A kind of implementation process schematic diagram of photographic method provided by the embodiments of the present application as shown in figure 1, this method application It in terminal, can be executed by the camera arrangement configured in terminal, be applicable to obtain the situation of the virtualization image of better quality, Including step 101 to step 103.

Wherein, the terminal includes the terminal device that smart phone, tablet computer, learning machine etc. are configured with camera arrangement. Application of taking pictures can be installed on the terminal device.

In step 101, the first focusing position and virtualization value of frame image of taking pictures are obtained, and is obtained and first focusing Position and the virtualization are worth the second focusing position of corresponding virtualization frame image.

In the embodiment of the present application, first focusing position is to need to realize the position clearly shot, that is, is finally obtained It blurs in image, clearly image should be presented in the object of the focusing position, and fuzzy figure should be presented in the object of other positions Picture.

Obtaining for first focusing position can be selected by the auto-focusing algorithm of camera arrangement, can also be by user It is selected in preview interface of taking pictures.The virtualization value can be configured according to actual needs by user.For example, can set It is bigger to be set to virtualization value, virtualization degree is higher.

For example, searching corresponding between the first focusing position as shown in Table 1, virtualization value and the second focusing position three Determining the second focusing position for being worth corresponding virtualization frame image with first focusing position and the virtualization of relation table.It needs Bright, first focusing position belongs to different positions from second focusing position.Numerical value in table one can be root The numerical value being calculated according to functional relation, or the numerical value to be obtained according to practical experience.

Table one:

First focusing position	Virtualization value	Second focusing position
			3m	2	5m
3.5m	2	6m

In step 102, when receiving photographing instruction, frame image of taking pictures corresponding with first focusing position is acquired, And acquisition virtualization frame image corresponding with second focusing position.

In the embodiment of the present application, in the acquisition parameters (the first focusing position) for obtaining frame image of taking pictures, and virtualization frame After the acquisition parameters (the second focusing position) of image, i.e., controllable motor driving camera camera lens be moved to corresponding position into The acquisition of capable frame image of taking pictures and the acquisition for blurring frame image.Wherein, virtualization frame image is for carrying out to frame image of taking pictures Image virtualization processing or clearly handled, virtualization frame image obtain corresponding virtualization figure after carrying out virtualization processing to frame image of taking pictures Picture obtains clear image when virtualization frame image clearly handles frame image of taking pictures.It should be noted that the virtualization frame Image and the frame image of taking pictures are the image that camera acquires external optical signals generation when getting photographing instruction.

For example, first acquiring frame image of taking pictures by a camera in the way of continuous shooting, then virtualization frame image is acquired, Obtain frame image and the virtualization frame image of taking pictures.Or multiple cameras are utilized, while collecting the frame image of taking pictures With virtualization frame image.

It should be noted that when acquiring the frame image of taking pictures in the way of continuous shooting with frame image is blurred, due to depositing In the time difference, the displacement of the shake or reference object itself that generate when may shoot because of user is hand-held leads to the bat Inconsistent situation is had according to the content of frame image and virtualization frame image taking, therefore, in the embodiment of the present application, the acquisition Frame image of taking pictures corresponding with first focusing position, and acquisition virtualization frame image corresponding with second focusing position It later, may include taking pictures frame image and the virtualization frame image is aligned to described.

For example, virtualization frame image and frame image of taking pictures are converted and are sheared using alignment algorithm, so that virtualization frame figure Pixel as in is corresponded with the pixel in frame image of taking pictures.Wherein, the alignment algorithm can be general alignment algorithm, For example, forward direction addition algorithm and inverse combinational algorithm.

In step 103, frame image is taken pictures and the virtualization frame image synthesizes to described, is obtained and the virtualization value pair The virtualization image answered.

In the embodiment of the present application, since the focusing position of take pictures frame image and virtualization frame image is not identical, frame of taking pictures Clear area in image and the clear area in virtualization frame image be not identical.That is, have can for the clear area in frame image of taking pictures The virtualization region in virtualization frame image can be corresponded to, therefore, virtualization frame image is can use and frame image of taking pictures is blurred, obtain Blur image, that is, take pictures frame image and the virtualization frame image synthesizes to described, obtain void corresponding with the virtualization value Change image.

