Fig. 3 is the schematic diagram one at the interface of finding a view of camera, as shown in figure 3, camera carries out the measuring and calculating area of continuous auto-focusingDomain (namely focusing area) is the central area of screen, and the area of the central area occupies the 1 of whole screen, 4, subject(namely destination object of user's shooting) is located at the upper right corner of central area, namely：Central area is assumed to be A, subjectRegion is assumed to be A1, and the region in central area in addition to subject is assumed to be A2, it is clear that A=A1+A2.
Because when carrying out continuous auto-focusing, the measuring and calculating region of continuous auto-focusing is screen center 1, the area of 4 sizesDomain (namely a-quadrant in Fig. 3), and due to smaller (namely Fig. 3 Zhong A1 areas of subject ratio shared in a-quadrantDomain), continuous auto-focusing processing procedure needs to look after the imaging (namely A2 regions in Fig. 3) of other objects in a-quadrant, leadsIt is still unsharp to cause the subject after continuous auto-focusing is carried out.It is real for this and similar situation, the present inventionApply the continuous auto-focusing scheme that example proposes a kind of improvement.
Fig. 4 is the schematic flow sheet one of the focusing method of the embodiment of the present invention, as shown in figure 4, focusing method is including followingStep：
Step S401, obtain the focusing track for being inputted in the target area in interface of finding a view.
In the embodiment of the present invention, the region of camera shooting is referred to as view area, and the scene in view area is presented on into screenWhen on curtain, the picture on screen is referred to as interface of finding a view, it is seen then that and interface of finding a view is corresponding with view area, namely：Find a view interfaceIt is the picture that view area is presented on screen.
In the embodiment of the present invention, it is assumed that the size at interface of finding a view and terminal screen it is in the same size, certainly, interface of finding a viewSize might be less that the size of terminal screen, namely：Interface of finding a view occupies a part for screen.In order to distinguish interface of finding a viewMain body and background, and consider that main body is normally at the central area at interface of finding a view, using the central area at interface of finding a view as meshRegion is marked, this target area that is to say body region.In one embodiment, target area occupies the 1 of interface of finding a view, 4, whenSo, the size of target area and position not limited to this.
In the embodiment of the present invention, because the size of subject is possible to smaller relative to target area, therefore, in order to moreAccurately subject is focused, target area is refined.Specifically, target area is divided into N number of subregion.In one embodiment, the size all same of every sub-regions in N number of subregion.In another embodiment, N number of subregionIn every sub-regions size it is different or the sizes of part subregion are different.Fig. 5 is the camera of the embodiment of the present inventionFind a view the schematic diagram two at interface, as shown in figure 5,1,4 regions (namely target area) at interface center of finding a view are divided into 5 × 525 sub-regions (namely N=25).It will be appreciated by those skilled in the art that the division of target area is not limited to shown in Fig. 5Mode, can also be divided by other means.
As shown in fig. 6, terminal is learnt from else's experience, region shows current picture, and user carries out the shooting of exact focus as neededObject, pass through touch-screen input and the input trajectory T similar in the reference object track of terminal.Terminal is obtained on input trajectory TEach touch point coordinate value, the coordinate value of each touch point got is compared with the coordinate range of target area,Each touch point in the coordinate range will be dropped into and be defined as the track T2 that focuses, each touch not fallen within the coordinate rangePoint is defined as track T1 outside scope.
Step S402, M sub-regions in target area are determined based on focusing track, and M sub-regions are defined as pairBurnt region.
As shown in fig. 7, target area is divided into N number of subregion, determined per sub-regions by way of coordinate rangePer position of the sub-regions in screen.By the coordinate value and the coordinate model of every sub-regions of the touch point that will be focused on trackEnclose and be compared, from N number of subregion selection include the M sub-regions of the touch point of focusing track, and by the M sub-regionsIt is defined as focusing area.
Step S403, the subject of focusing area is focused.
In the embodiment of the present invention, focusing is carried out to the object in the focusing area and uses Autofocus Technology.From basicFor principle, auto-focusing is segmented into two major classes：One kind is the ranging based on range measurement between camera lens and the target that is takenAuto-focusing, another kind of is the focus detection auto-focusing based on imaging clearly on focusing screen.
Illustrate focus process by taking focus detection auto-focusing as an example below：The focal length of camera is adjusted, obtains different focalThe image at corresponding interface of finding a view；When the definition maximum of the image in the focusing area in the interface of finding a view,Determine current focus focusing focal length corresponding to the focusing area.
