Image-pickup method provided by the embodiments of the present application, applied to the electricity for including the collaborative work of M image acquisition units
In sub- equipment, reference is as shown in Figure 1, this method includes following process:
S101: when M image acquisition units are in the open state, the M image acquisition units are controlled with asynchronous
Focal modes carry out asynchronous focusing to the first image acquisition region.
Further, in order to enable M image acquisition units to cooperate, to the image of an Image Acquisition image-region into
The acquisition of row stereo-picture, it is optional focal modes that the asynchronous focal modes, which are arranged, meanwhile, M image acquisition units are also wrapped
A synchronous focal modes are included, synchronous focal modes are the synchronous focusing of M image acquisition units, thus realize that stereo-picture acquires,
Since stereo-picture acquisition has been that existing mature technology repeats no more in order to illustrate the succinct of book again.
Specifically corresponding with synchronous focal modes, asynchronous focal modes are the focusing and zoom of M image acquisition units
It is respectively controlled.Wherein, synchronous zoom mode needs M of any moment of the M image acquisition units in focusing process
Focal plane is consistent, could generate stereo-picture, and under asynchronous focal modes, M image acquisition units are in focusing process
Any moment M focal plane it is not identical.
Since M image acquisition units include synchronizing focal modes and asynchronous focal modes, M can be schemed

Member is illustrated below with different embodiments.
Embodiment one:
When M image ability acquisition unit is identical image acquisition units, M image acquisition units it is most short effective
Focal distance is identical, such as is all 2 centimetres, then the entire focal distance range of M image acquisition units is 2 centimetres to infinitely
Far, then the focal distance range an of image acquisition units is set as the partial distance range in entire focal distance range, and M is a
Image acquisition units have M different focus distance range, and M different focus distance range can be overlapped, can not also be overlapped.
Preferably, faster for focusing speed, it is not overlapped and is preferred with M focal distance range, for example, M=3, that is, include that 3 images are adopted
Collect unit, then it, will be according to right to different focus distance institute in order to when the focal distance range of 3 image acquisition units being allowed not to be overlapped
Most short effective focal distance to infinity is divided into 3 equal focal distances of focusing time by the calculating for the focusing time answered
Range, it is possible thereby to realize that focusing time is most short.
Embodiment two:
Because most short effective focal distance is different, then image acquisition units price is different, therefore for save the cost, can be with
It is different using most short effective focal distance in M image acquisition units, there is the following two kinds embodiment:
Embodiment one: it is based on implementation principle similar with previous embodiment one, sets pair of an image acquisition units
Defocus distance range is the partial distance range in entire focal distance range, but according to the most short of each image acquisition units
The focal distance range of each image acquisition units is arranged in effective focal distance range, if any one image acquisition units is at it
There is no at least one focus point in image acquisition region within the scope of the focal distance of setting and then controls its stopping focusing, than
Such as, electronic equipment includes the different image acquisition units of 4 most short effective focal distance, and most short effective focal distance is respectively 2