Optionally, as shown in figure 3, in some embodiments of the application, the step 103, to the frame figure of taking pictures Picture and the virtualization frame image are synthesized, and virtualization image corresponding with the virtualization value is obtained, may include: step 301 to Step 303.

Step 301, it takes pictures described in calculating the edge strength of each pixel in frame image.

The edge strength of each pixel refers to the weighted value of each pixel eight pixels adjacent thereto.Example Such as, the edge strength of each pixel is obtained by calculating the Sobel Operator (Sobel operator) of each pixel, or passed through The Laplace operator for calculating each pixel obtains the edge strength of each pixel.

Step 302, the edge strength of pixel in frame image of taking pictures described in holding is greater than or equal to the pixel of first threshold Point is constant.

Wherein, the first threshold is configured according to the edge strength of the pixel of focusing position in frame image of taking pictures , the pixel for the edge strength of pixel in frame image of taking pictures to be greater than or equal to first threshold, which is divided into, to be needed to keep Clearly pixel, that is, the pixel of focusing position in the frame image of taking pictures, and by the edge of pixel in frame image of taking pictures The pixel that intensity is less than the first threshold divides into the pixel of non-focusing position, that is, carries out the pixel of virtualization processing Point (pixel to be blurred).

In the embodiment of the present application, since the edge strength of pixel in frame image of taking pictures is greater than or equal to the picture of first threshold Vegetarian refreshments is to need to keep clearly pixel, accordingly, it is therefore desirable to maintain the edge strength of pixel is greater than in the frame image of taking pictures It is or constant equal to the pixel of first threshold, that is, virtualization processing not to be carried out to it, then again to pixel in frame image of taking pictures The pixel that edge strength is less than first threshold carries out virtualization processing.

Step 303, the pixel that the edge strength of pixel in the frame image of taking pictures is less than the first threshold is made For pixel to be blurred, and virtualization processing is carried out to the pixel to be blurred.

Optionally, as shown in figure 4, described to treat virtualization pixel to carry out virtualization processing may include: step 401 to step 403。

Step 401, the edge strength of each pixel in the virtualization frame image is calculated, and calculates the pixel to be blurred First difference of point and the edge strength of the pixel of corresponding position in the virtualization frame image.

For example, the edge strength of the pixel A to be blurred in frame image of taking pictures be a, pixel A and virtualization frame image in Pixel B be corresponding position pixel, and the edge strength of pixel B be b, then the edge strength of pixel A to be blurred with The first difference for blurring the edge strength of the pixel B of corresponding position in frame image is a-b.

Step 402, if first difference is less than or equal to zero, keep the pixel to be blurred constant.

In the embodiment of the present application, since first difference is less than or equal to zero, indicate to take pictures in frame image wait blur The virtualization degree of pixel is greater than the virtualization degree of the pixel of corresponding position in virtualization frame image, that is, the pixel may be The pixel of focusing position in frame image is blurred, therefore, is less than or equal to zero in first difference, needs to keep described to void It is constant to change pixel.

Step 403, if first difference is greater than zero, the pixel to be blurred is replaced with into the virtualization frame image The pixel of middle corresponding position obtains virtualization image corresponding with the virtualization value.

In the embodiment of the present application, by the way that when first difference is greater than zero, the pixel to be blurred is replaced with institute State virtualization frame image in corresponding position pixel, realize using camera shooting virtualization frame image to take pictures frame image into Row virtualization obtains virtualization image corresponding with the virtualization value, and the virtualization image does not need to acquire using depth transducer The depth information of each target object in photographed scene does not need more to combine the depth information to realize image using virtualization algorithm Blur effect；Meanwhile will not be influenced by the resolution ratio and strong reflection object of depth transducer, realize preferably image Blur effect.

Optionally, in order to enable virtualization image is more smooth naturally, in the embodiment of the present application, as shown in figure 5, described right It may include: step 501 to step 503 that pixel to be blurred, which carries out virtualization processing,.

Step 501, the edge of the pixel of corresponding position in the pixel to be blurred and the virtualization frame image is calculated First difference of intensity.

Step 502, if first difference is less than or equal to zero, keep the pixel to be blurred constant.

