The embodiment of the present application one provides a kind of method of IMAQ, and described method is applied in and comprises or be connected with in the electronic equipment of projection arrangement and image collecting device, and described electronic equipment is for example: notebook computer, mobile phone, panel computer etc.
Please refer to Fig. 1, the method for described IMAQ comprises the steps:
Step S101: in the t1 moment, in the time IMAQ being carried out in first area based on described image collecting device, adopt the mode of projection, with the first projection frequency parameter, light filling is carried out in described first area by described projection arrangement;
Step S102: in the t2 moment, by described image collecting device with corresponding the first image in first area described in the first frequency acquisition parameter acquisition relevant to described the first projection frequency parameter, so that described image collecting device is while gathering the i number of sub images of described the first image, the j number of sub images of described the first image is carried out light filling by described projection arrangement, wherein, described t1 moment and described t2 moment are that identical moment or the described t2 moment is the moment after the described t1 moment, and i, j are greater than 1 arbitrary integer and j to be more than or equal to i.
In specific implementation process, can adopt various ways to control described projection arrangement and described image collecting device, when ensureing that described image collecting device gathers the i number of sub images of described the first image, the j number of sub images of described the first image is carried out light filling by described projection arrangement, wherein, one number of sub images of described the first image is for example: a pixel in described the first image, two kinds that enumerate below are wherein introduced, certainly, in specific implementation process, be not limited to following two kinds of situations.
The first, please refer to Fig. 2, and in based on step S101, before light filling being carried out in described first area by the mode of described projection arrangement employing projection with the first projection frequency parameter, described method also comprises the steps:
Step S201: determine corresponding the second frequency acquisition parameter of the t3 moment of described image collecting device before the t1 moment;
Step S202: based on described the second frequency acquisition parameter, described image collecting device is defined as to described the first frequency acquisition parameter at the frequency acquisition in t1 moment.
Wherein, in step S201, the camera photosensitivity of the depth of exposure of first area and image collecting device under normal circumstances, the second frequency acquisition parameter of the corresponding image collecting device of meeting, wherein, the depth of exposure camera sensitivity value higher or image collecting device of first area is higher, and it is faster that image collecting device gathers the described first area corresponding speed of corresponding the second image, and then make described the second frequency acquisition parameter higher.
Wherein, in step S202, based on described the second frequency acquisition parameter, described image collecting device is defined as to described the first frequency acquisition parameter at the frequency acquisition in t1 moment and can be divided into again multiple situation, two kinds that enumerate below are wherein introduced.
(1) please refer to Fig. 3, specifically comprise the steps:
Step S301: judge whether described the first projection frequency parameter is the integral multiple of described the second frequency acquisition parameter;
Step S302a: in the time that described the first projection frequency parameter is the integral multiple of described the second frequency acquisition parameter, determine that described frequency acquisition is the first frequency acquisition parameter identical with described the second frequency acquisition parameter.
Wherein, in step S301, described the first projection frequency parameter is 60Hz under normal circumstances, also a scan period that is projection arrangement is 1/60s, and certainly, described the first projection frequency parameter can be also other value, such as: 50Hz, 70Hz etc., the embodiment of the present application is not restricted.
Wherein, based on the second frequency acquisition parameter of determining in step S201, just can determine whether described the second frequency acquisition parameter is the whole approximate number of described the first projection frequency parameter, for example: if described the second frequency acquisition parameter is: 12Hz, 24Hz etc., just can determine that it is the positive approximate number of described the first projection frequency parameter, and then using described the second frequency acquisition parameter as described the first frequency acquisition parameter, and then obtain corresponding the first image in described first area.
(2), please continue to refer to Fig. 3, specifically comprise the steps:
Step S301: judge whether described the first projection frequency parameter is the integral multiple of described the second frequency acquisition parameter;
Step S302b: in the time that described the first projection frequency parameter is not the integral multiple of described the second frequency acquisition parameter, by adjusting the projection brightness of described projection arrangement and/or adjusting the camera photosensitivity of described image collecting device, and then be the described first frequency acquisition parameter different from described the second frequency acquisition parameter by described frequency acquisition from described the second frequency acquisition parameter adjustment.
Wherein, in step S301, suppose that described the second frequency acquisition parameter is: 40Hz, 70Hz, determine that described the first projection frequency parameter is not the integral multiple of described the second frequency acquisition parameter;
Wherein, in step S302b, be the process of described the first frequency acquisition parameter by described the second frequency acquisition parameter adjustment, namely described the second frequency acquisition parameter is adjusted that to make be the process that becomes the whole approximate number of the first projection frequency parameter, wherein, if described the second frequency acquisition parameter is less than described the first projection frequency rate parameter, for example: described the second frequency acquisition parameter is 40Hz, so both can improve described the second projection frequency parameter, also can reduce described the first projection frequency parameter, for example: by reducing the photosensitivity of described image collecting device or reducing the projection brightness of described projection arrangement, and then extend time for exposure of described image collecting device, make described the second frequency acquisition parameter be reduced to 30Hz by 40Hz, and then using 30Hz as described the first frequency acquisition parameter, or by improving the photosensitivity of described image collecting device or improving the projection brightness of described projection arrangement, and then the time for exposure of reducing described image collecting device, make described the second frequency acquisition parameter rise to 60Hz by 40Hz, then using 60Hz as described the first frequency acquisition parameter.
As seen from the above description, due in the embodiment of the present application, in the time that the first projection frequency parameter of described projection arrangement is not the integral multiple of the second IMAQ frequency parameter of described image collecting device, can also be by adjusting the projection brightness of projection arrangement or the camera photosensitivity of image collecting device, and then be the first projection frequency parameter as the whole approximate number of described the first projection frequency parameter using the second frequency acquisition parameter adjustment, control the initial time of described image collecting device and projection arrangement and end time when synchronous so reached, convenient technique effect.
