Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those skilled in the art's every other implementation obtained without creative efforts Example, shall fall within the protection scope of the present invention.
Fig. 1 is please referred to, Fig. 1 is the flow chart for the processing method of taking pictures that the embodiment of the present invention one provides.
The processing method of taking pictures of this preferred embodiment, comprising:
Step S101 acquires the image of photograph subject, obtains original image when detecting photographing instruction.
For example, terminal takes pictures to photograph subject when user presses camera button, original image is obtained, the original graph As for being used as base map；The terminal can be the equipment such as mobile phone, tablet computer.
Step S102 obtains the number of face in the acquisition time and the original image of the original image.
For example, terminal obtains the acquisition time of the aperture time namely original image currently taken pictures, and use recognition of face Technology identifies the face in original image, and obtains the number of face in the original image；And judge the face number Whether preset quantity is greater than, to determine whether to take pictures for more people.If the face number is less than or equal to preset quantity, sentence Fixed is not that more people take pictures, therefore terminal can not be dealt with, if the face number is greater than preset quantity, judgement is that more people clap According to subsequent to execute step S103.
Step S103 judges whether the acquisition time is less than preset threshold when the number of the face is greater than preset quantity.
For example, whether the aperture time that terminal judgement is currently taken pictures is less than default threshold when terminal is determined as that more people take pictures Value, relatively good with the ambient light that determination is current, which can set based on experience value.If terminal determines current clap According to aperture time be more than or equal to preset threshold, it is determined that current ambient light is poor, then terminal can not be made to locate Reason；If terminal determines that the aperture time currently taken pictures is less than preset threshold, it is determined that current ambient light is relatively good, then holds Row step S104.
Step S104 acquires the image of each face when the acquisition time is less than preset threshold, obtains replacement face Image.
For example, when terminal determines that the aperture time currently taken pictures is less than preset threshold namely current environment light is relatively good When, terminal acquires the image of each face again, obtains replacement facial image.
Step S105 is replaced the image for corresponding to face in the original image using the replacement facial image, obtains photo.
For example, corresponding to the image of face in the image replacement base map of each face of terminal acquisition of taking pictures for the second time, obtain To final photo.
The processing method of taking pictures of this preferred embodiment, due to when detecting photographing instruction, acquiring the image of photograph subject, Obtain original image；Obtain the number of face in the acquisition time and the original image of the original image；As of the face When number is greater than preset quantity, judge whether the acquisition time is less than preset threshold；If the acquisition time is less than the preset threshold, The image for acquiring each face obtains replacement facial image；It is replaced using the replacement facial image corresponding in the original image The image of face, obtains photo；It takes pictures, is reused to defocused facial image replacement due to carrying out focusing to each face again Face in original image, therefore improve clarity.
Referring to figure 2., Fig. 2 is the flow chart of processing method provided by Embodiment 2 of the present invention of taking pictures.
The processing method of taking pictures of this preferred embodiment, comprising:
Step S201 acquires the image of photograph subject, obtains original image when detecting photographing instruction.
For example, terminal takes pictures to photograph subject when user presses camera button, original image is obtained, the original graph As for being used as base map；The terminal can be the equipment such as mobile phone, tablet computer.
Step S202 obtains the number of face in the acquisition time and the original image of the original image.
For example, terminal obtains the acquisition time of the aperture time namely original image currently taken pictures, and use recognition of face Technology identifies the face in original image, and obtains the number of face in the original image；And judge the face number Whether preset quantity is greater than, to determine whether to take pictures for more people.If the face number is less than or equal to preset quantity, sentence Fixed is not that more people take pictures, therefore terminal can not be dealt with, if the face number is greater than preset quantity, judgement is that more people clap According to subsequent to execute step S203.
Step S203 judges whether the acquisition time is less than preset threshold when the number of the face is greater than preset quantity.
For example, whether the aperture time that terminal judgement is currently taken pictures is less than default threshold when terminal is determined as that more people take pictures Value, relatively good with the ambient light that determination is current, which can set based on experience value.If terminal determines current clap According to aperture time be more than or equal to preset threshold, it is determined that current ambient light is poor, then terminal can not be made to locate Reason；If terminal determines that the aperture time currently taken pictures is less than preset threshold, it is determined that current ambient light is relatively good, then holds Row step S204.
Step S204 obtains the area value of each face if the acquisition time is less than the preset threshold；
For example, when terminal determines that the aperture time currently taken pictures is less than preset threshold namely current environment light is relatively good When, terminal obtains the area of each human face region in original image.When relatively good due to ambient light, it just can ensure that acquisition is clear Image can be unintelligible to avoid the facial image obtained again therefore by judging the quality of ambient light, reduce terminal Power consumption.
Step S205 determines whether the face is face to be collected according to the area value of each face；
For example, terminal screens each face according to the area of human face region, to determine the need for the face Image resurveyed, which is such as to need the face taken pictures again.