Wherein, the step 501 is identical or corresponding as the implementation method of the step 401 to step 402 to step 502, Details are not described herein again.

Step 503, if first difference is greater than zero, corresponding first synthesis ratio of the pixel to be blurred is obtained Example, synthesizes the pixel to be blurred using the first synthesis ratio, the pixel after being synthesized, and will be described Pixel after blurring pixel and replacing with the synthesis obtains virtualization image corresponding with the virtualization value；Wherein, described First synthesis ratio is the pixel value of pixel corresponding with the pixel to be blurred in the virtualization frame image in the conjunction Shared ratio in the pixel value of pixel after.

In the embodiment of the present application, by the way that it is corresponding to obtain the pixel to be blurred when first difference is greater than zero First synthesis ratio, and the pixel to be blurred is synthesized using the first synthesis ratio, while will be described to void Change pixel and replace with the pixel after the synthesis, obtains virtualization image corresponding with the virtualization value；Rather than described When first difference is greater than zero, the pixel to be blurred directly is replaced with to the pixel of corresponding position in the virtualization frame image Point, so that pixel after virtualization can be more smooth naturally, will not be too lofty when first difference comparsion is big.

Optionally, if described obtain second difference greater than zero, the pixel corresponding second to be blurred is obtained Synthesis ratio synthesizes the pixel to be blurred using the second synthesis ratio, the pixel after being synthesized, and By the pixel after blurring pixel and replacing with the synthesis, obtains virtualization image corresponding with the virtualization value and wait for void Change the corresponding first synthesis ratio of pixel, comprising: search the between the first difference, virtualization value and the first synthesis ratio three One corresponding relationship obtains the corresponding first synthesis ratio of the pixel to be blurred.

For example, by searching for first between the first difference as shown in Table 2, virtualization value and the first synthesis ratio three Mapping table determines the corresponding first synthesis ratio of the pixel to be blurred.It should be noted that the numerical value in table two can To be the numerical value being calculated according to functional relation, or the numerical value to be obtained according to practical experience.

Table two:

First difference	Virtualization value	First synthesis ratio
			30	2	50%
40	2	40%

Step 601, take pictures the first focusing position and virtualization value of frame image are obtained, obtain with first focusing position and The virtualization is worth the second focusing position of corresponding virtualization frame image, and obtains and first focusing position and the virtualization It is worth the third focusing position of corresponding reference frame image；Wherein, the distance between the third focusing position and camera are greater than The distance between first focusing position and the camera, also, the third focusing position is small at a distance from camera In the distance between second focusing position and the camera.

For example, the first focusing position of frame image is position 72 as shown in fig. 7, camera 71 is taken pictures, camera 71 is clapped The third focusing position for taking the photograph reference frame image is position 73；The distance between the third focusing position 73 and camera 71 L are big In the distance between first focusing position 72 and the camera 71 G, and, the third focusing position 73 and camera 71 Distance be less than the distance between second focusing position 74 and the camera 71 J.

Step 602, frame image of taking pictures corresponding with first focusing position, acquisition and second focusing position are acquired Corresponding virtualization frame image, and acquisition reference frame image corresponding with the third focusing position.

Step 603, it takes pictures described in calculating the edge strength of each pixel in frame image；It is taken pictures in frame image described in holding The pixel that the edge strength of pixel is greater than or equal to first threshold is constant；By the edge of pixel in the frame image of taking pictures The pixel that intensity is less than the first threshold is used as pixel to be blurred.

Step 604, the edge of the pixel of corresponding position in the pixel to be blurred and the reference frame image is calculated Second difference of intensity.

Step 605, if second difference is less than or equal to zero, keep the pixel to be blurred constant.

Step 606, if second difference is greater than zero, corresponding second synthesis ratio of the pixel to be blurred is obtained Example, synthesizes the pixel to be blurred using the second synthesis ratio, the pixel after being synthesized, and will be described Pixel after blurring pixel and replacing with the synthesis obtains virtualization image corresponding with the virtualization value；Wherein, described Second synthesis ratio is the pixel value of pixel corresponding with the pixel to be blurred in the virtualization frame image in the conjunction Shared ratio in the pixel value of pixel after.

