Specific embodiment
Hereinafter, by preferred embodiments of the present invention will be described in detail with reference to the annexed drawings.Note that in the specification and drawings In, there is substantially the same step and element to be denoted by the same reference numerals, and to the repetition solution of these steps and element Releasing will be omitted.
In following embodiment of the invention, the concrete form of image capture device includes but is not limited to intelligent mobile electricity Words, personal computer, personal digital assistant, portable computer, tablet computer, multimedia player etc..According to this hair A bright example, image capture device can be hand-hold electronic equipments.Preferably, another example according to the present invention, image Acquisition equipment, which can be, wears electronic equipment.In addition, another example according to the present invention, image capture device may include eyeglass portion Part and the acquisition unit and display unit being correspondingly arranged with the lens component.
Fig. 1 depicts the flow chart of the method 100 of image procossing according to an embodiment of the present invention.Next, with reference to Fig. 1 Method to describe image procossing according to an embodiment of the present invention.The method 100 of image procossing can be used for above-mentioned Image Acquisition and set It is standby.
As shown in Figure 1, in step s101, being acquired to the first scene, and show realtime graphic collected.As above Described, an example according to the present invention, image capture device may include lens component and corresponding with the lens component set The acquisition unit and display unit set.In the case, in step s101, when in the visible area that lens component is located at user When, user can be acquired through the first scene of lens component viewing by acquisition unit, and obtain realtime graphic.Example Such as, lens component may be provided above or below acquisition unit.Therefore, when in the visible area that lens component is located at user When, acquisition unit can carry out Image Acquisition along the direction similar with user's view direction, to obtain user through lens component The real-time image acquisition of viewing.
In step s 102, determine in realtime graphic whether operating body occur.An example according to the present invention, operation Body can be the finger of user.Alternatively, operating body is also possible to pre-set operating pen etc..
When determine there is operating body in realtime graphic when, in step s 103, by realtime graphic with operating body The corresponding acquisition target in position is as target object.An example according to the present invention can identify reality in step s 103 first When image in acquisition target, and obtain each acquisition target first position in realtime graphic.Then in the acquisition identified In object, determine its first position the first acquisition target corresponding with the position of operating body as target object.
Selectively, after determining its first position acquisition target corresponding with the position of operating body, in step s 103, It may further determine that the first distance between object corresponding with the first acquisition target in the first scene and image capture device, and It determines between object corresponding with the acquisition target other than the first acquisition target in the first scene and image capture device Second distance determine that the difference between its second distance and first distance is less than or waits then in the object of the first scene In the target object of preset distance difference, finally using acquisition target corresponding to target object as target object.According to this hair In bright example, the object in the first scene, which can be, does not have lived object, such as building, trees etc..In addition, first Object in scape is also possible to lived object, such as people, animal etc..
Fig. 2 a to Fig. 2 c is to show an example according to the present invention, and the example of target object is determined in realtime graphic The explanatory diagram of situation.In the example shown in Fig. 2 a to Fig. 2 c, the realtime graphic 200 of the first scene collected is shown.Such as figure Shown in 2a, when determine there is operating body 210 in realtime graphic 200 when, first identify realtime graphic in acquisition target 221, 222,223 and 224, and obtain the first position in realtime graphic of acquisition target 221,222,223 and 224.For example, can be to real-time Image 200 executes contours extract, so that the profile of each acquisition target is obtained, so that it is determined that each acquisition target and its position.
Then as shown in dotted line frame in Fig. 2 b, in realtime graphic 200, the position of its first position Yu operating body 210 is determined Corresponding acquisition target 222 is set as target object.In addition, as shown in the dotted line frame in Fig. 2 c, determine in the first scene with First distance between the corresponding object of first acquisition target 222 and image capture device, and determine in the first scene with Between acquisition target 221,223 and 224 corresponding objects and image capture device other than the first acquisition target 222 Two distances.Then in the object of the first scene (that is, object corresponding to object 221,222,223 and 224), determine its second Difference between distance and first distance is less than or equal to the target object of preset distance difference, finally will be corresponding to target object Acquisition target 223 and 224 is also used as target object.To which user can once specify multiple target objects in realtime graphic, Without specifying one by one to target object, the operation of user is facilitated.
It returns to Fig. 1 and determines target area of the target object in realtime graphic in step S104.Then in step In S105, image procossing is carried out to target area.Fig. 3 a is to show an example according to the present invention, true as shown in Figure 2 Set the goal object, and determines target object behind the target area in realtime graphic 200, carries out image procossing to target area Illustrative case explanatory diagram.As shown in Figure 3a, an example according to the present invention, in step s105, determined by adjusting The transparency of target area 311,312 and 313, virtualization processing can be carried out to target area 311,312 and 313, to blur Target object 222,223 and 224.
Fig. 3 b is to show another example according to the present invention, determines target object as shown in Figure 2, and determine target Object carries out the explanatory diagram of the illustrative case of image procossing to target area behind the target area in realtime graphic 200.Such as figure Shown in 3b, an example according to the present invention can get second image relevant to realtime graphic 200 in step s105 321,322 and 323, and second image 321,322 and 323 is filled into target area 311,312 and 313 to cover The target object.
In the method for above-mentioned image procossing provided in this embodiment, by image capture device real-time figure collected Image procossing is carried out to the target area determined according to the position of operating body as in, user can be effectively shielded and be not intended to concern Object, so that reducing user is not intended to interference of the object of concern to shown content, and user does not need to hide It is not intended to the object of concern and exchanges shooting angle.
In the following, illustrating the image capture device of embodiment according to the present invention referring to Fig. 4.Fig. 4 is to show according to the present invention The exemplary block diagram of the image capture device 400 of embodiment.As shown in Figure 4, the image capture device 400 of the present embodiment Including acquisition unit 410, display unit 420, operating body recognition unit 430, object determination unit 440, area determination unit 450 With image processing unit 460.The modules of image capture device 400 execute the method 100 of the matching unit in above-mentioned Fig. 1 Each step/function, it is therefore, succinct in order to describe, no longer specifically describe.