In order to improve the treatment effeciency of terminal, terminal can compare the area of each human face region and preset area value Compared with the area value for just resurveying image namely each face of the basis to the biggish face of human face region area ratio determines The step of whether face is face to be collected include:
(1) judge whether the area value of the face is greater than preset area value；
(2) if the area value of the face is greater than the preset area value, it is determined that the face is face to be collected.
For example, terminal judges whether the area of each human face region is bigger, which can be based on experience value Setting, the terminal face bigger to area is focused again to obtain its image, due to the lesser face of area ratio, even if Again focusing is taken pictures, and will not improve clarity, therefore terminal no longer focuses to the lesser face of area again and takes pictures, and Focusing is re-started to the biggish face of area to take pictures.
Step S206, however, it is determined that the face is the face to be collected, acquires the image of the face to be collected, obtains replacement people Face image.
For example, terminal carries out focusing to the face again and takes pictures, when the area of human face region is bigger to obtain the people The image of face obtains replacement facial image.
Certainly, in order to improve treatment effeciency and the flexibility of terminal, terminal may determine that when taking pictures total of face to be collected Between, according to the image of face quantity namely the acquisition face to be collected finally to be taken pictures of total time screening, replaced The step of facial image includes
A, the total duration for acquiring the image of all faces to be collected is obtained, the first total duration is obtained；
For example, terminal obtains the number of the face to be collected, and calculated always according to face number to be collected and acquisition time Duration, namely obtain the first total duration.
B, the quantity that the face to be collected is adjusted according to first total duration, obtains target collecting quantity；
For example, terminal judges whether first total duration meets preset condition, if first total duration meets default item Part, then terminal to the quantity of face to be collected without adjustment, if first total duration is unsatisfactory for preset condition, terminal pair The quantity of face to be collected is adjusted.
Certainly, in order to further increase the treatment effeciency of terminal, the quantity namely target that can turn face to be collected down are adopted Collect quantity of the quantity less than face to be collected namely this adjusts the quantity of the face to be collected according to first total duration, obtains The step of target collecting quantity includes:
B1, judge whether first total duration is greater than preset time value；
If b2, first total duration are less than or equal to the preset time value, it is to be collected which is equal to this The quantity of face；
If b3, first total duration are greater than the preset time value, the quantity of the face to be collected is reduced, and trigger acquisition First total duration, until first total duration is less than or equal to the preset time value, by the quantity of the face to be collected after reduction As target collecting quantity.
For example, terminal judges whether the total duration of taking pictures of all faces to be collected is less than preset time value, when this is default Between value can set based on experience value, for example the preset time value is the longest photo opporunity that can bear of user.If this One total duration is no more than the preset time value, then terminal is not adjusted the quantity of face to be collected, i.e., finally acquires face Quantity be equal to face to be collected quantity.If first total duration is more than the preset time value, terminal reduces to be collected The quantity of face, and return to step A namely terminal and reacquire the face of acquisition face quantity after reducing and take pictures always Duration, judges whether the total duration of taking pictures of the face of the quantity of the face to be collected after reducing is less than preset threshold, if it is, Using the acquisition face quantity after reduction as the face quantity namely target collecting quantity finally acquired.If it is not, then continuing Reduce the face quantity, the total duration of taking pictures of the face of the quantity of the face to be collected after reducing, will less than preset threshold Face quantity at this time is as the face quantity finally acquired.
C, the image for acquiring each of the face of target collecting quantity face obtains replacement image.
For example, terminal carries out Image Acquisition to each of the quantity of face to be collected adjusted face, replaced Image.
In order to improve collecting efficiency, terminal can according to the face of target collecting quantity put in order to each face into Row take pictures, the image of each of face of acquisition target collecting quantity face, obtain replacement image the step of include:
L, according to preset order, the image of each of the face of target collecting quantity face is acquired.
For example, terminal is taken pictures according to face of the sequence from front to back or from back to front to target collecting quantity, For the face in same row according to sequence from left to right or from right to left, to each of the face of target collecting quantity Face take pictures.
In order to improve collecting efficiency, terminal can according to the face of target collecting quantity size to each face into Row take pictures, the image of each face in the face of the acquisition second number to be collected, obtain replacement image the step of include:
N, according to the face area value size of the target collecting quantity, to each of the face of the target collecting quantity The image of face is acquired.
For example, the sequence that terminal is descending or ascending according to the area value of the face of target collecting quantity, according to Secondary taking pictures to each of the face of target collecting quantity face.
Step S207 is replaced the image for corresponding to face in the original image using the replacement facial image, obtains photo.
For example, corresponding to the image of face in the image replacement base map of each face of terminal acquisition of taking pictures for the second time, obtain To final photo.
The processing method of taking pictures of this preferred embodiment, on the basis of first embodiment, due to the area pair according to face Face in all photograph subjects is screened, and the face for being only greater than preset value to face area is taken pictures again, therefore is mentioned High treatment effeciency.
Referring to figure 3., Fig. 3 is the flow chart for the processing method of taking pictures that the embodiment of the present invention three provides.
