Abstract
The utility model relates to a monitoring system capable of regulating the illuminating brightness, which is characterized by comprising a camera and a brightness regulating loop, wherein an image processor inside the camera is connected to the brightness regulating loop by a line; the brightness regulating loop comprises a signal conversion circuit, a control circuit, an LED driving circuit and an LED lamp set which are electrically connected mutually; and the signal conversion circuit is connected to the image processor inside the camera by a line. The monitoring system retrieves and converts to generate a brightness level signal related to the brightness of the current outside environment from AGC, VIDEO, IRIS or PWM output signals of the image processor inside the camera, correspondingly generates a brightness control signal according to the size of the signal level and further can immediately provide enough illuminating brightness which is required when the camera is used to take a photograph according to the light brightness in the outside environment without judging the light brightness of the field environment by an external sensitive element device so as to not only effectively reduce manufacturing cost of the monitoring system, but also provide more accurate judgement on the brightness of the field environment.
Description
Technical field
The utility model relates to a kind of surveillance that brightness of illumination is adjusted of carrying out, and refers to a kind of surveillance of carrying out the brightness of illumination adjustment according to the bright and dark light that environment is set especially.
Background technology
Being generally positioned at the video camera of the surveillance in building, elevator or parking lot, mainly is a side that is installed on corner or ceiling; Therefore; video camera mostly also has a segment distance apart from shooting with video-corder the position, place; so in the corner or the brightness of illumination of ceiling and the brightness of illumination that will shoot with video-corder the position, place inconsistent or luminance difference is significantly arranged through regular meeting's generation brightness; and then cause the image frame luminance shortage of being shot with video-corder and can't know identification, more even image fog, unclear situation arranged.
The utility model content
The purpose of this utility model provides a kind of surveillance that brightness of illumination is adjusted of carrying out, mainly be by capturing, change out the accurate position of relevant brightness with external environment brightness at present signal in AGC, VIDEO, IRIS or the PWM output signal with the image processor of video camera inside, and come the corresponding brilliance control signal that produces, and then can be immediately provide the enough brightness of illumination of this video camera when the photography according to the light luminance of external environment according to the size of its signal reference position.
The purpose of this utility model is achieved in that a kind of surveillance that brightness of illumination is adjusted of carrying out, and comprising: the loop is adjusted in video camera and brightness; Wherein, the image processor of this video camera inside then is to be linked to this brightness with circuit to adjust the loop.The loop is adjusted in this brightness, then comprises: signal change-over circuit, control circuit, led drive circuit and LED lamp group, and then be mutual electrically connect each other; Wherein, this signal change-over circuit then is the image processor that is linked to this video camera inside with circuit.
The utility model has the advantages that: can be immediately provide this video camera enough brightness of illumination when the photography according to the light luminance of external environment, and need not judge the light luminance of site environment again by external photo-sensitive cell device, not only can effectively reduce the manufacturing cost of this surveillance, and differentiate by the image signal that this video camera is taken in, the judgement of the size of site environment brightness more accurately then can be provided.

Embodiment
Below sincerely with a specific embodiment, and assistant elaborates with graphic, so that the juror can have further and understand for technical characterictic of the present utility model.
See also Fig. 1～Fig. 2, the utility model relates to a kind of surveillance 1 that brightness of illumination is adjusted of carrying out, and comprising: video camera 2 is adjusted the loop with brightness; Wherein, the image processor 21 of these video camera 2 inside is to be linked to this brightness with circuit to adjust the loop.This brightness is adjusted the loop and is comprised: signal change-over circuit 31, control circuit 32, led drive circuit 33 and LED lamp group 34, and then be mutual electrically connect each other; Wherein, this signal change-over circuit 31 then is the image processor 21 that is linked to these video camera 2 inside with circuit.And the AGC of image processor 21, VIDEO, IRIS or PWM output signal more can link by circuit and export this signal change-over circuit 31 to.
This video camera 2 then is that the light source with external environment converts electrical signal to, and by the image processor 21 of inside electrical signal is carried out image processing, and corresponding various image signal and the controlling signal of producing; This signal change-over circuit 31 then is that arbitrary or its combination in any with AGC, VIDEO, IRIS and the PWM output signal of the image processor 21 of these video camera 2 inside converts the accurate position of brightness signal to; This control circuit 32 then is to convert the accurate signal of the brightness of this signal change-over circuit 31 to the brilliance control signal; This led drive circuit 33 then be that brilliance control signal with this control circuit 32 converts LED to and drives signal, and the size of utilizing LED to drive signal comes corresponding control ring to be located at the brightness of illumination of this LED lamp group 34 of this video camera 2.
This surveillance 1, mainly be by AGC with the image processor 21 of these video camera 2 inside, VIDEO, capture in IRIS or the PWM output signal, change out the brightness accurate position signal relevant with external environment brightness at present, and according to the next corresponding brilliance control signal that produces of the size of its signal reference position, and then can be immediately provide the enough brightness of illumination of this video camera 2 when the photography according to the light luminance of external environment, and need not judge the light luminance of site environment again by external photo-sensitive cell device, not only can effectively reduce the manufacturing cost of this surveillance 1, and differentiate by the image signal that this video camera 2 is taken in, the judgement of the size of site environment brightness more accurately then can be provided.
