The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings the panorama shooting method, device and imaging device of the embodiment of the present invention are described.
Fig. 1 is a kind of flow diagram of panorama shooting method provided by the embodiment of the present invention.
As shown in Figure 1, this approach includes the following steps：
Step 101, during pan-shot, the movement speed of detection imaging equipment.
The method of the present embodiment can be applied to imaging device, and imaging device includes the sense being made of multiple sensitive pixel elements

The mode of identical time for exposure exports original pixels information, and exports to each photosensitive pixel in same feeling pixel unit original
Pixel Information calculates average value, so that the pixel value for the merging pixel unit information that same sensitive pixel elements obtain reduces,
To improve the processing speed of first object image, Fig. 2 is another kind panorama shooting method provided by the embodiment of the present invention
Flow diagram.
As shown in Fig. 2, this method may comprise steps of：
Step 201, during pan-shot, the movement speed of detection imaging equipment.
It can refer to the step 101 in an embodiment, repeated no more in the present embodiment.
Step 202, if movement speed is higher than threshold velocity, each sensitive pixel elements in sensitive pixel elements array is controlled and are adopted
It is synchronized and is exposed with the identical time for exposure, to obtain the original pixels information of each photosensitive pixel output in each sensitive pixel elements.
In the embodiment of the present invention, belong in the photosensitive pixel of same sensitive pixel elements include at least one long exposing pixels,
Exposing pixels and an at least short exposure pixel at least one, wherein when long exposing pixels refer to photosensitive pixel corresponding exposure
Between be the long time for exposure, middle exposing pixels refer to that the photosensitive pixel corresponding time for exposure is middle time for exposure, short exposure pixel
Refer to that the photosensitive pixel corresponding time for exposure is short exposure time.And in embodiments of the present invention, in imaging device work,
Long exposing pixels, middle exposing pixels and short exposure pixel refer to long exposing pixels, middle exposure using the synchronous exposure of identical time for exposure
Light pixel and short exposure pixel use corresponding exposure time, synchronize exposure in same frame image imaging process.But this
In the synchronous exposure that describes, be not limited to the beginning time for exposure phase of long exposing pixels, middle exposing pixels and short exposure pixel
Together, it is identical to be also not limited to the end time for exposure, but says, the exposure of long exposing pixels, middle exposing pixels and short exposure pixel
Process is for being imaged same frame image.
Specifically, when imaging device movement speed is higher than threshold velocity, imaging device controls sensitive pixel elements first
The synchronous exposure of the long exposing pixels in each sensitive pixel elements, middle exposing pixels and short exposure pixel in array, and be arranged
The identical time for exposure, so that each sensitive pixel elements in sensitive pixel elements array will export after end exposure
Multiple original pixels information under the identical time for exposure.For example, when each sensitive pixel elements include：1 long exposure picture
When element, 2 middle exposing pixels, 1 short exposure pixel, each sensitive pixel elements in sensitive pixel elements array will export four
A original pixels information, i.e., 2 originals that 1 original pixels information of 1 long exposing pixels output, 2 middle exposing pixels export
Beginning Pixel Information and 1 and the output of short exposure pixel 1 original pixels information, and 4 original pixels information are in identical exposure
It is obtained under between light time.
Step 203, merging is calculated to the original pixels information of photosensitive pixel each in same sensitive pixel elements output

The original pixels information of each photosensitive pixel output calculates average value in one sensitive pixel elements, using the average value being calculated as
The merging Pixel Information of the sensitive pixel elements, the corresponding merging Pixel Information of each sensitive pixel elements similarly can be obtained
The corresponding merging Pixel Information of all sensitive pixel elements in sensitive pixel elements array.
