In some embodiments, after mobile phone enters slow-motion screening-mode, if the shooting of mobile phone acquisition shooting picture Frame per second is higher (being greater than 120fps), then can trigger mobile phone and start to execute following step S302-S307, allow mobile phone pre- It lookes in interface 401 and removes the film flicker phenomenon occurred in viewfinder window in real time.

In further embodiments, after mobile phone enters slow-motion screening-mode, mobile phone can be executed detecting user After recording operation (for example, clicking above-mentioned recording button 404), starts to execute following step S302-S307, allow mobile phone slow The film flicker phenomenon occurred in viewfinder window is removed in the shooting process of action video in real time.

In addition, following embodiment is illustrated with shooting the usage scenario of slow motion video.It is understood that working as When mobile phone uses higher shooting frame rate (shooting frame rate for being greater than 120fps) recorded video, under mobile phone can be by executing Step S302-S307 is stated, the film flicker phenomenon being likely to occur in shooting picture is removed.

S302, in response to above-mentioned recording operation, mobile phone start obtain the collected each frame shooting picture of camera.

The citing of the recording button 404 in Fig. 5 in preview interface 401 is still clicked with user, mobile phone can respond user's click should The operation of button 404 is recorded, calls camera to acquire each frame shooting picture according to preset shooting frame rate, starts to record this Slow motion video.With the passage of recording time, the frame number of the collected shooting picture of mobile phone will be built up, and mobile phone is based on this A little shooting pictures can finally form the slow motion video that this slow motion obtains.

With preset shooting frame rate be 960fps citing, detect user is clicked under slow-motion screening-mode record by After button 404, mobile phone can acquire each frame shooting picture using camera according to the speed of every 1 second 960 frame shooting pictures of acquisition.And And mobile phone can carry out image procossing to collected shooting picture by the following method, and by the shooting picture after image procossing It is shown in the viewfinder window at shooting interface.

In some embodiments, mobile phone can carry out at image collected each frame shooting picture by the following method Reason.Alternatively, since the frame number of the collected shooting picture of mobile phone is more, and shooting picture of the actual displayed in viewfinder window is It is extracted from the collected shooting picture of mobile phone.For example, mobile phone can acquire shooting picture according to the shooting frame rate of 960fps, but Practical mobile phone can carry out pumping frame from the shooting picture of acquisition according to the display frame rate of 60fps and show.In further embodiments, hand Machine can carry out by the following method image procossing to each frame shooting picture to be shown, and the embodiment of the present application does not do this any Limitation.

S303, mobile phone are determined in current recording scene and are dodged with the presence or absence of picture according to the brightness of continuous N frame shooting picture Bright phenomenon, N are the integer greater than 1.

Mobile phone starts after recording this slow motion video, can obtain camera continuous N frame collected recently in real time and clap Take the photograph picture.Alternatively, while mobile phone acquires each frame shooting picture, mobile phone can also according to certain display frame rate (such as 30fps or 60) fps extract nearest continuous N frame shooting picture from the shooting picture of acquisition, this N frame shooting picture is to wait The shooting picture being shown in shooting interface.

Mobile phone can be determined existing with the presence or absence of film flicker in current recording scene based on the brightness of above-mentioned N frame shooting picture As determining whether this N frame shooting picture occurs brightness fluctuation.If there is film flicker phenomenon, then mobile phone can continue to execute Following step S304-S306 removes the scintillation in shooting picture in real time.If there is no film flicker phenomenon, then mobile phone Can be by collected shooting picture real-time display in the viewfinder window at shooting interface, and continue according to existing video recording method Record this slow motion video.

Illustratively, as shown in fig. 6, mobile phone starts after recording this slow motion video, the 1st frame shooting picture is collected respectively Face, the 2nd frame shooting picture and the 3rd frame shooting picture.In turn, mobile phone can calculate separately the brightness Y1 of the 1st frame shooting picture, and the 2nd The brightness Y2 of the frame shooting picture and brightness Y3 of the 3rd frame shooting picture.

