Embodiment
See also Fig. 1, be a kind of camera lens module 100 that embodiment of the present invention provides, it comprises a lens barrel 101, the first eyeglass 11, the second eyeglass 12, prismatic glasses 13, the 4th eyeglass 14, the 5th eyeglass 15, four anti-dazzling screens 20 and an image sensor 30.
Described lens barrel 101 is cylindric, it comprise a semi-enclosed thing end face 102, one untight as end face 103 and one with described thing end face 102 and the accommodation space 104 that all is connected as end face 103.In the present embodiment, the inside diameter D of described picture end face 103 is 5.3mm.
Described the first eyeglass 11, the second eyeglass 12, prismatic glasses 13, the 4th eyeglass 14 and the 5th eyeglass 15 are contained in the described accommodation space 104, and are arranged in order to the picture end from the thing end along the direction of the optical axis M of described camera lens module 100.Each eyeglass includes an optics section and a non-optical division.Described optics section is used for carrying out optical imagery.Described non-optical division connects around described optics section.During capture, the light that is reflected by the object is to pass through successively described the first eyeglass 11, the second eyeglass 12, prismatic glasses 13, the 4th eyeglass 14 and the 5th eyeglass 15, images on the described image sensor 30.
Described four anti-dazzling screens 20 are made by elastic material and are the hollow circular ring shape, are contained in the described accommodation space 104, and are separately positioned between the non-optical division of adjacent two eyeglasses.
In conjunction with shown in Figure 2, the non-optical division of described the second eyeglass 12 comprises first support division 121, two the second support divisions 122, two connecting portions 123, two the 3rd support divisions 124 and two the 4th support divisions 125.Described the first support division 121 offsets with the inwall of described lens barrel 101, described two the second support divisions 122 lay respectively at thing end surfaces and the picture end surfaces of the second eyeglass 12, offset with described prismatic glasses 13 with described the first eyeglass 11 respectively, and all the optical axis M with described camera lens module 100 is vertical.Described two connecting portions 123 lay respectively at thing end surfaces and the picture end surfaces of the second eyeglass 12, are connected to described the first support division 121 and are connected with corresponding the second support division 122.Described two the 3rd support divisions 124 lay respectively at thing end surfaces and the picture end surfaces of the second eyeglass 12, offset with described prismatic glasses 13 with described the first eyeglass 11 respectively, and all are the acute angle angle with the optical axis M of described camera lens module 100.Described two the 4th support divisions 125 lay respectively at thing end surfaces and the picture end surfaces of the second eyeglass 12, offset with corresponding anti-dazzling screen 20 respectively, and are connected between the 3rd corresponding support division 124 and the corresponding optical surface.The processing that all atomizes on described two the second support divisions 122, described two connecting portions 123 and described the 4th support division 125 is to eliminate the scatter parasitic light of shape of GENERAL TYPE.In other embodiments, the camera lens module of other structures is the corresponding processing that partly atomizes on the second eyeglass of described thing end, can realize such effect.
In conjunction with shown in Figure 3, the processing that atomizes of the position of intersecting as the optics section of end surfaces and non-optical division of described the 4th eyeglass 14.Concrete, the intersection point O that intersects take optics section and the non-optical division of described the
4th eyeglass 14 take R1 as radius, makes a circle as the center of circle, the processing that atomizes of the part between the intersection point that the optics section of described circle and described the
4th eyeglass 14 and non-optical division is crossing, wherein
,
In the present embodiment, R1 is 0.1mm.So, in the time of can alleviating described light source and become 38 ° of angles with the optical axis M of described camera lens module 100, described light source parasitic light of the other falcate of light source in the imaging on described image sensor 30.
In conjunction with shown in Figure 4, on the non-optical division of the thing end surfaces of described the
5th eyeglass 15 near the part of corresponding optics section by the part of pruning, form an inclined-plane 154.Angle between the optical axis M of described inclined-
plane 154 and described camera lens module 100 is θ,
In the present embodiment, θ is 75 °.Described inclined-
plane 154 is D1 with corresponding
anti-dazzling screen 20 near the distance between the end of the optical axis M of described camera lens modules 100 with the intersection point A of corresponding optics section,
,
In the present embodiment, D1 is 0.17mm.The processing that atomizes of described inclined-plane 154.So, in the time of can eliminating described light source and become 34 ° of angles with the optical axis M of described camera lens module 100, described light source parasitic light of falcate in the imaging on described image sensor 30.
In conjunction with shown in Figure 5, on the picture non-optical division of end surfaces of described the 5th eyeglass 15 near corresponding optics section, and with the processing that atomizes of corresponding anti-dazzling screen 20 discontiguous parts, in the time of can eliminating described light source and become 38 ° of angles with the optical axis M of described camera lens module 100, described light source parasitic light of shield shape in the imaging on described image sensor 30.
In other embodiments, the quantity of the eyeglass in the described camera lens module 100 is not limited in the present embodiment, such as the eyeglass that other also can be set between described the second eyeglass 12 and described the 4th eyeglass 14.Also can do corresponding processing with similar other eyeglasses of described the second eyeglass 12, described the 4th eyeglass 14 and described the 5th eyeglass 15 shapes.
Camera lens module of the present invention is processed by doing atomizing in the different piece of each eyeglass, can effectively eliminate described light source parasitic light in the imaging on described image sensor, with the image quality of the described camera lens module of Effective Raise.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
