Obtain the focusing area selected on camera image; According to the depth information of described camera image, determine the region at the agent object place that described focusing area is corresponding; Calculate the profile in the region at described agent object place according to the region at described agent object place, show as focusing frame using described profile.Be described further below in conjunction with embodiment.
Embodiment one:
Fig. 1 shows the realization flow figure of the display packing of the focusing frame that first embodiment of the invention provides, and details are as follows:
In step S101, obtain the focusing area selected on camera image.
Concrete, described camera, including, but not limited to smart mobile phone camera, notebook camera or special camera or video camera, camera obtains the mode of image, include but not limited to that (English full name is Charge-coupled Device to CCD, Chinese full name be charge coupled device) photosensitive part carry out photosensitive acquisition or CMOS (English full name is Complementary Metal-Oxide Semiconductor, and Chinese full name is) the photosensitive acquisition of photosensitive part.
Described camera image, refer to camera take pictures or capture video time the image that obtains.
The focusing area that described camera image is selected can by receiving the determined focusing area of touch instruction of user's input, or also can be the focusing area of other input mode input.
In step s 102, according to the depth information of described camera image, determine the region at the agent object place that described focusing area is corresponding.
Concrete, obtain the mode of the depth information of each pixel in camera image, the depth information that the image using dual camera to obtain determines each pixel can be comprised, the acquisition methods of other depth information can certainly be used, such as use infrared distance measurement to obtain depth information.
According to the region at described focusing area determination agent object place, the depth information of described focusing area can be searched, determine the region at searched agent object place according to this depth information.Further instruction will illustrate in embodiment two to enforcement four.
Agent object in described camera image, refers to the comparatively significant object of the feature being arranged in described camera image, such as can define the feature of some agent objects, as being the comparatively notable feature such as character facial, human limbs action.Except defining the feature of some main agent objects, can also according to the extracting method of conventional agent object, such as the image in webpage, can by the agent object in the markup information determination image of image, by searching and marking corresponding information, thus determine the agent object in image.
Certainly, should not be limited to this, the embodiment of the present invention also comprises the depth information according to the pixel in image, determines the agent object of image, will illustrate in subsequent embodiment.
The region at the place of agent object described in the embodiment of the present invention, namely by after above-mentioned various method determination agent objects, and record the position of described agent object in camera image, described position can represent with coordinate.Can by recording the shape of described agent object, and the key position point of the shape of corresponding record agent object, such as triangle, then only need the position coordinates on record three summits, and for polygon, then need the apex coordinate recording multiple boundary position, and the connected mode on summit, such as which summit with which summit is connected, and the line be connected is straight line or camber line, if camber line, comprise the information such as the radius of curvature of camber line, radian.
In step s 103, calculate the profile in the region at described agent object place according to the region at described agent object place, show as focusing frame using described profile.
Concrete, the profile of described agent object, refers to the background in described agent object and image, i.e. the boundary line of non-agent object.
The calculating of the profile of described agent object, the state information of pixel that can be adjacent with surrounding according to each pixel in agent object is determined.
Such as, the shape supposing each pixel in image is square, so, has four adjacent pixels to be close to it for each pixel.When determining whether described pixel is the profile of agent object, can search centered by described pixel, search the pixel whether four adjacent pixels of this central pixel point are agent object, if have one or more than one neighbor pixel not belong to described agent object, then described central pixel point is the pixel of the profile of agent object.On the contrary, if adjacent four pixels of described and described central pixel point are agent object, then this central pixel point is not the pixel of the profile of agent object.
According to same reason, when the shape of described pixel is other shape, also only need to search pixel centered by this pixel, whether other pixel adjacent with described central pixel point is main object, if there is one or more pixel not to be agent object, then described central pixel point is the profile of agent object.
Because the embodiment of the present invention is by searching the region of the agent object in camera image, determines according to the region of described agent object and showing the profile of described agent object.Make the selection of destination object more accurate, effectively can improve the efficiency of selection to destination object.
Embodiment two:
Fig. 2 shows the realization flow of the display packing of the focusing frame that second embodiment of the invention provides, and details are as follows:
In step s 201, the focusing area selected on camera image is obtained.
In step S202, obtain the depth information of each pixel in camera image.
