Fig. 1 is the flow chart that a kind of acquisition parameters according to an exemplary embodiment determine method, the acquisition parameters
The method of determination be can apply in terminal, and camera and positioning component are provided with the terminal.This method can include following step
Suddenly.
Step 101, the first camera site and the first acquisition parameters of terminal are recorded.
Wherein, the first acquisition parameters are the parameters when the first camera site is shot, for representing that terminal is receiving
To the parameter value of taking pictures that during shooting instruction, terminal is set automatically according to environmental light parameter.Alternatively, environmental light parameter includes：Ring
Border luminous intensity, and/or, environment light color temperature.
When user clicks on shutter, terminal receives the first shooting instruction.Terminal determines to receive the first shooting instruction
When, the locus of terminal is determined by positioning component, and the locus is stored as the first camera site.
Meanwhile terminal also obtains the parameter value of taking pictures when receiving the first shooting instruction, the parameter value of taking pictures is regard as the
One acquisition parameters are stored in terminal.
Step 102, when receiving shooting instruction, determine movement between the second camera site and the first camera site away from

After terminal moves from the first camera site, when user again taps on shutter, terminal receives the second shooting again
Instruction.Terminal obtains locus when receiving the second shooting instruction, using the locus as the second camera site, and counts
Calculate the displacement between the second camera site and the first camera site.
Wherein, displacement can be by pre-establishing rectangular coordinate system in space, and computing terminal is in rectangular coordinate system in space
Three directions on the distance that moves respectively, and the distance by being moved respectively on three directions calculated from the first camera site
It is moved to the actual displacement of the second camera site；Or pass through GPS (Global Positioning System, the whole world
Alignment system) the first camera site and the second camera site are positioned, then calculate between the first camera site and the second camera site
Displacement；Or wireless signal is sent to terminal by three Wi-Fi anchor points of indoor setting, received according to terminal
The attenuation degree for the wireless signal that the Wi-Fi anchor points arrived are sent, determines the first camera site and the second camera site, then calculate
Displacement between first camera site and the second camera site.The embodiment of the present disclosure is not added with to the calculation of displacement
To limit.
Step 103, when displacement is less than default mobile threshold value, determine that the second shooting is joined according to the first acquisition parameters
Number, the difference between the first acquisition parameters and the second acquisition parameters are less than predetermined threshold value.
A mobile threshold value is preset in terminal, when terminal is moved to from the first camera site the shifting of the second camera site
When dynamic distance is more than the movement threshold value, it is determined that this time mobile situation larger for displacement, terminal is voluntarily according to environment beche-de-mer without spike
Number calculates the second acquisition parameters of the second camera site, and is shot according to the second acquisition parameters.Alternatively, environment beche-de-mer without spike
Number includes：Ambient light intensity and/or environment light color temperature.
When terminal from the first camera site be moved to second count act as regent the displacement that postpones be less than the movement threshold value when, really
Fixed this time movement is the less situation of displacement, and terminal determines the second acquisition parameters according to the first acquisition parameters, and guarantee the
Difference between one acquisition parameters and the second acquisition parameters is less than preset difference value.Namely ensure the first acquisition parameters and the second shooting
It will not be mutated between parameter.
Alternatively, terminal determines that the second acquisition parameters can include according to the first acquisition parameters：First acquisition parameters are straight
Connect and be multiplexed with the second acquisition parameters, or, as second after the first acquisition parameters and prediction acquisition parameters are weighted averagely
Acquisition parameters, prediction acquisition parameters are the acquisition parameters that terminal is voluntarily determined according to environmental light parameter.
In addition, predetermined threshold value is used to judge the difference between the acquisition parameters of terminal first and the second acquisition parameters, when first
When difference between acquisition parameters and the second acquisition parameters is more than predetermined threshold value, represent that the Parameters variation of taking pictures of terminal is larger, clap
It is larger to take the photograph effect difference；When the difference between the first acquisition parameters and the second acquisition parameters is less than predetermined threshold value, terminal is represented
Parameters variation of taking pictures it is smaller, shooting effect difference it is smaller.Terminal only needs to ensure the first acquisition parameters and the second acquisition parameters
Between difference be less than predetermined threshold value, when actually realizing, terminal be not necessarily to the differences of two groups of acquisition parameters with it is pre-
If threshold value is compared, the predetermined threshold value also not necessarily clearly stores in the terminal.
Step 104, shot according to the second acquisition parameters.
After terminal gets the second acquisition parameters, terminal is configured according to the second acquisition parameters to acquisition parameters, and
Shot according to acquisition parameters.
