Below in conjunction with accompanying drawing, the main of the embodiment of the present application technical scheme is realized principle, embodiment and be explained in detail the beneficial effect that should be able to reach.
As shown in Figure 1, the embodiment of the present application provides a kind of image processing method, and can be applied in the electronic equipments such as digital camera, digital camera, smart mobile phone or panel computer, described method comprises:
S10: carrying out image acquisition region, in image acquisition process, determining destination object from current frame image.
S11: determine the first area image of described destination object in described current frame image.
S12: process described first area image, obtains second area image.
S13: described second area image and described current frame image are synthesized, obtains synthetic frame image.
In S10, current frame image is the preview image be presented on the display unit of electronic equipment, and the destination object determined from current frame image can be personage, animal or building etc.Concrete, in the embodiment of the present application, can by following three kinds of mode determination destination objects.
First kind of way, carries out object Intelligent Recognition to described current frame image, determines the first object from described current frame image.
Specifically, intelligent object identification can be recognition of face, then will comprise the whole human body image of face as destination object.Intelligent object identification also can be colour recognition, outline identification etc., and the object of identification can a water tumbler, and an animal or a building building etc., the application is not restricted this.
The second way, the First Eigenvalue obtaining the first object on described current frame image and the default characteristic value pre-set; Judge whether described the First Eigenvalue mates with described default characteristic value; If described the First Eigenvalue and described default characteristic matching, determine that described first object is described destination object.
In the second way, the characteristic value of multiple object in electronic equipment or cloud server, can be prestored.For example, the characteristic value of object can be the face characteristic value of user, the contour feature value etc. of animal; The characteristic value of the object that the characteristic value preset was taken before can being electronic equipment also can be the characteristic value of the object of user's typing; Default characteristic value can be kept in the local data base of electronic equipment, and also can be kept in cloud database, the application does not all limit this.
Further, obtain the First Eigenvalue of the first object on current frame image at electronic equipment after, the First Eigenvalue is mated with the default characteristic value in local data base or cloud database, if there is the default characteristic value of mating with described the First Eigenvalue, then determine that the first object is described destination object.
The third mode, if Non-precondition characteristic value in electronic equipment, or the default characteristic value of not mating with the First Eigenvalue of the first object, then can contrast current frame image and previous frame image, detect moving object.If there is moving object, then using moving object as described destination object.
In the embodiment of the present application, after determining destination object by S10, electronic equipment performs S11, determines the first area image of described destination object in described current frame image.Concrete, electronic equipment can calculate the outline of destination object, determines that the image in described outline is described first area image, and then from current frame image, determines the first area image at destination object place.
Next, electronic equipment enters S12, processes described first area image, obtains second area image.In the embodiment of the present application, following three kinds of implementations of S12 are described, in specific implementation process, are not limited to following three kinds of implementations.
First kind of way, carries out convergent-divergent to described first area image.
Specifically, first, electronic equipment needs the scaling determining first area image.In specific implementation process, electronic equipment can according to user's gesture operation determination scaling on the display unit, also can according to the position relationship determination scaling of first area image in display unit.
Wherein, when according to the position relationship determination scaling of first area image in display unit, as shown in Figure 2, first, S20 is performed: the central point determining described first area image.
Specifically, as shown in Figure 3, first can determine the minimum rectangle ABCD comprising first area image, as shown in the dotted line frame in Fig. 3, the limit of rectangle is parallel with the limit of display unit respectively, then the geometric center of rectangle ABCD is defined as the central point of first area image, as shown in the intersection point of dotted line in Fig. 3.
Then, electronic equipment performs S21: choose multiple marginal point from the edge of described first area image.
In the embodiment of the present application, in a kind of optional embodiment, the number of marginal point can be determined.Suppose to need M marginal point, then according to the number of marginal point and the length of image border, first area, be spaced a distance and choose a marginal point, thus obtain M marginal point, wherein, spacing distance is the length at the edge between two marginal points.
In another kind of optional embodiment, spacing distance can be determined, hypothesis margin distance is 1mm, then according to spacing distance, on the edge of first area image, interval 1mm chooses a marginal point.
Next, electronic equipment performs S22: obtain first distance of described central point to the first marginal point in described multiple marginal point, and point at described central point on the direction of described first marginal point, described central point is to the second distance at the edge of described display unit.
As shown in Figure 3, central point is O, and the first marginal point is P, and the first distance is the distance of line segment OP, and point on the direction of the first marginal point P at central point O, the distance of line segment OQ is above-mentioned second distance.
Then, electronic equipment performs S23: the ratio determining described second distance and described first distance, and then obtains and described multiple marginal point multiple ratio one to one, and minimum ratio in described multiple ratio is defined as described scaling.For example, suppose OP=1, OQ=2, then the ratio determined by line segment OP and OQ is 2, if the ratio determined by other marginal points is all greater than 2, then determines that scaling is 2, by first area Nonlinear magnify twice.
