Embodiment
The embodiment of the present application provides a kind of image-pickup method and image collecting device, eliminates the technical problem that mancarried electronic aid of the prior art is difficult to realize capturing fast.
The technical problem that the embodiment of the present application is difficult to realize capturing fast to solve above-mentioned mancarried electronic aid, total thinking is as follows:
The embodiment of the present application carries out asynchronous focusing with asynchronous focal modes to image acquisition region by the multiple image acquisition units in stereoscopic image devices, then the focal plane of any instant of multiple image acquisition units in focusing process is all different, can focus to different distance scope simultaneously, image is clearly arrived in focusing fast, shorten focusing time, thus improve IMAQ speed, to realize quick candid photograph.
In order to better understand technique scheme, below in conjunction with Figure of description and concrete execution mode, technique scheme is described in detail, the specific features being to be understood that in the embodiment of the present application and embodiment is the detailed description to technical scheme, instead of the restriction to technical scheme, when not conflicting, the technical characteristic in the embodiment of the present application and embodiment can combine mutually.
The image-pickup method that the embodiment of the present application provides, is applied in the electronic equipment comprising M image acquisition units collaborative work, and as shown in Figure 1, the method comprises following flow process in reference:
S101: when M image acquisition units is in opening, controls a described M image acquisition units and carries out asynchronous focusing with asynchronous focal modes to the first image acquisition region.
Further, in order to enable M image acquisition units collaborative work, carry out stereo-picture collection to the image of an IMAQ image-region, arranging described asynchronous focal modes is optional focal modes, simultaneously, M image acquisition units also comprises a synchronous focal modes, synchronous focal modes is that M image acquisition units is synchronously focused, thus realizes stereo-picture collection, because stereo-picture collection has been existing mature technology, succinct in order to specification, repeats no more again.
Concrete corresponding with synchronous focal modes, asynchronous focal modes is that the focusing of M image acquisition units and zoom control respectively.Wherein, synchronous zoom pattern needs M focal plane of any instant of M image acquisition units in focusing process consistent, stereo-picture could be generated, and under asynchronous focal modes, M focal plane of any instant of M image acquisition units in focusing process is not identical.
Because M image acquisition units comprises synchronous focal modes and asynchronous focal modes, therefore, the focal modes of M image acquisition units can be switched between synchronous focal modes and asynchronous focal modes.Handoff procedure comprises:
Detection be obtain user for a described M image acquisition units is switched to described rapid image collection the first handover operation or obtain user be used for a described M image acquisition units is switched to described stereo-picture collection the second handover operation, obtain a testing result; When testing result shows to obtain described first handover operation, perform step: control a described M image acquisition units, with asynchronous focal modes, asynchronous focusing is carried out to the first image acquisition region; When testing result shows to obtain described second handover operation, control a described M image acquisition units and with described synchronous focal modes, described first image acquisition region is synchronously focused.
Switched between synchronous focal modes and asynchronous focal modes by M image acquisition units, user's different images in varied situations can be met and gather demand.
In order to improve focusing speed further under asynchronous focal modes, meet the demand that user captures fast, S101 is specially: control a described M image acquisition units and focus at M different focusing distance range, wherein, the individual different focusing distance range of described M forms the whole focusing distance range of M image acquisition units jointly.The focusing process of M image acquisition units can start simultaneously and carry out simultaneously, to improve focusing speed.
Concrete, the shortest effective focusing of M image acquisition units, also can not be identical from can be identical.In specific implementation process, M image acquisition units can be identical image acquisition units, can be also different image acquisition units, be described below with different embodiments.
Embodiment one:
When just collecting unit is identical image acquisition units to M image, the shortest effective focusing of M image acquisition units is from identical, such as be all 2 centimetres, then the whole focusing distance range of M image acquisition units is 2 centimetres to infinity, then the focusing distance range of a setting image acquisition units is the partial distance scope in whole focusing distance range, M image acquisition units has M different focus distance range, M different focus distance range can be overlapping, also can not be overlapping.Preferably, in order to the speed of focusing is faster, with M focusing distance range not overlapping be good, such as, M=3, namely comprises 3 image acquisition units, time then in order to make the focusing distance range of 3 image acquisition units not overlapping, by according to the calculating of different focus apart from corresponding focusing time, by the shortest effective focusing from being divided into the equal focusing distance range of 3 focusing time to infinity, focusing time can be realized thus the shortest.