For calculating the brightness Y1 of the 1st frame shooting picture, mobile phone can be by preset color encryption algorithm, by the 1st frame Shooting picture is converted to the image 1 of yuv format.At this point, each pixel in image 1 can use Y (brightness), U (color Degree) and V (coloration) these three values indicate.In turn, mobile phone can calculate being averaged for the brightness of all pixels point in image 1 Value, which is the brightness Y1 of the 1st frame shooting picture.The embodiment of the present application does not do any restrictions to the unit of brightness.

Still as shown in fig. 6, after getting the brightness Y1-Y3 of the 1st the-the 3 frame shooting picture of frame, mobile phone can calculate brightness Y1, The variance F of brightness Y2 and brightness Y3.If variance F is greater than preset value, illustrate that the brightness of the 1st the-the 3 frame shooting picture of frame occurs Fluctuation, is most likely under the flashing scene of light, therefore, mobile phone can determine that there are picture sudden strains of a muscle in current recording scene at this time Bright phenomenon.

Correspondingly, illustrating the brightness ratio of the 1st the-the 3 frame shooting picture of frame if variance F is less than or equal to above-mentioned preset value More stable, therefore, mobile phone can determine that there is no film flicker phenomenons in current recording scene.At this point, mobile phone can continue to obtain 2nd the-the 4 frame shooting picture of frame, the 3rd the-the 5 frame shooting picture of frame ....In this way, mobile phone can according to the method described above, based on nearest The 3 frame shooting pictures got determine that current record whether there is film flicker phenomenon in scene in real time.

It should be noted that determining whether that there are picture sudden strains of a muscle according to above-mentioned the-the 3 frame shooting picture of 1st frame in mobile phone When bright phenomenon, above-mentioned the-the 3 frame shooting picture of 1st frame can be shown as recording by mobile phone in the viewfinder window at shooting interface in real time Picture.Since mobile phone has not determined out there are scintillation in shooting picture at this time, there are no to the 1st the-the 3 frame of frame for mobile phone The processing of shooting picture progress blink-off.So, in the 1st the-the 3 frame shooting picture of frame in slow motion video that mobile phone is recorded The phenomenon that will appear brightness fluctuation, but since the time is excessively of short duration, human eye is difficult to identify that the 1st the-the 3 frame shooting picture of frame In film flicker.

S304, if it exists scintillation, then after mobile phone collects X frame shooting picture, according to nearest M frame shooting picture The brightness of luminance mean value adjustment X frame shooting picture.

It wherein, include X frame shooting picture in above-mentioned M frame shooting picture.For example, X frame shooting picture can be nearest Last frame shooting picture in collected (or to be shown) M frame shooting picture.

Since the scintillation occurred in shooting picture is mainly since the fluctuation of brightness between each shooting picture causes , therefore, when the scintillation occurred in shooting picture, mobile phone can adjust the brightness of shooting picture, so that each shooting picture The brightness in face tends towards stability, to weaken or eliminate the scintillation occurred in shooting picture.

Still with photographed scene shown in fig. 6 citing, mobile phone is based on the 1st the-the 3 frame shooting picture of frame and determines that there is currently pictures After the scintillation of face, with the citing of the 4th frame shooting picture, as shown in fig. 7, mobile phone gets (the 4th frame shooting of the 4th frame shooting picture Picture is latest frame) after, the luminance mean value of nearest 4 frame shooting picture can be calculated.Illustratively, mobile phone can be according in step S303 The method calculates separately the brightness Y1 of the 1st frame shooting picture, the brightness Y2 of the 2nd frame shooting picture, the 3rd frame shooting picture The brightness Y4 of brightness Y3 and the 4th frame shooting picture.In turn, mobile phone can calculate brightness Y1, brightness Y2, brightness Y3 and brightness Y4 Average value P, which is the luminance mean value of nearest 4 frame shooting picture.

For example, the brightness Y4 of the 4th frame shooting picture is 105, the luminance mean value P of nearest 4 frame shooting picture is 110.So, In order to enable the brightness of each shooting picture tends towards stability, the brightness Y4 of the 4th frame shooting picture can be adjusted to by mobile phone from 105 110, i.e., it is the luminance mean value of nearest M frame shooting picture by the brightness adjustment of X frame shooting picture.

