Below with reference to the accompanying drawings method, device and electronic equipment that the control scene photograph Live Photo of the embodiment of the present invention generates are described.
Fig. 1 is the flow chart controlling the method that scene photograph Live Photo generates according to an embodiment of the invention.It should be noted that in an embodiment of the present invention, electronic equipment can be but be not limited to mobile terminal, has the terminal unit (such as photographing unit, single anti-) etc. of shoot function.Preferably, this mobile terminal can be the hardware device that mobile phone, panel computer etc. have various operating system.
As it is shown in figure 1, the method that this control scene photograph Live Photo generates may include that
S110, when shooting under electronic equipment is in scene photograph Live Photo pattern, carries out the record of video image, and target scene is carried out photograph taking target scene.
It should be noted that the method that the control scene photograph Live Photo of the embodiment of the present invention generates can be applicable to electronic equipment, this electronic equipment can have the shoot function of scene photograph Live Photo pattern.Such as, as a example by the mobile terminal with IOS (a kind of Mobile operating system developed by Apple) of Apple's research and development, when this mobile terminal is under Live Photo pattern, one section of dynamic video of 1.5 seconds is recorded before and after photograph taking, after on the photo photographed, length clicks user, this photo will play dynamic effect automatically.
That is, when detecting that user is shot by electronic equipment, can first detect the most whether this electronic equipment is in Live Photo pattern, when detecting that this electronic equipment is under Live Photo pattern, and detect when target scene is shot by user by this Live Photo pattern, this target scene can be carried out the record of video image, and this target scene is carried out photograph taking.Such as, as a example by the mobile terminal with IOS that electronic equipment is researched and developed for Apple, when detect user Live Photo pattern open in the case of click on take pictures time, start target scene is taken pictures, and start the record video image to this target scene.
According to the video image that recorded, S120, judges whether target scene is dynamic scene.
Specifically, the video image that recorded can be carried out graphical analysis, to judge whether the number of the similar frame in this video image exceedes certain threshold value, the most then can determine that this target scene is not dynamic scene, if this target scene is static scene；If the number of the similar frame in this video image is not less than certain threshold value, then can determine that this target scene is dynamic scene.Wherein, can be regarded as can be movable and have the scene of dynamic effect for dynamic scene.Wherein, it is judged that whether target scene is the description that the process that implements of dynamic scene can be found in subsequent embodiment.
S130, if judging that target scene is dynamic scene according to the video image that recorded, then retains video image and the photo of target scene photographed.
That is, when judging that this target scene is dynamic scene according to the video image that recorded, the photo of video image and the target scene photographed can be retained, so that user is when checking this photo by predetermined registration operation, it can be seen that the dynamic effect of this photo, such as the dynamic variable condition in this target scene a period of time reducible.Being appreciated that this video image can be made up of multiple still images, wherein, the file format of this video image can be but be not limited to MOV form etc..
According to the video image that recorded, S140, if judging that target scene not as dynamic scene, is then deleted video image, and retained the photo of the target scene photographed.
Specifically, when judging that this target scene is not as dynamic scene according to the video image that recorded, if this target scene is static scene (change the most over time, the scene that this picture is not changed in) time, the video image that recorded can be deleted, only retain the photo of the target scene photographed.It is appreciated that, the file carrying out shooting by this Live Photo pattern at present and generate is in addition to photo, also there is a video image, and when this target scene is static scene, under this Live Photo pattern in the video image of shooting picture also will not change over time and change, cause this video image that recorded not make much sense, therefore, this video image can be deleted, only retain the photo of this target scene itself.
Thus, when the method that the control scene photograph Live Photo of the embodiment of the present invention generates shoots under electronic equipment is in Live Photo pattern, can be by dynamically detecting whether this target scene is dynamic scene, to guarantee to generate the photo of significant Live Photo, i.e. at least wanting the photo that can move, the video image that otherwise recorded is nonsensical.
The method that control scene photograph Live Photo according to embodiments of the present invention generates, when shooting under electronic equipment is in scene photograph Live Photo pattern, target scene is carried out the record of video image, and target scene is carried out photograph taking, afterwards, can judge whether target scene is dynamic scene according to the video image that recorded, if, then retain video image and the photo of target scene photographed, otherwise delete video image, only retain the photo of the target scene photographed.I.e. by whether there occurs image change in detecting the time period under Live Photo pattern, to judge that whether target scene is as dynamic scene, and control video image and the generation of photo files under Live Photo pattern by judged result, the while of to ensure that the Live Photo of output every time is all substantial, the video also making picture still there is no need to record, save memory space and time time user checks photo, improve Consumer's Experience.
Fig. 2 is the flow chart of the method that the control scene photograph Live Photo according to one specific embodiment of the present invention generates.As in figure 2 it is shown, the method that this control scene photograph Live Photo generates may include that
S210, when shooting under electronic equipment is in scene photograph Live Photo pattern, carries out the record of video image, and target scene is carried out photograph taking target scene.
S220, determines the record time span of video image, and according to pre-conditioned, record time span is divided into multiple time period.
Wherein, in one embodiment of the invention, this pre-conditioned frame per second that may include but be not limited to video image and the hardware handles level etc. of electronic equipment.
