Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Below in conjunction with drawings and the embodiments, the present invention is described in further detail.
Referring to Fig. 1-2, the camera module 10 of first embodiment of the invention includes lens barrel 11, the first eyeglass 12, the second eyeglass 13, brake sack 14, substrate 16, and CIS 18.
First eyeglass 12, the second eyeglass 13 and brake sack 14 be housed in lens barrel 11, and brake sack 14 is between the first eyeglass 12 and the second eyeglass 13.Lens barrel 11, the first eyeglass 12, the second eyeglass 13 and brake sack 14 collectively constitute camera lens 15.Camera lens has optical axis 152.
Substrate 16 has relative first surface 161 and second surface 162, is directly connected to the first inclined-plane 163 of first surface 161 and second surface 162, and second surface 162 offers a groove 164, and the through hole 165 of communication groove 164.First inclined-plane 163 tilts towards image side relative to optical axis 152, and around through hole 165.The first surface 161 of substrate 16 can be pasted onto the lower surface of lens barrel 11 by modes such as glue.In the present embodiment, the cross section of through hole 165 is rectangle.In the present embodiment, substrate 16 is ceramic substrate.
CIS 18 is fixed in groove 164 by modes such as glue, and effective photosensitive area 182 of CIS 18 is positioned at the through hole 165 of substrate 16.Effectively photosensitive area 182 has a photosurface 181.Vertical dimension between first surface 161 and the photosurface 181 of substrate 16 is D.
Being appreciated that in other embodiments, the first inclined-plane 163 can also be towards image side.
Owing to effective photosensitive area 182 is positioned at this through hole 165, and major part light cannot arrive effective photosensitive area 182 after the first inclined-plane 163 reflection, thus decreases the reflection light stricture of vagina in the image of imaging.
Preferably, the first inclined-plane 163 is more than 0.27D/8000 along the width W of this optical axis 152 orthographic projection, so can reduce the reflection light stricture of vagina in the image of imaging further.
Fig. 3 is the camera module 20 of second embodiment of the invention, and camera module 20 is with the difference of the camera module 10 of the first embodiment: be provided with multiple stairstepping projection 167 on the first inclined-plane 163.In the present embodiment, the height H of every single order is consistent, and H is more than D/1000.In other embodiments, the height H on each rank can also be different, but, the height H of every single order is all greater than D/1000.By being provided with multiple stairstepping projection 167 on the first inclined-plane 163, the light arriving effective photosensitive area after the first inclined-plane 163 reflection can be reduced further.
Fig. 4 is the camera module 30 of third embodiment of the invention, camera module 30 is with the difference of the camera module 10 of the first embodiment: substrate 16 farther includes the second inclined-plane 166, this second inclined-plane 166 tilts relative to this optical axis 152, and this second inclined-plane 166 is around this through hole 165.This first inclined-plane 163 is connected with this first surface 161, and towards thing side.This second inclined-plane 166 is connected between this first inclined-plane 163 and this second surface 162, and towards image side.
It is appreciated that in other embodiments, the first inclined-plane 163 and/or the second inclined-plane 166 can also arrange multiple stairstepping projection 167 as shown in Figure 3.
In the camera module that the present invention provides, owing to the effective photosensitive district of CIS is positioned at this through hole, and substrate has around this first inclined-plane of this through hole, major part light cannot arrive effective photosensitive area of this CIS after the first slant reflection, thus after decreasing the reflection of via through holes inwall, be projected to the light of described effective photosensitive area, and then decrease the reflection light stricture of vagina in the image of imaging.
It addition, those skilled in the art can also do other change, certainly, these changes done according to present invention spirit in spirit of the present invention, within all should being included in scope of the present invention.