Illustratively, still to adjust the brightness Y4 citing of the 4th frame shooting picture, mobile phone can be to every in the 4th frame shooting picture The brightness of a pixel is multiplied by a regulation coefficient.When brightness Y4 is greater than above-mentioned luminance mean value, settable 0 < regulation coefficient < 1； When brightness Y4 is less than above-mentioned luminance mean value, settable regulation coefficient > 1.In this way, by adjusting each in the 4th frame shooting picture The brightness of pixel can adjust the brightness of entire 4th frame shooting picture.

Above-described embodiment is illustrated with the brightness for adjusting the 4th frame shooting picture, is still illustrated with X=4, when mobile phone obtains When getting the 5th frame shooting picture, mobile phone can continue according to the method described above according to (i.e. the 2nd the-the 5 frame of the frame bat of nearest 4 frame shooting picture Take the photograph picture) luminance mean value, adjust the 5th frame shooting picture brightness.

Similar, after mobile phone determines the scintillation occurred in shooting picture, shooting picture newest for each frame Its brightness can be adjusted according to the method described above, so that mobile phone can compensate for each frame shooting picture under the photographed scene for having light flash The brightness value in face makes the brightness of each shooting picture tend towards stability, and shows to weaken or eliminate the flashing occurred in shooting picture As.

In addition, X frame shooting picture adjusted can be made after mobile phone is adjusted the brightness of X frame shooting picture It is shown in the viewfinder window at shooting interface to record picture.Alternatively, mobile phone can also be to the X frame shooting picture after brightness adjustment Continue to execute step S305-S306.

X frame shooting picture after brightness adjustment is carried out image co-registration with nearest Y frame shooting picture by S305, mobile phone, Obtain X ' frame shooting picture.

In some embodiments, brightness fluctuation of the scintillation occurred in shooting picture not only with entire shooting picture has It closes, it is also related with brightness fluctuation subregional in the middle part of shooting picture.For example, the bat in continuous multiple frames shooting picture, in the A of region Content is taken the photograph to occur from bright to dark again from secretly to bright periodical brightness fluctuation, this causes to shoot picture when recording slow motion video The region A in face will appear scintillation.

In this regard, still with the citing of the 4th frame shooting picture, mobile phone has adjusted the 4th frame by step S304 and claps in step S305 After taking the photograph the brightness of picture, as shown in figure 8, the Y frame before the 4th frame shooting picture and the 4th frame shooting picture can be shot picture by mobile phone Face (such as the 1st-the 3 frame shooting picture of frame) carries out image co-registration, the 4th newly-generated frame shooting picture after being merged (i.e. the X ' frame shooting picture).

It illustratively, include a*b pixel in the 1st the-the 4 frame shooting picture of frame, each pixel all has correspondence Pixel value.When carrying out image co-registration, for each pixel, mobile phone can calculate the pixel and shoot in the 1st the-the 4 frame of frame The pixel value of the pixel in the average value of pixel value in picture, and using the average value as X ' frame shooting picture.For example, such as Shown in Fig. 8, citing is put with the upper left corner A ' of the 4th frame shooting picture newly-generated after fusion, mobile phone can calculate the 1st frame shooting picture A2 point in the upper left corner in middle upper left corner A1 point, the 2nd frame shooting picture, upper left corner A3 point and the shooting of the 4th frame in the 3rd frame shooting picture The pixel average of this 4 pixels of upper left corner A4 point in picture.In turn, which is the 4th frame shooting after merging The pixel value of corresponding A ' point in picture.

So, after image co-registration, the pixel value of each pixel is the picture in the 4th newly-generated frame shooting picture Pixel average of the vegetarian refreshments in continuous multiple frames, so that a certain region is in continuous multiple frames in the 4th frame shooting picture of decrease or elimination Between brightness fluctuation, further obviate the scintillation occurred in the 4th frame shooting picture.

Certainly, above-described embodiment be to generate the 4th new frame shooting picture by image co-registration and illustrate, it is subsequent, For shooting picture of each frame after brightness adjustment, fused shooting picture can be generated according to the method described above.For example, After mobile phone gets the 5th frame shooting picture, the 5th frame shooting picture can also be subjected to image with the 2nd the-the 4 frame shooting picture of frame and melted It closes, generates fused 5th frame shooting picture.At this point, when carrying out image co-registration the 4th frame shooting picture that uses can be it is above-mentioned The 4th frame shooting picture newly-generated after image co-registration.