The present embodiment is described in detail taking the terminal as an example, the processing method of taking pictures of this preferred embodiment, comprising:
Step S301, when detecting photographing instruction, mobile phone acquires the image of photograph subject, obtains original image.
For example, mobile phone takes pictures to photograph subject when user presses camera button, original image is obtained, the original graph As for being used as base map.
Step S302, mobile phone obtain the number of face in the acquisition time and the original image of the original image.
For example, mobile phone obtains the generation time of the aperture time t0 namely original image that currently take pictures, and known using face Other technology identifies the face in original image, and obtains the number of face in the original image；And judge the face Whether number is greater than 2, to determine whether to take pictures for more people, if the face number is less than or equal to 2, determines it is not that more people clap According to, therefore mobile phone can not be dealt with, if the face number is greater than 2, judgement is that more people take pictures, and then executes step S303。
Step S303, when the number of the face is greater than preset quantity, it is default that mobile phone judges whether the acquisition time is less than Threshold value.
For example, when mobile phone is determined as that more people take pictures, the aperture time that mobile phone judgement is currently taken pictures whether less than 2 minutes, Relatively good with the ambient light that determination is current, which can set based on experience value.If mobile phone judgement is currently taken pictures Aperture time be more than or equal to 2 minutes, it is determined that current ambient light is poor, then mobile phone can not be dealt with；Such as Fruit mobile phone determines the aperture time currently taken pictures less than 2 minutes, it is determined that current ambient light is relatively good, thens follow the steps S304。
Step S304, if the acquisition time is less than the preset threshold, mobile phone obtains the area value of each face.
For example, when mobile phone determines the aperture time currently taken pictures less than 2 minutes namely when relatively good current environment light, Then mobile phone obtains the area of each human face region in original image.When relatively good due to ambient light, it just can ensure that acquisition is clear Image can be unintelligible to avoid the facial image obtained again therefore by judging the quality of ambient light, reduce mobile phone Power consumption.
Step S305, mobile phone screen all faces according to the area value of the face, and obtain the face after screening Take pictures total time.
For example, mobile phone judges whether the area value of the face is greater than preset threshold；It is preset when the area value of the face is greater than When threshold value, mobile phone takes pictures again to the face, and obtains when the taking pictures total of face that all area values are greater than preset threshold Between t1.And when area value is less than or equal to the face of preset threshold, mobile phone does not take pictures again to the face.
Step S306, mobile phone judge whether the total time of taking pictures is less than preset time value, obtain judging result.
For example, mobile phone judges whether t1 is less than preset time value T, for example mobile phone obtains all area values and is greater than preset threshold The total quantity of face be the sum of face after n, namely screening be n, t1 is specifically as follows shown in formula 1:
T1=n*t0 formula 1
Step S307, mobile phone generate face acquisition queue according to the judgment result；
For example, n face is acquired queue by mobile phone when mobile phone determines that t1 is less than T；If mobile phone t1 is greater than Or being equal to T, then mobile phone reduces the quantity n of the face after screening, and the total time of taking pictures of the face after reducing is small In preset time value, queue is acquired using n face after reduction as face.
Specifically, n is subtracted 1, then calculates the total time t2 that n-1 face is taken pictures, judge whether t2 is less than T, if t2 is less than T, then face acquisition queue is n-1 face, otherwise subtracts 1 again for n-1, obtains the total time t3 that takes pictures of n-2 face again, and Judge whether t3 is less than T, if so, face acquisition queue is otherwise n-2 face continues to subtract 1 for n-2, after reducing The total time of taking pictures of face is less than preset time value T.Such as n-x, the total time of always taking pictures of face is less than preset time value T, then face acquisition queue is n-x face.Wherein n-x is greater than 0, and x is greater than 0 and is less than n, and n is natural number.
Step S308, mobile phone carry out Image Acquisition to each face of face acquisition queue, obtain replacement image；
For example, having 6 faces in face acquisition queue, then mobile phone focus to each of 6 faces face and take pictures, Obtain the replacement image of each face.Such as there are 4 faces in front in this 6 faces, behind there are two face.Specifically, hand Machine can first take pictures according to 4 faces of the sequence from left to right to front, according still further to sequence from left to right to below 2 faces take pictures.Or mobile phone carries out Image Acquisition to this 6 faces respectively according to the size of this 6 faces, For example the sequence successively decreased according to area value takes pictures to this 6 faces.
Step S309, mobile phone are replaced the image for corresponding to face in the original image using the replacement facial image, are shone Piece.
For example, corresponding to the image of face in the image replacement base map of 6 faces of mobile phone acquisition of taking pictures for the second time, obtain Final photo.
The processing method of taking pictures of this preferred embodiment, due to mobile phone according to the area of face to the people in all photograph subjects Face is screened, later further according to the screening of duration again to face progress of taking pictures of all photos after screening, to second Face after screening is taken pictures, and replacement facial image is obtained, and replaced using the replacement facial image it is right in the original image The image of face is answered, therefore improves flexibility.