In summary, the acquisition parameters provided in the embodiment of the present disclosure determine method, by judge the first camera site with
The magnitude relationship between displacement and default mobile threshold value between second camera site, when displacement is less than default movement
During threshold value, the second acquisition parameters are determined according to the first acquisition parameters, terminal is shot according to the second acquisition parameters, so as to solve
When terminal, when different distance shoots same object, acquisition parameters numerical value difference is larger, causes the photograph taking effect shot
The problem of differing greatly, reach when the moving range of terminal is smaller, the acquisition parameters of terminal carry without the effect of mutation
High user carries out the shooting quality for the photo that photographing operation obtains.
Fig. 2 is a kind of flow chart of parameter determination method of taking pictures according to another exemplary embodiment, the ginseng of taking pictures
Number determination method is applied in terminal, and camera and positioning component are provided with the terminal.Alternatively, the positioning component is to accelerate
Spend sensor and/or GPS.This method comprises the following steps：
Step 201, the first camera site and the first acquisition parameters of terminal are recorded.
Wherein, the first acquisition parameters are the parameters when the first camera site is shot, and can be used to indicate that terminal exists
When receiving the first shooting instruction, parameter value of taking pictures that terminal is set automatically according to environmental light parameter.
When user clicks on shutter, terminal receives the first shooting instruction.Terminal determines to receive the first shooting instruction
When terminal locus, and the locus is stored as the first camera site.
Meanwhile terminal also obtains the parameter value of taking pictures when receiving the first shooting instruction, the parameter value of taking pictures is regard as the
One acquisition parameters are stored in terminal.
Wherein, the first acquisition parameters can include but is not limited to：F-number, fast gate value, color temperature value, light exposure, white balance
At least one of value.
Such as first acquisition parameters be：F-number is F2, fast gate value is 1/150s, color temperature value 2700k, light exposure are
4。
It should be noted that after camera application program is opened, acquisition parameters when terminal can shoot first time are made
For the first acquisition parameters, acquisition parameters when terminal can also shoot ith are as the first acquisition parameters, and the present embodiment is to this
It is not limited.In other words, the first time in " first " not necessarily actual photographed in the present embodiment, but refer to
The repeatedly ith in shooting；Second in " second " not necessarily actual photographed in the present embodiment, but refer to repeatedly
I+1 time in shooting.
Step 202, acceleration of the terminal in three reference axis of default rectangular coordinate system in space is recorded.
Acceleration transducer is provided with terminal, acceleration transducer can collect mobile acceleration of the terminal in movement
Degree.
Rectangular coordinate system in space is established as origin using any point in terminal.When terminal moves from the first camera site
During the second camera site, terminal obtains three reference axis of rectangular coordinate system in space by acceleration transducer respectively
Acceleration on direction.
Such as using the position where acceleration transducer as origin, using perpendicular to the direction of terminal as Z-direction,
Using the short side of terminal as X-axis, rectangular coordinate system in space is established as Y-axis using the long side of terminal.
Step 203, the acceleration in three reference axis is integrated, obtains the displacement in three reference axis.
Terminal obtains carries out the first shooting time of photographing operation in the first camera site, obtains and enters in the second camera site
Second shooting time of row photographing operation, and the time difference between the first shooting time and the second shooting time is obtained, when comparing
Between it is poor with the magnitude relationship of default time threshold.
When the time difference being more than time threshold, because the adjacent interval that shoots twice is too long, terminal can not consider first
The influence of acquisition parameters, terminal automatically determine out the second acquisition parameters according to second count according to the environmental light parameter at moment.
When the time difference being less than time threshold because it is adjacent shoot twice it is closely spaced, terminal need consider first count
Take the photograph the influence of parameter, terminal obtains the acceleration on three change in coordinate axis direction of rectangular coordinate system in space, and when being shot with first
The period between the second shooting time is carved as the time of integration, the acceleration on three change in coordinate axis direction is accumulated respectively
Point, calculate the distance that terminal moves on three change in coordinate axis direction.
For example terminal is 0s in the first shooting time that the first camera site carries out shooting operation, in the second camera site
The second shooting time for carrying out shooting operation is 1s, and terminal calculates terminal and is moved to the second camera site from the first camera site
Time difference be 1s, it is assumed that default time threshold be 1 minute, therefore the time difference be less than time threshold.Acted as regent from first count
Put during being moved to the second camera site, the acceleration that terminal is got in the X-direction of rectangular coordinate system in space is
2cm/s2, the acceleration in Y direction is 4cm/s2, the acceleration in Z-direction is 8cm/s2.Terminal is respectively to three coordinates
Acceleration on direction of principal axis carries out quadratic integral, and obtaining terminal, displacement is 1cm in the X-axis direction, and terminal is in the Y-axis direction
Mobile distance is 2cm, and the distance that terminal moves in the Z-axis direction is 4cm.