If S306, X ' it include moving region in frame shooting picture, mobile phone uses the motor area in X frame shooting picture Replace the moving region in X ' frame shooting picture in domain.

Still with the citing of above-mentioned 4th frame shooting picture, after mobile phone generates the 4th new frame shooting picture by image co-registration, though The scintillation in shooting picture can be so eliminated, still, still as shown in figure 8, when the multiframe shooting picture for carrying out image co-registration In include movement object (such as personage 701) when, personage 701 can be generated in the 4th newly-generated frame shooting picture after fusion Ghost influences shooting effect.

So, in step S306, mobile phone can carry out the multiframe shooting picture of image co-registration in first detecting step S305 In whether include moving object.Image co-registration citing, hand are still carried out with the 4th frame shooting picture and the 1st the-the 3 frame shooting picture of frame Machine can be compared using the 4th frame shooting picture before fusion with the 1st the-the 3 frame shooting picture of frame respectively.

As shown in (a) in Fig. 9, mobile phone can compare each pixel in the 4th frame shooting picture and the 1st frame shooting picture Point, if the difference of pixel value of the pixel of same position in the 4th frame shooting picture and the 1st frame shooting picture is greater than threshold Value, then mobile phone is believed that the pixel is a pixel of moving object.For example, mobile phone may recognize that the 4th frame shooting picture In moving object 701 and the 1st frame shooting picture in moving object 702.

Similar, as shown in (b) in Fig. 9, by comparing each of the 4th frame shooting picture and the 2nd frame shooting picture Pixel, mobile phone may recognize that the moving object in moving object 701 and the 2nd frame shooting picture in the 4th frame shooting picture 703.As shown in (c) in Fig. 9, pass through each pixel in the 4th frame shooting picture of comparison and the 3rd frame shooting picture, mobile phone It may recognize that the moving object 704 in the moving object 701 and the 3rd frame shooting picture in the 4th frame shooting picture.

So, as shown in Figure 10, mobile phone is according to the moving object 701-704 identified in the 1st the-the 4 frame shooting picture of frame, The moving region 901 where moving object 701-704 is determined in the 4th frame shooting picture that can be newly-generated after fusion.In order to Eliminate the ghost in moving region 901, still as shown in Figure 10, mobile phone can from merge be taken off in preceding 4th frame shooting picture with it is above-mentioned Picture in the corresponding region 902 in moving region 901, and the 4th frame shooting picture after the picture replacement fusion in using area 902 Picture in middle moving region 901.Due to not having in region 902 corresponding with above-mentioned moving region 901 in the 4th frame shooting picture There is the ghost of moving object, therefore behind the replacement of using area 902 moving region 901, fused 4th frame shooting picture can be eliminated In ghost.At this point, both having eliminated the scintillation in shooting picture in the 4th frame shooting picture of mobile phone final output, simultaneously Also eliminate the ghost phenomena in shooting picture.

It is similar, mobile phone by image co-registration generate the 5th new frame shooting picture, the 6th frame shooting picture ... and When X frame shooting picture, the ghost phenomena in shooting picture can be eliminated according to the method described above.

Certainly, if mobile phone detect carry out image co-registration multiframe shooting picture in do not include moving object, illustrate this When X ' frame shooting picture in do not include moving region, i.e., there is no ghost in X ' frame shooting picture.So, mobile phone is merged After newly-generated X afterwards ' frame shooting picture, following step S307 can be directly executed, no longer needs to execute step S306.

S307, mobile phone show X in shooting interface ' frame shooting picture.

Still with the citing of the 4th frame shooting picture, under the photographed scene there are scintillation, mobile phone is by executing above-mentioned steps S304-S306 can remove the scintillation in the 4th frame shooting picture, and obtaining the 4th newly-generated frame shooting picture, (i.e. X ' frame is clapped Take the photograph picture).So, in step S307, as shown in figure 11, after mobile phone obtains the 4th newly-generated frame shooting picture, can in real time by The 4th newly-generated frame shooting picture is shown in the viewfinder window at shooting interface 1002 as picture 1001 is recorded.

Equally, the subsequent mobile phone shooting picture to be shown to each frame can remove in shooting picture according to the method described above Scintillation, and the viewfinder window by X ' frame shooting picture real-time display newly-generated after removal flashing at shooting interface 1002 It is interior.

