Unit, for identifying the region where destination object from first photo；Determining unit, for the mesh for determining to identify
Mark the distance of object distance camera terminal；Generation unit, for pre-determined distance threshold will to be more than apart from the distance of the camera terminal
Region where the destination object of value, the region of preset strength threshold value is less than as light intensity.
3) generation module 303, it is strong for corresponding region in second photo to be synthesized into light in first photo
Degree is less than the region of preset strength threshold value, the photo that generation shooting is obtained.
Getting the first photo and the second photo, and after determining which region needs light filling, it is possible to by second
The region merging technique of these in photo is into the first photo, and being replaced by these regions in the second photo in the first photo needs light filling
Region, so as to generate a kind of photo for meeting light requirement.
Above-mentioned can be realized by two cameras when the first photo and the second photo is obtained, for example, logical
Cross the first camera to take pictures using common screening-mode, taken pictures by second camera using Flash Mode.It is of course also possible to
It is that the first photo and the second photo are shot by same camera, specifically, first passes through the camera and clap in the normal mode
According to, flash lamp is then opened again, is taken pictures by Flash Mode, other acquisition parameters without adjustment.
Based on above-mentioned camera arrangement, each embodiment of the inventive method is proposed.
As shown in figure 4, the embodiment of the present invention proposes a kind of photographic method, including：
Step 401：The first photo and the second photo are obtained, wherein, first photo and second photo are to same
One region is co-located to shoot what is obtained, and the exposure of second photo is higher than the exposure of first photo；
In view of when taking pictures, often there are the not very good feelings of light in remote object or personage
Condition, for these objects or personage, if being shot using general mode, then these remote objects or personage
Deng will be very unintelligible when display processing on picture.
But, the problem of insufficient light this if solution, light filling directly can be carried out to whole region, but such as
Fruit, for the either higher region of light closely, will result in exposure intensity mistake using if this light filling mode
High the problem of.
In order to solve this problem, in this example, two pictures can be obtained, what this two photos were clapped is that same position is same
Two photos in one region.Wherein, this two photos, have one be than another exposure it is high.
In order to obtain two different photos of depth of exposure, it can be shot by the first camera in general mode and obtain institute
State the first photo；Shot by second camera in Flash Mode and obtain second photo.
That is, shot, shot by another camera using Flash Mode using general mode by a camera,
So that it is the picture for being not added with flash of light to obtain one, another is the picture for having added flash of light.
Assuming that there is a people before the region being taken, behind have under a people, common screening-mode, before people's light
Line is sufficient, but a people below is because, therefore, it is not enough that light understands some apart from camera terminal farther out.In flash lamp
Under pattern, before the light of a people can be excessively sufficient, can also seem excessively white bright, the light of latter one people is then to meet light
Line demand.
Flash intensity for Flash Mode can be according to following rule settings：The exposure of second camera it is bright
Angle value is consistent with the rational values of light of the first camera, so that carrying out light filling to the bad region of light.
Step 402：Determine region of the light intensity less than preset strength threshold value in first photo；
It is not that all scenario is required for carrying out light filling when being shot yet.It therefore, it can pre-set one
Individual trigger mechanism, i.e. can be user when it is determined that being currently needed for light filling, open it is this synthesis light filling pattern, then
Subsequently when being taken pictures, just carried out in the way of light filling is synthesized.
When being shot, it can be two pictures of direct shooting, first then can be shown on camera terminal
Individual picture, then, user can directly click on some region as needing the region of light filling with hand.
Can be user by the way of frame choosing when the region for needing light filling is clicked, frame selects a region, so
Afterwards, synthesis light filling is carried out with regard to the region.Can also be, user taps which this position that then system identification goes out a little represents
Individual main body, identifies the whole region of the main body, it is determined that in the region for needing to merge light filling.Or or, user
A position is clicked, then, region after this position is all as being to need the region of light filling.
In one embodiment, the region where destination object can be identified from first photo, from identification
Identify that light intensity is less than the region of preset strength threshold value in region where the destination object gone out.Or, from described first
The region where destination object is identified in photo, it is determined that distance of the destination object identified apart from camera terminal；By distance
The distance of the camera terminal is more than the region where the destination object of pre-determined distance threshold value, is less than as light intensity default strong
Spend the region of threshold value.
Step 403：By corresponding region in second photo be synthesized in first photo light intensity be less than it is default
The region of intensity threshold, generation shoots obtained photo.
Getting the first photo and the second photo, and after determining which region needs light filling, it is possible to by second
The region merging technique of these in photo is into the first photo, and being replaced by these regions in the second photo in the first photo needs light filling
Region, so as to generate a kind of photo for meeting light requirement.
Above-mentioned can be realized by two cameras when the first photo and the second photo is obtained, for example, logical
Cross the first camera to take pictures using common screening-mode, taken pictures by second camera using Flash Mode.It is of course also possible to
It is that the first photo and the second photo are shot by same camera, specifically, first passes through the camera and clap in the normal mode
According to, flash lamp is then opened again, is taken pictures by Flash Mode, other acquisition parameters without adjustment.
Above-mentioned camera arrangement and method are illustrated with reference to a specific embodiment, it is important to note, however, that
The specific embodiment does not constitute the improper restriction to the application merely to the application is better described.
Specifically, it can in the following way be taken pictures, there is insufficient light in the photo obtained to avoid taking pictures
Region.
For example, when taking pictures, the vertical distance of whole shooting area is detected by dual camera, for positioned at below
Object, often there is light is not good situation.In order to solve this problem, there is camera A's and camera B
In the case of, in order to ensure the balance of light between front and rear object and personage, camera A is taken pictures using general mode, and camera B exposes
Light is more (for example, opening flash lamp), wherein, brightness value and the rational values of light of camera A of camera B exposures keep phase
Symbol；Then, it will be synthesized to after the bad local light filling of light in the photo of camera A shootings, so as to obtain each region
Light all very sufficient images.
The existing place bad in light can be effectively solved through the above way, and many details are difficult to clap clear skill
Art problem.
Further, it is contemplated that be not that light is inadequate sometimes, but destination object is inherently partially dark, for example, such as
Fruit target area is Black people, even if light is normal, can also there is the unclear problem of photo.
In this case, mode the same by the way of is entered when can also be according to above-mentioned shooting distant object object
Row is shot.I.e..In order to ensure the balance of light between front and rear object and personage, camera A is taken pictures using general mode, camera
B exposures are more (for example, opening flash lamp), wherein, brightness value and the rational values of light of camera A of camera B exposures are protected
Hold and be consistent；Then, the position where Black people is carried out being synthesized to after light filling in the photo of camera A shootings, so as to obtain one
Each zonal ray very sufficient image.
First obtained is shot under filming apparatus proposed by the present invention and method, the normal mode for obtaining a same area
Picture, and obtained second picture is shot under Flash Mode, then by the corresponding region in second picture to the first figure
The region that light is unsatisfactory for requiring in piece carries out light filling, to form the picture that a whole figure all meets light requirement.By above-mentioned
Mode solves caused by existing image pickup method the too weak technical problem of subregion light in photo, has reached effective lifting
Shoot the technique effect for the definition for obtaining picture.
