Abstract
The utility model belongs to the technical field of cameras, and specifically relates to an automatic light modulation system of a camera. The light modulation system comprises an external light collection unit which samples outside illuminance, an acquisition unit which acquires a real-time status value of the camera, and an analyzing and processing unit which receives, compares, and processes information collected by the external light collection unit and the real-time status value of the camera acquired by the acquisition unit, and the analyzing and processing unit transmits an analysis result to a driving unit which drives a camera light-supplementing light source to work. The automatic light modulation system of the camera can change the output power of the camera light-supplementing light source according to the outside illuminance, thereby achieving the purpose of automatic light modulation, solving the problem that since the light-supplementing light source is always in a full-power state, excessive heat is caused, prolonging the service life of the light source, and ensuring the overall quality of the product.
Description
Technical field
The utility model belongs to the camcorder technology field, is specifically related to a kind of video camera automatic light control system.
Background technology
There is such problem in the supplementary lighting sources of traditional cameras: present video camera is zoomable, can regulate visual range, therefore supplementary lighting sources should consider that closely the light filling scope is wide, consider again remote light filling effect, the power of supplementary lighting sources all is do larger, but such design brings the another one problem, be exactly because supplementary lighting sources power is large, cause the large problem of caloric value, and existing supplementary lighting sources all concentrates in together, the caloric value of its light source will be larger, and supplementary lighting sources substantially all is to be contained in the airtight space, and heat is difficult for coming out, and supplementary lighting sources is exactly to work long hours in the higher environment of temperature like this, will cause greatly shorten the useful life of light source, affect the product overall quality.
The utility model content
For above-mentioned technical problem, the utility model provides a kind of video camera automatic light control system, it can change according to ambient light illumination the power output of video camera supplementary lighting sources, make it reach purpose with an automatic light meter, solved that to be in the heating that the full power state causes excessive always because of supplementary lighting sources, prolong the useful life of light source, guarantee the overall quality of product.
The realization the technical solution of the utility model is as follows:
The video camera automatic light control system, this light adjusting system comprises the outer light collection unit that illuminance is to external world sampled, the acquiring unit that video camera real-time status value is obtained, and the information of externally light collection unit collection, video camera real-time status value that acquiring unit gets access to receives the analysis and processing unit of comparison process, and the result that described analysis and processing unit will be analyzed is transferred to the driver element of actuated camera supplementary lighting sources work.
Adopted such scheme, outer light collection unit gathers the illuminance in the video camera external world, acquiring unit obtains the real-time status value of video camera, the illuminance that the external light collection of analysis and processing unit unit collects is analyzed, and compare with camera status value that acquiring unit gets access to, when the ambient light illumination that collects during greater than set point, analysis and processing unit will be sent the signal that reduces the supplementary lighting sources output current to driver element, reduces the power stage of video camera supplementary lighting sources; And when the ambient light illumination that collects during less than set point, analysis and processing unit will be sent the signal that increases video camera supplementary lighting sources output current to driver element, increase the power output of supplementary lighting sources, thereby realize purpose with an automatic light meter, solved that to be in the heating that the full power state causes excessive always because of supplementary lighting sources, prolong the useful life of light source, guaranteed the overall quality of product.
Description of drawings
Fig. 1 is theory diagram of the present utility model;
Among the figure, 1 is outer light collection unit, and 2 is acquiring unit, and 3 is analysis and processing unit, and 4 is driver element, and 5 is supplementary lighting sources.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Referring to Fig. 1, the video camera automatic light control system, this light adjusting system comprises the outer light collection unit 1 that illuminance is to external world sampled, the acquiring unit 2 that video camera real-time status value is obtained, and the information of externally light collection unit collection, video camera real-time status value that acquiring unit gets access to receives the analysis and processing unit 3 of comparison process, and the result that analysis and processing unit 3 will be analyzed is transferred to the driver element 4 that actuated camera supplementary lighting sources 5 is worked.Wherein, outer light collection unit gathers the illuminance in the video camera external world, acquiring unit obtains the real-time status value of video camera, the illuminance that the external light collection of analysis and processing unit unit collects is analyzed, and compare with camera status value that acquiring unit gets access to, when the ambient light illumination that collects during greater than set point, analysis and processing unit will be sent the signal that reduces the supplementary lighting sources output current to driver element, reduces the power stage of video camera supplementary lighting sources; And when the ambient light illumination that collects during less than set point, analysis and processing unit will be sent the signal that increases video camera supplementary lighting sources output current to driver element, increases the power output of supplementary lighting sources, thereby realizes purpose with an automatic light meter.
Claims (1)
1. video camera automatic light control system, it is characterized in that: this light adjusting system comprises the outer light collection unit that illuminance is to external world sampled, the acquiring unit that video camera real-time status value is obtained, and the information of externally light collection unit collection, video camera real-time status value that acquiring unit gets access to receives the analysis and processing unit of comparison process, and the result that described analysis and processing unit will be analyzed is transferred to the driver element of actuated camera supplementary lighting sources work.