Step 204, according to the displacement in three reference axis, calculate between the second camera site and the first camera site
Displacement.
Terminal gets terminal after three distances just moved up of reference axis according to formula
The displacement of computing terminal.
Wherein, D is the distance between the second camera site and the first camera site, x0Moved for terminal from the first camera site
Move second count to act as regent the distance for postponing and moving in the X-axis direction, y0For terminal the second shooting is moved to from the first camera site
The distance moved in the Y-axis direction behind position, z0From the first camera site second count is moved to for terminal acts as regent postpone in Z axis side
The distance moved up.
For example the distance that terminal moves in the X-axis direction is x0=1cm, the distance that terminal moves in Y-axis are y0=
2cm, the distance that terminal moves on Z axis are z0=4cm, therefore, terminal are moved to the second picture-taking position from the first picture-taking position
Displacement
Alternatively, because the position error of acceleration transducer is small but drift error is very big, GPS position error is big but floats
Shift error very little, so the present embodiment also includes following calibration process：
Step 205, when receiving shooting instruction, the second calibration camera site is obtained by GPS.
When terminal is receiving the second shooting instruction on the second camera site, terminal also passes through global position system GPS
Obtain the second calibration camera site that terminal is currently located.
Step 206, the second calibration the distance between camera site and the first camera site is calculated, as reference distance.
For example terminal is calculated the distance between second calibration camera site and the first camera site by GPS and is
8cm, therefore 8cm is reference distance.
Step 207, displacement is calibrated using reference distance.
Because terminal is larger using drift error caused by the displacement of integral and calculating terminal, and determined using GPS
The drift error of position and the displacement of the terminal by being calculated is smaller, and therefore, terminal is using GPS location mode to terminal
Displacement calibrated.
When displacement and reference distance difference, terminal is calibrated using reference distance to displacement.
Step 208, when displacement is less than default mobile threshold value, the first acquisition parameters are multiplexed with the second shooting ginseng
Number.
When displacement is less than default mobile threshold value, the first acquisition parameters are directly multiplexed with the second shooting and joined by terminal
Number.
Step 211, shot according to the second acquisition parameters.
After terminal gets the second acquisition parameters, shot according to the second acquisition parameters.
It should be noted that step 202-204 and step 205-206 does not have sequencing only to perform step 202-
204, or, step 202-204 and step 205-206 carries out simultaneously.
In an optional embodiment, step 208 can also replace with step 209 to step 210.
Step 209, when displacement is less than default mobile threshold value, use environment optical parameter automatically determines out prediction shooting
Parameter.
Wherein, the method that terminal use environment optical parameter automatically determines out prediction acquisition parameters, can include：Work as end
When under exposal model, terminal obtains the environmental light parameter of surrounding with sometime interval automatically, and by environmental light parameter certainly
It is dynamic to determine to predict acquisition parameters.
Or, taken pictures when terminal is under state, when terminal gets photographing instruction, it is automatic that terminal obtains environmental light parameter
Determine to predict acquisition parameters.
Step 210, it is weighted averagely using the first acquisition parameters and prediction acquisition parameters, obtains the second acquisition parameters.
When the displacement of terminal is less than default mobile threshold value, the first acquisition parameters and prediction acquisition parameters are added
Weight average obtains the second acquisition parameters.
Alternatively, because the first acquisition parameters include many kinds of parameters, prediction acquisition parameters also include many kinds of parameters.Carry out
During weighted average, the acquisition parameters that same type is belonged in the first acquisition parameters and prediction acquisition parameters are weighted average.
For example the color temperature value of the color temperature value in the first acquisition parameters and prediction acquisition parameters is weighted average, the first acquisition parameters
In light exposure and prediction acquisition parameters light exposure be weighted it is average, and be unable to different type parameter be weighted it is average.
Alternatively, whole parameters in the first acquisition parameters and prediction acquisition parameters are weighted average or only right
Partial parameters are weighted average.
Wherein, the weighted value of the first acquisition parameters and the weighted value of default acquisition parameters can be fixed weighted value,
Can actual photographed situation is dynamically determined according to weighted value.But the weighted value of the first acquisition parameters and default acquisition parameters
Weighted value and equal to 1.
