Abstract
The utility model belongs to the technical field of cameras, and provides a camera with an automatic light supplementing function, which comprises an ambient light detection sensor, an MCU controller and a light supplementing lamp; the light filling lamp is a plurality of LED lamps, and a plurality of LED lamp equipartitions form the ring-type around the camera, ambient light detection sensor's output links to each other with the MCU controller, and the output of MCU controller links to each other with the driver of LED lamp. The utility model discloses simple structure, convenient to use have ambient light detection function, carry out automatic light filling to the camera, improve the imaging quality.
Description
Technical field
This utility model belongs to camcorder technology field, is specifically related to a kind of video camera with automatic light filling function.
Background technology
Video camera of a great variety, the ultimate principle of its work is just as: optical image signal is changed into telecommunications
Number, in order to store or transmit.When we shoot an object, on this object, the light of reflection is collected by camera lens,
Make it focus on the sensitive surface of picture pick-up device (target surface of such as pickup tube), then by picture pick-up device, light be changed into electric energy,
I.e. obtain " video signal ".The image quality of photographic head and the brightness of surrounding are closely bound up, at some than dark ground
Side can cause camera imaging to obscure, and noise is bigger, and this leverages user's impression and experiences.
Summary of the invention
The purpose of this utility model is contemplated to overcome above-mentioned weak point of the prior art, and the one provided has
The video camera of automatic light filling function, its simple in construction, easy to use, there is ambient light detection function, photographic head is carried out automatically
Light filling, improves image quality.
The present invention solves that its technical problem the technical scheme is that a kind of video camera with automatic light filling function,
Including environment light detecting sensors, MCU controller, light compensating lamp；Described light compensating lamp is multiple LED, and multiple LED are uniform
Being formed ring-type around photographic head, the outfan of described environment light detecting sensors is connected with MCU controller, and MCU is controlled
The outfan of device processed is connected with the driver of LED.
In technique scheme, described ambient light detection sensor model number is ISL29023.
In technique scheme, described MCU controller model is RK3288.
In technique scheme, described LED driver model is SY7201ABC.
This utility model has the video camera of automatic light filling function, can effectively detect ambient light, in the feelings that ambient light is dark
Under condition, open light compensating lamp, regulate brightness, improve camera imaging quality.
Accompanying drawing explanation
Fig. 1 is the circuit connection diagram of this utility model embodiment.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, the present embodiment provides a kind of video camera with automatic light filling function, including ambient light detection sensing
Device, MCU controller, light compensating lamp；Described light compensating lamp is 4 ~ 10 LED, LED be distributed on around photographic head formed ring-type,
The outfan of described environment light detecting sensors is connected with MCU controller, the outfan of MCU controller and LED
Driver be connected.
In the above-described embodiments, the ambient light detection sensor model number of employing is ISL29023, MCU controller model
For RK3288, LED driver model is SY7201ABC, it is possible to select other model according to actual needs.
Operation principle of the present utility model is: is arranged on environment light detecting sensors on video camera and detects current environment in real time
Brightness, and by iic bus and MCU communication, when starting photographic head, MCU first reads current environmental light brightness
Value, and compare with default brightness value, when judging that ambient light is partially dark, it is bright that MCU sends light compensating lamp to LED driver
Degree control signal, can control LED driver by the frequency of regulation light compensating lamp brightness control signal and light compensating lamp brightness is adjusted
Whole to suitable brightness value, it is simple to blur-free imaging.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit of the present utility model
Protection domain.
