Abstract
The invention discloses HDR image pickup methods, filming apparatus and the mobile terminals and readable storage medium storing program for executing of a kind of shooting of multi-cam.The HDR image pickup methods include：Step 1：By multiple cameras using different exposure parameters, shooting is carried out at the same time to Same Scene, obtains multiple normal images of different exposure values；Step 2：Multiple normal images by HDR algorithms are synthesized, export HDR image.The HDR image pickup methods can be applied to the shooting of moving object and the shooting of HDR videos.
Description
Technical field
The present invention relates to the HDR image pickup methods of field of photography more particularly to a kind of multi-cam, filming apparatus and movement eventually
End and readable storage medium storing program for executing.
Background technology
The cameras of the mobile terminals such as the dynamic range of imaging sensor, mobile phone is limited in big light than being clapped under environment
When taking the photograph, can not normal exposure be carried out to highlight area and low smooth region simultaneously, such as：If camera carries out just highlight area
Often exposure, then low smooth region will owe to expose, is too dark；If camera carries out normal exposure to low smooth region, then specular
It domain will overexposure, too bright.
To solve the above-mentioned problems, HDR（High dynamic range）Technology is widely applied.HDR technologies are a kind of images
Treatment technology, by the way that several normal images of Same Scene under different exposure values are synthesized, with obtain highlight area and
The HDR image of the low equal normal exposure in smooth region, such as：Camera carries out normal exposure to highlight area, obtains first and commonly schemes
Picture, then normal exposure is carried out to low smooth region, the second normal image is obtained, then the first normal image and the second normal image
In respective region of normal exposure extract and synthesized, obtain HDR image.HDR technologies are when in use, it is desirable that scene shot
It is static, therefore the shooting of moving object and the shooting of HDR videos can not be applied to, moreover, in the case of night scene or half-light, also
It needs to carry out fixing camera using tripod with stabilization.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of HDR image pickup methods, the filming apparatus of multi-cam shooting
With mobile terminal and readable storage medium storing program for executing.The HDR image pickup methods and filming apparatus can be applied to the shooting of moving object and HDR is regarded
The shooting of frequency.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of HDR image pickup methods of multi-cam, including：
Step 1：By multiple cameras using different exposure parameters, shooting is carried out at the same time to Same Scene, obtains different exposures
Multiple normal images of value；
Step 2：Multiple normal images by HDR algorithms are synthesized, export HDR image.
Further, in step 1, multiple normal images are carried out using different aperture sizes and identical time for exposure
Shooting obtains.
Further, in step 1, multiple cameras are shot in same camera plane.
Further, step 2 includes：
Step 2.1：Corresponding each pixel in multiple normal images of aliging；
Step 2.2：Obtain respective region of normal exposure in multiple normal images；
Step 2.3：The region of normal exposure of acquisition is synthesized, exports HDR image.
A kind of HDR filming apparatus of multi-cam, including：
Taking module, for multiple cameras using different exposure parameters, to be carried out at the same time Same Scene shooting, obtained not
With multiple normal images of exposure value；
HDR modules for multiple normal images to be synthesized by HDR algorithms, export HDR image.
Further, multiple cameras have different aperture sizes and identical time for exposure.
Further, multiple cameras are located in same camera plane.
Further, HDR modules include：

A kind of mobile terminal, the HDR filming apparatus including above-mentioned multi-cam.
A kind of readable storage medium storing program for executing, is stored thereon with computer program, when which is executed by processor, realizes
The HDR image pickup methods of above-mentioned multi-cam.
The present invention has the advantages that：Multiple cameras are used different exposure parameters by the HDR image pickup methods, right
Same Scene is carried out at the same time shooting, obtains multiple normal images of the different exposure values of Same Scene, then to multiple common figures
As carrying out HDR algorithm synthesis, the HDR image of scene shot is obtained, since all normal images were clapped in the same time
Acquisition is taken the photograph, shooting time is short, can capture the HDR image of moving object and the frame as HDR videos, can be applied to transport
The shooting of animal body and the shooting of HDR videos.