Embodiment two:
Because the shortest effective focusing is from difference, then image acquisition units price is different, therefore in order to cost-saving, the shortest effective focusing M image acquisition units can be adopted from difference, have the following two kinds execution mode:
Execution mode one: based on the enforcement principle similar to previous embodiment one, the focusing distance range of a setting image acquisition units is the partial distance scope in whole focusing distance range, but the focusing distance range of each image acquisition units is set according to the shortest effective focusing distance range of each image acquisition units, if any one image acquisition units there is no at least one focusing in image acquisition region in the focusing distance range that it sets, control it and stop focusing, such as, electronic equipment comprises 4 effective focusings the shortest from different image acquisition units, the shortest effective focusing is from being respectively 2 centimetres, 10 centimetres, 50 centimetres, 1 meter.The focusing distance range then setting 4 image acquisition units is respectively 2 centimetres to 10 centimetres, 10 centimetres to 50 centimetres, 50 centimetres to 1 meter, 1 meter to infinity.Such as be set as that the image acquisition units A of focusing range 2 centimetres to 10 centimetres there is no at least one focusing of the first image acquisition region at 2 centimetres ~ 10 centimetres, then control image acquisition units A and no longer continue focusing process, to reduce the wasting of resources.
Execution mode two: the focusing distance range not setting each image acquisition units, the focusing distance range of each image acquisition units be himself the shortest effective focusing to infinity, then control each image acquisition units and carry out focusing process from the shortest effective focusing to infinity.To continue to use in execution mode one hypothesis: electronic equipment comprises 4 effective focusings the shortest from different image acquisition units, the shortest effective focusing from being respectively 2 centimetres, 10 centimetres, 50 centimetres, 1 meter.Then the focusing distance range 2 centimetres of 4 image acquisition units is to infinity, and 10 centimetres are arrived infinity, and 50 centimetres to infinity.
In specific implementation process, M be more than or equal to 2 integer, namely electronic equipment at least comprises two image acquisition units, such as, and 2,3,4 etc., therefore, the embodiment of the present application does not limit the number of image acquisition units, be that the situation of two explains the technical scheme in the embodiment of the present application below for image acquisition units, but be not used in restriction the present invention.
Such as, electronic equipment comprises the first image acquisition units and the second image acquisition units, then S101 comprises:
Control described first image acquisition units to focus in first focal range of sowing discord to the second focusing from nearest focusing; Meanwhile, control described second image acquisition units to focus in second focal range of sowing discord to described second focusing from focusing farthest; Wherein, described first image acquisition units from described second focusing to described nearest focusing from the first focusing time and described second image acquisition units from described second focusing to described focusing farthest from the second focusing time equal.
Specifically, the shortest effective focusing of the first image acquisition units and the second image acquisition units from can identical also can not be identical, in order to cost-saving, then the first image acquisition units is that the shortest effective focusing is from shorter image acquisition units, such as, 1 centimetre.Second image acquisition units be the shortest effective focusing from larger image acquisition units, such as 10 centimetres.Then electronic equipment calculates the equal distance value of the focusing time of send as an envoy to the first image acquisition units and the second image acquisition units according to the focusing time of the first image acquisition units and the second image acquisition units.
Same, if electronic equipment also comprises the 3rd image acquisition units, the focusing distance range of each image acquisition units can be less, thus focusing to the first image acquisition areas and the reduction of at least one focus shorter, focusing time can be made shorter.
S102: when obtaining at least one focusing in the first image acquisition region when the first image acquisition units in M image acquisition units, obtain the first image of the first image acquisition region gathered by the first image acquisition units, wherein, the first image acquisition units is the arbitrary image acquisition units in M image acquisition units.
Specifically, each image acquisition units in the focusing process in aforementioned 101 can be the image acquisition units of contrast focusing, also can be the image acquisition units of phase place focusing.
One, when M image acquisition units is the image acquisition units of contrast focusing, when first image acquisition units obtains contrast peak value in focusing distance range, the picture of the first image acquisition region is the most clear, then the first image acquisition units gathers the picture of current first image acquisition region is the first image, simultaneously, other image acquisition units except the first image acquisition units or also can not there is no contrast peak value and (continue to use execution mode in the embodiment one of aforementioned S101 and embodiment two for the moment in focusing distance range, except other image acquisition units of the first image acquisition units can not obtain contrast peak value, when continuing to use the execution mode two in previous embodiment two, other image acquisition units going out the first image acquisition units also there is no contrast peak value).
Two, when M image acquisition units is the image acquisition units of phase place focusing, by calculating the phase place of two focusings, accurate focusing is calculated.Judge that focus is to the front or to the rear according to phase difference, with the distance between moving lens and photosensitive imaging module.Thus the first image acquisition units can obtain a focusing fast in focusing distance range, when an acquisition focusing, the picture that first image acquisition units gathers current first image acquisition region is the first image, other image acquisition units then can not obtain a focusing or also there is no a focusing (continues to use execution mode in the embodiment one of aforementioned S101 and embodiment two for the moment, except other image acquisition units of the first image acquisition units can not obtain contrast peak value, when continuing to use the execution mode two in previous embodiment two, other image acquisition units going out the first image acquisition units also there is no contrast peak value).
Further, in order to economize on resources, when the first image acquisition units obtains at least one focus of the first image acquisition region, M-1 the image acquisition units controlled except described first image acquisition units is in stopping focusing state.
