For technical solutions according to the invention are described, below by specific embodiment, describe.
embodiment mono-:
Fig. 1 shows the flow chart of a kind of photographic method that first embodiment of the invention provides, in the present embodiment, user takes pictures again in the place of taking photo, by by the background area comparison of the background area of photo and outdoor scene, with the position of determining that this is taken pictures, details are as follows:
Step S11, obtains the photo that the last time takes pictures and obtain.
In this step, this last time photo that the photo that obtains is taken pictures and obtained in current place before referring to of taking pictures.If last, take pictures the photo storage that obtains in the memory of this photographing device, from memory, recall this photo; If last, take pictures the photo storage that obtains in other memory devices, need find this photo from these other memory devices, and deposit in the memory of this photographing device, then recall this photo from the memory of this photographing device.
Step S12, processes the photo obtaining, and obtains removing foreground area, only the photo of remaining background area.
Can focus on foreground area owing to taking pictures, therefore in foreground area, have more high-frequency signal, and background area can cause picture gelatinization because of the restriction of lens aperture, high-frequency signal is not obvious, as shown in Figure 2.
In this step, can distinguish foreground area and background area according to the different high-frequency signals of foreground area and background area.
Wherein, when removing foreground area by high pass filter, described the photo obtaining is processed, obtained removing foreground area, only the step of the photo of remaining background area specifically comprises:
A1, the photo obtaining is passed through to high pass filter, processes, obtain prospect value and background value after high pass filter, processes, described prospect value is after high pass filter, processes, to obtain pixel value corresponding to foreground area, and described background value is after high pass filter, processes, to obtain pixel value corresponding to background area.
A2, by the prospect value before the prospect value after high pass filter, processes and background value and high pass filter, processes and background value comparison, obtain foreground area and the background area of photo.
A3, removal foreground area, obtain the only photo of remaining background area.
In above-mentioned steps A1～A3, after high pass filter, processes, prospect value can not decay substantially, and background value can be decayed, referring to Fig. 3, and in Fig. 3, background image gelatinization more after high pass filter of gelatinization originally.Substantially unattenuated after high pass filter according to high frequency value (being prospect value), low frequency value is this rule of meeting decay after high pass filter, compare forward and backward prospect value and the background value of high pass filter, processes, the regional determinations that pad value is many are background area, by the few regional determination of pad value, it is foreground area, then remove the image in foreground area, obtain the Background without prospect.
Wherein, when removing foreground area by low pass filter, described the photo obtaining is processed, obtained removing foreground area, only the step of the photo of remaining background area specifically comprises:
B1, the photo obtaining is processed by low pass filter, obtain prospect value and background value after low pass filter is processed, described prospect value is to obtain pixel value corresponding to foreground area after low pass filter is processed, and described background value is to obtain pixel value corresponding to background area after low pass filter is processed.
Prospect value and background value comparison before B2, the prospect value after low pass filter is processed and background value and low pass filter processing, obtain foreground area and the background area of photo.
B3, removal foreground area, obtain the only photo of remaining background area.
In above-mentioned steps B1～B3, after low pass filter is processed, prospect value can decay, and background value can not be decayed substantially, referring to Fig. 4, and in Fig. 4, the gelatinization that becomes after low pass filter of the people's of foreground area image.According to high frequency value (being prospect value), after low pass filter, can decay, this rule and low frequency value substantially can not decay after low pass filter, relatively low pass filter is processed forward and backward prospect value and background value, the regional determinations that pad value is many are foreground area, by the few regional determination of pad value, it is background area, then remove as shown in Figure 5 the image in foreground area, obtain the Background without prospect.
Step S13, carries out translucent processing to the photo of described remaining background area, obtains translucent background area, at display window, shows the described translucent background area of stack mutually and the background area of current outdoor scene.
Step S14, adjusts the angle of camera, makes the background area of outdoor scene and described semitransparent background region overlapping at least partly.
Wherein, can by manually or smart machine automatically the angle of camera is adjusted.
In described step S14, consider that in background area, some object likely can change, such as tree grow up, leaf increases etc., and reason causes that the background area of outdoor scene and described semitransparent background region can not be completely overlapping, now as long as the overlapped object that other does not change is just passable, so as long as background area and the described semitransparent background region of outdoor scene overlap, just can be considered as the size of two background areas identical and do not have skew, this step specifically comprises:
C1, edge treated is carried out in described semitransparent background region, obtain the profile of all objects in described semitransparent background region as shown in Figure 6, and the profile of all objects is divided into one or more polygons as shown in Figure 7.
C2, to the background area of described outdoor scene by edge treated, obtain the profile of all objects of the background area of described outdoor scene, and the profile of all objects of the background area of the described outdoor scene obtaining be divided into one or more polygons.
The polygon that the profile of all objects of the background area of C3, the polygon that the profile of all objects in described semitransparent background region is divided into and outdoor scene is divided into compares, and the angle of camera is adjusted, while at least existing a polygonal size identical with position, judge that the background area of described semitransparent background region and outdoor scene is overlapping at least partly in two background areas.In this step, choose any polygon in the polygon that the profile of all objects in described semitransparent background region is divided into, for example choose the triangle in Fig. 7, with in the background area of outdoor scene, there is identical shaped polygon (being triangle) and compare, if two polygonal varying in size of comparison, but shape is similar, auto zoom camera, or prompting user convergent-divergent camera, again to compare, if it is unsuccessful (as variation has occurred the object of background area that convergent-divergent camera is still compared, for example comparison is same tree, but because growing tall, tree changed the proportionate relationship on each limit of polygon, therefore compare unsuccessful), in the polygon that the profile of all objects in described semitransparent background region is divided into, choose another polygon, with in the background area of outdoor scene, there is identical shaped polygon and compare, until find a polygon that size is identical.Further, after finding the polygon that size is identical, the polygonal position relationship identical according to these two sizes, automated movement camera or prompting user dollying head, make these two polygons overlapping.When above-mentioned two polygons are overlapping, the background area that is considered as described semitransparent background region and outdoor scene is overlapping at least partly, now sends the prompting that background comparison completes: as send the voice message that background comparison completes, or the prompting compared of display background.
After described step S14, can further indicate the photographer shift position of outdoor scene.
The step of the photographer shift position of described indication outdoor scene specifically comprises:
