In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper
Technical solution is stated to be described in detail.
Embodiment one
The embodiment of the present application one provides a kind of method of Image Acquisition, and the method, which is applied, to be included or be connected with projection dress
It puts in the electronic equipment with image collecting device, the electronic equipment is, for example,：Laptop, mobile phone, tablet computer etc..
It please refers to Fig.1, the method for described image acquisition includes the following steps：
Step S101：At the t1 moment, when carrying out Image Acquisition to first area based on described image harvester, pass through
The projection arrangement uses the mode of projection to carry out light filling to the first area with the first projection frequency parameter；
Step S102：At the t2 moment, by described image harvester with relevant with the described first projection frequency parameter
The first image described in first frequency acquisition parameter acquisition corresponding to first area, so that described in the acquisition of described image harvester
During i-th of subgraph of the first image, j-th of subgraph of described first image carries out light filling by the projection arrangement,
In, at the time of the t1 moment and the t2 moment are identical or the t2 moment be at the time of after the t1 moment,
I, j is more than or equal to i for the arbitrary integer more than 1 and j.
In specific implementation process, various ways may be employed, the projection arrangement and described image harvester are carried out
Control, with ensure described image harvester acquisition described first image i-th of subgraph when, the jth of described first image
A subgraph carries out light filling by the projection arrangement, wherein, a subgraph of described first image is, for example,：Described first
A pixel in image is set forth below two kinds therein and is introduced, certainly, in specific implementation process, be not limited to
Lower two kinds of situations.
The first, please refers to Fig.2, in based on step S101, with the in a manner that the projection arrangement uses projection
Before one projection frequency parameter carries out light filling to the first area, the method further includes following steps：
Step S201：Determine the second frequency acquisition corresponding to the t3 moment of described image harvester before time tl
Parameter；
Step S202：Based on the second frequency acquisition parameter, by described image harvester the t1 moment acquisition frequency
Rate is determined as the first frequency acquisition parameter.
Wherein, in step S201, the camera sense of the depth of exposure of first area and image collecting device under normal conditions
Luminosity can correspond to the second frequency acquisition parameter of an image collecting device, wherein, the depth of exposure of first area is higher or schemes
As the camera sensitivity value of harvester is higher, the second image institute corresponding to first area described in image acquisition device
Corresponding rate is faster, and then makes the second frequency acquisition parameter higher.
Wherein, in step S202, based on the second frequency acquisition parameter by described image harvester at the t1 moment
Frequency acquisition is determined as the first frequency acquisition parameter and can be set forth below two kinds therein there are many situation and be situated between again
It continues.
（1）It please refers to Fig.3, specifically comprises the following steps：
Step S301：Judge it is described first projection frequency parameter whether be the second frequency acquisition parameter integral multiple；
Step S302a：When the described first projection frequency parameter is the integral multiple of the second frequency acquisition parameter, determine
The frequency acquisition is the first frequency acquisition parameter identical with the second frequency acquisition parameter.
Wherein, in step S301, the first projection frequency parameter for 60Hz and is under normal conditions projection arrangement
One scan period is 1/60s, certainly, the first projection frequency parameter or other values, such as：50Hz, 70Hz etc.
Deng the embodiment of the present application is not restricted.
Wherein, based on the second frequency acquisition parameter determined in step S201, it is possible to determine second acquisition
Whether frequency parameter is the described first whole approximate number for projecting frequency parameter, such as：If the second frequency acquisition parameter is：
12Hz, 24Hz etc., it is possible to the positive approximate number of the first projection frequency parameter is determined that it is, and then by the described second acquisition frequently
Rate parameter obtains the first image corresponding to the first area as the first frequency acquisition parameter.
（2）Please continue to refer to Fig. 3, specifically comprise the following steps：
Step S301：Judge it is described first projection frequency parameter whether be the second frequency acquisition parameter integral multiple；
Step S302b：When the described first projection frequency parameter is not the integral multiple of the second frequency acquisition parameter, lead to
It crosses the projection brightness that adjusts the projection arrangement and/or adjusts the camera sensitivity of described image harvester, and then by institute
Frequency acquisition is stated to adopt for different from the second frequency acquisition parameter described first from the second frequency acquisition parameter adjustment
Collect frequency parameter.
Wherein, in step S301, it is assumed that the second frequency acquisition parameter is：40Hz, 70Hz, it is determined that described first
Project the integral multiple that frequency parameter is not the second frequency acquisition parameter；
Wherein, in step S302b, by the mistake that the second frequency acquisition parameter adjustment is the first frequency acquisition parameter
Journey, that is, the second frequency acquisition parameter is adjusted make be become first projection the whole approximate number of frequency parameter process,
Wherein, if the second frequency acquisition parameter is less than the described first projection frequency rate parameter, such as：Second frequency acquisition
Parameter is 40Hz, then the second projection frequency parameter can have both been improved, the first projection frequency parameter can also be reduced,
Such as：By reducing the sensitivity of described image harvester or reducing the projection brightness of the projection arrangement, and then extend
The time for exposure of described image harvester makes the second frequency acquisition parameter be reduced to 30Hz by 40Hz, and then by 30Hz
As the first frequency acquisition parameter；Or by improving the sensitivity of described image harvester or improving the throwing
The projection brightness of image device, so reduce described image harvester time for exposure, make the second frequency acquisition parameter by
40Hz rises to 60Hz, then using 60Hz as the first frequency acquisition parameter.
As seen from the above description, since in the embodiment of the present application, first when the projection arrangement projects frequency parameter
It, can also be by adjusting projection arrangement when not being the integral multiple of the second picture-taken frequency parameter of described image harvester
The camera sensitivity of projection brightness or image collecting device, and then be as described the using the second frequency acquisition parameter adjustment
First projection frequency parameter of the one projection whole approximate number of frequency parameter, so reached control described image harvester and projection dress
When the initial time put is synchronous with the end time, more convenient technique effect.
