteristic to detect.
Wherein, described image overlay unit can be that view data and animation data are carried out simply transparent (alpha) and/or cover (overlay) handling back output.Under the simplicity of explanation, in computer graphics, the true coloured picture shape of a RGB color model is used by three color information passages of red, green, blue syntheticly, and 8 color depths of each passage amount to 24, comprised all colour informations.Be to realize the transparent effect of figure, take the method for another 8 information of affix in the processing of graphic file and storage, the channel information of each vegetarian refreshments transparency just is called the Alpha passage in this additional representative of graphics.The Alpha passage uses 8 bits, just can represent 256 grades of gray scales, i.e. 256 grades transparency.The Alpha pixel of white (value is 255) is in order to define opaque colour element, and the Alpha passage pixel of black (value is 0) is in order to the definition transparent pixels, and the Alpha pixel of the gray scale between black and white (value for 30-255) is in order to definition translucent pixel in various degree.Thereby the graphics card by 32 buses shows the figure of band Alpha passage, just may present transparent or semitransparent visual effect.On the basis that alpha handles, can cover (overlay) to image and handle.In addition, described image overlay unit also can be at image-context light, and shade and ambient brightness are revised the back stack.In brief, the image overlay unit can have above-mentioned any one function or its and makes up and finish stack.
Wherein, image file among the figure and animation file are stored and/or are formed in advance in the memory (not shown), and described memory can be the internal storage in this equipment, also can be the external memory storage that is connected to this equipment.
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.