In this way, mobile phone is presented to user when user watches the slow motion video recorded in shooting interface 1002 Shooting picture is so that user is not obviously experienced the flashing in shooting picture existing by blink-off treated shooting picture As improving high frame per second and recording the shooting quality of video and the usage experience of user under scene.

In some embodiments, after detecting that user inputs recording operation under slow motion screening-mode, mobile phone can be according to Preset shooting frame rate (such as 960fps) acquires each frame shooting picture.

After collecting these shooting pictures, one side mobile phone can be according to preset display frame rate (such as 60fps) from acquisition Shooting picture in extract corresponding shooting picture.In turn, mobile phone can be removed according to method described in above-mentioned steps S303-S307 The scintillation in each frame shooting picture being extracted, and each frame shooting picture real-time display after blink-off is being shot In interface 1002.

On the other hand, mobile phone can be reserved for collected each frame shooting picture in recording process.If detecting that user is defeated Enter to terminate the operation recorded, for example, user clicks the operation of button 401 in shooting interface 1002, then mobile phone can be by recording process In collected all shooting pictures saved with the format of slow motion video.With when a length of 3s recording time citing, detect After the operation that user's end of input is recorded, mobile phone collects 2880 frames (960fps*3) shooting altogether in this 3 seconds recording time Picture.In turn, mobile phone can go collected each frame shooting picture according to method described in above-mentioned steps S303-S307 Flashing processing.Subsequent, each shooting picture after blink-off can be encoded to slow motion of one section of duration greater than 3 seconds and regarded by mobile phone Frequently, and the slow motion video is saved.In this way, when user is subsequent the slow motion video is opened in photograph album when, mobile phone can be to user The each frame shooting picture for having already passed through blink-off processing is played, to improve the shooting matter that high frame per second records video under scene Amount.

That is, mobile phone can only be treated aobvious in preview and shooting process under the higher recording scene of filming frequency The shooting picture shown carries out blink-off processing, and does not have in real time carry out at blink-off collected each frame shooting picture Reason, can not only remove film flicker phenomenon, while improving mobile phone in preview and shooting process in preview and shooting process In treatment effeciency and calculating speed.

In further embodiments, mobile phone collects each frame according to preset shooting frame rate (such as 240fps) and shoots picture Behind face, in real time collected each frame shooting picture can dodge according to method described in above-mentioned steps S303-S307 Bright processing.In turn, mobile phone can extract corresponding shooting picture from the shooting picture after blink-off and be shown in shooting interface 1002 In.Also, after detecting the operation that user's end of input is recorded, each shooting picture after blink-off can be encoded to one by mobile phone Section slow motion video is saved.

So, since mobile phone has carried out blink-off processing to collected each frame shooting picture in real time, Therefore, mobile phone carries out shooting picture without executing above-mentioned steps S303-S307 again when generating this slow motion video Blink-off processing, so as to reduce the calculation amount during mobile phone records a slow motion video.

It is to start recording slow motion video under lamplight scene with user to illustrate in above-described embodiment, it is possible to understand that , mobile phone is when using high frame per second recorded video, if detecting that there are pictures in current recording scene at any time Scintillation, mobile phone can remove the scintillation in collected shooting picture according to the method described above.

Illustratively, mobile phone can enter slow motion screening-mode under lamplight scene.

After mobile phone enters slow motion screening-mode, although starting to record slow motion video not yet, mobile phone is needed pre- Look at interface viewfinder window in show preview screen.Therefore, mobile phone can start according to preset filming frequency (such as 480fps) acquire each frame shooting picture.In turn, mobile phone can be according to the display frame rate of 60fps from collected shooting picture Extract shooting picture to be shown.

As shown in figure 12, indoors under lamplight scene, before mobile phone is drawn into after N frame shooting picture, as described in step S303, Mobile phone can be determined in current preview scene according to the brightness of preceding N frame shooting picture with the presence or absence of film flicker phenomenon.It is exemplary , still as shown in figure 12, if larger fluctuation occurs in the brightness of preceding N frame shooting picture, mobile phone can determine that current preview There are film flicker phenomenons in scene.Also, this preceding N frame shooting picture can be shown the viewfinder window in preview screen by mobile phone In.

