The flow chart of a kind of image recommendation method that Fig. 2 provides for the embodiment of the present invention, the method is applied in electronic equipment, and as shown in Figure 2, this image recommendation method comprises the following steps:
Step 201: obtain target image.
Wherein, obtain target image and comprise the image obtaining electronic equipment current shooting, or receive the instruction of user's input, obtain the image in photograph album according to instruction.
Particularly, when electronic equipment obtains the image of current shooting, electronic equipment can detect the image whether having current shooting, and when the image of current shooting being detected, electronic equipment directly can obtain the image of current shooting; Or when the image of current shooting being detected, electronic equipment display reminding information, makes user select whether to obtain the image of current shooting, if user confirms to select, then obtain the image of current shooting.Such as, information as shown in Figure 3, if user selects to be then obtain the image of current shooting, if user selects no, does not then obtain the image of current shooting.
When electronic equipment receives the instruction of user's input, when obtaining the image in photograph album according to instruction, user can input instruction by pre-set button, and selects the image in photograph album.Wherein, when selecting the image in photograph album, not only can select one or more photograph album, also can select in a photograph album or multiple images.Such as, as shown in Figure 4, user by clicking pre-set button input instruction, and selects multiple images in photograph album, and after having selected, electronic equipment obtains the image in photograph album.
It should be noted that, it is exemplary for being inputted for obtaining the instruction of image in photograph album by pre-set button, certainly, user also can input instruction by assigned operation, such as, assigned operation can be slide, whipping operation etc., and the embodiment of the present invention does not limit this.
Further, before acquisition target image, when in the process of electronic equipment at photographic images, electronic equipment not only can obtain the essential information of the image of current shooting, such as, shooting time, spot for photography, aperture time, aperture, focal length and International Organization for standardization's photosensitivity (English: InternationalStandardizationOrganizationPhotosensibility, be called for short: ISO photosensitivity) etc., the kinematic parameter of current taken image can also be obtained, and this kinematic parameter is preserved, such as, a self-defined EXIF item in the fileinfo of the image of current shooting, kinematic parameter is kept in EXIF, certainly, also can kinematic parameter be kept in the fileinfo of the image of current shooting with other any form, the embodiment of the present invention does not limit this.
It should be noted that, this kinematic parameter in aperture time, detects by the motion sensor of electronic equipment the parameter obtained, this motion sensor can be acceleration transducer, gyroscope, or other is for detecting the sensor of kinematic parameter, and the embodiment of the present invention does not limit this.Wherein, it is the acceleration of electronic equipment that acceleration transducer detects the kinematic parameter obtained, and it is the angle of electronic equipment that gyroscope detects the kinematic parameter obtained.
Step 202: the parameter information obtaining target image, this parameter information comprises aperture time and kinematic parameter, the parameter information of based target image, determines the picture quality of target image.
Wherein, because the parameter information of target image not only can comprise aperture time and kinematic parameter, multiple parameters such as aperture, focal length and ISO photosensitivity can also be comprised, therefore, electronic equipment based on different parameter informations, can determine the picture quality of target image.In embodiments of the present invention, the parameter information of electronic equipment based target image, determines that the method for the picture quality of target image can comprise following two kinds, as described below.
The first, when parameter information comprises aperture time and kinematic parameter, the parameter information of electronic equipment based target image, determine that the operation of the picture quality of target image can be: when the aperture time of target image large at fixed time and the kinematic parameter of target image is greater than assign thresholds time, determine that the image parameter of target image is fuzzy.
It should be noted that, fixed time and assign thresholds can be arranged in advance, and such as, this fixed time can be 1/15s, 1/20s etc., and the assign thresholds of acceleration can be 0.5m/s
2, 0.8m/s
2assign thresholds Deng, angle can be 10 degree, 15 degree etc., and embodiment of the present invention contrast does not limit.