Further, in the embodiment of the present application, in order to optimize the display effect of the image after amplification, described method also comprises:
According to described scaling, described first area image is zoomed in or out, obtain described second area image; Wherein, the resolution of described second area image is identical with the resolution of described first area image.In specific implementation process, can be amplified first area image by interpolation algorithm, obtain second area image, and then make the resolution of second area image identical with first area image.
In another kind of optional embodiment, the resolution due to the image acquisition units of electronic equipment is greater than the resolution of display unit, and therefore, the resolution of the image obtained by image acquisition units collection is greater than the resolution of display unit.Display unit, when showing image, can adjust the resolution of image, be adjusted to the resolution of mating with display unit and show.If the resolution of second area image is greater than the resolution of display unit, then electronic equipment is when showing synthetic frame image on the display unit, can to second area image, and the remainder except second area image in synthetic frame image adjusts, the resolution of last display image is on the display unit mated with display unit, and the resolution of second area image is identical with the resolution of remainder, there will not be the resolution of second area image lower than the situation of the resolution of remainder, in this case, electronic equipment can directly amplify first area image, obtain second area image.
In the embodiment of the present application, as shown in Figure 4, after obtaining the second area image after amplifying, electronic equipment performs S13, described second area image and described current frame image is synthesized, and obtains synthetic frame image.Specifically, comprising:
S131: the central point and the primary importance of described central point in described current frame image that obtain described first area image.Wherein, central point can for the central point determined in S20, and the primary importance of central point in current frame image can represent with pixel position.
Next, electronic equipment performs S132: determine the second place of described central point in described second area image.Wherein, the second place can use the pixel positional representation that central point is corresponding in second area image.
After acquisition primary importance and the second place, electronic equipment performs S133: described second area image and described current frame image are synthesized, and to make described primary importance and described second place overlap, obtains described synthetic frame image.For example, the pixel that the central point of first area image is corresponding is p
1, the pixel that the central point of second area image is corresponding is p
2, then when composograph, by by pixel p
1with pixel p
2overlap, and then obtain described synthetic frame image.
Next, the second implementation of S12 is described.
The second way, moves described first area image.
First, electronic equipment determines primary importance from described current frame image.In the embodiment of the present application, electronic equipment can determine primary importance according to user's gesture operation on the display unit, for example, after determining first area image, user can drag described first area image on the display unit, first area image is dragged to primary importance from home position, and when user stops drag operation, the position of stopping is described primary importance.
Then, described first area image is moved to described primary importance from the second place at image place, described first area, obtain second area image.Wherein, the second place is the home position of first area image in current frame image.
Further, after moving first area image, can also repair the region, home position in current frame image, then, electronic equipment performs S13, the image after reparation and second area image is synthesized, and obtains synthetic frame image.
Next, the third implementation of S12 is described.
The third mode, carries out picture editting to described first area image.
Specifically, carry out editor to first area image and be included on the image of first area and increase light, increase filtering effects, it is outstanding etc. to carry out edge, and to obtain second area image, the application does not limit this.Then, electronic equipment performs S13, second area image and current frame image is synthesized, and obtains synthetic frame image.

The second way, when electronic equipment moves first area image for being operating as of carrying out of current frame image, S31 comprises, record the position of described second area image in described synthetic frame image, or described second area image in described synthetic frame image with the relative position relation of at least one other object; According to described position or described relative position relation, the area image at described destination object place is moved.For example, suppose in synthetic frame image, the position at second area image place is a-quadrant, then, when processing other two field pictures, the area image at destination object place is moved to a-quadrant.Again such as: suppose in synthetic frame image, the position at second area image place is B object in image and between C object, then, when processing other two field pictures, moved between B object and C object by the area image at destination object place.
In specific implementation process, at least one other object can be people, animal, or building etc., the application does not limit this.By the second way, destination object can be moved to the position not allowing to take pictures by user, or the position that destination object can not arrive.
The third mode, when electronic equipment is edited first area image for being operating as of carrying out of current frame image, records edit effect when editing described first area image in described current frame image; According to described edit effect, the area image at described destination object place is edited.For example, suppose when editing the first area image in current frame image, filtering effects is increased to first area image, then, when processing other two field pictures, filtering effects is increased to the area image at destination object place.
In the embodiment of the present application, carrying out in video process to image acquisition region, by synthetic frame Image Saving in video file.Further, at the processing rule according to current frame image, after the destination object in other two field pictures is processed, the synthetic frame image generated also is saved in electronic equipment successively, thus generates complete video file according to other two field pictures.
