Embodiment
Below in conjunction with accompanying drawing, the stabilization photographic method of the embodiment of the present invention, device and mobile terminal are described in detail.
Embodiment one
Fig. 1 is the schematic flow sheet of a stabilization photographic method embodiment provided by the invention. The stabilization photographic method of the embodiment of the present invention can be applicable to various to have in the mobile terminal (such as mobile phone, panel computer etc.) of camera function. As shown in Figure 1, the stabilization photographic method of the embodiment of the present invention specifically can comprise:
S101, when receiving photographing instruction, the first photo under pre-multiple normal exposure parameters of shooting and the 2nd photo under an instantaneous exposure parameter.
Concrete, after camera applications is opened, beginning of taking pictures, user presses shutter, sends photographing instruction after locking automatic exposure/auto-focusing. Exposure parameter comprises exposure value, time shutter and gain etc. The exposure parameter of adjustment under normal exposure parameter and auto exposure mode, exposure parameter corresponding when namely instantaneous exposure parameter reduces the time shutter based on normal exposure parameter when exposure value is constant, can artificially be arranged.
S102, selects the first photo that in multiple first photos, sharpness is the highest as alternative photo.
Concrete, from normal exposure parameter, multiple first photos of shooting select that the highest photo of sharpness as alternative photo.
S103, if alternative photo is greater than relative clarity threshold relative to the relative sharpness of the 2nd photo, then exports alternative photo.
Concrete, assume that relative clarity threshold is 0.8, alternative photo is 0.9 relative to the relative sharpness of the 2nd photo of shooting under instantaneous exposure parameter, then alternative photo is greater than relative clarity threshold 0.8 relative to the relative sharpness 0.9 of the 2nd photo, being exported as last achievement photo by alternative photo, user can preserve or delete the photo of output as required.
S104, if the relative sharpness of alternative photo is equal to or less than relative clarity threshold, then exports the 2nd photo.
Concrete, assume that relative clarity threshold is 0.8, alternative photo is 0.7 relative to the relative sharpness of the 2nd photo of shooting under instantaneous exposure parameter, then alternative photo is less than relative clarity threshold 0.8 relative to the relative sharpness 0.7 of the 2nd photo, being exported as last achievement photo by 2nd photo of shooting under instantaneous exposure parameter, user can preserve or delete the photo of output as required.
Due under same jitter conditions, time shutter, more short stabilization effect was more good, sharpness is more good, but the noise jamming in shooting process is more big, accuracy is more low, therefore when the sharpness of the 2nd photo of the sharpness comparatively shooting under the instantaneous exposure parameter of stabilization better effects if of the alternative photo of shooting under normal exposure parameter, for avoiding noise jamming, improve accuracy, select alternative photo to export as last achievement photo; When the sharpness of alternative photo of shooting under normal exposure parameter is with, when under the instantaneous exposure parameter of stabilization better effects if, the sharpness of the 2nd photo of shooting differs bigger, the 2nd photo selecting sharpness higher exports as last achievement photo. Optionally, before exporting the 2nd photo, the 2nd photo can be carried out noise reduction process, avoid noise jamming, it is to increase accuracy. Aforesaid method selectivity is adopted to export alternative photo or the 2nd photo so that the photo stabilization effect of output is ideal, and sharpness is better.

By judging the steady state of mobile terminal, when the steady state of mobile terminal be in steady state threshold range (steady state is neither too stable only in instability) time, perform pre-shooting operation and follow-up stabilization treating processes. When the steady state of mobile terminal is too stablized, such as, when using trivet fixed cellular terminal, almost there is not shake situation, therefore without the need to stabilization process, direct normal photographing, avoids increasing unnecessary shooting time. When the steady state of mobile terminal is too unstable, such as, when mobile terminal rocks excessive, owing to shake is too obvious, beyond the limit of power of stabilization of the present invention process, therefore also process without the need to stabilization, direct normal photographing, avoids carrying out insignificant stabilization treating processes, now can also rock by prompting mobile terminal on a user interface.
Further, step S201 judging, the detailed process of the steady state of mobile terminal can comprise: the steady state data obtaining mobile terminal; The stability numerical value of mobile terminal is calculated according to steady state data; The steady state of mobile terminal is judged according to stability numerical value.

Between upon exposure too short time, such as, when the time shutter is less than 1/100 second, shake situation is negligible, and therefore without the need to stabilization process, direct normal photographing, avoids the unnecessary shooting time of increase. When crossing long between upon exposure, such as, when the time shutter is greater than 1/30 second, due to the limit of power processed beyond stabilization of the present invention, therefore also without the need to stabilization process, direct normal photographing, avoids carrying out insignificant stabilization treating processes.

S205, if alternative photo is greater than relative clarity threshold relative to the relative sharpness of the 2nd photo, then exports alternative photo.
Concrete, the detailed process of step S205 can the associated description in step S103 in embodiment shown in Figure 1, repeat no more herein.
