Abstract
The invention relates to a lens module for surveillance camera shooting. The lens module comprises a connector as well as a camera shooting module PCB (Printed circuit board), an image sensor, a lens bracket and a lens which are connected in sequence in the connector from bottom to top, wherein a dual-filter switcher is arranged between the lens and the lens bracket, and the positive and negative electrodes of the dual-filter switcher are connected with a PAD on the camera shooting module PCB so as to provide a power supply and switch instructions. The lens module has the beneficial effects that the lens module can be used day and night, and the image is not distorted; infrared light can be filtered to ensure the color of images is softer and is consistent with vision colors of human eyes; and simplicity and convenience in assembly are achieved and the space is saved.
Description
Technical field
The present invention relates to the monitor camera device technical field, especially relate to a kind of camera lens module of monitoring camera.
Background technology
Along with socioeconomic fast development; Social public security also receives the many concerns of People more and more; The security protection industry is very swift and violent as a novel industry development speed, and the development of intelligent security and guard technology has obtained remarkable achievement, from big to the whole video monitoring system of safeguarding national security to the neighbours living safety and protection system; Even in the onboard system that uses of individual or the like in the monitoring camera product; All in model change fast, gone on identical road, no matter be that function or effect are all significantly unusual, for the security protection industry has been made significant contribution.According to investigations, recent security protection market has reached excelsior link for the functional of product, because all kinds of security products are a feast for the eyes on the market; Function and the product quality state that all tended to be steady still, wants on properties of product even better; Just must sternly work hard and add in each link; Comprise external form, picture quality, functional or the like.Wherein, image has directly shown the quality of properties of product, has also shown the quality of this product, and the day and night mega pixel then is widely used in the video monitoring because of the clear quilt of hidden and shooting picture that satisfies under the environment at night in a large number.
Nature exists the light of various wavelength, and between the wave-length coverage 320nm-760nm of human eye identification light, the light human eye that surpasses 320nm-760nm just can't be seen, such as infrared light, ultraviolet ray etc.The imaging components and parts CCD of video camera or COMS can see the light of most wavelength, because the participation of various light, there are deviation in color that video camera restored and finding of naked eye on color.Current programme is before CCD, to paste a single or multiple lift (letting visible light and infrared light pass through simultaneously) 760nm or the bimodal filter of 850nm.Because infrared and other veiling glares get into CCD and can disturb color rendition, become greyish white like green plants by day, red clothes is thin out or the like (have solaria external environment especially obvious); Because the filtration of bimodal filter makes CCD can not make full use of all light, noise and the low performance of shining thereof are difficult to satisfactory at night.
Therefore, the appearance of the camera lens module of a kind of day and night, distortionless monitoring camera is necessary.
Summary of the invention
The present invention is to provide the camera lens module of a kind of day and night, distortionless monitoring camera for solving the problems of the technologies described above.
The technical problem that the present invention solved adopts following technical scheme to realize:
A kind of camera lens module of monitoring camera; Comprise connector; In said connector, be connected with shooting module pcb board, imageing sensor, lens bracket, camera lens from bottom to top in turn, wherein, be provided with two filter switchs at said camera lens and said lens bracket spare; The positive and negative electrode of said pair of filter switch is connected with PAD on the said shooting module pcb board, so that power supply and switching command to be provided.
Further, be provided with epoxy resin in the junction of said lens bracket and said imageing sensor.
Further, said pair of filter switch comprised color screen and Penetrating Fog filter disc, and said Penetrating Fog filter disc is by the near-infrared filter disc of, back all-pass before the wavelength 760nm.
The beneficial effect that the present invention has is: (1) day and night, and image is undistorted;
(2) can filtering infrared light make picture color softer, it be consistent to reach the human eyes visual color;
(3) assembling is easy, saves the space.
Description of drawings
Fig. 1 is the present invention: a kind of structural representation of camera lens module of monitoring camera;
Wherein: 1-connector, 2-shooting module pcb board, 3-imageing sensor, 4-lens bracket, the two filter switchs of 5-, 6-camera lens, 7-PAD, 8-epoxy resin.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with concrete diagram, further set forth the present invention.
With reference to shown in Figure 1; A kind of camera lens module of monitoring camera comprises connector 1, in connector 1, is connected with shooting module pcb board 2, imageing sensor 3, lens bracket 4, two filter switch 5, camera lens 6 from bottom to top in turn; Wherein, Two filter switchs 5 are arranged between camera lens 6 and lens bracket spare 4, and the positive and negative electrode of two filter switchs 5 is connected with PAD7 on the shooting module pcb board 2, so that power supply and switching command to be provided; Two filter switchs 5 have comprised color screen and Penetrating Fog filter disc, and the Penetrating Fog filter disc is by the near-infrared filter disc of, back all-pass before the wavelength 760nm.
Junction at lens bracket 4 and imageing sensor 3 is provided with epoxy resin 8.
Module bulk process of the present invention is: with image sensor 3 pasters on shooting module pcb board 2; Put epoxy resin 8 then around shooting module pcb board 2; Lens bracket 4 is assemblied on the shooting module pcb board 2, again camera lens 6 is assembled on the lens bracket 4, put into lens bracket 4 the insides to two filter switchs 5 at last; Behind the baking-curing, on the shooting module pcb board 2 with lens bracket 4 on the turn of the screw fix and get final product.On shooting module pcb board 2, be designed with PAD7, PAD7 is connected with the both positive and negative polarity of two filter switchs 5, resets through switching self check, through CPU image data, analysis, prevents the phenomenon of switching repeatedly during switching.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
