Select and carry out computing with location Figure 50 0a～500d of all second image frames, and drawn by each second image
Face obtains distant view anchor point, middle scape anchor point and the coordinate position of close shot anchor point.It is understood that,
It is said that in general, select the most in order to carry out the second image frame number of computing, then in subsequent step, scape
The precision of deep depth calculation is the highest.
In step S422, processing unit calculate multiple anchor points at least two second image frames with
Angle between camera lens module 140 to be measured, to obtain an image depth of view information.Wherein, image depth of field letter
Breath comprises distant view depth of view information, middle scape depth of view information, close shot depth of view information.
For example, as shown in Figure 8, base is for photographic imagery concept, with two camera sites respectively
During shooting object, two pictures 810,820 that will be taken the photograph, after the generation picture 830 that coincides, distance
Two imagings 811,821 of pick-up lens object farther out are less with the angle x1 of a fixed point 831, away from
Bigger with the angle x2 of fixed point 831 from two imagings 812,822 of pick-up lens object farther out.According to
This, can pass through this imaging characteristic, is overlapped by multiple multiple pictures taken the photograph with different camera sites,
And according to multiple imagings of same object in the picture that coincides and pick-up lens or the angle of a certain fixed point, to distinguish
Other object in image frame be for remote, in, the relation of close shot, to calculate image depth of view information.
In one embodiment, as it is shown in fig. 7, location Figure 50 0a～500d is that these four pick-up lenss divide
Do not shoot the location figure in the second image frame.Processing unit can be according in Figure 50 0a～500d of location
Each anchor point coordinate position, being coincided by location Figure 50 0a～500d is that a merging positions Figure 50 0e.Based on

Processor), ASIC (application specific integrated circuit, ASIC)
Or one logic circuit implement.Additionally, bin is in order to store various data, e.g. internal memory, hard disk,
Portable disk memory card etc..
Then, step S430 of Fig. 4 is returned to.In step S430, by distant view depth of view information, middle scape
Depth of view information, close shot depth of view information carry out school by close shot corrected value, middle scape corrected value and distant view corrected value
Just, to export a panoramic deep image, panoramic deep image comprises these a little second images after correction.
In step S440, the analysis diagram in the second image in processing unit foundation panoramic deep image,
To calculate the definition of panoramic deep image, and the second image after correction is carried out complementation, mutual to produce one
Mend panoramic deep image, and calculate a depth of field scattergram of complementary panoramic deep image.Wherein, depth of field scattergram
Can the corresponding depth of field rectangular histogram of for example, complementary panoramic deep image or other numerically present point
Butut.
In one embodiment, the second image after processing unit can utilize at least two corrections is carried out mutually
Mend, complementary mode can be ballot method, calculating pixel average or other image can be mended mutually
The algorithm repaid.For example, the second image after processing unit utilizes three corrections carries out complementation, and this
The second image after three corrections all has an identical object；If after this object only corrects at two
The second image in position be identical, then with these two correction after the second image in object's position be
Standard, by the object's position in the second image after another Zhang Jiaozheng, be adjusted to these two corrections after the
Two images are identical.
In step S450, processing unit is by the distant view depth of view information in complementary panoramic deep image and middle scape
Depth of view information carries out a Fuzzy processing, to produce a synthesis segmentation depth map.
By this mode, can make, in the synthesis segmentation depth map of output, there is the object of close shot depth of view information
More highlight, and other picture part systems are fuzzy, and judge whether synthesis by human eye or processing unit
Close shot part in segmentation depth map is correct, in one embodiment, it is judged that mode be by synthesis segmentation scape
Close shot part in deep figure is compared with known actual close shot part, to judge whether to synthesize segmentation scape
Deep figure is less than an error threshold value with the error of actual environment.Such as, the close shot part in segmentation depth map
It is a basketball, and known actual close shot part is a basketball really, then judge the synthesis segmentation depth of field
Figure is less than an error threshold value with the error of actual environment.Thus user can be learnt via complementary panorama deep
Image produced synthesis segmentation depth map, whether its error with actual environment is in acceptable scope
In.
In step S460, processing unit is by remote with one of synthesis segmentation depth map for known depth of view information
Scape picture, scape picture and a close shot picture are compared in one, to produce an analysis result, and utilize aobvious
Show that device (not shown) is to show analysis result.Thus, can determine whether to produce via steps such as correction, complementations