Above-mentioned focus detection auto-focusing mainly has contrast method and phase method, wherein：
1) contrast method, this method are to realize auto-focusing by the contour edge of detection image.The profile side of imageEdge is more clear, then its brightness step is bigger, and the contrast between edge scenery and background is bigger in other words.Conversely,Image out of focus, contour edge is smudgy, and brightness step or contrast decline；Out of focus more remote, contrast is lower.Utilize thisPrinciple, two photoelectric detectors are placed on equidistance before and after charge coupled cell (CCD, Charge-coupled Device)Place, by the image of photography thing by light splitting simultaneously into the contrast on the two detectors, exporting its imaging respectively.When twoDuring the absolute value minimum for the contrast difference that detector is exported, illustrate the image planes of focusing just among two detectors, i.e.,Approached with CCD imaging surface, then focusing is completed.
2) phase method, this method are to realize auto-focusing by detecting the offset of picture.One is placed in CCD positionThe waffle slab being made up of parallel lines, lines are in succession printing opacity and light tight.After network board on appropriate location with optical axis symmetricallyPlace two photo detectors.Network board with it is of reciprocating vibration in optical axis vertical direction.When focusing surface overlaps with network board, pass throughThe light of waffle slab printing opacity lines reaches two photo detectors behind simultaneously.And when defocus, light beam can only successively reach twoIndividual photo detector, then there is phase difference between their output signal.Dephased two signals are after processing of circuitControl executing agency to adjust the position of object lens, focusing surface is overlapped with the plane of waffle slab.
In one embodiment, the focusing method is further comprising the steps of：
The focusing area is marked out in the picture corresponding to interface of finding a view.
As shown in figure 8, interface of finding a view includes 4 focusing areas, marked in picture corresponding to interface of finding a view by square frameGoing out focusing area, user can easily know the position where clearly region, wherein, focusing area only is completed to focusInterface of finding a view can be just shown in afterwards, by the quantity of focusing area to prompt whether user currently completes to focus.
Pass through focusing method provided in an embodiment of the present invention so that user, which can predefine, carries out detection zone shape of focusingShape, when terminal is being focused, focusing calculating is carried out according to the shape of focusing area, and prompt user to work as by display interfaceWhether the subject in preceding focusing area focuses, and compared to existing automated process, the focusing method of the present embodiment improvesFocusing levels of precision, meanwhile, reduce process and time that focusing calculates.
As shown in figure 9, in second embodiment provided by the invention, by obtaining the regulation of the area for focusing area,Further accurate focusing area and focusing speed for reference object, it is carried out as follows.
Step S901, obtain the focusing track for being inputted in the target area in interface of finding a view.
Step S902, the M sub-regions in target area are determined based on focusing track.
Step S903, obtain the big minor adjustment behaviour for the subregion for being directed to the touch point comprising focusing track in target areaMake.
In the embodiment of the present invention, because the size of subject is possible to much smaller than focusing area or much larger than focusing areaDomain, therefore, in order to adaptively be focused to subject, the size of focusing area is adjusted.
In the embodiment of the present invention, the big minor adjustment of focusing area is operated based on big minor adjustment to realize, here, sizeRegulation operation includes two classes, and one kind is amplification regulation operation, and another kind of is to reduce regulation operation.In one embodiment, can be withRealize amplification regulation operation by gesture or reduce regulation operation, such as：Kneading operation is carried out by two fingers, is come realNow reduce regulation operation, lock out operation carried out by two fingers, to realize amplification regulation operation, wherein, finger mediate orThe distance of separation characterizes the degree zoomed in or out.Again for example：Regulation is reduced to realize by a finger upward slidingOperation, by a finger slide downward come realize amplification regulation operation, wherein, finger slide up or down apart from tableThe degree zoomed in or out is levied.
It will be appreciated by those skilled in the art that the realization of amplification regulation operation or the diminution regulation operation of the embodiment of the present inventionMode is not limited to this, can also realize by other means, such as long-press left direction button is grasped to realize that amplification is adjustedMake, long-press right direction button reduces regulation operation to realize.
Step S904, operated based on big minor adjustment, it is determined that corresponding zooming parameter.
In inventive embodiments, the big minor adjustment operation based on the focusing area is capable of determining that the focusing area is correspondingZooming parameter.Here, the operational attribute in big minor adjustment operation characterizes zooming parameter.
In one embodiment, kneading operation is carried out by two fingers, reduces regulation operation to realize, pass through twoFinger carries out lock out operation, and to realize amplification regulation operation, finger is mediated or the distance of separation characterizes and reduces parameter or putBig parameter.