In this case, can it be the moment identical with the described t1 moment by controlling the described t2 moment, while gathering the i number of sub images of described the first image with the described image collecting device of guarantee, the j number of sub images of described the first image is carried out light filling by described projection arrangement.
In specific implementation process, can it be the identical moment by t2 moment described in system bus control and described t1 moment, for example: by system bus simultaneously to described image collecting device and projection arrangement sending controling instruction, and then synchronizeed the projection time of projection arrangement with the acquisition time of image collecting device, and because described the first projection frequency parameter is the integral multiple of described the first frequency acquisition parameter, described projection arrangement is also identical in the end time in another cycle with described image collecting device in the end time in a certain cycle, for example: the first projection frequency parameter of described projection arrangement is 60Hz, the first frequency acquisition parameter of described image collecting device is 30Hz, so, described projection arrangement is all identical with the end time of arbitrary collection period of described image collecting device in the projection end time of even cycle.
Wherein, in step S101, described projection arrangement is in the time carrying out light filling to first area, to carry out light filling according to the 1st order to i number of sub images, and within a light filling cycle, in the time that the subimage to below carries out light filling, subimage is above still in light filling state, and after a light filling end cycle, described projection arrangement is subdued gradually to the light of light filling that first area carries out.So, in based on step S102, while gathering corresponding the first image in described first area by image collecting device, because the corresponding projection frequency of projection arrangement is higher, so the corresponding rate of projection of projection arrangement is very fast, so image collecting device often collects a number of sub images, its corresponding region is all by described projection arrangement institute light filling, so can ensure that in the first image that image collecting device collects, every number of sub images all obtains light filling, thereby reach the technique effect that occurs shade in the image that prevents from gathering.
As seen from the above description, due in the embodiment of the present application, in the time of the integral multiple of the first projection frequency parameter corresponding to the projection arrangement first frequency acquisition parameter that is image collecting device, can ensure that each subimage of image collecting device collection all carries out light filling by described projection arrangement by the initial time of synchronized projection device and image collecting device and end time, synchronous owing to directly just can realizing initial time and end time of projection arrangement and image collecting device by system bus control, so reached technique effect more convenient to operate.
The second, please refer to Fig. 4, described in the t1 moment, in the time IMAQ being carried out in first area based on described image collecting device, before light filling being carried out in described first area by the mode of described projection arrangement employing projection with the first projection frequency parameter, described method also comprises:
Step S401: judge whether described the first projection frequency parameter is less than described the first frequency acquisition parameter;
Step S402: in the time that described the first projection frequency parameter is less than described the first frequency acquisition parameter, controlling the described t2 moment is the moment after the described t1 moment.
Wherein, in step S401, because described the first frequency acquisition can be arbitrary value, such as: 30Hz, 60Hz, 120Hz etc., also may be greater than described the first projection frequency so described the first frequency acquisition both may be less than described the first projection frequency.Suppose that described the first frequency acquisition is: 120Hz, so described the first projection frequency parameter is less than described the first frequency acquisition parameter.
Wherein, be less than described the first frequency acquisition parameter owing to judging described the first projection frequency parameter in step S401, so illustrate that the acquisition rate of described image collecting device is higher than the rate of projection of described projection arrangement, in this case, can control described projection arrangement and first by the mode of projection, light filling be carried out in described first area, namely the described t1 moment is the moment before in t2 moment, light filling to a certain extent after, then gather corresponding the first image in described first area by described image collecting device.
Wherein, in the time controlling the moment of described t1 moment before being the described t2 moment, based on the difference of described the first projection frequency parameter and described the first frequency acquisition parameter, described t1 moment and described t2 moment are also different, wherein, if control described image collecting device while gathering described the first image first finish time in corresponding k IMAQ cycle identical with second finish time in l projection cycle of described projection arrangement.
For example: suppose that described the first projection frequency parameter is 60Hz, described the first frequency acquisition parameter is 120Hz, so, in the complete half period of described projection device, namely after 1/120s, gather corresponding the first image in described first area by described image collecting device again, can ensure that described image collecting device gathers the end time in corresponding the 1st cycle of described the first image identical with the end time in corresponding the 2nd cycle of described projection arrangement, in this case, t2=t1+1/120s.Wherein, when described image collecting device gathers described the first image, first finish time in corresponding k IMAQ cycle is identical with second finish time in l projection cycle of described projection arrangement, and described the first frequency acquisition parameter is greater than described the first projection frequency parameter, so can ensure within a certain cycle, after the i number of sub images one that described image collecting device gathers is positioned the j number of sub images of described projection arrangement institute projection, and then can ensure i number of sub images that described image collecting device gathers time, the j number of sub images of described the first image is by described projection arrangement light filling, and then reach and ensured that the image that image collecting device gathers obtains abundant light filling, prevent that the technique effect of shade from appearring in image.
Wherein, as a preferred embodiment, in the time determining described t2 based on t1, ensure that described t1 is identical with the one-period sum of described t2 and described the first harvester with multiple cycle sums of described the first projection arrangement.
As seen from the above description, due in the embodiment of the present application, in the time that the first frequency acquisition parameter is greater than the first projection frequency parameter, can asynchronous described projection arrangement and the initial time of image collecting device, the only synchronous end time, in this case, can ensure that equally each subimage of described image collecting device collection all carries out light filling by described projection arrangement, so further reached the more accurate technique effect of light filling in the time gathering image.