In summary, the acquisition parameters provided in the embodiment of the present disclosure determine method, by judge the first camera site with
The magnitude relationship between displacement and default mobile threshold value between second camera site, when displacement is less than default movement
During threshold value, the second acquisition parameters are determined according to the first acquisition parameters, terminal is shot according to the second acquisition parameters, so as to solve
When terminal, when different distance shoots same object, acquisition parameters difference is larger, causes the photograph taking difference on effect shot
The problem of larger, reach when the moving range of terminal is smaller, the acquisition parameters of terminal are improved and used without the effect of mutation
Family carries out the shooting quality for the photo that photographing operation obtains.
The acquisition parameters provided in the embodiment of the present disclosure determine method, by obtaining terminal in rectangular coordinate system in space
Acceleration, computing terminal moves up distance in three sides of reference axis, and computing terminal is moved to from the first camera site
The displacement of two camera sites, the effect accurately calculated displacement of the terminal in short-distance movement is reached.
The acquisition parameters provided in the embodiment of the present disclosure determine method, and the second calibration shooting position of terminal is obtained by GPS
Put, reference distance is used as by the distance between the calibrating position of terminal second and the first camera site, and with reference distance to moving
Dynamic distance is calibrated, and has reached the effect calibrated to distance of the terminal in short-distance movement, is improved terminal and is calculated
Displacement accuracy.
The acquisition parameters provided in the embodiment of the present disclosure determine method, by being less than predetermined threshold value by first when displacement
Acquisition parameters are assigned to the second acquisition parameters.Reach the acquisition parameters of quick obtaining second and reduce the meter that terminal calculates acquisition parameters
The effect of calculation amount.
The acquisition parameters provided in the embodiment of the present disclosure determine method, by judging the first acquisition parameters and prediction shooting ginseng
Number, which is weighted, averagely obtains the second acquisition parameters, has reached the effect for obtaining the preferable acquisition parameters of shooting effect.

Between it is poor with the magnitude relationship of default time threshold.
When the time difference being more than time threshold, because the adjacent interval that shoots twice is too long, terminal can not consider first
The influence of acquisition parameters, terminal automatically determine out the second acquisition parameters according to second count according to the environmental light parameter at moment.
When the time difference being less than time threshold because it is adjacent shoot twice it is closely spaced, terminal need consider first count
Take the photograph the influence of parameter, terminal obtains the acceleration on three change in coordinate axis direction of rectangular coordinate system in space, and when being shot with first
The period between the second shooting time is carved as the time of integration, the acceleration on three change in coordinate axis direction is accumulated respectively
Point, calculate the distance that terminal moves on three change in coordinate axis direction.
For example terminal is 0s in the first shooting time that the first camera site carries out shooting operation, in the second camera site
The second shooting time for carrying out shooting operation is 1s, and terminal calculates terminal and is moved to the second camera site from the first camera site
Time difference be 1s, it is assumed that default time threshold be 1 minute, therefore the time difference be less than time threshold.Acted as regent from first count
Put during being moved to the second camera site, the acceleration that terminal is got in the X-direction of rectangular coordinate system in space is
2cm/s2, the acceleration in Y direction is 4cm/s2, the acceleration in Z-direction is 8cm/s2.Terminal is respectively to three coordinates
Acceleration on direction of principal axis carries out quadratic integral, and obtaining terminal, displacement is 1cm in the X-axis direction, and terminal is in the Y-axis direction
Mobile distance is 2cm, and the distance that terminal moves in the Z-axis direction is 4cm.
In step 304, according to the displacement in three reference axis, calculate the second camera site and the first camera site it
Between displacement.
Terminal gets terminal after three distances just moved up of reference axis according to formula
The displacement of computing terminal.
Wherein, D is the distance between the second camera site and the first camera site, x0Moved for terminal from the first camera site
Move second count to act as regent the distance for postponing and moving in the X-axis direction, y0For terminal the second shooting is moved to from the first camera site
The distance moved in the Y-axis direction behind position, z0From the first camera site second count is moved to for terminal acts as regent postpone in Z axis side
The distance moved up.
For example the distance that terminal moves in the X-axis direction is x0=1cm, the distance that terminal moves in Y-axis are y0=
2cm, the distance that terminal moves on Z axis are z0=4cm, therefore, terminal are moved to the second picture-taking position from the first picture-taking position
Displacement
Alternatively, because the position error of acceleration transducer is small but drift error is very big, GPS position error is big but floats
Shift error very little, so the present embodiment also includes following calibration process：
In step 305, when receiving shooting instruction, the second calibration camera site is obtained by GPS.
When terminal is receiving the second shooting instruction on the second camera site, terminal also passes through global position system GPS
Obtain the second calibration camera site that terminal is currently located.