In another embodiment, regulation operation is reduced to realize by a finger upward sliding, passes through a handFinger slide downward operates to realize that amplification is adjusted, and the distance that finger slides up or down, which characterizes, reduces parameter or amplification ginsengNumber.
In yet another embodiment, long-press left direction button operates to realize that amplification is adjusted, long-press right direction buttonRegulation operation is reduced to realize, the pressing duration of left direction button or right direction button characterizes amplifying parameters or reduces parameter.
In specific application, it is assumed that zooming parameter E, it is A that focusing area, which carries out the area before big minor adjustment, focusing areaIt is a to carry out the area after big minor adjustment, then is tied to form just like ShiShimonoseki vertical：
A=E × A
Here, when E is more than 0 less than 1, represents and focusing area is contracted to a by A；E be more than 1 when, represent by focusing area byA is amplified to a.
Step S905, based on zooming parameter, by the subregion of the touch point for track of focusing by first area range regulation extremelySecond area scope.
As shown in Figure 10, in the embodiment of the present invention, it is assumed that the scope before the big minor adjustment of focusing area progress is first areaScope (corresponds to area A), then, can be by zooming parameter by original first area range regulation to based on zooming parameterTwo regional extents.Here, second area scope (corresponds to area a) namely focusing area carries out the scope after big minor adjustment.
In the embodiment of the present invention, the regional extent (such as first area scope, second area scope) of focusing area can be withCharacterized by the pixel coordinate of display screen, by taking the scope of first area as an example, first area scope can by (x1, y1) and(x2, y2) is characterized, wherein, (x1, y1) represents the coordinate in the first area scope upper left corner, (x2, y2) represents first area modelEnclose the coordinate in the lower right corner.Similarly, second area scope can be characterized by (x3, y3) and (x4, y4), wherein, (x3, y3) generationThe coordinate in the table second area scope upper left corner, (x4, y4) represents the coordinate in the second area scope lower right corner.
In the embodiment of the present invention, based on the regional extent of zooming parameter regulation focusing area, show focusing areaArea is by turning down greatly or being tuned up by small.
Step S906, the subregion adjusted to the touch point of the focusing track of second area scope is defined as target areaIn focusing area.
Step S907, the subject in focusing area is focused.
In the present embodiment, step S901,902 and step S907 and step S401~S403's in first embodiment is interiorHold identical, therefore will not be repeated here.
Further, sometimes when being focused, the subject in focusing area includes two parts, and a part is userReally want the content shot, and simultaneously non-user wants the content shot to another part, in order to avoid to not usingThe content that family is wanted to be focused is focused, and following steps are still further comprised in step S508, by implementing these stepsRapid realize precisely is focused, specific as follows, as shown in figure 11.
Step S9071, to finding a view, image corresponding to interface carries out feature extraction, obtains characteristic parameter.
In inventive embodiments, feature extraction refers to：The information of each pixel in image is extracted, determines that each pixel isIt is no to belong to a characteristics of image, and the continuous image vegetarian refreshments for belonging to same characteristics of image is classified as one kind.The result of feature extractionThat all pixels point on image is divided into different subsets, these subsets tend to belong to isolated point, continuous curve orContinuous region.The characteristic parameter obtained for image progress feature extraction includes but is not limited to：Edge, angle, region,Ridge.
Step S9072, based on the characteristic parameter extracted, determined in focusing area containing the spy for meeting preparatory conditionLevy the destination object of parameter.
As shown in figure 12, in the embodiment of the present invention, subject for background generally relative to more protruding, therefore, quiltIt is more prominent to take the photograph the profile that the characteristic parameter of object symbolizes., can based on the characteristic parameter extracted based on such understandingTo determine some profile, this profile represents the profile of subject, the coordinate position of each pixel based on the profile, canTo determine position of the subject in the interface of finding a view, by the positional information in interface that the son of determination is found a view with it is rightThe coordinate range in burnt region is compared, and then judges in out-degree Jiao region containing the destination object for meeting preparatory condition.It is optionalGround, characteristic parameter are depth information, based on the depth information of each object in interface of finding a view, determine to wrap in focusing areaDestination object containing qualified depth information, such as：Qualified destination object can be depth information less than specificThe subject of value.
Step S9073, destination object in focusing area is focused.
As shown in figure 12, the destination object for meeting condition is determined by step S9072, to the destination object in focusing areaFocused, because focusing area is that have M sub-regions composition, therefore, by only to containing destination object in M sub-regionsSubregion carry out auto-focusing.
