Abstract

The utility model discloses a kind of multipurpose viewfinder, including RG VF interface, external TALLY interface, rearmounted big TALLY lamp, adjustable TALLY lamp switch.This utility model can be by changing different viewfinder VF cables using the video camera with different brands, as Sony, Panasonic, Hitachi's GVG etc., reduce and repeat because video camera is different to purchase the expense of viewfinder, after the completion of viewfinder configuration, only need viewfinder to connect VF cable can use to video camera VF interface, external TALLY interface can solve no system CCU, and TALLY signal directly controls viewfinder TALLY lamp by cut bank.Saving of purchase cost and satisfaction are without application demand.

Description

A kind of multipurpose viewfinder

Technical field

This utility model is related to a kind of multipurpose viewfinder.

Background technology

Such viewfinder is the recording floor for movie and video programs, and the output of real-time monitoring video camera shoots the weight of signal Want instrument.Working method is：Video camera image recording and sound, real-time input signal (VF bus signals) is to viewfinder simultaneously. Viewfinder simulated television or motion picture screen mode, whether rationally observation photography composition, applies the built-in analysis software of viewfinder simultaneously Assessment audio frequency and video index of correlation.

Viewfinder has following sections to constitute now：Shell, liquid crystal display screen, drive circuit, packing cratess.

The basic profile of existing viewfinder, adopts import viewfinder substantially, video camera must supporting original-pack viewfinder, Other brand video cameras cannot use.The model having various brands that television station studio, program play staff, mobile control room use Video camera, increases TV programme and shoots with video-corder making side's buying expenses.

Content of the invention

Technical problem to be solved in the utility model is to provide a multipurpose viewfinder, can solve different brands and take the photograph Camera viewfinder can not be general problem.

This utility model is achieved through the following technical solutions：Viewfinder RG-VF interface, rearmounted TALLY interface, after Put big TALLY lamp, adjustable TALLY lamp luminance switch.

As preferred technical scheme, described viewfinder RG-VF interface has cambered surface chamfering for circle interface interface surface.

As preferred technical scheme, described rearmounted TALLY interface can be connected as circle interface, can connect switching Platform or TALLY signal generator.

As preferred technical scheme, the rearmounted big TALLY lamp of described viewfinder is long rectangle fillet white PC housing, connects Shiny red bloom after receipts TALLY signal, is cameraman and personnel being shot provide instructor in broadcasting guiding signal.

As preferred technical scheme, described adjustable TALLY lamp luminance switch, is circular plastic housing, after adjusting manually Put TALLY lamp brightness, reach recorded broadcast scene application purpose..

The beneficial effects of the utility model are：This utility model solves the long-term dependence on import of video camera viewfinder, different Brand video camera can not general viewfinder, a kind of appearance of multipurpose viewfinder changes the market structure, television station, enterprise's electricity Platform, column group etc. need not rely on import viewfinder.
