Speed, the kinematic parameter that gyroscope detects are the angle of electronic equipment.
Step 202: obtaining the parameter information of target image, which includes aperture time and kinematic parameter, is based on
The parameter information of target image determines the picture quality of target image.
Wherein, since the parameter information of target image not only may include aperture time and kinematic parameter, can also include
The multiple parameters such as aperture, focal length and ISO sensitivity, therefore, electronic equipment can be based on different parameter informations, to determine target
The picture quality of image.In embodiments of the present invention, parameter information of the electronic equipment based on target image, determines target image
The method of picture quality may include following two, as described below.
The first, when parameter information includes aperture time and kinematic parameter, parameter of the electronic equipment based on target image
Information determines that the operation of the picture quality of target image can be with are as follows: when target image aperture time greatly at fixed time and mesh
When the kinematic parameter of logo image is greater than specified threshold, determine that the image parameter of target image is fuzzy.

Aperture time, kinematic parameter, aperture, focal length and the ISO sensitivity of logo image, determine the fuzziness of target image, target image
Fuzziness be the aperture time of target image, kinematic parameter, aperture, focal length and ISO sensitivity weighted value；Work as target image
Fuzziness be greater than Fuzzy Threshold when, determine that the picture quality of target image is fuzzy.
It wherein, can be by aperture time, kinematic parameter, aperture, focal length and ISO when determining the fuzziness of target image
Each parameter weight ratio corresponding with each parameter is multiplied in sensitivity, and by five product additions of multiplication, to obtain mesh
The synthesis fuzziness of logo image.
Add it should be noted that each parameter is corresponding in aperture time, kinematic parameter, aperture, focal length and ISO sensitivity
Power ratio is set in advance, for example, the weight ratio of aperture time is 0.1, the weight ratio of kinematic parameter is 0.3, aperture,
Focal length and the weight ratio of ISO sensitivity are 0.2 etc., and the present invention is not especially limit this.In addition, Fuzzy Threshold
It can also be arranged in advance, for example, Fuzzy Threshold is 20,30 etc., the embodiment of the present invention is not limited this equally.

Value be greater than the first luminance threshold when, determine target image picture quality be it is over-exposed, when the average brightness of target image
When less than the second luminance threshold, determine the picture quality of target image for under-exposure.
It can also be the image in photograph album since target image can be not only the image of electronic equipment shooting, and photograph album
In image may obtain less than parameter informations such as aperture time or kinematic parameters, therefore, when obtain fall short image ginseng
When number information, electronic equipment can determine the quality of target image by step 203.
Wherein, when electronic equipment obtains the grey level histogram of target image, which can be thumbnail, due to
The grey level histogram of original image and thumbnail difference is smaller, and the clarity of thumbnail is lower, therefore, using thumbnail as mesh
Logo image can save the time, improve speed.
It should be noted that the first luminance threshold and the second luminance threshold can be arranged in advance, and the first luminance threshold is big
In the second luminance threshold, for example, the first luminance threshold is 180,190, the second luminance threshold is 90,100 etc., the embodiment of the present invention
This is not construed as limiting.
Step 204: when the picture quality of target image meets any preset condition, recommending target image, wherein pre-
If condition includes fuzzy, over-exposed and under-exposed.
By above-mentioned steps 201-203, however, it is determined that target image picture quality meet it is fuzzy, over-exposed or exposure
Any preset condition in light deficiency, target image is recommended user by electronic equipment, so that user screens and deletes.
Further, electronic equipment can also be according to the final screening of user and deletion as a result, to relating in above-mentioned steps 202
And to aperture time, kinematic parameter, aperture, the corresponding weight ratio of each parameter is adjusted in focal length and ISO sensitivity, with
Make the target image recommended closer to the requirement of user.
Wherein, since aperture time, kinematic parameter, focal length or ISO sensitivity are bigger, target image is more easy to appear mould
Paste, aperture is smaller, target image be more easy to appear it is fuzzy, therefore, can with based on the principle that aperture time, movement join
The corresponding weight ratio of each parameter is adjusted in number, aperture, focal length and ISO sensitivity.
For example, when the quantity for the target image recommended is more, and when quantity that user finally deletes is smaller, can reduce fast
Door time, kinematic parameter, focal length or the corresponding weight ratio of ISO sensitivity increase the corresponding weight ratio of aperture, to reduce
The quantity of the target image of recommendation, to make the target image recommended closer to the requirement of user.