The second, when parameter information is except comprising aperture time and kinematic parameter, when also comprising aperture, focal length and ISO photosensitivity, the parameter information of electronic equipment based target image, determine that the operation of the picture quality of target image can be: the aperture time of based target image, kinematic parameter, aperture, focal length and ISO photosensitivity, determine the ambiguity of target image, the ambiguity of target image is the weighted value of the aperture time of target image, kinematic parameter, aperture, focal length and ISO photosensitivity; When the ambiguity of target image is greater than Fuzzy Threshold, determine that the picture quality of target image is fuzzy.
Wherein, when determining the ambiguity of target image, weight ratio corresponding with each parameter for each parameter in aperture time, kinematic parameter, aperture, focal length and ISO photosensitivity can be multiplied, and five product addition that will be multiplied, thus obtain the comprehensive ambiguity of target image.
It should be noted that, the weight ratio that in aperture time, kinematic parameter, aperture, focal length and ISO photosensitivity, each parameter is corresponding arranges in advance, such as, the weight ratio of aperture time is 0.1, the weight ratio of kinematic parameter is 0.3, the weight ratio of aperture, focal length and ISO photosensitivity is 0.2 etc., and the embodiment of the present invention does not do concrete restriction to this.In addition, Fuzzy Threshold also can be arranged in advance, and such as, Fuzzy Threshold is 20,30 etc., and the embodiment of the present invention does not limit this equally.
Further, electronic equipment can respectively by the picture quality of above-mentioned two kinds of method determination target images, above-mentioned two kinds of methods combining can also be used, that is to say, first by aperture time and the kinematic parameter of target image, determine the picture quality of target image, if when the aperture time of target image and kinematic parameter do not meet the condition of above-mentioned first method, the aperture time of based target image, kinematic parameter, aperture, focal length and ISO photosensitivity, determine the ambiguity of target image again.By in conjunction with above-mentioned two kinds of methods, the accuracy determining target image can be improved, simultaneously compared with second method, also improve certain speed, save the time.
Step 203: when obtaining the parameter information of fall short image, electronic equipment can obtain the grey level histogram of target image, the grey level histogram of based target image, determine the average brightness of target image, when the average brightness of target image is greater than the first luminance threshold, determine that the picture quality of target image is over-exposed, when the average brightness of target image is less than the second luminance threshold, determine that the picture quality of target image is for under-exposed.
Because target image can be not only the image of electronic equipment shooting, it can also be the image in photograph album, and the image in photograph album may obtain less than the parameter information such as aperture time or kinematic parameter, therefore, when obtaining the parameter information of fall short image, electronic equipment can determine the quality of target image by step 203.
Wherein, when electronic equipment obtains the grey level histogram of target image, this target image can be thumbnail, because the grey level histogram difference of original image and thumbnail is less, and the definition of thumbnail is lower, therefore, thumbnail can be saved time as target image, 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 greater than the second luminance threshold, such as, first luminance threshold is 180,190, and the second luminance threshold is 90,100 etc., and the embodiment of the present invention is not construed as limiting this.
Step 204: when the picture quality of target image meet any one pre-conditioned time, recommend target image, wherein, pre-conditioned comprise fuzzy, over-exposed and under-exposed.
Through above-mentioned steps 201-203, if to meet in fuzzy, over-exposed or under-exposure arbitrary pre-conditioned for the picture quality of the target image determined, target image is recommended user by electronic equipment, carries out screening and deleting to make user.
Further, electronic equipment according to the final screening of user and can also delete result, the weight ratio corresponding to each parameter in the aperture time related in above-mentioned steps 202, kinematic parameter, aperture, focal length and ISO photosensitivity adjusts, to make the requirement of target image closer to user of recommendation.
Wherein, because aperture time, kinematic parameter, focal length or ISO photosensitivity are larger, target image more easily occurs fuzzy, aperture is less, target image more easily occurs fuzzy, therefore, can adjust based on the weight ratio that such principle is corresponding to each parameter in aperture time, kinematic parameter, aperture, focal length and ISO photosensitivity.
Such as, when the quantity of the target image recommended is more, and the quantity that user finally deletes less time, the weight ratio that aperture time, kinematic parameter, focal length or ISO photosensitivity are corresponding can be reduced, increase the weight ratio that aperture is corresponding, to reduce the quantity of the target image recommended, thus make the requirement of target image closer to user of recommendation.
