Abstract
The utility model relates to a makeup flashing control device of LED in synchronous action with the video camera, comprises a light source control processor, a synchronous timer, an LED flasher, a crystal oscillator clock and a video camera. The light source control processor is connected with the synchronous timer and the video camera and the synchronous timer is connected with the LED flasher. The crystal oscillator clock is connected with the synchronous timer. Compared with the prior art, the utility model provides a flashing source which is flicker free and synchronous with the shutter of the video camera. The utility model synchronizes the flashing pulse of the LED light source and the shutter and supplies light source with high-speed flashing, so can reduce the consumption of the electric energy and prolong the LED life by reducing the working temperature of the LED on the prime of ensuring the light. The utility model can also reduce the brightness of the light source while keeping the imaging quality, which avoids that the light glares the eyes, so has an advantage of taking picture unaffectedly.
Description
Technical field
The utility model relates to the video camera light compensating apparatus, relates in particular to the control device of video camera synchronous LED flash light compensation.
Background technology
Under the low-light (level) environment, common camera (non-low-illuminance cameras, non-ultra-low illumination (starlight level) video camera) can not imaging or the very big picture quality of noise of image very poor.
In order to remedy the problem of general camera illumination deficiency under the low-light (level) environment, generally adopt secondary light source to illuminate the zone that video camera is taken.This secondary light source constant luminance incandescent lamp commonly used continues illumination or the constant luminance white light LEDs continues illumination.
Auxiliary light filling light source is indoor or half indoor half outdoor utility is maximum, such as the ATM (automatic teller machine) illumination of bank's Administrative Area, 24 hour self-help banks, the indoor and outdoor corridor of office block, the escalator in building or the like.
Outdoor utility also has, but mostly outdoor utility is security monitoring, the infrared light filling illumination of many employings when night or illumination deficiency.Such as road monitoring, square security monitoring, expressway traffic monitoring or the like.
In above-mentioned many application scenarios of giving an example, the power supply power supply is no problem, and the image that allows to use the low cost high power lighting to guarantee that video camera obtains satisfies application requirements.
But for some application, electric power system can not provide powerful illuminalive power-supply.In this case, generally can select expensive White-light LED illumination scheme for use, throw light on or the like in the shooting under low-light (level) of the shooting illumination under the low-light (level), household video camera such as mobile phone.These lighting systems all are that the constant luminance white light LEDs continues illumination, and the illumination of LED, power supply are controlled simple and reliable, with low cost.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of under the prerequisite that guarantees image quality for the defective that overcomes above-mentioned prior art existence, and the people who is taken does not have the control device of the video camera synchronous LED flash light compensation of lamp from dazzling sensation.
The purpose of this utility model can be achieved through the following technical solutions: the control device of video camera synchronous LED flash light compensation, it is characterized in that, comprise light source control processor, synchro timer, LED flashlamp, crystal oscillator clock, video camera, described light source control processor is connected with synchro timer, video camera respectively, described synchro timer is connected with the LED flashlamp, and described crystal oscillator clock is connected with synchro timer.
Compared with prior art, the utility model provides that do not glimmer and synchronous with camera shutter stroboscopic light sources.Led light source flash pulse and shutter are carried out synchronously, for video camera provides the light source of flash of light at a high speed, at the prerequisite decline low power consumption that guarantees light filling, thus and the life-span of reducing the working temperature prolongation LED of LED in this way.Can also be when the people be made a video recording, under the prerequisite that guarantees image quality, the brightness of sensation light source is lower, and the people who is taken does not have the lamp from dazzling sensation, so the advantage of shooting process performance nature.
Description of drawings
Fig. 1 is the structural representation of the control device of the utility model video camera synchronous LED flash light compensation.
Embodiment
As shown in Figure 1, this Fig. 1 is the structural representation of the control device of the utility model video camera synchronous LED flash light compensation, and its structure comprises light source control processor 1, synchro timer 2, LED flashlamp 3, crystal oscillator clock 4, video camera 5.
Brightness regulation shutter speed according to image, the shutter parameter is sent to video camera 5 and light source control processor 1, light source control processor 1 is tabled look-up according to the shutter parameter and is obtained the phase parameter of control light source, according to phase parameter and shutter parameter synchro timer 2 is set then.
Synchro timer 2 is under the driving of 1.0000MHz crystal oscillator clock 4, and descending synchronously in 2 frequency multiplication field sync signals, phase place and pulsewidth to light pulse are carried out high precision timing, make the flash pulse of LED flashlamp 3 and the shutter synchronization of video camera 5, and its frequency is 4 times of the shutter frequency, does not have flickering with the light source that guarantees LED flashlamp 3.
