The portable digital equipment includes but is not limited to mobile phone, tablet computer, and no fuselage lens module is formed with mobile phoneSystem,
To keep the technical principle, feature and technical effect of technical scheme clearer, below in conjunction with specific realityExample is applied technical scheme is described in detail.
The process of screening photo provided by the embodiments of the present application is as shown in Fig. 2, include the following steps:
Step 201: according to the setting of user, enabling serial-gram screening function.
For example, user clicks the set interface for software of taking pictures, " serial-gram screening " this option is chosen, thus the company of enablingContinuous photo screening function.The step is optional step.
Step 202: user, which opens, to take pictures software and carries out photographing operation, each photo of storage user's shooting.
If portable digital equipment use single task operating system, opening take pictures software be meant that bring into operation take pictures it is softPart；If portable digital equipment uses multiple task operating system, opening takes pictures software in addition to the software of taking pictures that brings into operation, it is also possible toThe software of taking pictures of running background is called in into front stage operation.
Step 203: user exit the operation for software of taking pictures, and software of taking pictures at this time judges that user takes pictures software in openingWhether carry out continuously taking pictures into the process (hereinafter referred to as this shooting process) for exiting software of taking pictures, if executing step204, otherwise, terminate this process.
If portable digital equipment use single task operating system, exit software of taking pictures be meant that end operation take pictures it is softPart；If portable digital equipment uses multiple task operating system, software of taking pictures is exited in addition to terminating to run software of taking pictures, it is also possible toThe software of taking pictures of front stage operation is called in into running background.
Having judged whether to continuously take pictures can be illustrated individually below there are many judgment mode:
Mode one: judged by shooting time.The relevant information that photo would generally be saved when saving photo, includingPhoto opporunity, that is, system time when taking pictures.By comparing when the taking pictures of each photo saved in this shooting processBetween, if there is the interval of the photo opporunity of two photos to be less than preset first threshold, then it is assumed that be the photo continuously taken pictures；The photo continuously taken pictures if it exists determines to have carried out continuously taking pictures in this shooting process.
If there is three or more photos, adjacent two photo opporunities are respectively less than first threshold, then by these photosAs one group of photo of continuously taking pictures.There may be the photo of continuously taking pictures of two or more groups in a shooting process.
Since the response time that different portable digital equipments is taken pictures is different, the habit that everyone takes pictures is also different,The mean value at the interval when first threshold can be user's setting value, system default value or continuously take pictures for the first time, e.g., theFor user altogether by 5 shutters, interval is respectively 5 seconds, 5 seconds, 1 second, 1 second when one-time continuous is taken pictures, and the mean value at interval is calculatedIt is 3 seconds, then sets first threshold to 3 seconds.For nearest use habit of being more close to the users, which is also possible toThe sliding average of the continuous photo opporunity interval mean value of nearest n times.
It, can be to carry out dynamic tune to first threshold according to whether having carried out photo and having deleted according to another embodiment of the applicationSection.For example, deleting photo in photo screening process, it was demonstrated that current judgement is continuously taken pictures effectively, and first threshold is constant, if nothingIt deletes, first threshold (such as reducing by 1 second) is reduced if first threshold is not up to minimum value, is not adjusted if having reached minimum valueIt is whole.Minimum value is the minimum value for the time interval mean value that first time continuously takes pictures or n times are continuously taken pictures recently (for example, for the first timeUser is altogether by 5 shutters when continuously taking pictures, and interval is respectively 5 seconds, 5 seconds, 1 second, 1 second, then minimum value is 1 second；Alternatively, recentlyThe time interval mean value continuously taken pictures three times is respectively 2 seconds, 2.5 seconds, 3 seconds, then minimum value is 2 seconds).
Mode two: judged by shooting time combination shooting location.
Only by time interval to determine whether continuously take pictures, but if portable digital equipment is in mode oneIn movement, even if then shooting interval is very short twice, photo picture may also be very different, therefore also need to combine shooting groundPoint is judged.
When taking pictures, changing coordinates are obtained by location-based service, and coordinate information is stored in photo relevant information.It is rightIt is less than the photo of first threshold in time interval, further calculates the distance between its coordinate, if distance is less than second threshold,Then it is considered the photo continuously taken pictures, is otherwise not considered as the photo continuously taken pictures.
In some cases, user may stand and take pictures in same place to different directions in a relatively short period of time.If clappedIrradiation angle difference is larger, and the photo content obtained in this way has very big difference, is not belonging to the photo that should be screened, it is therefore desirable to willSuch case excludes.
When taking pictures, believed by the optical axis direction of gravity sensor and GPS acquisition camera built in portable digital equipmentBreath, and by direction information preservation in photo relevant information.For being judged as in one group of photo of continuously taking pictures, it is calculatedThe differential seat angle of the Space Angle of optical axis direction, if there is the differential seat angle of two or two or more photos is greater than third threshold value, then by thisA little photos are further divided into smaller group, wherein the differential seat angle of the optical axis direction of any two photos in each group is respectively less thanThird threshold value.
In the embodiment of the present application, the value range of the third threshold value is 5 degree to 30 degree.
Mode three is judged by photo picture content.
The picture similarity of the photo obtained in this operational process of software of taking pictures can be calculated by image recognition algorithm,The photo continuously taken pictures is considered if similarity is more than the 4th threshold value；The photo continuously taken pictures if it exists determines this batContinuously take pictures during taking the photograph；If there is three or more photos, adjacent two similarities are respectively less than the 4th threshold value,Then using these photos as one group of photo of continuously taking pictures.The similarity can be whole pictures based on photo, be also possible toBased on part of content, for example, picture beginning and end 10% content.The value range of 4th threshold value can be50% to 90%.
Mode three can also be combined with mode one to two.To avoid erroneous judgement.
Step 204: the photo continuously taken pictures being screened, the wherein preferable photo of quality is retained.
The screening can be divided into manual screening mode and automatic screening mode.Taking pictures software can setting according to userIt sets, one of mode is selected to be operated.
Under manual screening mode, the photo continuously taken pictures is shown in a manner of several on the screen, user passes through touch screenCurtain chooses the photo for needing to retain (or deletion), then presses " determination " button shown on screen, then according to the user's choice,Delete corresponding photo.Preferably, one group of photo of continuously taking pictures can once be shown, the photo of continuously taking pictures of difference group is divided into moreSecondary display, to facilitate user to select.
Under automatic screening mode, for one group of photo of continuously taking pictures, the clarity of photo picture is calculated first, it will be clearPoor photo is spent to delete；Then, the similarity that photograph image is calculated according to image recognition algorithm, from the higher photo of similarityThe middle selection 1-3 highest photos of quality, remaining photo is deleted.