In turn, since the N+1 frame shooting picture being drawn into, still as shown in figure 12, mobile phone can be according to above-mentioned steps Method described in S304-S307, to be drawn into each frame shooting picture (such as N+1 frame shooting picture, N+2 frame shoot Picture ...) blink-off processing is carried out, and each frame shooting picture after removal flashing is shown in real time in preview interface In.In this way, the brightness by blink-off treated each frame shooting picture is gradually stable in a certain value.That is, Before recording slow motion video, the scintillation under lamplight scene when preview shooting picture is suppressed, and user is in preview interface The shooting picture watched is not in apparent scintillation.

Subsequent, user, which can switch to mobile phone under the scene of no light flash, starts recorded video.

As shown in (a)-(c) in Figure 13, under scene of the outdoor without light, it is defeated in preview interface that mobile phone responds user The recording operation entered can start to record slow motion video.For example, mobile phone can acquire each frame according to the filming frequency of 480fps Shooting picture, also, mobile phone can extract K frame to be shown from collected shooting picture according to the display frame rate of 60fps and clap Take the photograph picture.Meanwhile as described in step S303, mobile phone can determine currently in real time according to the N frame shooting picture being drawn into recently It records and whether there is film flicker phenomenon in scene.

Illustratively, mobile phone can calculate separately the brightness of every frame shooting picture in K frame shooting picture.Due to current bat Taking the photograph does not have light flash in scene, therefore the brightness of every frame shooting picture tends towards stability.For example, such as (a)-(c) institute in Figure 13 Show, the brightness value of above-mentioned K frame shooting picture is stablized 95 or so.So, the variance of the brightness of nearest K frame shooting picture also phase To smaller, in turn, mobile phone can determine that there is no film flicker phenomenons in current recording scene.At this point, mobile phone is no longer needed to upper It states K frame shooting picture and carries out blink-off processing, can directly be shown using each frame shooting picture being drawn into as picture is recorded It shoots in interface, user will not experience scintillation when watching the video recorded in shooting interface.

Subsequent, user can be by the recording scene of slow motion video from the above-mentioned outdoor scene switching without light to indoor light Scene continues to record.After entering the room lamplight scene, mobile phone can continue to acquire each frame shooting according to the filming frequency of 480fps Picture, and shooting picture to be shown is extracted according to the display frame rate of 60fps.

As shown in (a)-(c) in Figure 14, K+1 frame shooting picture, the bat of K+2 frame can be drawn by entering the room rear mobile phone Take the photograph picture and K+3 frame shooting picture.Since indoor light is flashed with the frequency of alternating current, K+1 frame is clapped The brightness for taking the photograph picture, K+2 frame shooting picture and K+3 frame shooting picture will appear fluctuation.For example, such as (a)-in Figure 14 (c) shown in, the brightness Y (k+1) that mobile phone can calculate K+1 frame shooting picture is 110, the brightness Y (k of K+2 frame shooting picture It+2) is 120, the brightness Y (k+3) of K+3 frame shooting picture is 116.In turn, still as described in step S303, mobile phone is according to this company The brightness of continuous 3 frame shooting pictures can determine that there are film flicker phenomenons in current recording scene.

Meanwhile the K+1 frame shooting picture being drawn into, K+2 frame shooting picture and K+3 frame can be shot picture by mobile phone Face is shown in real time in shooting interface.Mobile phone carries out blink-off to K+1 frame the-the K+3 frame shooting picture not yet at this time Processing.So, it also will appear brightness fluctuation in K+1 frame the-the K+3 frame shooting picture in slow motion video that mobile phone is recorded Phenomenon, but since the time is excessively of short duration, human eye is difficult to identify that the film flicker in shooting picture at this time.

In turn, it as shown in (a)-(c) in Figure 15, records in scene when determining there are after film flicker phenomenon, mobile phone can According to method described in above-mentioned steps S304-S307, to be drawn into each frame shooting picture (such as K+4 frame shooting picture, K+5 frame shooting picture ...) blink-off processing is carried out, and each frame shooting picture after removal flashing is shown in real time In shooting interface, user will not obviously experience the scintillation in shooting picture at this time.
