The utility model relates to a support display of PAL and NTSC form with enlarging function simple structure, the integrated level is high, and is easy and simple to handle, and the reliability is high.
Description
Technical field
The utility model relates to field of video monitoring, is specifically related to a kind ofly have the support PAL of enlarging function and the display of NTSC form.
Background technology
Along with popularizing of CCD camera, increasing field all employ video monitoring system.At present, in field of video monitoring, display used is exactly directly by the Signal aspects of camera over the display, be similar to television for play TV signal the same, if just observing some by display, to change obvious signal not bad, the lamp on such as picture becomes green from redness, if but need by display observe some be not easy the change found out time, object in such as picture there occurs some thin tail sheep, and the method for the direct Output Display Unit of this camera is just unworkable.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model proposes and a kind ofly have the support PAL of enlarging function and the display of NTSC form, structure is simple, and easy and simple to handle, reliability is high.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of have the support PAL of enlarging function and the display of NTSC form, comprise: image capture module, ADC module, control module, microprocessor module and display apparatus module, described image capture module exports CVBS signal and is bi-directionally connected to described ADC module, described ADC module, control module and described display apparatus module and described microprocessor module.
This display is made up of 5 modules, is image capture module respectively, ADC module, control module, microprocessor module and display apparatus module.Wherein image capture module is an interface female seat, be used for connecting the CVBS signal of video that will be exaggerated, this CVBS signal may be produced by a camera, or a player playing content inside storage medium produces, be similar to DVD, CVBS signal comprises PAL and NTSC two kinds coding standard, this display can be supported, the CVBS signal of coming in from image capture module can enter ADC module, analog CVBS signal is converted into the discernible digital video signal of processor by ADC module, digital video signal is sent to microprocessor module again, microprocessor has two buttons to be attached thereto, these two buttons are for user operation, the function button being video amplifier respectively and reduce.Digital video signal outputs on display and shows by microprocessor in real time.If the button that user presses video amplifier or reduces, processor can zoom in or out process accordingly to ADC module digital video signal out, then output on display and show, before display, picture is all for initial point zooms in or out with the point of display center.
Mitigation and amplification has certain progression, press the number of times that corresponding button is certain, video council zooms in or out certain progression in real time, the quantity of progression can according to actual conditions and customization, and only just can reduce after video amplifier at least one-level, this is just similar on television set and regulates volume the same.
Workflow of the present utility model is as follows:
After this display powers on, display apparatus module can show the simulated image in image capture module, if no signal input in image capture module, then display apparatus module can show a slice green, when there being signal to input in image capture module, CVBS signal will enter ADC module, CVBS signal is changed into digital signal by ADC module, the digital level pin that digital signal is connected with microprocessor module by ADC module enters microprocessor module, this digital signal is become LVDS signal by various algorithm and delivers on display panel module and show by microprocessor module again, whole process is all real-time Transmission, when the signal of image capture module collection changes, just real-time reflecting on display apparatus module, meanwhile, microprocessor module is also just in the reaction of real-time inspection and control module, when the button in control module is pressed, the pin that CPU is connected with button can detect the instruction of pressing, thus the instruction that carries out image zooms in or out.
The utility model structure is simple, cost is low, it is high to configure, integrated level is high, simple to operate, reliability is high, is applicable to the video monitoring of industry, building site, the fields such as the video monitoring of road traffic.
On the basis of technique scheme, also can do following improvement:
As preferred scheme, ADC module have employed chip TVP5150.
Adopt above-mentioned preferred scheme, the structure that CVBS signal is converted to digital video signal is simple, and cost is lower, good stability, and reliability is high.