In such a case, it is possible at the time of being identical with the t1 moment by controlling the t2 moment, to ensure
When demonstrate,proving i-th of subgraph of described image harvester acquisition described first image, j-th of subgraph of described first image is
Light filling is carried out by the projection arrangement.
In specific implementation process, can be controlled by system bus the t2 moment and the t1 moment for it is identical when
It carves, such as：Control instruction is sent to described image harvester and projection arrangement simultaneously by system bus, and then fills projection
The projection time put is synchronous with the acquisition time of image collecting device, and since the described first projection frequency parameter is described the
The integral multiple of one frequency acquisition parameter, the projection arrangement a certain cycle end time with described image harvester another
The end time in one cycle is also identical, such as：First projection frequency parameter of the projection arrangement is 60Hz, and described image gathers
First frequency acquisition parameter of device be 30Hz, then, the projection arrangement even cycle the projection end time with it is described
The end time of any collection period of image collecting device is all identical.
Wherein, in step S101, the projection arrangement is according to the 1st to i subgraph when carrying out light filling to first area
The order of picture carries out light filling, and within a light filling cycle, when carrying out light filling to subgraph below, the subgraph of front
As being still in light filling state, and after a light filling end cycle, the projection arrangement carries out light filling to first area
Light gradually cut down.It is so right by first area institute described in image acquisition device in based on step S102
During the first image answered, since the projection frequency corresponding to projection arrangement is higher, so the rate of projection corresponding to projection arrangement
Comparatively fast, so image collecting device often collects a subgraph, corresponding to region all mended by the projection arrangement
Light, so can ensure image acquisition device to the first image in each subgraph obtain light filling, thus reach
Prevent the technique effect of shade occur in the image of acquisition.
As seen from the above description, due in the embodiment of the present application, when the corresponding first projection frequency parameter of projection arrangement
For the first frequency acquisition parameter of image collecting device integral multiple when, synchronized projection device and image collecting device can be passed through
Initial time and the end time ensure image acquisition device each subgraph all mended by the projection arrangement
Light, due to directly controlling the initial time that can realize projection arrangement and image collecting device by system bus at the end of
Between it is synchronous, so reached the more convenient technique effect of operation.
It second, please refers to Fig.4, described at the t1 moment, first area is being carried out based on described image harvester
During Image Acquisition, the first area is carried out with the first projection frequency parameter in a manner that the projection arrangement uses projection
Before light filling, the method further includes：
Step S401：Judge whether the first projection frequency parameter is less than the first frequency acquisition parameter；
Step S402：When the described first projection frequency parameter is less than the first frequency acquisition parameter, the t2 is controlled
Moment is at the time of after the t1 moment.
Wherein, in step S401, since first frequency acquisition can be arbitrary value, such as：30Hz、60Hz、120Hz
Etc., so first frequency acquisition had both been likely less than the first projection frequency and may also be more than the described first projection frequency
Rate.Assuming that first frequency acquisition is：120Hz, then then the first projection frequency parameter is then less than the described first acquisition
Frequency parameter.
Wherein, due to judging that the first projection frequency parameter is joined less than first frequency acquisition in step S401
Number, so illustrate that the acquisition rate of described image harvester is higher than the rate of projection of the projection arrangement, in this case,
The mode that the projection arrangement first passes through projection can be controlled to carry out light filling to the first area, that is, the t1 moment is
At the time of before the t2 moment, to a certain extent and then pass through described image harvester in light filling and gather the first area
The first corresponding image.
When at the time of wherein, before the t1 moment is controlled as the t2 moment, based on the described first projection frequency ginseng
The difference of number and the first frequency acquisition parameter, the t1 moment and the t2 moment are also different, wherein, as long as described in control
First finish time of k-th corresponding of image acquisition period and the throwing during image acquisition device described first image
Second finish time in l-th of projection cycle of image device is identical.
Such as：Assuming that the first projection frequency parameter is 60Hz, the first frequency acquisition parameter is 120Hz, then,
In the complete half period of the projection device, that is, 1/120s and then by described in the acquisition of described image harvester
The first image corresponding to first area can then ensure that described image harvester is gathered corresponding to the described first image
The 1st cycle end time it is identical with the end time in the 2nd cycle corresponding to the projection arrangement, in such case
Under, t2=t1+1/120s.Wherein, k-th of Image Acquisition corresponding during described image harvester acquisition described first image
Second finish time in l-th of projection cycle of first finish time in cycle and the projection arrangement is identical, and described the
One frequency acquisition parameter is more than the described first projection frequency parameter, so can ensure within a certain cycle, described image acquisition
I-th of subgraph one that device is gathered is positioned at after j-th of subgraph that the projection arrangement is projected, Jin Erneng
When enough ensureing i-th of subgraph that described image harvester is gathered, j-th of subgraph of described first image is by described
Projection arrangement light filling, and then guarantee image collecting device acquired image obtains abundant light filling, prevents image from occurring
The technique effect of shade.
Wherein, as a preferred embodiment, when determining the t2 based on t1, it is ensured that the t1 is thrown with described first
The sum of multiple cycles of image device are identical with the sum of a cycle of first harvester with the t2.
As seen from the above description, due in the embodiment of the present application, frequency being projected when the first frequency acquisition parameter is more than first
, can be with the initial time of the asynchronous projection arrangement and image collecting device during rate parameter, only synchronous end time, at this
In the case of kind, it can equally ensure that each subgraph of described image harvester acquisition has all been mended by the projection arrangement
Light, so further reached the more accurate technique effect of light filling when gathering image.