In the embodiment of the present application, due between the focusing position of reference frame image and the focusing position for frame image of taking pictures away from Therefore the distance between focusing position from the focusing position and frame image of taking pictures for being less than the virtualization frame image is calculated to void Change the second difference of the edge strength of the pixel of corresponding position in pixel and reference frame image, and according to second difference The precision of the second obtained synthesis ratio is than directly utilizing pixel to be blurred and blurring the pixel of corresponding position in frame image The precision for the first synthesis ratio that first difference of the edge strength of point obtains wants high, in addition, due to the focusing for blurring frame image The distance between position and the focusing position for frame image of taking pictures are greater than pair of the focusing position and frame image of taking pictures of reference frame image Therefore the distance between burnt position blurs the virtualization degree of frame image for reference frame image, virtualization degree will be more Height therefore, can by acquiring a reference frame image between virtualization frame image and frame image of taking pictures in the embodiment of the present application While to realize the precision for guaranteeing synthesis ratio, reach stronger virtualization effect.

It should be noted that the acquisition modes of the second synthesis ratio are referred to the acquisition of the first synthesis ratio Mode, details are not described herein again.

Step 802, frame image of taking pictures corresponding with first focusing position, acquisition and the 4th focusing position are acquired Frame image, and acquisition rear virtualization frame image corresponding with the 5th focusing position are blurred before corresponding.

Step 803, it takes pictures described in calculating the edge strength of each pixel in frame image；It is taken pictures in frame image described in holding The pixel that the edge strength of pixel is greater than or equal to first threshold is constant；By the edge of pixel in the frame image of taking pictures The pixel that intensity is less than the first threshold is used as pixel to be blurred.

Step 804, the side of the pixel of corresponding position in the pixel to be blurred and the preceding virtualization frame image is calculated The third difference of edge intensity；And calculate it is described wait blur pixel and it is described after blur the pixel of corresponding position in frame image 4th difference of the edge strength of point.

Step 805, if the third difference and the 4th difference are respectively less than or are equal to zero, the picture to be blurred is kept Vegetarian refreshments is constant.

Step 806, if the third difference and/or the 4th difference are greater than zero, the third difference and institute State the size of the 4th difference.

Step 807, the to be blurred pixel corresponding third of the third difference greater than the 4th difference is obtained Synthesis ratio synthesizes the pixel to be blurred using third synthesis ratio, the pixel after being synthesized, and By the pixel after blurring pixel and replacing with the synthesis, virtualization image corresponding with the virtualization value is obtained；Its In, third synthesis ratio be it is described before in virtualization frame image pixel corresponding with the pixel to be blurred pixel value The shared ratio in the pixel value of the pixel after the synthesis.

Step 808, the pixel to be blurred corresponding that third difference is less than or equal to the 4th difference is obtained Four synthesis ratios, synthesize the pixel to be blurred using the 4th synthesis ratio, the pixel after being synthesized, And by the pixel after blurring pixel and replacing with the synthesis, virtualization image corresponding with the virtualization value is obtained； Wherein, the 4th synthesis ratio be it is described after in virtualization frame image pixel corresponding with the pixel to be blurred pixel It is worth shared ratio in the pixel value of the pixel after the synthesis.

Due to it is described it is preceding virtualization frame image prospect be it is real, background be it is empty, it is described after virtualization frame image background be Real prospect be it is empty, it is therefore, big by the way that distance of first focusing position apart from camera is arranged in the embodiment of the present application In distance of the 5th focusing position apart from camera, and it is less than distance of the 4th focusing position apart from camera, that is, Virtualization frame image and rear virtualization frame image, can make before the front-end and back-end of the focusing position for frame image of taking pictures acquire respectively Take pictures frame image and meanwhile carry out prospect virtualization and it is background blurring.

It should be noted that virtualization frame image therein can be one in the embodiment that described Fig. 1 to Fig. 7 is described Frame image is blurred before a or multiple, blurs frame image after being also possible to one or more, and reference frame image therein can also Preceding reference frame image is thought or for rear reference frame image, for realizing a scene for carry out prospect virtualization respectively and only being carried on the back The scene of scape virtualization.