Still with above-mentioned example, four original pixels information of sensitive pixel elements output, i.e., 1 long exposure picture are marked
1 original pixels information of element output, 2 original pixels information of 2 middle exposing pixels output and 1 and short exposure pixel
Output 1 original pixels information be respectively：R1, R2, R3 and R4, then the merging Pixel Information of the sensitive pixel elements be：(R1
+ R2+R3+R4)/4, the pixel size for the merging Pixel Information that sensitive pixel elements obtain is reduced, subsequent output the can be improved
The speed of one target image.
In turn, according to the exportable first object image of multiple merging Pixel Informations being calculated.It is photosensitive by reducing
The pixel size for the merging Pixel Information that pixel unit obtains improves the speed of output first object image.
Step 204, spliced according to first object image, obtain panoramic picture.
Specifically, according to obtained multiframe first object image, according to the genesis sequence of multiframe target image, to multiframe
One target image is spliced, will be same or similar in the first object image of consecutive frame as a kind of possible implementation
Part merge splicing, the splicing of first object image is realized, to obtain panoramic picture.
In the embodiment of the present invention, when imaging device movement speed is higher than threshold velocity, sensitive pixel elements array is controlled
In multiple original pixels information for being exposed using the identical time for exposure of each photosensitive pixel output, to same sensitive pixel elements
In the original pixels information of each photosensitive pixel output calculate average value, using the average value being calculated as merging Pixel Information,
First object image is exported according to multiple merging Pixel Informations, reduces the picture for the merging Pixel Information that sensitive pixel elements obtain
Plain size improves the speed of output first object image, improves the formation efficiency of panoramic picture, combined panorama sketch
The image quality of picture.
In a upper embodiment, after synchronous exposure, output is the multiple original images exposed using the identical time for exposure
Prime information, and average value is calculated to the original pixels information of output, it obtains merging Pixel Information, thus the merging reduced
Number of pixels, that is, reduce the resolution ratio of first object image, so that the combined coefficient of first object image is improved, as another
It is multiple original under different exposure time can also to control the output of sensitive pixel elements array for a kind of possible implementation
Pixel Information, and according to the original pixels information under different exposure time, merging Pixel Information is calculated, purpose is also to reduce
Obtained merging number of pixels, to improve the combined coefficient of first object image.
For this purpose, the embodiment of the present invention proposes the possible implementation of another panorama shooting method, Fig. 3 is the present invention
The flow diagram of another panorama shooting method provided by embodiment, as shown in figure 3, this method comprises the following steps：
Step 301, during pan-shot, the movement speed of detection imaging equipment.
Step 302, if movement speed is higher than threshold velocity, control sensitive pixel elements array output is respectively at different exposures
Multiple original pixels information under between light time.
In the embodiment of the present invention, belong in the photosensitive pixel of same sensitive pixel elements include at least one long exposing pixels,
Exposing pixels and an at least short exposure pixel at least one, wherein long time for exposure>The middle time for exposure>Short exposure time is that is, long
The long time for exposure of exposing pixels is greater than the middle time for exposure of middle exposing pixels, and the middle time for exposure of middle exposing pixels is greater than short
The short exposure time of exposing pixels.In imaging device work, long exposing pixels, middle exposing pixels and short exposure pixel are synchronous to expose
Light, it is synchronous to expose the exposure progress for referring to that the exposure progress time of middle exposing pixels and short exposure pixel is located at long exposing pixels
Within time.
Specifically, long exposing pixels can be controlled first to start to expose at first, during the exposure of long exposing pixels, then
Exposing pixels and short exposure pixel exposure in control, wherein the exposure deadline of middle exposing pixels and short exposure pixel answers
Before the exposure deadline identical or positioned at long exposing pixels as the exposure deadline of long exposing pixels；Alternatively, control length
Exposing pixels, middle exposing pixels and short exposure pixel start simultaneously at exposure, i.e., long exposing pixels, middle exposing pixels and short exposure
The exposure initial time of light pixel is identical.In this way, long exposure, middle exposure and short exposure are successively carried out without controlling pixel unit array, it can
Reduce the shooting time of target image.
Specifically, imaging device controls the long exposure in each sensitive pixel elements in sensitive pixel elements array first
The synchronous exposure of pixel, middle exposing pixels and short exposure pixel, wherein the long exposing pixels corresponding time for exposure is initial long exposure
Time, middle exposing pixels corresponding time for exposure are the time for exposure in initial, and the short exposure pixel corresponding time for exposure is initial
Short exposure time, initial long time for exposure, initial middle time for exposure and initial short exposure time are pre-set.Exposure
After, output is respectively at multiple under different exposure time by each sensitive pixel elements in sensitive pixel elements array
Original pixels information.
Step 303, in same pixel unit, the original pixels information of long exposing pixels, the original of short exposure pixel are chosen
The original pixels information of beginning Pixel Information or middle exposing pixels.
In the embodiment of the present invention, in same sensitive pixel elements, the original pixels information of long exposing pixels, short exposure are chosen
The original pixels information of light pixel or the original pixels information of middle exposing pixels, i.e., from the original pixels information of long exposing pixels,
In the original pixels information of short exposure pixel or the original pixels information of middle exposing pixels, an original pixels information is chosen,
It is exactly that time for exposure identical original pixels information is chosen from same sensitive pixel elements.
For example, when including 1 long exposing pixels, 2 middle exposing pixels, 1 short exposure picture in a sensitive pixel elements
Element, and the original pixels information of long exposing pixels is 80, the original pixels information of two middle exposing pixels is 255, short exposure picture
Element original pixels information be 255 when, due to 255 be original pixels information the upper limit, middle exposing pixels and short exposure picture
Plain overexposure, cannot choose as original pixels information, and therefore, selection can be believed for the original pixels of long exposing pixels
Breath：80.Similarly, if long exposing pixels and short exposure pixel exposure are excessive, and the exposure of middle exposing pixels is normal, then the exposure chosen
Identical original pixels information is the original pixels information of middle exposing pixels between light time, and by the original image of two middle exposing pixels
Prime information averaged obtains and merges Pixel Information.
It is to be appreciated that being described in the embodiment of the present invention includes 4 photosensitive pixels in a sensitive pixel elements,
By synthesis, so that 4 photosensitive pixel values synthesize to obtain a photosensitive pixel value, that is to say, that so that being obtained after synthesis photosensitive
Number of pixels is reduced, and is the 1/4 of former photosensitive pixel number, so that image resolution ratio reduces.
Step 304, according to the original pixels information of selection and long time for exposure, middle time for exposure and short exposure time
Between exposure ratio, the merging Pixel Information of first object image is calculated.
Still with above-mentioned example, it is assumed that the exposure between long time for exposure, middle time for exposure and short exposure time, which is compared, is：
16:4:1, then merging Pixel Information is：80*16=1280.
Since the upper limit of original pixels information in the prior art is 255, by the original pixels information according to selection, and
Exposure ratio between long time for exposure, middle time for exposure and short exposure time, is calculated the merging pixel of first object image
Information can obtain high dynamic range images with extended dynamic range, to promote the imaging effect of first object image.
In turn, according to Pixel Information is merged, first object image is exported.
For example, including 1 long exposing pixels, 2 middle exposing pixels, 1 short exposure pixel in each sensitive pixel elements
When, the original pixels information of unique long exposing pixels is the merging Pixel Information of long exposure, 2 middle exposing pixels it is original
The sum of Pixel Information is the middle merging Pixel Information exposed, and the original pixels information of unique short exposure pixel is short exposure
Merging Pixel Information；When in pixel unit including 2 long exposing pixels, 4 middle exposing pixels, 2 short exposure pixels, 2
The sum of original pixels information of a long exposing pixels is the merging Pixel Information of long exposure, the original image of 4 middle exposing pixels
The sum of prime information is the middle merging Pixel Information exposed, and the sum of original pixels information of 2 short exposure pixels is short exposure
Merging Pixel Information.In this way, merging Pixel Informations of multiple long exposures of entire sensitive pixel elements array, more can be obtained
Merging Pixel Information, the merging Pixel Information of multiple short exposures of a middle exposure.