Concrete, the depth information of described camera image, namely in scene, each pixel of object is relative to the distance of imaging terminal, and described object can the imaging in shooting camera by light reflection for people, tree, automobile, house etc., observable object.The depth information of described image, can be obtained by the method for the depth information of current various computed image, the depth information of each point in object such as can be obtained by laser radar range, also can be found range by zoom, or the mode of multi-base stereo imaging, obtains the depth information of each point in image.Certainly, according to the mode of the dual camera range finding described in the embodiment of the present invention three, the depth information of image can also be obtained, specifically will introduce in the embodiment of the present invention three.
In step S203, according to the threshold range preset and described focusing area, search the pixel that depth information meets described threshold range in the picture.
The threshold range of described setting, the central point that user specifies can be received, and the threshold radius of a depth information is obtained according to described central point and threshold radius, or also can set two threshold boundaries values, by two threshold boundaries value definite threshold scopes, certainly can also pass through setting threshold boundaries, will described threshold boundaries be greater than or less than as set threshold range.The mode of concrete setting threshold scope, will be described in subsequent embodiment.
In step S204, form the region at agent object place according to searched pixel.
When the depth information of the pixel in camera image meets the threshold range set by step S202, then can think that it meets set threshold range requirement.
Certainly, as in the execution mode that the embodiment of the present invention is optimized further, can also comprise and filtration step is carried out to the region at the agent object place of searching, to comprise one of the following two kinds mode in concrete, or comprise two kinds of modes and filter simultaneously.
Mode one:
Whether the region area that the pixel searched described in judgement is formed is greater than default area surface product value;
If described in the region area that forms of the pixel searched be greater than default area surface product value, then form the region at agent object place according to searched pixel.
Wherein, the area surface product value preset, can be described by pixel, such as can set default area surface product value is N number of pixel.Described default area surface product value, relevant with the resolution of camera image, when camera image resolution is larger, then can improve default area surface product value accordingly.
In mode one, the object that the region area of the image obtained filters is, the interference of noise image to main information of other non-main body can be reduced, such as identical or close with subject image depth information object is to the interference of subject image, or due to the interference that the depth information error of calculation is brought, thus improve the accuracy of agent object acquisition further.
Mode two:
Whether the region that the pixel searched described in judgement is formed is continuous print region;
If described in the region that forms of the pixel searched be continuous print region, then form the region at agent object place according to searched pixel.
Equally, for in the noise image existed in camera image, also can be queued up by the continuity of image-region the interference of the interference of noise image to agent object, the pocket that such as identical or close with the depth information of subject image object or the depth information error of calculation are brought.
By the judgement of the main information in region formed pixel, satisfactory, that area is maximum region can be selected as the region at agent object place.
As in a kind of execution mode more optimized of the present invention, mode one and mode two can also be combined, better to filter noise image, obtain agent object more accurately.
In step S205, calculate the profile in the region at described agent object place according to the region at described agent object place, show as focusing frame using described profile.
Step S201, S205 are identical with the step S101 in embodiment one, S103, do not repeat at this.
The embodiment of the present invention is by obtaining the depth information of each pixel in camera image, compared with the threshold range preset by depth information, the pixel being met requirement forms the region at agent object place, calculate the profile of described agent object according to the region at described agent object place, and described profile is shown as focusing frame.The present invention also describes the mode that two kinds are optimized agent object further, thus the further accuracy improving agent object and search.

On the basis of embodiment two, the described focusing area that Fig. 3 shows third embodiment of the invention to be provided be camera automatically search focusing area time, according to the threshold range preset, search the realization flow that depth information meets the pixel of described threshold range in the picture, details are as follows:
In step S301, calculate the mean depth information in described camera image.
Concrete, the mean depth information of described camera image, can average according to the depth information of pixel each in camera image and calculate.
In step s 302, setting described threshold range is the scope being less than described mean depth information, searches the pixel being less than described mean depth information.
According to the mean depth information that step S301 calculates, each pixel in itself and camera image is compared, image can be divided into two parts, the region that a part is formed for the pixel being greater than mean depth information, the region that a part is formed for being less than or equal to mean depth information pixels point.Consider that agent object is general near camera terminal, therefore can by selecting the region being less than or equal to mean depth information pixels point formation to be agent object.By this filter type, be especially applicable to agent object and the distant scene of background.
Certainly, when the region selecting the pixel being greater than mean depth information to form, can using the background object of this subregion as image.
When the agent object obtained comprises multiple, can according to the selection instruction of user, select one of them or several as agent object.
The embodiment of the present invention is on the basis of embodiment two, specifically describe the mean depth information by calculating camera image, according to the depth information of pixel and comparing of mean depth information, screening obtains agent object, simple to operate, and the accuracy rate obtaining agent object is higher.
