Wherein, first quality assessment result include the first image first exposure balance factor, the first pattern distortion because At least one of in the sub and the first distortion of image factor.

Optionally, the first pattern distortion factor can obtain by the following method: for the straight line occurred in the first image Type target calculates the corresponding curvature of the target, then obtains the first pattern distortion factor further according to the curvature.

Optionally, the first exposure balance factor can obtain by the following method: terminal device obtains the mistake of the first image The first accounting L1 of dark pixel is exposed and/or crossed, and according to first accounting L1, obtains the first exposure balance factor.

Wherein, the first accounting L1 can be only the accounting of the overexposure pixel of the first image, be also possible to accounting for for dark pixel Than can also be overexposure and cross total accounting of dark pixel, the present invention is not especially limit this.

It is understood that excessively dark pixel portion is in the first image if the width of the first image and high respectively w and hExcessively bright pixel portion is in first imageIllustratively, if the first accounting L1 is overexposure and crosses always accounting for for dark pixel Than then L1 can pass through formulaIt is calculated.

Optionally, the first distortion of image factor can obtain by the following method: terminal device obtains the of the first image One pitch angle.If first pitch angle is less than or equal to first threshold, the first distortion of image factor is arranged terminal device For the first preset value.If first pitch angle is greater than first threshold, in first facial of the terminal device according to the first image Lower ratioFirst nose ratioWith the first lip ratioAt least one of in, obtain the first distortion of image The value of the factor.

Wherein, the first pitch angle can be when first image includes figure information, the pitch angle of the figure information Degree.

It is understood that first preset value can be 0, it is also possible to infinitely great or infinitesimal, can also be other Numerical value, the present invention is not especially limit this.

Wherein, ratio above and below first facialFor in first image, the distance L11 of place between the eyebrows to nose lower boundary and Nose lower boundary to chin boundary distance L12 ratio；

First nose ratioFor nasal area area in first image entire portrait area area accounting；

First lip ratioFor lip region area in first image entire portrait area area accounting.

It is understood that the value of the first distortion of image factor can directly be first facial ratio up and down First nose ratioWith the first lip ratioIn a certain item value, be also possible to in them it is one or more into The value that row obtains after calculating, the present invention is not especially limit this.

Optionally, which can be the first facial to first image or more ratio The outer ratio of first noseWith ratio outside the first lipIn one or more be weighted and averaged acquire Value.

It is understood that in embodiments of the present invention, the first pattern distortion factor, the can also be obtained with other methods One exposure balance factor and the first distortion of image factor, the present invention is not especially limit this.

It is understood that the first quality assessment result can be the first exposure if first image includes figure information Any one in light balance factor, the first pattern distortion factor and the first distortion of image factor three, is also possible to wherein appoint The combination of meaning two, can also be three common combinations, the present invention is not especially limit this.

If first image does not include figure information, the first quality assessment result can be the first exposure balance factor and Any one in the first pattern distortion factor two, is also possible to two combinations, and the embodiment of the present invention is not made this specifically It limits.

Optionally, the first imaging effect can be the first quality assessment result, be also possible to according to first quality evaluation As a result the imaging parameters being calculated.The present invention is not especially limit this.

Optionally, can using 0.4,0.3 and 0.3 as first exposure balance factor, the first pattern distortion factor and The weight of the first distortion of image factor, to the first of the first image the exposure balance factor, the first pattern distortion factor and the first The distortion of image factor is weighted and averaged, and obtains imaging parameters as the first imaging effect.

If the first imaging effect of S303, first image is less than or equal to third threshold value, terminal device is by the camera It fixes or adjusts to first position, and show or store the second image that the camera is shot in the first position.

Optionally, terminal device first can fix or adjust the camera, then show or store the second image；It can also be first The camera is fixed or adjusted again to display or the second image of storage；Also it may be performed simultaneously.The embodiment of the present invention does not make this to have Body limits.

It is understood that fixing or adjusting the camera to first position in the embodiment of the present invention, can be straight It connects and the camera is fixed on first position, be also possible to that the camera is first allowed to be moved to other positions, then adjust to first It sets, the present invention is not especially limit this.
