Specific embodiment
In below describing, in order to illustrate rather than in order to limit it is proposed that the tool of such as particular system structure, technology etc
Body details, thoroughly to understand the embodiment of the present invention.However, it will be clear to one skilled in the art that not having these concrete
The present invention can also be realized in the other embodiments of details.In other situations, omit to well-known system, device, electricity
Road and the detailed description of method, in order to avoid unnecessary details hinders description of the invention.
Fig. 1 shows the structural representation of the photographic head for recording VR video provided in an embodiment of the present invention, in order to just
In explanation, illustrate only part related to the present embodiment.
With reference to Fig. 1, this photographic head include camera lens 11, the lens base 12 supporting camera lens 11, imaging sensor 13 and and
The circuit base plate 14 of imaging sensor 13 electrical connection.Wherein, camera lens 11 is used for assembling light, projects to image forming medium
Surface, that is, project imaging sensor 13 surface；Lens base 12 is used for supporting camera lens 11, plays the effect of fixed lens 11；
Imaging sensor 13 is image forming medium, and it is centrally located on the optical axis of camera lens 11, for projecting its surface by camera lens 11
Optical signal (image) be converted to the signal of telecommunication, be implemented as picture, imaging sensor 13 press species divide, including but not limited to electric charge coupling
Clutch part (Charge Couple Device, CCD) sensor and complementary metal oxide semiconductors (CMOS) (Complementary
Metal Oxide Semiconductor, CMOS) sensor；Circuit base plate 14 is electrically connected with imaging sensor 13, main use
In the electric signal transmission exporting imaging sensor 13 to photographic head rear end, realize image output.
It is readily apparent that, except each modular construction of the photographic head shown in Fig. 1, the shooting involved by the embodiment of the present invention
Head, according to the difference of its species or function, not shown in Fig. 1, can also include but is not limited to：For filtering unnecessary optical band
Light filter；Mobile for driving camera lens 11, make camera lens 11 project clearly image to the motor of imaging sensor 13；For controlling
Motor processed moves, thus promoting camera lens 11 to realize the motor driving chip of auto-focusing, etc..
For the ease of understanding the technical scheme of the embodiment of the present invention, next the human eye related to the embodiment of the present invention is regarded
Feel that characteristic illustrates：
For human eye, two eyes its just as two parallel camera lenses, each camera lens has independent rated capacity.
When human eye is seen toward dead ahead, (i.e. areas imaging, the object outside the angle of visual field will for its angle of visual field (Field of View, FOV)
Cannot be imaged) level angle be about 122 degree (as shown in Fig. 2 (a)), about 120 degree of vertical angle is (as Fig. 2 (b) institute
Show), among this, the level angle of the higher region of resolution of eye (i.e. the taper body vision of human eye) is about at 60～90 degree
Between, vertical angle is about at 60 degree about；And (i.e. the rhabodoids of human eye regard in remaining region relatively low region that is resolution of eye
Feel), in this region, human eye can only distinguish moving object or the profile of identification object, and cannot see object detail clearly, quite
In usually said remaining light.
Based on the above explanation to human-eye visual characteristic, the mirror employed in existing photographic head set forth further below
The characteristic of head：
Photographic head in traditional consumer electronics product, the camera lens that it is used is mostly standard lens, as Fig. 3 institute
Show, the image height of such lens imaging and the angle of visual field increase by a year-on-year basis, thing in each unit angle of visual field is high and its image height of imaging it
Ratio is identical, and in Fig. 3, the angle of visual field of this standard lens is about 78 degree.Due to the broader angle of view of VR video invitation, because
This, to improve the angle of view, can only increase the size of imaging sensor, this can lead to the volume Manufacturing cost of photographic head
All increase.Meanwhile, as described above, human eye vision is in fact divided into taper body vision and shaft-like body vision, and standard lens exist
Its imaging center is the same with the image analysis power at imaging edge, even if therefore having reached wider camera lens using standard lens
The angle of visual field, but the actual vision of user cannot fully perceive the image analysis power at imaging edge, and this undoubtedly also result in one
Plant imaging to waste.
