The remarkable improvement of the invention is that the camera equipment can automatically send an instruction to switch the ray filter according to need, thus the long standing problem that the automatic switching control of the ray filter of the camera equipment can be not realized in the case of nobody on duty can be solved, and high-definition images can be captured by the camera equipment under the all-weather light condition.
Description
Affiliated technical field:
The technology of the present invention field is photography, shooting field, by control to optical filtering, can allow video camera or camera have stronger environmental suitability, capture the more picture or the image of good quality, be specifically related to shooting or camera lens are installed additional the filter glass control device.
Technical background
At present, in photography or shooting field, in order to obtain desirable shooting effect, various optical filterings have been produced, for example polariscope, gray scale mirror, color filter, UV mirror or the like.The mounting means of optical filtering has permanent type to install and two kinds of detachable installations.For the permanent type mounting means, equipment is used under the particular environment, and ambient light changes very little, does not need to switch optical filtering generally speaking; For the application of detachable mounting means, modal is the equipment that is used to carry, and when needing, the suitable shooting effect of optical filtering to obtain wanting is installed.Photography or picture pick-up device for some special uses, for example the traffic road junction is specifically designed to the equipment of the vehicle image of shooting clear, because environment more complicated of living in, and equipment is in the unmanned state in most cases, wants to utilize certain optical filtering, but can only just can reach ideal effect under certain particular environment condition, after ambient light changes, for example day and night change, Changes in weather, optical filtering not only can not improve shooting quality, can have a negative impact to shooting quality on the contrary.Therefore press for a kind of device of convenient switching optical filtering, can be in needs, by people's operated from a distance or send instruction automatically by opertaing device and carry out optical filtering and switch, under round-the-clock various light condition, all can capture HD image to guarantee photography or picture pick-up device.
Summary of the invention
In order to solve the problem that optical filtering switches, the present invention has designed a cover optical filtering switching control.This device be installed in take a picture or camera lens before, change the control line level state or by serial ports to the control circuit transmitting control commands, can reach the purpose of switching optical filtering.
Optical filtering switching control of the present invention comprises photography or picture pick-up device, support, driving circuit, stepper motor, swing arm, arm shaft, optical filtering.The annexation of optical filtering switching control is: the control output end of photography or picture pick-up device is connected with the input end of driving circuit, the output terminal of driving circuit is connected with the input end of stepper motor, the base of stepper motor is fixedlyed connected with support, the central rotating shaft of stepper motor and swing arm engagement are rotationally connected, the central rotating shaft gear driven swing arm of stepper motor is rotated, and the other end of swing arm is installed optical filtering.
Control device constitutes: designed a swing arm that is driven by stepper motor, an end is installed optical filtering in the swing arm, and the other end is the gear that is connected with the step motor drive axle.Stepper motor is driven by driving circuit, and driving circuit can be accepted two kinds of control modes: high/low level control and serial communication port order control.When the driving circuit control line receives different level or different control command, the stepper motor running, then drive swing arm and rotate, swing arm drives optical filtering and turns to and photography or the corresponding position of picture pick-up device camera lens, thereby reaches the purpose of switching optical filtering.
Control principle is the high level and the respectively corresponding two kinds of different optical filtering states of low level of control line, driving circuit detects the state of control line at any time, when the control line level changes, driving circuit is according to previous status, send main story or inversion driving signal to stepper motor, motor rotates, gear driven swing arm tooth bar, swing arm is rotated, and the optical filtering state in the swing arm changes thereupon, when the motor rotational angle reaches the angle of setting, driving circuit stops to send the motor turn signal, the motor stall, swing arm is parked in certain location, and driving circuit is remembered new control line state.
Driving circuit receives the control command of controller, converts control command to motor drive signal, finish the swing arm state--being the optical filtering state---control.The receivable control command of driving circuit has dual mode: mode one: level signal, adopt 1 the tunnel--and promptly corresponding two kinds of optical filtering states; But also multichannel---be corresponding multiple optical filtering state, every many one tunnel control signals, corresponding optical filtering status number is taken advantage of in 2; Mode two: the control of serial port command byte, maximum can allow 256 kinds of optical filtering states.256 kinds of optical filterings of optical filtering switching control, optical filtering are a kind of in polariscope, UV mirror, gray scale mirror, day light microscopic, infrared mirror, the color filter mirror.Or being used in combination more than a kind of optical filtering.
Photography or picture pick-up device: be meant to transmit control signal or the opertaing device of control command, just be used for the equipment or the people of optical filtering switching control.Be generally by taking a picture or video camera itself or by the dedicated control circuit of its driving, its effect is according to the realtime graphic of taking a picture or video camera provides, judge the site environment situation, whether need to switch optical filtering with decision, when needs switch optical filtering, photography or picture pick-up device send steering order: change control line high level/low level state, or from the serial communication port transmitting control commands.
The optical filtering switching control is used to carry out this steering order exactly, realizes a kind of control device of optical filtering change action.
The marked improvement of optical filtering switching control of the present invention is can send instruction automatically by photography or picture pick-up device in needs to carry out the optical filtering switching, solved the photography or the picture pick-up device that exist for a long time and can not realize the problem that optical filtering automaticallyes switch and controls, under round-the-clock light condition, all can capture HD image to guarantee photography or picture pick-up device at the unmanned state.