Then, according to the time for exposure of selection identical original pixels information, such as the long exposure picture chosen in the present embodiment
The original pixels information of element obtains the merging Pixel Information of long exposure, and each sensitive pixel elements correspond to a long exposure
Merge Pixel Information, according to multiple merging Pixel Information, that is, exportable first object images.
Further, for further improve first object image image quality, long exposing pixels, middle exposing pixels and
It, can after short exposure pixel synchronizes exposure according to initial long time for exposure, initial middle time for exposure and initial short exposure time respectively
To calculate long exposure histogram, the original exported according to short exposure pixel according to the original pixels information of long exposing pixels output first
Beginning Pixel Information calculates short exposure histogram, and initially the long time for exposure obtains correcting long exposure according to long exposure histogram modification
Time obtains amendment short exposure time according to the initial short exposure time of short exposure histogram modification.Then, then long exposure picture is controlled
Plain, middle exposing pixels and short exposure pixel are respectively according to amendment long time for exposure, initial middle time for exposure and when correcting short exposure
Between synchronous exposure.Wherein, makeover process not settles at one go, but imaging device needs to carry out the synchronous exposure of multiple long, medium and short
Light, after synchronous exposure each time, imaging device can continue to repair according to the long exposure histogram and short exposure histogram of generation
Just long time for exposure and short exposure time, and corrected when exposing next time using last moment the amendment long time for exposure,
Amendment short exposure time and original middle time for exposure synchronize exposure, continue to obtain long exposure histogram and short exposure histogram
Scheme, so in cycles, up to there is no deficient exposure region, short exposure histogram are corresponding in the corresponding image of long exposure histogram
There is no until overexposure region in image, the amendment long time for exposure and amendment short exposure time at this time is that final amendment is long
Time for exposure and amendment short exposure time.Further according to long exposing pixels, middle exposing pixels and short exposure pixel after end exposure
Output carries out the calculating of first object image, and the calculation is identical as the calculation in a upper embodiment, herein no longer
It repeats.
Wherein, long exposure histogram can be one or more.It, can be according to all length when long exposure histogram is one
The original pixels information of exposing pixels output generates one long exposure histogram.It, can be to length when long exposure histogram is multiple
Exposing pixels divide region, and generate one long exposure directly according to multiple long original pixels letter elements for exposing pictures in each region
Fang Tu, in this way, multiple regions correspond to multiple long exposure histograms.The effect for dividing region is can to promote modified length each time
The accuracy of time for exposure accelerates the amendment process of long time for exposure.Similarly, short exposure histogram can be one or more
It is a.When short exposure histogram is one, the original pixels information that can be exported according to all short exposure pixels generates a short exposure
Light histogram.When short exposure histogram is multiple, region can be divided to short exposure pixel, and according to multiple in each region
The original pixels information of short exposure pixel generates a short exposure histogram, in this way, multiple regions correspond to multiple short exposure histograms
Figure.The effect for dividing region is can to promote the accuracy of modified short exposure time each time, accelerates repairing for short exposure time
Positive process.
Step 305, spliced according to first object image, obtain panoramic picture.
In the panorama shooting method of the embodiment of the present invention, when imaging device movement speed is higher than threshold velocity, control sense
The synchronous exposure of each sensitive pixel elements in light pixel cell array, and export be respectively at it is multiple original under different exposure time
Pixel Information, and in same sensitive pixel elements, choose the original pixels information of long exposing pixels, middle exposing pixels it is original
The original pixels information of Pixel Information and short exposure pixel, according to the original pixels information of selection and long time for exposure, middle exposure
Exposure ratio between light time between short exposure time, is calculated merging Pixel Information, exports to obtain according to Pixel Information is merged
First object image.By from same sensitive pixel elements, choosing time for exposure identical original pixels information, and closed
And obtain merging Pixel Information, the pixel quantity after merging in sensitive pixel elements array is reduced, first object figure is reduced
As generating the time expended, improves formation efficiency and combined generation quality.