Additionally, for wide-angle lens, even for fish eye lens, as shown in figure 4, the increasing of the image height of such lens imaging
If what length was higher than the angle of visual field increases it means that the same angle of view, such camera lens needs more compared to standard lens
Large-sized imaging sensor, if in other words it is meant that the imaging sensor of same size, such camera lens is compared to standard lens
The less angle of visual field can only be assumed.Importantly, such camera lens is in imaging, the image analysis power at imaging edge is than in imaging
The image analysis power of the heart is taller, and this is undoubtedly and the visual characteristic of human eye is contrary.
It is different from the above-mentioned two class camera lenses employed in current consumer electronics product, taking the photograph mentioned by the embodiment of the present invention
As head can emulate the visual characteristic of human eye in imaging process, specifically, in embodiments of the present invention, the optics in camera lens 11
Module (i.e. by some optical glasss along the formed module of optical axis arrangement) meets imaging below condition：
Within the default angle of view, it is imaged the absolute value of the ratio with the angle of view for the image height and the difference of constant a
Less than predetermined threshold value；
Outside the described default angle of view, described imaging image height is less than described constant a with the ratio of the angle of view,
And it is more than described predetermined threshold value with the absolute value of the difference of described constant a.
Photographic head described in the embodiment of the present invention imaging as shown in figure 5, near optical axis region, i.e. a default mirror
Within the head angle of visual field, the ratio of imaging image height and the angle of view and the absolute value of the difference of a constant a, less than predetermined threshold value, change sentence
Talk about, in the default angle of view, the ratio of imaging image height and the angle of view almost increases by a year-on-year basis, or can be
The numerical value that specific ray constant a is bigger or specific ray constant a is smaller, that is, close to increasing by a year-on-year basis.And in the region away from optical axis, that is, this is pre-
If the angle of view beyond, imaging image height is drastically compressed, and the ratio of imaging image height and the angle of view is less than this constant a, is in
Non- increase by a year-on-year basis, and the absolute value of the difference of this ratio and constant a is greater than above-mentioned predetermined threshold value so that in this default camera lens
Beyond the angle of visual field, image height is sharp compressed, thus under the imaging sensor of same size, compared to standard lens, energy
Enough realize the broader angle of view.Simultaneously as in the default angle of view, image analysis power is not lost, and pre-
If the angle of view outside, there is loss in image analysis power, this taper body vision having conformed exactly to human eye and shaft-like body vision,
The VR video thus recorded out can meet the actual visual impression of human eye.
Understood based on above description, in embodiments of the present invention, as long as the default angle of view is regarded with human eye cone
The angle of visual field felt matches, then just can be formed on imaging sensor 13 by this camera lens 11 and can distinguish human eye cone
The VR image of vision and shaft-like body vision.Therefore, with reference to the angle of visual field of human eye taper body vision, can be by default camera lens visual field
Angle is set to a certain numerical value in the range of 60～90 degree, for example, the default angle of view is set to 78 degree, then at 78 degree
Within, imaging image height and the angle of view almost wait ratio growth, and beyond 78 degree, are imaged image height and are drastically compressed, by one
Realize on the imaging sensor of sizing approximating the ultra-large vision field angle of the human eye angle of visual field, farthest restore human eye simultaneously
Taper body vision and the sense of reality of shaft-like body vision.
Further, as a preferred embodiment of the present invention, outside the described default angle of view, described one-tenth
Ratio as image height and the angle of view can increase with the increase of the angle of view, so, the closer to photographic head
Imaging edge, can accommodate into more scenery the drastically compression although due to being imaged image height, influence whether to be imaged edge
Image analysis power, exactly because but human eye to imaging edge image analysis power insensitive, therefore this imaging characteristic can't
Produce actual vision loss.

Height, wherein, what curve 61 represented is the imaging characteristic of standard lens it can be seen that in standard lens, being imaged image height and half
The ratio of the angle of view be always identical；What curve 62 represented is fish-eye imaging characteristic it can be seen that in flake mirror
In head, the growth of lens imaging image height is higher than the growth of the angle of visual field；What curve 63 represented is provided in an embodiment of the present invention taking the photograph
As the imaging characteristic of head is it can be seen that when the half of the angle of view is within 40 degree, imaging image height is regarded with the camera lens of half
The ratio of rink corner is almost identical, and outside 40 degree, within the ratio of imaging image height and the angle of view of half is more than 40 degree
Ratio, thus imaging edge accommodate into more scenery.Exemplarily, the curve 63 in Fig. 6 can meet function representation Y
=f*sin θ, wherein, Y is imaging image height, and θ is the angle of view of half, and f is focal length.
