Abstract
The utility model relates to a camera device with a polarized lens between a lens and an optical coupler. The polarized lens is mounted between the optical lens and the optical coupler CCD (charge coupled device) and particularly mounted in a frame controlled by a switching circuit. Polarization process to images behind the optical lens is realized by the aid of the polarized lens, the images after polarization process enter the optical coupler CCD to be processed further, start using of the polarized lens is controlled by an embedded electric control transfer strip, the switching circuit controls whether the polarized lens is used for shooting or not, so that the polarized lens is suitable to be controlled remotely and has use value to a remote monitoring camera. Furthermore, optical lenses in different specification can be selected flexibly to achieve polarized light effect when the camera is in shooting, so that convenience in use is increased. In addition, the camera device has the advantages of reasonable and simple structure, convenience and flexibility in operation and fine effect, and is applied to remote monitoring places such as expressways.
Description
Technical field
The utility model belongs to the photoelectricity technical field, relates to the camera head that is provided with polarized lenses between camera lens and the pale pinkish purple device of light that a kind of optical lens that can select all size flexibly for use obtains the polarized light effect.
Background technology
CCD is that the English of the pale pinkish purple device of light is write a Chinese character in simplified form.
Many polarized lights are harmful in photography.The reflected light of glass surface is taken less than the thing inside the showcase us, and the reflected light of the water surface is taken less than the fish in the water us, and the reflected light on leaf surface makes leaf become white, or the like.If eliminated these polarized lights, many monitoring images can seem, and color is more saturated, and picture is more clear.
Filter that can the filtering polarized light is called polarized lenses.Traditionally, the polarized lenses sheet is installed to the front end of camera lens, carefully rotate polarized lenses, make harmful dazzle reduce to minimum even disappear, so just can shoot has not had the photo of dazzle.If use different camera lenses will change the polarized lenses sheet of different size, in the TV monitoring and controlling field, it is very frequent changing camera lens, will prepare a variety of polarized lenses like this.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of optical lens of all size of selecting for use flexibly to obtain the polarized light effect, has the camera head that is provided with polarized lenses between camera lens and the pale pinkish purple device of light of simple, flexible to operation, the good advantage of result of use rational in infrastructure.
The technical method that its technical matters that solves the utility model adopts is: a kind of camera head that is provided with polarized lenses between camera lens and the pale pinkish purple device of light, between optical lens and the pale pinkish purple device CCD of light polarized lenses is housed, this polarized lenses is contained in the framework by commutation circuit control.
The crossbearer of described framework both sides is contained in the chute of transfer strip both sides.
Both sides at described transfer strip are provided with bolt hole, and transfer strip is fixed by bolts on the shooting casing between optical lens and the pale pinkish purple device CCD of light by bolt hole.
The cover plate of transfer strip is provided with a through hole that matches with polarized lenses.
The beneficial effects of the utility model are: the image after utilizing polarized lenses to optical lens carries out polarisation to be handled, and the image after polarisation is handled enters the pale pinkish purple device CCD of light again and handles; Adopt the control of built-in electric control transfer strip whether to enable polarized lenses, whether use polarized lenses to take by the commutation circuit Long-distance Control, so just be fit to long distance control polarized lenses, for long range surveillance video camera use value is arranged, can select for use the optical lens of all size to obtain the polarized light effect during shooting flexibly, increase the convenience of using, had simple, flexible to operation, advantage that result of use is good rational in infrastructure, be applied to the isometric remote inspection occasion of highway.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of transfer strip described in the utility model.
Among the figure: 1-optical lens, the pale pinkish purple device of 2-light, 3-transfer strip, 4-framework, 5-polarized lenses, 6-through hole, 7-chute, 8-bolt hole, 9-cover plate, 10-video camera.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1 and Fig. 2, a kind of camera head that between camera lens and the pale pinkish purple device of light, is provided with polarized lenses, between optical lens 1 and the pale pinkish purple device 2 of light, polarized lenses 5 is housed, utilize image behind 5 pairs of optical lens 1 of polarized lenses to carry out polarisation and handle, the image after polarisation is handled enters the pale pinkish purple device 2 of light again and handles.Described polarized lenses 5 is contained in the framework 4 that is made by plastics and ferrous material that carries out Long-distance Control by commutation circuit, the crossbearer of these framework 4 both sides is contained in the chute 7 of transfer strip 3 both sides, framework 4 horizontally slips by being controlled in the chute 7 of commutation circuit, realize the switching of polarized lenses 5, whether use polarized lenses 5 to take by the commutation circuit Long-distance Control, can control polarized lenses 5 at a distance, be applied to comprise the long-range of highway apart from monitoring occasion; This polarized lenses 5 is fit to the optical lens 1 supporting use with any specification, polarized lenses 5 is not changed by optical lens 1 when using influence.The cover plate 9 of transfer strip 3 is provided with a through hole 6 that matches with polarized lenses 5 simultaneously; Be provided with bolt hole 8 in the both sides of described transfer strip 3, transfer strip 3 is fixed by bolts on video camera 10 shells between optical lens 1 and the pale pinkish purple device 2 of light by bolt hole 8.
The utility model is equipped with polarized lenses between optical lens and the pale pinkish purple device CCD of light, the image after utilizing polarized lenses to optical lens carries out polarisation to be processed, and the image after polarisation is processed enters the pale pinkish purple device CCD of light again and processes; Adopt the control of built-in electric control transfer strip whether to enable polarized lenses, whether use polarized lenses to take by the commutation circuit Long-distance Control, so just be fit to the long-distance control polarized lenses, for long range surveillance video camera use value is arranged, can select flexibly the optical lens of all size to obtain the polarised light effect during shooting, increase the convenience of using, had simple, flexible to operation, advantage that result of use is good rational in infrastructure.