In above-described embodiment, when describing imaging device movement speed higher than threshold velocity, the generating mode of panoramic picture,
And in practical application, the movement speed of imaging device is variation, and the movement speed of imaging device may also be below or be equal to threshold
It is worth speed, for this purpose, based on the above embodiment, the embodiment of the invention provides the possible realization sides of another panorama shooting method
Formula, Fig. 4 is the flow diagram of another panorama shooting method provided by the embodiment of the present invention, as shown in figure 4, this method packet
Containing following steps：
Step 401, during pan-shot, the movement speed of detection imaging equipment.
Step 402, judge whether movement speed is higher than threshold velocity, if so, step 406 is executed, if it is not, executing step
403。
Specifically, during imaging device photographing panorama picture, the movement speed of imaging device could possibly be higher than threshold value
Speed, it is also possible to be less than or equal to threshold velocity, the movement speed of imaging device is different, and imaging device controls sensitive pixel elements
Exposure method used by array is different, in the present embodiment, when the movement speed of imaging device is higher than threshold velocity, executes step
Rapid 406, when the movement speed of imaging device is less than or equal to threshold velocity, execute step 403.
Step 403, each sensitive pixel elements in sensitive pixel elements array are controlled, different exposure times progress is respectively adopted
Multiple exposure.
Specifically, during pan-shot, each sensitive pixel elements in sensitive pixel elements array is controlled and are respectively adopted
Different exposure times carry out multiple exposure, according to each exposure time, the original pixels letter of the corresponding different exposure times of output
Breath.
Step 404, the original pixels information exported according to sensitive pixel elements array with photosensitive pixel each when single exposure,
Generate a frame original image.
Specifically, according to different exposure times, for the original pixels information of output corresponding under exposure time each time,
It is synthesized, generates corresponding frame original image and obtain the multiframe original image under different exposure times in turn.
Step 405, the original image generated using the exposure of different exposures is synthesized, obtains the second target image.
Second target image refers to the target image generated according to the original pixels information not synthesized, also
It is to say in the second target image, image resolution ratio is identical with the resolution ratio of the sensitive pixel elements array of imaging device, so that the
The image detail of two target images is more preferable, and picture quality is high.After with different exposure shoot multi-frame images, to multiple image
It is synthesized, to obtain second target image.
Step 406, the synchronous exposure of each sensitive pixel elements in sensitive pixel elements array is controlled, to obtain each photosensitive pixel
The original pixels information of each photosensitive pixel output in unit.
Step 407, the original pixels information exported according to photosensitive pixel each in same sensitive pixel elements is calculated the
One target image.
Specifically, step 406-407 can refer to the step 102-103 in Fig. 1 corresponding embodiment, and principle is identical, herein not
It repeats again.
Step 408, interpolation processing, the resolution ratio and second of the first object image after interpolation are carried out to first object image
The resolution match of target image.
Specifically, first object image is exported according to merging Pixel Information, that is to say, that first object image
Resolution ratio reduce, it is therefore desirable to by first object image carry out difference processing so that the first object image obtained after difference
Resolution ratio and the second target image resolution match.
For example, then being carried out original if the corresponding image resolution ratio of original pixels information is 200,000 pixels when not merging
After pixel combination, merging the corresponding first object image resolution ratio of Pixel Information is then 50,000 pixels, after the completion of pan-shot,
It needs to carry out difference to first object image, the resolution ratio of first object image is increased to 200,000 pixels from 50,000 pixel value differences,
So that the resolution match of first object image and the second target image.
Step 409, first object image and the second target image are spliced, obtains panoramic picture.
Specifically, the first object image that difference is handled is spliced with the second target image, to obtain dynamic
Range height and the higher panoramic picture of quality.
