Sensor is absorbed, and by Bayer array sensor collection colour information, half-tone information is gathered by approximately mating plate sensor, finally will
The picture of two sensors is superimposed to image processing system, realizes the effect of enhancing image quality.Collected due to two sensors
Information by same single pick-up lens collection come, be not in photo visual angle difference problem.
Brief description of the drawings
Fig. 1 is the single-lens module imaging arrangement figure one of the utility model；
Fig. 2 is the single-lens module imaging arrangement figure two of the utility model.
Embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description, this
Utility model proposes a kind of embodiment of single-lens module imaging arrangement, and shown in reference picture 1- Fig. 2, including what is set gradually singly take the photograph
As camera lens 1, the spectroscope of incident ray polarization beam splitting, imaging sensor 3 and image processing system 4, the imaging can be sensed
Device 3 includes Bayer array sensor 31 and sensor free of light filter 32, and spectroscopical emergent ray includes Ray Of Light
With the second beam light, the beam ray position of the Bayer array sensor 31 and the Ray Of Light/second is correspondingly arranged, described
The position correspondence of the beam light of sensor 32 and second/Ray Of Light free of light filter is set, the Bayer array sensor 31, nothing
Optical filter sensor 32 is connected by a photoelectric conversion module with described image processing system 4.
A kind of single-lens shaping modular structure is proposed in the present embodiment.During specific setting, including the single shooting set gradually
Camera lens 1, spectroscope, imaging sensor 3 and image processing system 4, it will can be passed through by the effect of the spectroscope 2 in the present embodiment
The incident ray polarization beam splitting of spectroscope 2, make the light beam splitting of injection.
Specifically, make incidence by inserting spectroscope between single pick-up lens 1 and imaging sensor 3 in the present embodiment
Light is divided into two-beam line when projecting.It is irradiated on Bayer array sensor 31, is visitd after wherein a branch of mirror reflection that is split
Ear sensor array 31 absorbs, and Bayer array sensor 31 gathers colour information, and Ray Of Light is directly transmitted through spectroscope in addition
Received by sensor 32 free of light filter, gather gray value information, then by image processing system 4 by the He of Bayer array sensor 31
Two digital pictures superposition generation high resolution image of sensor 32 free of light filter, reaches enhancing image quality effect, so as to shoot
Ignore the high sharpness image of angle error.In set location, Bayer array sensor 31 can be corresponding with the first beam ray position
Set, can also be correspondingly arranged with the second beam ray position, can also be with Ray Of Light when approximately mating plate sensor 32 is set
Position correspondence is set or the second beam ray position is correspondingly arranged, and two sensing stations can realize exchange, as long as it can be positive
Light information is gathered, its particular location is not limited at this.
Specifically, the Ray Of Light in the present embodiment can be reflection light or transmitted ray, the second beam light also may be used
Think transmitted ray or reflection light.
31 each pixel of Bayer array sensor in the present embodiment can only gather RGB one of which colors.In image
Processing stage is by carrying out inverse operation reduction shooting object inherent color to every four rgb pixels point.Approximately mating plate sensor 32
Using the black and white sensor without optical filter, each pixel reflection gray value is the light intensity received.Therefore energy
More scenery detailed information are enough collected, improve acutance.Simultaneously because the imaging arrangement in the present embodiment use for list
Pick-up lens 1, therefore Bayer array sensor 31 and the image that is approximately received on mating plate sensor 32 are just the same, do not regard
Angular difference, effectively solves the existing shooting discrepant problem of photo of twin-lens module imaging arrangement of the prior art.
It is as spectroscopical a kind of embodiment in the present embodiment：The spectroscope is the half-reflecting half mirror being obliquely installed
2.Reflection ray angle depends on spectroscope angle of inclination, and spectroscope does not change transmitted ray angle.Concrete structure is：Spectroscope
Including level crossing and the part reflective semitransparent film being arranged on the level crossing, it is preferred that half-reflection and half-transmission membrane material is APF films.Half is anti-
Pellicle can be formed by plating to set on level crossing, also can be by being bonded one layer of part reflective semitransparent film directly on level crossing come real
It is existing.It is of course also possible to use other set-up modes, are not particularly limited herein.
Further, there is angle of inclination, the angle of inclination is 30-60 degree between the half-reflecting half mirror 2 and horizontal plane.
Preferably, angle of inclination is 45 degree between the half-reflecting half mirror 2 and horizontal plane in the present embodiment, be can be achieved to inciding half-reflection and half-transmission
The light of mirror 2 is divided equally, and makes to incide Bayer array sensor 31 or nothing by a reflection light part for half-reflecting half mirror 2
On optical filter sensor 32, another part is then directly transmitted on sensor 32 or Bayer array sensor 31 free of light filter.
It is as another spectroscopical embodiment in the present embodiment：The spectroscope is polarization splitting prism 5.
It can be divided into the different polarisation of two-way polarization state after the picture signal of camera lens module is by polarization splitting prism 5
Beam.Wherein light beam keeps original direction of propagation to be projected in Bayer array sensor 31 or approximately on mating plate sensor 32.Separately
Bayer array sensor 31 is totally reflected to all the way or approximately on mating plate sensor 32.It is high that generation is superimposed by graphic system again
Image quality image.So as to shoot the high sharpness image for ignoring angle error.Polarization splitting prism 5 in the present embodiment can be centre
It is provided with the polarization splitting prism of Canadian resin or the polarization splitting prism of intermediate coated film.It is of course also possible to it is other structures
Polarization splitting prism, be not particularly limited herein.
Further, forward direction receives the first beam to the Bayer array sensor 31 respectively with the approximately mating plate sensor 32
Light or the second beam light.
Further, the permeable wavelength value of the spectroscope is 380-760nm.380-760nm is the wavelength of visible ray
