New description: [New technical field] This creation provides a light source control device for surveillance cameras, which aims to provide a kind of illumination power of the light source according to the condition of the surveillance camera (image or light source). Light source control device for bright and clear shooting effects. '[Prior technology] • ' Press, the traditional traditional surveillance camera system is installed in the general store, building or community entrances and exits, passages, perspectives can not be monitored and people are invisible, and can be recorded at any time by surveillance cameras. The situation can be used for future investigations, deposits, etc., and can be used to monitor the camera to prevent deterrence. At present, most of the surveillance cameras on the market that have infrared night vision functions are provided with a light-emitting control circuit device around the camera. With the infrared diodes arranged on the camera, when the surrounding environment is dim, Φ will The light source of the infrared light is automatically emitted, so as to provide the camera as a nighttime illumination, so that the camera has the function of night vision; as for the conventional illumination control circuit device, the operation mode mainly uses the photoresistor to sense the surrounding environment of the camera. The darkness, when the surrounding environment is dim to a certain extent - the photoresistor will drive the infrared diode to emit light, and emit a red light source to provide a camera for night illumination. However, conventionally, there is a surveillance camera with infrared night vision function, '' although the illumination control circuit device can provide the camera as a nighttime illumination, the distance of the light emitted by each infrared diode is fixed, so that 3 M364223 When the camera shooting distance is far and near, the shooting effect is not good, f is that when the t camera is far away, the shooting image will be darker, and when the shooting distance is overexposed, the image will be too bright to achieve bright and clear shooting. effect. ^... [New Content] The purpose of the creation is to provide a light source control split that can adjust the luminous power of the light source according to the condition of the monitor (shirt or light source) to achieve a bright and clear shooting effect. For the above purposes of the creation of the present invention, the light source of the creation=the surveillance camera is used to control the light source, and the light source control device is at least: two: a signal generating component, a control component and a light source processing component, a second light and a camera Connecting, the situation generates a sensing signal, and the sensing if f control component 'the control component generates an empty signal according to the sensing signal' is received by the light source processing component, and the light source is adjusted accordingly The power size 'allows the light source to adjust the illumination of the light source according to the condition of the shirt or the light source, for example, it is necessary to shoot a long distance (image or light source), and the light source power of the light source can be increased immediately. Improve the shooting effect. , familiar with the person skilled in the art to understand the purpose, characteristics and merits of this creation, such as by the following specific examples 'and with the attached drawings, detailed description of the way to apply] The structure of the creation, and the operation mode of the whole M364223, are described as follows: The light source control of the camera is installed on the monitor to control the light source, as shown in the first figure. The light source device 10 includes at least: a signal generating component U', the signal generating component u is connected to the line of the monitoring camera, and generates a sensing signal according to the condition of the monitoring camera (image or light source), and The sensing signal is transmitted to the control component 12, a control component 12, and the control component 12 receives the control signal by the light source processing component 13 according to the sensing signal, and a light source processing component 13, The power level of the light source can be adjusted according to the control signal, so that the light source can adjust the light source power of the light source according to the condition of the camera (image or light source). When the need to take a greater distance (or a source video) where dark, light can immediately increase the power of the light emitting, and to enhance the shooting. ^ η according to; as shown in the second figure, when there is a sensed object entering the sensing area, _ 2 唬 produces 7G 11 sensing, and according to the sensing (image or light source) ί month situation The test signal, for example, when the detected object is photographed at a long distance (image or light source) is dark, the light source power of the light source can be increased immediately; otherwise, when the object to be sensed is photographed at a close distance (image or It is a light source. - When the situation is bright, the illumination power of the light source can be immediately reduced, and then the sensing signal is sent to the control element 12. After receiving the sensing signal, the control component 12 generates a control signal according to the sensing signal, and sends the control signal to the light source processing component 13 to adjust the power of the light source according to the control signal by a light source processing component 13 to best value. 5 M364223 "Where, the remote light source processing component 13 can be adjusted by the voltage adjustment circuit 电线 is the wire adjustment circuit, and the power of the light source is adjusted according to the control signal so that the surveillance camera shoots a distant light source." The test signal is controlled by the control element 12It === source processing element 13 to provide different light source power by the power of a light source processing component = : ~ to achieve:: various photography (image or light source) , to provide the best light source power ', the shooting effect is improved. As shown in the third figure, the inside of the camera body, I - / in the empty part 12 can be combined with the surveillance camera can be :::::: ;心二=== When the fruit is different, =;::== machine_distance is far and near difference is too bright and can not be too close, it will produce overexposure, make the shadow point, and provide a better creation, method The lack of bright and clear shooting results in the original = this real =: detailed ^ Wai. That is to say, according to the creation of this application, the scope of this creation is still within the scope of the patent of the creation of the four changes and repairs Dance, etc., all [simplified illustration]; The structure of the device is shown in Fig. ―Day one picture, which is the light source control device and the second picture of the figure in the sword. It is the other structure diagram of the t-light source control device.
