Embodiment two
Referring to Fig. 3, a kind of step flow chart of the method for shooting of the embodiment of the present invention two is shown, is applied to mobile whole
End, the method can specifically include following steps:
Step 201, at least two buffer queues are constructed；
The embodiment of the present invention will construct buffer queue according to pre-defined rule and carry out image and delay after camera opens preview
It deposits.
Referring to Fig. 2, DSP is set between sensor and ISP, is calculated with this to realize that the multiframe under the environment such as night scene synthesizes
Method carrys out accelerating algorithm processing.It should be noted that being not to require to carry out multiframe synthesis under all scenes, only such as
Under the scene of the darks such as night scene, just need to carry out multiframe synthesis based on external DSP.It specifically, generally can be as follows
It is divided into two kinds of situations:
A, when under highlighted environment, when the viewdata signal of sensor passes through external DSP with no treatment, from taking the photograph
As head sensor is transmitted directly to application processor.
B, it when under night scene environment, when the viewdata signal of sensor passes through external DSP, is saved as preview image
Portion arrives the buffer queue in the DDR (Dual Data Rate, Double Data Rate synchronous DRAM) of DSP.Work as execution
When shooting instruction, directly calculated using the preview image in DDR so that it is subsequent can be by multiple image Data Synthesis
One frame, is then transferred to application processor by dsp interface.
Step 202, current environment parameter is obtained, the environmental parameter includes ambient brightness parameter；
In embodiments of the present invention, it can all go to obtain preview image in any environment and be stored in buffer queue,
To carry out multiframe synthesis improving image quality.
But in practice, it can choose in order not to excessively expend mobile terminal resource and just carry out multiframe when having demand
Synthesis, needs to acquire at this time current environment parameter, such as ambient brightness parameter.
Step 203, current shooting environment is determined using the current environment parameter；
After collecting current environment parameter, so that it may determine current shooting environment using current environment parameter.For example, such as
Fruit is smaller according to ambient brightness parameter, can determine that current shooting environment is night scene.
Step 204, it if the current shooting environment is specified shooting environmental, is followed at least two buffer queue
Ring caches preview image.
After determining current shooting environment, if further determining that the whether specified shooting environmental of the shooting environmental, if
It is such as these specified shooting environmentals of night scene, then buffer queue can be used to start the cycle over caching preview image, after being used for
It is continuous to carry out multiframe synthesis.
Specifically, if can then construct two buffer queues in advance, specifically using the synthesis night scene shooting of 6 frames
It is referred to when a kind of shooting shown in Fig. 4 that data cases schematic diagram, each queue there are 6 pieces respectively in queue A and queue B
Buffer (cache module).Two queues are respectively designated as queue A herein: shooting buffer queue；Queue B: standby caches team
Column.
In the case where in night scene environment and no shooting, the realtime image data of queue A and queue B reception camera
Be cyclically updated together, for example, if having carried out a frame image data, according to from A1~A6~B1~B6~A1 sequence successively
Fill each buffer.
Step 205, when receiving shooting instruction, the preview image of at least two buffer queue is combined, and is based on
Combined preview image synthesizes target image.
The embodiment of the present invention utilizes buffer queue circular buffer preview image before shooting.In this way, if receiving bat
Take the photograph instruction, then carry out multiframe using the preview image that stores in buffer queue and synthesize to obtain target image, it is possible to reduce into
Row multiframe obtains the time of multiple preview images when synthesizing.
In one preferred embodiment of the invention, at least two buffer queue may include the first buffer queue and
Second buffer queue, the step 205 may include following sub-step:
When receiving the first shooting instruction, first buffer queue is locked；
Obtain the preview image in first buffer queue；
First object image is synthesized using the preview image in first buffer queue；
Unlock first buffer queue；
Meanwhile second buffer queue continues to cache preview image.
The embodiment of the present invention grabs multiple image from buffer queue and carries out when responding the first time shooting instruction of user
The synthesis of night scene multiframe.
Assuming that when carrying out night scene shooting, data feelings in the queue A and queue B of queue A and situation such as Fig. 4 in queue B
Shown in condition, wherein be stored with effective image data inside the representative buffer for thering is shade to fill in Fig. 4.After starting shooting
6 frame data in queue A are used to synthesize to external DSP night scene composition algorithm, lock queue A.
Data are locked during algorithm synthesis, in queue A no longer updates, and data continue to be normally carried out circulation in queue B
Caching.It should be noted that normal preview is in the case where no shooting, queue A will not be locked, but it can be with queue B mono-
It is same to be cyclically updated.Assuming that situation in latter two queue of night scene composition algorithm completion such as in the queue A and queue B of Fig. 5
Shown in data cases, continue to have updated 2 frame data in queue B in night scene composition algorithm treatment process.
In one preferred embodiment of the invention, the step 205 can also include following sub-step:
When receiving the second shooting instruction, the preview image in second buffer queue is obtained；
Preview image in second buffer queue is added in the first buffer queue；
Lock first buffer queue；
Second target image is synthesized using the preview image in first buffer queue；
After synthesizing the second target image, first buffer queue is unlocked；
Meanwhile continuing to cache preview image in second buffer queue.
In present example, this step is to carry out night scene multiframe in response to the crawl multiple image shooting instruction of user again
Synthesis.
A kind of shooting situation is that user needs quick continuous several times shooting, after completing upper primary shooting, at once after
It is continuous to be shot next time.
The prior art needs to grab 6 frame images, such as background again in the disposition of the quick continuous several times shooting of user
If describing night scene environment camera frame per second in technology is 20fps, then every frame time 50ms, 6 frames of crawl need minimum 250ms, this
A time be it is quite long, user experience can be seriously affected.
In order to solve problems in the prior art, weight is carried out to the buffer in queue A and queue B in embodiments of the present invention
Group, referring in particular to queue A and queue B situation new after a kind of buffer recombination shown in fig. 6,3 will cached in Fig. 5 queue B
The buffer of frame effective image data is put into the end of queue A, and 3 buffer of the beginning of queue A are then put into queue B's
End.
In this way, directly being taken new in queue A when by executing new shooting instruction again after shooting instruction before completion
6 frame data continue to be given to external DSP night scene composition algorithm and synthesized, then lock new queue A, continue normal to update team
Arrange B.Grab image frames again are not needed, then eliminate the 250ms time for grabbing frame.The embodiment of the present invention is by shortening multiframe synthesis
The mode shot to shot time realizes that multiframe synthesis model is quickly continuously shot, significant increase user experience.
Due to the caching in the embodiment of the present invention and frame mechanism is taken to take frame every time when the shooting of quick continuous several times may be implemented
It is zero time-consuming, while can use newly-increased DSP and carrying out multiframe algorithm process, promotes multiframe algorithm process speed.By excellent
The time for changing the multiframe synthesis shooting (shot to shot) under the scenes such as night scene realizes that multiframe synthesis model is quickly continuously clapped
It takes the photograph, significant increase user experience.