In step 306, the second calibration the distance between camera site and the first camera site is calculated, as reference distance.
For example terminal is calculated the distance between second calibration camera site and the first camera site by GPS and is
8cm, therefore 8cm is reference distance.
Step 307, using reference distance as the displacement after calibration.
When displacement and reference distance difference, terminal can be calibrated using reference distance to displacement.Can
Selection of land, terminal by second calibration camera site and the first camera site between reference distance, directly as the movement after calibration
Distance.
In an optional embodiment, step 307 could alternatively be step 308.
In step 308, average, the displacement after being calibrated is weighted using reference distance and displacement.
When the displacement that terminal is calculated is with reference distance difference, terminal is entered using reference distance and displacement
Row weighted average, using obtained displacement as the displacement after calibration.
Wherein, the weighted value of the weighted value of reference distance and displacement can be fixed value, also can arbitrarily set, but join
Examine the weighted value of distance and the weighted value of displacement and for 1.
Such as, it is assumed that the weighted value of reference position is set in terminal as 0.6, the weighted value of displacement is 0.4, therefore school
Displacement after standard is：0.6 × reference distance+0.4 × displacement.
Step 309, when displacement is less than default mobile threshold value, the first acquisition parameters are multiplexed with the second shooting ginseng
Number.
In an optional embodiment, when the value of displacement is less than predetermined threshold value, terminal is by the first acquisition parameters
Directly it is multiplexed with the second acquisition parameters.
In another optional embodiment, step 309 could alternatively be step 310 to step 313.
Step 310, use environment optical parameter is determined to predict acquisition parameters.
Wherein, the method that terminal use environment optical parameter automatically determines out prediction acquisition parameters, can include：Work as end
When under exposal model, terminal obtains the environmental light parameter of surrounding with sometime interval automatically, and by environmental light parameter certainly
It is dynamic to determine to predict acquisition parameters.
Or, taken pictures when terminal is under state, when terminal gets photographing instruction, it is automatic that terminal obtains environmental light parameter
Determine to predict acquisition parameters.
Step 311, the image quality fraction of the image photographed according to the first acquisition parameters is calculated.
Terminal carries out image quality marking according to the image parameter of the photo shot in the first camera site to the photo.
Wherein, the image quality of image can be by the pixel resolution of photo, color rendition degree, the white balance degree of accuracy, the exposure degree of accuracy
Assessed etc. factor.The present embodiment is not limited to terminal carries out image quality marking using which kind of algorithm.
Step 312, the weights according to corresponding to image quality fraction determines the first acquisition parameters.
The corresponding relation being stored with terminal between image quality marking and weights.Alternatively, image quality marking and power
It is worth correlation.Terminal is after image quality fraction is calculated, and by inquiring about the corresponding relation, determines and the first shooting
Weights corresponding to parameter.
When the image quality fraction of the first acquisition parameters is higher, the weighted value of the first acquisition parameters is arranged to higher value such as
0.7th, 0.8 etc.；When the image quality fraction of the first acquisition parameters is relatively low, the weighted value of the first acquisition parameters is arranged to smaller value
Such as 0.3,0.2.
Image quality fraction is higher, and the weighted value of the first acquisition parameters is bigger；Image quality fraction is lower, the first shooting ginseng
Several weighted values is smaller.
Step 313, the weights according to corresponding to the first acquisition parameters, the first acquisition parameters and prediction acquisition parameters are added
Weight average, obtain the second acquisition parameters.
Such as more a height of 60 points of the default image quality fraction of terminal, then terminal determine the weighted value of the first acquisition parameters
For 0.6, therefore it is 0.4 to predict that the weighted value of acquisition parameters should be 1 to subtract 0.6；Assuming that the imaging matter of the acquisition parameters of terminal-pair first
Amount marking is 70, therefore the weighted value of the first acquisition parameters is 0.7, and the weighted value for predicting acquisition parameters is that 1 to subtract 0.7 be 0.3.
Step 314, shot according to the second acquisition parameters.
After terminal gets the second acquisition parameters, shot according to the second acquisition parameters.
It should be noted that step 302 to step 304 and step 305 to the no sequencing of step 306 can be performed only
Step 302 to step 304 or step 302 is carried out simultaneously to step 304 with step 305 to step 306.
In summary, the acquisition parameters provided in the embodiment of the present disclosure determine method, also by clapping the first camera site
The image taken the photograph carries out image quality marking, and the acquisition parameters higher to image quality fraction set higher weights, to imaging
The relatively low acquisition parameters of mass fraction set relatively low weights, reach and get preferable second acquisition parameters, and then shoot
The effect of the image of better quality.