Specifically, when recorded video image, can first determine the record time span of this video image, and according to pre-conditioned, this record time span being divided into multiple t time period t.It is to say, the length of this time period t can determine according to the hardware handles level of the frame per second of video image and electronic equipment.Such as, the frame per second of this video image is many and if the hardware handles level height of electronic equipment, then the length of this time period t can be smaller, more accurate to ensure the testing result of similar frame.
S230, for the i-th time period, it is judged that the first frame corresponding to the start time of i-th time period is the most similar to the second frame corresponding to the end time of i-th time period.
Specifically, during per elapsed time section t, the similarity of the frame corresponding to the start time of current slot t and the frame corresponding to finish time of current slot t can be contrasted.
Specifically, in one embodiment of the invention, the process that implements contrasted to the similar frame of the second frame corresponding to the end time in current slot for the first frame corresponding to start time in current slot can be as follows: first can obtain pixel and the pixel of the second frame of the first frame from video image, afterwards, the Similarity value of the pixel of the first frame and the pixel of the second frame can be calculated, and judge that whether Similarity value is more than or equal to the second predetermined threshold value, if Similarity value is less than the second predetermined threshold value, then judge that the first frame and the second frame are dissimilar；If Similarity value is more than or equal to the second predetermined threshold value, then judge that the first frame and the second frame are similar.
It is to say, when the similarity of the pixel corresponding to the first frame and the second frame is more than the second predetermined threshold value, it is believed that the change of this first frame and the second frame is little, i.e. it is believed that this two frame is similar frame.Wherein, this second predetermined threshold value can set according to practical situation.
In an embodiment of the present invention, the pixel of above-mentioned calculating the first frame can be as follows with the process that implements of the Similarity value of the pixel of the second frame: removable first frame is so that the location of pixels of the first frame at least partly overlaps with the location of pixels of the second frame aligns, and calculates the Similarity value of the pixel of the first frame and the pixel of the second frame according to the location of pixels alignd that at least partly overlaps.
That is, when the similar frame of the first frame and the second frame is compared, this first frame can be made to move vertically and horizontally by mobile first frame, align so that the location of pixels of this first frame at least partly overlaps with the location of pixels of the second frame, afterwards, the situation about aliging that at least partly can overlap according to this calculates the Similarity value of the pixel of the first frame and the pixel of the second frame.Thus, make two frames overlap by the way of alignment on some location of pixels by transportable frame, can quickly carry out the contrast of similar frame, such that it is able to save the reduced time, and reduce power consumption.
S240, if the first frame and the second frame are similar, then add up the number of similar frame, and determines whether that whether the number of similar frame is more than or equal to the first predetermined threshold value.
Specifically, when judging the first frame and the second frame is similar, the counting of similar frame can be added 1 to add up the number of current similar frame, and judge whether the number of this current similar frame exceedes certain numerical value (the first predetermined threshold value described above).Wherein, this first predetermined threshold value can be to set according to practical situation.
S250, if the number of similar frame more than or equal to the first predetermined threshold value, then judges that target scene, not as dynamic scene, and performs step S270.
S260, if the number of similar frame less than the first predetermined threshold value, then judges that target scene, as dynamic scene, and performs step S280.
S270, deletes video image, and retains the photo of the target scene photographed.
S280, retains video image and the photo of target scene photographed.
S290, if the first frame and the second frame are dissimilar, then according to the time period of selecting of default rule saltatory, and judges that the 3rd frame corresponding to start time of time period selected is the most similar to the 4th frame corresponding to the finish time of the time period selected.
Wherein, in an embodiment of the present invention, this default rule can be the rule of Fibonacci sequence.Fibonacci sequence is also called Fibonacci sequence, is defined as such ordered series of numbers: 0,1,1,2,3,5,8,13,21,34,55,89,144 ....
Such as, when judging the first frame and the second frame dissmilarity, according to the time period of selecting of Fibonacci sequence rule saltatory as this in 1* time period t, 3* time period t, 5* time period t, and can judge that the 3rd frame corresponding to start time of time period t selected is the most similar to the 4th frame corresponding to the finish time of the time period t selected.Wherein, the similarity comparison of the 3rd frame and the 4th frame can be found in the description of similarity comparison of above-mentioned first frame and the second frame.Do not repeat them here.
That is, when the first frame in determining current slot t and the second frame dissmilarity, can elongate by detection Cycle Length, saltatory can select time period t from remaining time period t, to carry out similar frame contrast, i.e. saltatory, remaining video image is carried out similar frame detection backward.It is appreciated that when judging the 3rd frame and the 4th frame dissmilarity, the interruption of saltatory can be widened, so can reduce amount of calculation, it is also possible to accelerate the versus speed of similar frame, power consumption can also be reduced simultaneously.
S2100, if the 3rd frame and the 4th frame are similar, exit the similar frame contrast selecting the time period according to default rule saltatory, and perform to judge the step that first frame corresponding to start time of i-th time period is the most similar to the second frame corresponding to the end time of i-th time period, remaining video image to be carried out similar frame contrast.
Specifically, when judging that the 3rd frame and the 4th frame are similar, the similar frame contrast selecting the time period according to default rule saltatory can be exited, i.e. carry out similar frame contrast according further to time period t one by one, i.e. return step S230 to continue to judge the first frame and the similarity comparison of the second frame in section t remaining time, to realize remaining video image is carried out similar frame contrast, until the similar frame of video image has contrasted, or the number of the similar frame of this video image is more than or equal to till the first predetermined threshold value.
